Vulnerabilities Kia Sorento 2. Weaknesses, advantages and disadvantages of the second generation Kia Sorento

23.06.2020

The first generation Kia Sorento car, as well as its restyled modification, was assembled at the factories of Korea, and later in Russia (from 2007 to 2009), at the IzhAvto enterprise. Both versions are easy to recognize by the VIN code - "KNE" and "XWK", respectively. The car owes its popularity to its reasonable cost, as in the secondary dive. Bidding for six-year-old copies of the Kia Sorento on diesel fuel starts at 500 thousand, and for three-year ones - from 600. An interesting detail is fresh samples that are more expensive than diesel ones, while older ones are the opposite. This should be taken into account when choosing a power unit, because sooner or later you should think about selling.

As it should be in a typical SUV, the body is located on a powerful frame. Let this design be several times heavier than the supporting body, but it is more tenacious. This means that there should be no visible claims. However, paint chips may appear in advance on the hood of the Sorento, and rust blooms later. She also eats the “VIN” stamped on the frame spars, near the right rear wheel. If the stroke is damaged, complications during registration should be expected.

On modernized machines of the initial batches the air conditioning system often bothered. The reason lies in the inaccurately put on electrical connector - you need to push it tightly. There are cases when the power transistor responsible for changing fan speeds broke down. The element is inexpensive, and it will not be difficult to change it.

Operation and "sores" of Kia Sorento engines

On cars of the first generation, 2.4- and 3.5-liter volumes of the Sirius 2 and Sigma series were installed. It is also worth noting the diesel version of the "A-Engine" with a 2.5-liter volume. After restyling, the copy acquired a 3.3-liter gasoline engine from the Lambda series. As for the diesel, it remained the same, but its power rose to 170 instead of 140 forces. This was achieved through the introduction of other nozzles and capable of changing the geometry of the guide vane. As it turned out, the strength of the turbines has become much lower. If the former lived up to 120 thousand, then the new ones are even less.

After modernization on installations with a capacity of 170 horses more injector problems, namely with the bolts of their fastening. Fasteners often broke off and the nozzle fired from the engine, but for some reason more often from the fourth or third cylinder. If the bolt fell off the head - lucky. Worse, when together with the head: unscrewing the chip, you have to tinker. In any case, it is important to change the remaining bolts, even if they seem to be completely intact. For prevention, it is better to remove each nozzle every 100 thousand km. Because of the soot, this can be difficult to do. A simple trick: unscrew the spark plug and pour no more than 100 g of engine oil into the cylinder, then screw the spark plug into place and turn the crankshaft onto the pulley bolt. Sometimes a little effort is enough to get out and remain unharmed. Just do not forget to remove the oil from the cylinder later. And one more thing: be sure to replace the sealing rings.

Bosch fuel equipment is generally quite reliable. She, too, can be killed if only the car is filled with diesel fuel of a specific quality or the signal on the instrument panel is ignored, indicating the accumulation of a large amount of water in the filter sump.

The unit of the Sirius 2 line is equipped with a relatively complex shaft drive: one belt controls the timing, and the second balanced counterweights. If the repair of the first is treated with care, then the second is generally ignored. Some "masters" manage to set the marks of the balance shafts in antiphase, that is, they shift them from their true position by one revolution (the balance bar rotates twice as fast as the crankshaft). After that, the “non-main” belt wears out quickly and breaks. The "shaking" of the motor is not the worst. It is much worse when the crankshaft position sensor gets under the whip of the "ragamuffin".

The engines of the Lambda range are relatively young, but have already managed to get a floating malfunction - when idle speed rises for no reason and the annoying "" lights up. If you replace the throttle assembly, the lamp will go out.

The most unpretentious are the units of the Sigma series. available on the Hyundai Terracan. Despite the operational inconvenience, no typical breakdowns of the Kia Sorento were noticed. And yet, there is the same mediocre access to glow plugs as on Lambdas (replacement every 60 thousand, including timing and rollers). In addition, this family is very fond of "eating" fuel.

Transmission malfunctions Kia Sorento

Modifications with manual transmission it’s not enough on the domestic market, but almost everyone has one drawback: when the gas is released, the box rumbles in neutral gear - this is how the intermediate shaft walks in the supports, so you shouldn’t be scared. Experts are reluctant to eliminate the defect, since the selection of shims is quite laborious: the structure will have to be disassembled and assembled, and twice. But the hot nerves of the owners, dissatisfied with otherworldly noises, are cooled by the Kia Sorento. Clutch lives no more than 120 thousand km- The release bearing goes sour first. Under his whistle, you can drive no more than 10 thousand km, up to the service station.

Automated transmissions"Jatco RXC", as well as transfer cases "EST" with three modes, have good reliability. Just do not forget to change the oil fluid in a timely manner. But as for the three-mode "TOD", the clutches often burn out, which makes the car start to twitch in motion. The reason lies in saving the plant on oil. Sometimes, after filling on the conveyor, another 0.7 liters enters the crankcase.

Chassis, suspension, steering problems

There is practically no trouble with the running gear. Bushings and stabilizer struts will require replacement after 30 and 90 thousand, respectively. Front hub bearings live up to 50 thousand. Silent blocks, steering tips and ball joints last 150 thousand kilometers.

Brake pads serve no more than 40 thousand (does not depend on the type of transmission), both front and rear. Brake discs are enough for a couple of sets of pads, by three - much less often. If there are “drums” at the back (which is very rare), then you don’t have to worry about replacing them for 80 thousand km.

Video: 2004 Kia Sorento review ("The main road")

KIA Sorento is valued for its unpretentiousness, reliable power units and tenacious suspension. The Korean crossover has been produced since 2002, during which time three generations of the model have been produced. Until 2010, Sorento for the Russian market was assembled at IzhAvto, then in Kazakhstan and at Avtotor in Kaliningrad.

Sorento engines

The first generation of the car was equipped with a 2.5-liter D4CB diesel engine, as well as G4JS, G6CU, G6DB gasoline engines. The volume of the G4JS gasoline engine is 2.4 liters, and the power is 139 liters. With. G6CU - 3.5-liter unit with a capacity of 195 liters. With. It was replaced in 2006 by a 3.3-liter G6DB gasoline engine with a capacity of 247 hp. With.

The second generation of the model, which has been produced since 2009, was equipped with a 2.4-liter G4KE gasoline engine and a 2.2-liter D4HB diesel engine. Their power is 197 and 175 horsepower, respectively.

The third generation appeared in 2014. This is the Kia Sorento Prime. A D4HB diesel engine with a capacity of about 200 hp is available for the crossover. with., as well as G4KE for 188 liters. With. The line was supplemented by a 3.3-liter G6DB gasoline unit with 250 hp. With.

Sorento engine breakdowns

KIA Sorento gasoline engines are durable and rarely cause problems for car owners. Although each of them has characteristic weaknesses, certain features. All gasoline engines, starting with and ending with the G6DB, are ordinary aspirated engines that consume from 12 liters per 100 km in the city.

The pioneer G4JS on the Sorento 2.4 “digests” even domestic A-92 gasoline. It is prone to overheating in the winter season, which is due to the malfunctioning of the thermostat. The dynamics of a crossover with a 2.4-liter gasoline engine is mediocre. And with serious runs, over 200 thousand km, oil consumption begins. Of the features, it is worth noting the complex shaft drive, which includes balanced counterweights and requires competent maintenance.

More powerful versions of the G6CU and G6DB are equipped with a CVVT system and individual ignition coils, which are operated without problems in Russian conditions, despite the poor quality of gasoline. These engines are gluttonous. The 3.5-liter G6CU has a more outdated design and has proven itself well on the old Pajero. G6DB runs, depending on the quality of service and loads, from 300 thousand km. Then there is increased oil consumption, speed drops, increased noise. Sometimes owners of Sorento with a G6DB engine complain about floating faults. For example, from time to time the Check Engine error lights up, the idle speed increases. The problem lies in a faulty throttle assembly.

But not all Sorento engines are worthy of praise. So, the 2.5 CRDi D4CB engine, which was installed on the pre-styling versions of the first generation, is capricious in operation. With runs over 160 thousand km, starting on a cold one can become more difficult, interruptions in work begin, and the fuel system also presents unpleasant surprises. The nozzles are clogged with metal impurities, and scuffs appear in the high-pressure fuel pump. Partially, these problems are solved on cars manufactured after 2006. Thanks to restyling, the power of the internal combustion engine increased to 170 hp. With. Engineers have provided a new design of nozzles and turbines. This entailed not only positive, but also negative consequences. There was a misunderstanding with the nozzles, or rather, their fasteners, which can break off at a run of over 100 thousand km.

In 2009, the KIA Sorento began to install the G4KE with a capacity of 175 hp. With. This is an analogue of the two-liter G4KD gasoline unit, the resource of which exceeds 250 thousand km. Among the typical disadvantages is increased noise, some car owners are faced with wear of the liners, which can turn, which will lead to jamming of the crankshaft. This, as a rule, only happens with very intensive use. After all, erosion of the surface material of the liner occurs.

The diesel KIA Sorento with the D4HB engine is very frisky when compared with its predecessor, which was equipped with a 2.5 CRDi engine. Adherents of dynamic driving may encounter an oil burner. But this is the exception rather than the established practice.

What additives will be useful for KIA Sorento engines and fuel system?

The D4CB in-line four-cylinder diesel engine with a turbine and direct injection system holds 8.5 liters of oil. And in the D4HB engine of the new KIA, 6.7 liters of oil. Owners of Sorento diesel crossovers with these engines can be given the following recommendations:

Reduce the frequency of maintenance from 15 thousand km to 7.5-10 thousand km. Timely maintenance will save the life of the engine.
Since the internal combustion engine is turbocharged, after driving at high speeds on the highway, do not immediately turn it off. Let the motor run a little. This will extend the life of the turbine.
For processing a 2.5 CRDi diesel engine marked D4CB, use additives and. Make a double treatment, each time pouring 8 liters of additive into the engine. You can read more about this here.
To process a modern diesel 2.2-liter D4HB engine, use an oil additive. After running 400–500 km, repeat the procedure.

The repair additive will build up a dense layer of cermet on the working surfaces of the engine and extend the life of the turbocharger. Double treatment gives the following results: reduced oil and fuel consumption, increased compression, easier start-up at sub-zero temperatures. But keep in mind that the performance of the engine also depends on the health of the fuel system, the quality of the diesel fuel used.

The weak point in the KIA Sorento 2.5 CRDi is the copper o-rings of the injectors. If they are not changed in a timely manner, the injectors will need to be repaired. They are also clogged with soot due to the use of low-quality fuels and lubricants. This is a typical problem for most diesel vehicles that are operated in Russian conditions. Therefore, it is worthwhile to take a responsible approach to the choice of gas stations, and to increase the cetane index, add an additive to diesel fuel. This will reduce the load on the nozzles and prevent vanadium corrosion.

The maintenance schedule for gasoline KIA Sorento with G4JS, G6CU, G6DB, G4KE engines should also include preventive treatment with the RVS Master additive, which is simply added to the engine oil. This will fully preserve the performance of the engine, strengthen the friction units, and reduce the amount of noise and vibration.

KIA Sorento transmissions

The first generation Kia Sorento was equipped with a five-speed manual, as well as a four- and five-speed automatic. For the second generation of the crossover, a six-speed manual transmission and automatic transmission have been developed. The third generation of KIA Prime is equipped with only a six-speed automatic. Front- and all-wheel drive versions are available.

The four-speed automatic that was used on the first generation Sorento is the A44DE, made by the Japanese company Aisin. The components that fail during serious runs in the A44DE include an overrunning clutch, an oil pump, and a valve body. Later, instead of the outdated one, they began to use a more modern five-speed automatic transmission A5SR1 from Jatco.

Signs of breakdowns in the automatic transmission on the KIA Sorento can be considered jolts, kicks, vibrations, crunching when switching, howling and hum of the transmission. But the appearance of noise or knocking does not mean that serious repairs will be required, the replacement of the same valve body or oil pump. This will become clear only after a comprehensive diagnosis, troubleshooting.

If you want to extend the life of an automatic or manual transmission, use the RVS Master additive. For processing automatic transmission KIA Sorento is suitable. The additive is added directly to the oil, serves as the basis for restoring worn gears, bearings and other friction surfaces with a dense metal-ceramic layer.

But for the Sorento mechanics, you need or. The same compounds are used as an additive in the bridge and razdatka, which have characteristic weaknesses. For example, due to wear of the stuffing box, moisture penetrates into the junction of the transfer case with the box, which provokes corrosion, failure of the main pair of the transfer case, and the differential case in the transmission. This is a design flaw that the additive for the transfer case and bridge cannot solve. But on the other hand, she is able to restore worn-out friction surfaces, achieve easier and smoother operation of the transfer case, and eliminate the howl and rumble of the bridge.

05.10.2016

Kia Sorento), almost immediately after the start of sales, gained unprecedented popularity among crossover lovers. The first generation received a lot of criticism: for the oak suspension, poor handling and poor equipment; the second generation of the model, on the contrary, turned out to be a full-fledged crossover with impressive equipment. Despite the fact that the car is made in Korea, it is quite difficult to call it cheap in the initial purchase and further maintenance. But, if we talk about the number of technical problems, then in no case can we say that owning this car will cost a pretty penny.

Few facts:
Kia Sorento 2 is built on the basis, and was first introduced in 2009 at the Seoul Motor Show. The work on the appearance of the new Sorento was carried out under the guidance of the company's leading designer, Peter Schreyer, so in the exterior of the car you can easily see all the most striking features of the SchreyerLine concept, which have become the basis for the design of all new Kia models. Unlike the previous generation, which used a frame structure, Sorento 2 is built on the basis of a load-bearing body.
The interior of the new car has been completely redesigned - high-quality materials have been used for interior decoration, new functional details have been added, and the appearance of the front panel has been radically changed. Also, the list of options has expanded, which includes: a rear-view camera, a multimedia system with a 6.5-inch screen, a satellite navigator and a panoramic glass sunroof. In 2013, a restyling was carried out, as a result of which the power units and design of the car were finalized. In 2016, sales of the third generation started.

Weaknesses of Kia Sorento 2 with mileage

The paintwork of the car is not of the best quality, and therefore, the body is quickly covered with scratches and chips. But, despite this, the body resists the onslaught of the red disease very well. And if you meet a car with pockets of corrosion, then most likely its owner saved money on recovery after an accident. But the chrome elements of Kia Sorento 2, under the influence of reagents, are quickly covered with various pimples.

Power units

Kia Sorento 2 is equipped with one of the types of power units - gasoline 2.4 (175 hp) and diesel 2.2 (190 hp). As domestic operating experience has shown, both motors are very reliable, and there are few cases when the engine needed serious repairs. Basically, all problems are related to improper operation. For example, those who service the car under warranty and carry out routine maintenance on time know that candles need to be changed at least once every 30,000 km. But many owners do not support the warranty, and often delay maintenance, as a result, the engine starts to run unstable, and the “Check Engine” indicator lights up on the dashboard.

If you do not use high-quality oil, the crankshaft oil seal will begin to flow over time, and on machines with a diesel engine, the boost sensor fails. The biggest advantage of a diesel engine is that it painlessly tolerates the quality of our diesel fuel, also, I could not find a single review of the problems associated with starting the engine in severe frost. Fuel consumption, for diesel engines, in urban mode is 9 - 11 liters, on the highway - 5 - 6 liters. Gasoline versions of the car, in the city, consume about 13 liters of fuel (with all-wheel drive 15 liters), on the highway - 7 liters per hundred.

Transmission.

Transmission options include a six-speed manual and a six-speed automatic transmission. Paired with any of the power units, both mechanics and automatic can go. Very few cars with manual transmissions were sold. Now, in the secondary market among cars for sale, the number of cars with a manual box does not exceed 10% of the total volume of used Kia Sorento 2 sold. Therefore, there are practically no statistics on the reliability of mechanics. Automatic transmission is a classic hydromechanics and by modern standards, conditionally, it is eternal, and a run of 300 - 350 thousand km is not the limit. But in order for the transmission to serve you faithfully, change the oil in it at least once every 70,000 km, and at the same time, you need to drain the entire volume, and not half, as we very often do (you will need 11 liters of oil to replace) . If we talk about operational features, then, on some cars, when the lever is set to the “drive” position, the automatic transmission transmits vibration to the car body for a couple of seconds.

Versions with a gasoline engine can be both front-wheel drive and all-wheel drive, but with a diesel car, only all-wheel drive is available. Four-wheel drive is not permanent, but connected using an electromagnetic clutch. This system is quite reliable, but some shortcomings in it were still identified. So, in particular, the motors for connecting the coupling, as well as their wiring, are not famous for their durability.

Reliability running Kia Sorento 2

This model has a fully independent suspension - front MacPherson strut with anti-roll bar, rear - lever-spring, with telescopic shock absorbers and anti-roll bar. Most often, in the Kia Sorento 2 suspension, you will have to change the stabilizer struts (when driving around the city, once every 40,000 km, off-road - every 15 - 20 thousand km), ball bearings - 40 - 60 thousand km, thrust bearings - 60 - 70 thousand km. Wheel bearings and shock absorbers nurse 70 - 90 thousand km, CV joints and silent blocks - up to 120 thousand km. At 150,000 km, the brake hoses will need to be replaced. In the rear suspension, at least once every 40,000 km, it is recommended to lubricate the breakaway rod bolts, and if this is not done, then a grinder will have to be used during their replacement.

Salon

There are also minor comments on the interior trim materials of the Kia Sorento 2. So, in particular, scratches and abrasions quickly appear on glossy plastic surfaces, and even chips for not neat drivers. Not infrequently, the owners are bothered by the whistle from the air vents; replacing the cabin filter and lubricating the motor bearing will help fix the problem. If there was no outside interference in the electronic systems of the car, then there are no problems with it.

Outcome:

You shouldn’t expect any big emotions from this car, because with its driving style, the car looks more like a large comfortable leather sofa than a charged crossover for conquering off-road. Kia Sorento 2 will appeal to practical motorists who value driving performance and reliability.

Advantages:

Modern design.
Reliable engines and transmission.
Small fuel consumption.
Four-wheel drive.
Spacious salon.
A large number of options, starting with the basic configuration.

Flaws:

Not enough power for overtaking on the track.
Weak paint finish.
Rigid suspension.
The cost of servicing at an authorized dealer.
In winter, the interior warms up for a long time

If you are the owner of this car model, please describe the problems that you had to face during the operation of the car. Perhaps it is your review that will help readers of our site when choosing a car.

Change of oil

Engine oil is an essential element of every car's heart. This fluid provides lubrication of engine parts, and also removes 15% of the heat generated by the engine. But, like any other liquid, engine oil tends to lose its useful qualities, therefore, according to the manufacturer's recommendations, it is changed every 15,000 km.

Kia Sorento oil change process

Consider the basic principles of changing engine oil, with your own hands at Kia Sorento 2.4.

We install the vehicle on a flyover (pit or lift), and let it cool.
We carry out the dismantling of the lower motor protection.
We unscrew the drain bolt on the crankcase block. First you need to install a container under the drain.
After the liquid is almost drained, unscrew the oil filter and install a new element.
We twist the filler plug.
We unscrew the filler neck of the motor and fill in new engine oil.
After a break-in of 2-3 km, it is necessary to add lubricant to the motor.

Faults and repairs

At its core, the Kia Sorento 2.4 174 hp power unit. marked G4KE / 4B12 has no significant drawbacks. But, with all the pluses, he has malfunctions that occur quite often.

Dirty candles Kia Sorento

The motor starts running like a diesel. Injector contamination and structural features of the power unit. Particular attention should be paid to the contamination of the piston, as well as the formation of an air-fuel mixture.
Whistle in the engine compartment. These are all signs of an A/C bearing failure. Replacing the element will fix the problem.
Chirring. Many motorists start to get nervous, but you shouldn't. This is the normal state of the injectors.
Vibration at low rpm. This is a symptom of a bad spark plug. In this case, it is worth replacing the elements.
Quiet hissing sound. You should not think that a snake curtain in a car is the usual operation of a gasoline pump.

Gas per engine

In order to save money, many motorists want to install gas equipment. In this case, only propane is suitable, and then HBO is at least 4 generations. But, here, the question begins to torment: how will this affect the engine resource? It is worth considering a few facts that will help save an already low engine life when installing HBO:

HBO selection. A gearbox that can meet the engine's fuel demand at maximum load. Nozzles that accurately dose the mixture and have a low temperature dependence coefficient, an electronic control unit that allows you to fine-tune the composition of the mixture throughout the entire range of engine operation.
It is worth refueling only with high-quality liquefied gas. Of course, there is not as much of it as we would like, but it is worth finding a gas station whose gas meets the standards.
Cleaning/replacing filters. Be sure to carry out this procedure after no more than 10,000 km of run.
When carrying out maintenance, pay attention to the manifold and cylinder head gaskets.
The engine starts to consume more fuel. This is true. In the normal condition of the engine and a properly configured gas installation, fuel consumption will increase by only 10-15%. In this case, the consumption of gasoline will remain the same.

ECU and error codes

Most often, engine problems can be determined by the error codes of the electronic control unit. It is quite difficult to do this on your own, so it is recommended to contact the appropriate car service.

Of course, you can reset the on-board computer errors yourself. Disconnect the terminal from the battery for about 15-20-30 minutes (the longer the better) or use a trip computer like check-engine or Multitronics.

But the route must be bought, installed and configured. And anyway, they can’t erase all errors, so some errors can be stored in the computer’s memory, and CE will not light up.

Self-diagnosis

Also, diagnostics can be carried out using a paper clip. Let's get hold of a paper clip or a female hair clip. For women, it will not be difficult to find, but men will have to quietly take from their wives or girls.

Self-diagnosis pin

We open the hood. Find an air filter. Next to it is a diagnostic connector.

Engine compartment Kia Sorento

It does not have a plug, and therefore dust could accumulate in it.

Location of the diagnostic connector

See the wiring diagram.

Install a pin in the diagnostic socket

And we insert a paper clip into slots 12 and 19 so that the circuit closes.

We sit behind the wheel, start the key, turn on the ignition, but do not start the car.
First, the "Check Engine" light will be on for a couple of seconds and then go out. And her next flashes will mean error codes. Long flashes are tens, short ones are units.

Conclusion

Kia Sorento 2.4 with a G4KE / 4B12 engine is a Korean crossover with excellent technical characteristics. The engine is capable of delivering 174 hp, which is quite a lot. Since the power unit is designed on the basis of Mitsubishi, it means that this is the standard of reliability and efficiency. Along with all the pluses, there were a few flaws that do not interfere with the operation of the machine.

Kia Sorento is a mid-size crossover named after the resort town of the same name in southern Italy. The car was put into series production in 2002. Since then, three generations of the model have been developed, which equally gained popularity on domestic roads. The second generation has been produced since 2009. It is noteworthy that the basis of the Sorento's main competitor, the Hyundai Santa Fe, was chosen as the crossover platform. Three years later, the model has not undergone significant changes during the planned restyling. And already in 2014, Kia announced the start of production of the third generation of the crossover.

If the first generation was subjected to minor criticism: stiff suspension, uncomfortable handling, high cost for inexpressive equipment. That second generation of Kia Sorento, on the contrary, received a lot of laudatory reviews. The buyer was provided with a wide range of power units, various configurations of the crossover available to choose from. At the same time, the car is adapted to Russian operating conditions, which is an important help in choosing a quality vehicle. But, besides this, it is important to take into account the resource of power plants. In this article we will tell you in detail what is the resource of the Kia Sorento engine.

What engines are equipped with Kia Sorento?

The first generation of the crossover was equipped mainly with a 3.5-liter G6CU DOHC power unit with a capacity of 192 horsepower. The motor was aggregated with a five-speed manual gearbox or automatic transmission. In 2006, the manufacturer carried out a major upgrade of the model, adding several unique assemblies to the line of power plants. So the 2.5-liter D4CB turbodiesel engine became available for purchase. With the advent of the second generation of the Kia Sorento model, a new G4KE assembly appeared in the line of engines - an engine with a displacement of 2.4 liters, characterized by a power of 170 hp. It was this installation that later became the basic and most popular among all the available modifications.

G4KE features the following technical parameters:

16 valves;
4 cylinders;
injector power system;
motor resource - more than 250 thousand km.

The Kia Sorento EX package with a 2.2-liter engine is still very popular today. In general, the 2.2-liter engine was loved by many domestic drivers for its unpretentiousness and low fuel consumption. Initially, the unit had a capacity of 190 forces, but in 2013, during the modernization of a number of installations, its capacity was increased to 197 forces. At the same time, a diesel analogue appears.

Actual life of motors

Kia Sorento gasoline atmospheric power units are distinguished by the presence of a gas distribution chain drive and a water cooling system. Some modifications, for example, the 2.4-liter G4KE engine does not have, so it requires valve adjustment every 90-100 thousand kilometers. The G4KE motor is, in fact, an enlarged copy of the G4KD, as it includes a crankshaft with a piston stroke of 97 mm, which is 11 mm more than the younger versions of the unit. The timing chain itself is quite reliable, 100-120 thousand km pass without problems before replacement. The cylinder head of almost all engines is made of aluminum, which gives stability and endurance to the motors.

The only significant problem of the G4KE, G4KD, G4KJ is the turning of the crankshaft liners at the turn of 100 thousand km. Only connecting rod bearings are subject to cranking, but there were no claims to the indigenous ones among the owners of the crossover. However, the problem is rather isolated. Of the total number of car owners with similar engines, only 1% noted the problem. In general, it can be noted that the reliability of all Kia Sorento gasoline engines is quite high. With proper care, they can travel 300,000 kilometers.

But there has always been a specific attitude towards diesel in Russia. They are picky about the quality of the fuel they fill, and also require increased attention during maintenance. At the same time, Kia Sorento diesel installations are characterized during operation by the constant sound of camshaft tapping. Diesel modifications are difficult to repair, the main difficulties are associated with the accuracy of setting gaps. However, their actual resource is also quite large - 280 thousand kilometers. True, not every owner can reach this milestone.

Owner reviews

The first symptom of a malfunctioning turbodiesel modification, as a rule, is a whistle that comes from the engine compartment while the engine is running. Turbine repair is not a cheap pleasure, so it is important to diagnose all the breakdowns associated with it in time. It is recommended to replace the chain after 100,000 km, in extreme cases - after 115,000 km of run. It is undesirable to delay the replacement of the timing chain, since there are cases when it broke at 120 thousand kilometers traveled. To accurately determine what resource the Kia Sorento engine is, the reviews of the owners of the crossover will help.

Engine 2.2

Vasily, Ryazan. I have a car with a 2.2 turbodiesel engine, I bought a crossover after restyling. The car has already covered 120 thousand kilometers. I recently replaced the timing chain and that's it. There were no more problems or breakdowns. Cylinder head - reliable, well-made. At the service station they said that she was only afraid of overheating. If the arrow has gone into the red zone, then the probability of the need to repair the cylinder head is almost 100%. It is important to use only high-quality engine oil. This is the only way to keep the internal components of the cylinder head in perfect condition for as long as possible.
Stanislav, Cheboksary. I have been driving a Kia Sorento since 2013. At the moment, the mileage is 100,000 km. What is important to consider and observe? Of course, the quality of diesel fuel. I recommend refueling only at trusted gas stations. I myself prefer Lukoil, Rosneft, Bashneft, and there are also a considerable number of good fuel suppliers. Injectors suffer greatly from poor-quality "nutrition", the average life of the high-pressure fuel pump is about 200,000 km. As for the installation share. But the manufacturer himself assures that they go 150,000 km without problems. That is, this is a warranty resource, we throw another 100 - 150,000 km on top and get the maximum possible.
Igor, Moscow. I bought a car with a 2.2 CRDi engine with a capacity of 190 forces back in 2009. Today on the odometer the figure is 190 thousand kilometers. The engine is cool, economical and moderately high-torque, but, in my opinion, too noisy. Sometimes, it seems that you are driving a tractor. Maybe I'm wrong. But, at one time I drove many cars with a diesel engine, but I don’t remember that the engines worked so noisily. Replacing the timing chain was needed after 100 thousand kilometers. With its replacement, it is better not to pull, as it may break off and serious repairs will be needed. It also takes a long time to warm up. In winter, this is a necessary measure. Without warming up, it is extremely undesirable to go out on the road. I think that this engine is able to pass 250-300 thousand.

The turbodiesel 2.2-liter engine perfectly copes with the difficulties of operation on domestic roads. Its resource in some cases reaches the mark of 300,000 km. The main thing is to monitor the condition of the engine oil, air and fuel filters, and also not to neglect the planned replacement of consumables.

Engine 2.4

Egor, Voronezh. In 2008, I bought a Kia Sorento with a 2.4 liter engine. Passed already 200 thousand km. In my opinion, the most successful engine is the G4KE. This power unit copes with difficult operating conditions in Russia without any problems. It is important to monitor the condition of the filters and carry out timely replacement of consumables. I use original Hyundai/Kia engine oil. There were no breakdowns. I replaced the timing chain only once - it passed 120 thousand kilometers, it is undesirable to operate it longer, it can seriously stretch and break.
Vyacheslav, Moscow. I have a 2012 Kia Sorento second generation. I took the car from my hands, now the odometer is 180 thousand, I don’t know if they twisted it or not, but it seems to me that the mileage is quite real. The motor runs like clockwork. I have no complaints about the build quality. The oil does not “eat”, although many say that with a run of 200,000 or more kilometers, regular greasing starts. I don't know if this is true. So far, everything is in order. I think that 250-300 thousand km is a very real resource for the G4KE motor. By the way, this is almost an exact copy of the 4B12, which is equipped therefore, there is no doubt about its reliability and quality.
Alexey, Yalta. Personally, I did not like the car. More precisely, the engine itself is 2.4 liters. Up to 170 thousand kilometers everything was normal, and after the car literally fell to pieces. I changed the chain, injectors, crankshaft, oil cooler and other components. I had to spend a lot of time, effort and money. Maybe I got the wrong set. Even with the passage of the first 100 tyk, the liners began to rotate. At that moment, I realized that I could not avoid problems with the car in the future. In general, repaired, and then sold the car.

Kia Sorento with a 2.4 liter engine can be purchased without any fear. In extremely rare cases, there may be problems with turning the liners, early failure of the injectors. But, in most cases, these problems are the consequences of poor-quality service, neglect of the rules for passing maintenance. The G4KE engine with proper care covers about 300 thousand km.

Engine 2.5

Eugene, Rostov. I won’t discover America if I say that the resource of the Kia Sorento engine depends more on the quality of service. The 2.5 liter D4CB engine is very complex in terms of design. It's not that easy to repair. I myself have been operating Kia Sorento since 2002. Among the shortcomings of the motor, I note that it has a complex timing system of three chains with hydraulic tensioners. The chain in our operating conditions does not live long - 90 thousand, a maximum of 100 thousand. Very loud engine, the new 2.2-litre turbodiesel is much quieter. Antifreeze is best changed every 30 thousand, engine oil after 7-8 thousand run. I’ve already driven 220 thousand by car, there hasn’t been a major overhaul yet, the valves immediately bend with a broken timing chain, therefore, keep an eye on its resource.
Matthew, Yekaterinburg. The resource of a 2.5-liter engine is about 250 thousand - further overhaul. This is an almost identical company of the Japanese 4D56 from Mitsubishi. The Koreans added their turbocharging, changed the fuel injection system, and also upgraded the cylinder head and piston group. I will say that the engine actually failed to add the resource. It is difficult to repair it, many craftsmen say that it does not lend itself to capital. That is, you still have to find a good specialist. The timing chain is weak, it can break and bend the valves. He himself operated the Sorento from 2012 to 2015, after which he sold it.
Alexander, Vorkuta. Diesel is like diesel, nothing special. It works loudly when you start it "cold", it seems that the camshaft is knocking. It turns out that this is a feature of the operation of this engine. Do not leave without warming up, one plus is that it “eats” really little fuel. Weaknesses - copper rings are quickly destroyed, the liners also do not live long, the cylinder head does not like overheating. In general, the engine is not ideal, but it is quite acceptable for everyday work. The average resource is 250 thousand kilometers.

Like any other motor, the D4CB has its advantages and disadvantages. The main advantage of the engine is the need for a small amount of fuel. It is quite reliable, but in rare cases it produces more than its operational motor resource. On average, it serves for 250 thousand kilometers.

Engine 3.5

Kirill, Novokuznetsk. Probably many people know about this engine. It was also successfully installed on the Mitsubishi Pajero. I have had a car since 2017, I took it in the secondary market, it was made in 2004 (first generation). Mileage is already 240 thousand, no one twisted. Excellent performance, the motor has a lot of advantages, but there are also disadvantages. After passing 200,000 km, I constantly add oil - about 0.5 liters per 1,000 km. The chain is not the most reliable - 100,000 km is the limit of its resource. At the service station, experts say that 300,000 km is the ceiling of the resource. Then the speed starts to float, in general, it will be necessary to disassemble the engine and look at the condition of the cylinder block.
Daniel, Moscow. What I like about G6DB is that it doesn't have any bells and whistles, it's simple and thoroughly researched. Weaknesses and shortcomings: there are no hydraulic compensators, the gaps are adjusted manually, it works noisily on the “cold”, it is demanding on the quality of engine oil. I have a Kia Sorento 3.5L as standard. Mileage 210 thousand, recently began to add oil. Before that, everything was in order with the lubricant consumption. In general, the engine does not cause much trouble, there were no critical breakdowns.
Egor, St. Petersburg. I have a Kia Sorento with a 3.5 engine, exactly the same as the 6G74. I looked under the cover, everywhere there are Mitsubishi and Bosh marks on the sensors. Its main difference is that the block is made not of aluminum, but of cast iron. The motor cools down for a very long time, it is convenient in winter, it does not lose heat in 2 hours in the cold. The crossover has already traveled 250 thousand kilometers. There were problems only with the crankshaft sensor, I changed high-voltage wires and candles. There is also a belt, like a chain, to change with a roller after 120 tyk. There are no problems with topping up the oil, I'm surprised, although many say that this motor is characterized by an "oil burner".

Depending on the loads and quality of service, the 3.5-liter Kia Sorento engine is capable of traveling from 250 to 300 thousand kilometers. The undoubted advantage of the motor is its structural simplicity. It is easy to maintain and repair.
