Almost all cars have only front-wheel drive. All-wheel drive right-hand drive cars are rare, although technically they are nothing special. The knots are the same as on Murano and X-Trail, familiar and widespread. The clutch and its electronics are somewhat weak, but nothing more. For a passenger car that is not selected for serious off-road, nothing criminal.
In the transmission, in principle, there are no weak links, except for the actual gearboxes. The CV joints are strong and even the anthers do not tear for a long time. The hub assemblies are not the strongest, but they will have to be changed more likely due to the ABS sensors, which I mentioned.
From the factory, the car was equipped only with automatic transmission, but this does not mean that you will not find cars with “mechanics”. I myself saw Teana on a “handle” with a 3.5 engine, and there is reason to believe that such a transmission “swap” is not an isolated case. Still, don't count too much on this option. Almost all Teanas are either with a four-speed “automatic” Jatco developed by Nissan itself, or with a variator, which at the beginning of the 2000s was considered the latest “fashion”.
Actually, it is the RE0F09A variator (aka JF010E according to Jatco classification) on machines with 3.5 that is Teana's main failure. On the one hand, the use of a continuously variable gearbox made it possible to maintain and even significantly reduce the fuel consumption of the top-end engine - on the highway and in the city it is a good 15-25% more economical than the widely used junior 2.3.
And yet, the variator, although it seemed to be designed for high torque, does not “live” with a 3.5 engine. Despite all the efforts of designers to limit the load on the belt, it is still constantly at risk, and the working surfaces of the cones wear out very quickly.
Let's be honest: the owner of a car with a 3.5 engine is unlikely to deny himself the pleasure of sometimes "pressing down a slipper." Yes, even frosts ... But the variator does not like either sudden loads or cold driving. If we add here the irregular oil change in the box and the wear of the torque converter lining, it turns out that the resource of most automatic transmissions of this type with a 3.5 engine turned out to be very low.

Few problems? Add a relatively small number of cars with a CVT and a low level of literacy of craftsmen. There was simply no one to repair the broken unit, and the owners of the powerful Teans drank grief with a full spoon.
But structurally, the box differs little from the extremely popular RE0F10A and RE0F06A transmissions. They can be found on many models of Renault, Nissan, Mitsubishi, Chrysler and many others, where they have proven themselves well.
If you still bought a car with a CVT, and he is still alive, then change the oil as often as possible, once every 30 thousand, for example. Install an external filter on the box cooling system, monitor the thermostat. And try not to use the full power of the motor, do not skid under any circumstances and do not use engine braking modes.
Too many restrictions? Alas, otherwise the life of the variator cannot be saved. If you neglect the recommendations, then in addition to the general wear of the valve body of the box, there is a risk of failure of the pump pressure valve. Next, the box is waiting for shock loads, a quick break in the belt and damage to the cones, and at the same time the wear of the Forward clutch package.
With careful operation, the belt life will be about 150 thousand kilometers. Cases of running more than 200 thousand are rare, and the masters advise changing the belt proactively until it has worn out the cones. Friction notches on the belt wear out over time, it removes oil from the contact zone worse and begins to slide with less and less load, wearing out the surfaces of the cones and damaging them. And with long runs, the wear of the main steel belts affects - they weaken and thereby significantly worsen working conditions at large gear ratios of the box.
When buying, you should definitely check the operation of the box under load. With intensive acceleration, there should be no twitching, and even more so, noise from the transmission side; when driving at speeds of 90-130 km / h “on a cruise”, the tachometer needle should stand still without small fluctuations. When the load changes, for example, driving uphill, the speed should change very smoothly, almost imperceptibly. The inclusion of Drive and Reverse should be, again, soft.
Any problems with the variator - most likely, to high costs, because there are few contract units, and their wear is quite large. Repair parts are quite expensive. A belt - at least 30 thousand rubles, a restored oil pump - about 20 thousand. A set of shafts - already for 150 thousand rubles.
Cars with engines of 2.0 and 2.3 liters were equipped with a much more familiar automatic transmission, a four-speed hydromechanical RE4F04A. This box appeared on the Maxima and proved to be quite good. With normal maintenance, the mileage before the first repair is usually about 200 thousand kilometers. This was followed by repairs with the replacement of some solenoids and ... another 200 thousand before problems with the oil pump and serious wear of the clutch packs appeared. Against the background of the variator - a real salvation.

A typical disease is the loss of reverse gear. The Reverse planetary gear set is rather weak here - it cuts off the splines. However, this kind of breakdown is more typical for SUVs and crossovers with the same automatic transmission. The wear of the brake band affects primarily the smoothness of gear shifting 1-2 and the wear of the High and Forward Clutch packages. I already wrote about the features of controlling the pressure solenoid in the “electrician” section - changing the parameters of the “lowering” resistor also leads to hard operation of the automatic transmission. Other diseases of the automatic transmission - only with a combination of very poor maintenance and severe loads. Of the four-speed boxes, this is considered one of the most successful.
In practice, almost all drivers are forced to endure harsh switching 1-2, and in advanced cases 3-4, and even with a blow when turning on Drive / Reverse. Frequent oil changes and a good external radiator can increase the life a little. The reality is that this box, like all reliable units, is often tritely killed by a complete lack of maintenance and delaying the necessary repairs. I will repeat once again the old truth: “reliable” does not mean “indestructible”. There is nothing indestructible in modern cars.
Motors
The Nissan Teana J 31 was generally lucky with the engines. Nissan V 6 VQ series are famous for their good resource and good design. And the in-line "four" QR also proved to be a little worse. As for the general difficulties, first of all, pay attention to the cooling system. The quality of radiators is very mediocre, sometimes Chinese counterparts can withstand our salt and slush better. Even on cars aged 6-8 years, the owners noted the complete disappearance of the cooling fins in the lower part - they were corny eaten by corrosion. And by the age of ten, leaks often occur due to poor contact between plastic parts and metal, and the core of the radiator corrodes and flows.
Some difficulties with the engine compartment electrics are possible, but in general, everything is assembled well here. It is only necessary to monitor cleanliness and avoid large accumulations of dirt and oil emissions. Relatively weak catalytic converters need to be changed at the first sign of wear or after significant oil consumption for any reason - the exhaust here is quite thin and tuned. When ceramic chips appear, it goes into the cylinders almost immediately, leading to instant wear of the rings and piston scuffing.
Timing chain VQ23DE
original price
5 188 rubles
The simplest motor that can sometimes be found under the hood of the Teana is the in-line "four" QR 20DE. It is rare on Teana, but it is a very common motor for X-Trail and Primera. Not the best and most successful Nissan engine, but quite decent. The timing chain resource is about 100-150 thousand kilometers, it is quite stable and depends on the load on the engine. A timing revision is recommended for runs of about a hundred thousand, along with valve adjustment and checking the operation of the phase shifter.
The first series of engines were remembered by the early shedding of the catalyst already mentioned above and the subsequent scuffing of the piston group. And the motor is also characterized by a poor start in cold weather - at temperatures below -20 degrees, it stubbornly fills candles for any reason.
There are enough minor problems with unstable operation, vibrations and leaks. The resource of the piston group is about 200-250 thousand, after which you should expect an indispensable oil burner. But the sleeves change, and the pistons are relatively inexpensive. There were no catastrophic tricks with the loss of oil pressure behind it. It is not recommended to buy, because V 6 engines with much better performance and a longer resource were also installed on Teana. And in terms of fuel consumption, a two-liter engine is inferior even to an unsuccessful bunch of “3.5 + CVT”.
Most often, Teana can be found with a 2.3-liter VQ23DE engine. Despite the modest volume, there are 6 cylinders here. The more voluminous 3.5 VQ35DE differs minimally from it, but is less common.
These engines are considered one of the best engines in their class. A resource with proper maintenance is already over 400 thousand kilometers - real "millionaires of our time." There are quite reliable chains in the timing drive. There are three of them: one main and two chains connecting the camshafts in each of the cylinder heads. The main chain usually has a resource of more than 200 thousand.

Excellent traction, power, resource and also the ability to boost. And at the same time, they are very conveniently arranged, have a small mass and are compact. Of course, it is not without difficulties. So, a bad start in winter is as common as on in-line "fours". And on engines until 2008, the catalysts died quite early. If the problem was not fixed under warranty or they were not removed at all, then problems with increased wear of the piston group are also possible.
The oil consumption of the engines is slightly higher than average - the not very advanced crankcase ventilation system, the high average mileage, and the design of the piston group also affect. But if the motor consumes within a couple of liters from replacement to replacement, then you should not worry. This is quite typical and consumption will not progress rapidly anytime soon. The engine usually forgives even small overheatings without air pockets, the main thing is not to miss the oil level and change it every 10, maximum 15 thousand kilometers, at least. Dirty oil quickly kills the oil pump and dramatically increases the gaps in the timing mechanism - they also require adjustment here, at least once every 60-80 thousand kilometers. And the appearance of steam locks with serious overheating can lead to warping of the cylinder head or valve cover.
Candles are recommended to be changed more often - you can put not platinum, relying "by rank", but ordinary ones, but with a replacement at least once every 40 thousand. In this case, the ignition modules will live longer, and the course will be smoother, and the return will be higher. To replace the rear row spark plugs, you need to remove the intake manifold, but the procedure looks scarier than it actually is.
Also, to maintain comfort in the car, it is recommended to change the engine mounts every three to four years - the motor is sufficiently vibration-loaded, so the wear of its suspension elements is significant.
Vibrations are also associated with the Teana-specific problem with wiping the fuel hose. Check the engine compartment for the gasket of this important element - fires happen, and most often in the left side due to gasoline getting into the exhaust under load.
Oil leaks on these engines occur regularly: camshaft position sensors on the cylinder head, candle wells and valve covers flow. This trouble is treated by cleaning and replacing the ventilation system, but be careful, this is the first sign of serious wear on the piston group of the motor. If the upper catalysts are in place, then they are likely to crumble, and the wear of the piston group is already serious.
Pictured: Nissan Teana (J31) "2003–05 In general, the “perpetual” motor also has difficulties, so cars with a “junior” V 6 should also not be taken without looking. However, the choice of contract units is very wide, in case of serious trouble with an old engine, it is easier to buy a used one in good condition - the probability of finding a good copy is very high.
So take it or not?
Business class at this age is usually not cheap to operate. But Teana is happy in this sense: if you buy a car with a 2.3 engine, then the risks are minimal. Yes, a four-speed automatic transmission is an obvious anachronism; by 2008, seven-speed automatic transmissions were already installed on European cars ... But everything works reliably - both the engine and the gearbox.
Pictured: Nissan Teana (J31) "2006–08 The most painful place - the body - can still be maintained in good condition, just at a slightly higher cost than the "best examples". Do not think that European models are even a little more recent, they have even more problems in this regard. Cars with rings on the radiator grill and with a star rot, and sometimes much faster and more unpleasant.
Serious disadvantages include the poor quality of the interior, a mediocre multimedia system and “cotton” handling. Yes, and the suspension requires regular maintenance.
But if you calculate, then all the minuses overlap with a large margin. Especially if you are not a connoisseur of fine handling, do not require a powerful car to consume fuel like a small car, and are not used to European ergonomics of premium brands. The eternal trouble of the model is that the main competitor of Teana is very strong. Toyota Camry is indeed better in almost all respects, it plays in the same class, and its list of advantages is very similar. True, the price of Toyota will be almost one and a half times higher; people's love “warms up” it. There is something to think about, isn't it?
Would you buy yourself a "first" Teana with mileage?
Today we will talk about such new cars as Nissan Teana 2008-2014 release, this is the second generation of the model, the J32 series. Teana is a follower of the legendary Nissan Maxim, which was considered a very reliable car.
Now we will see if the Nissan Teana can also be considered a reliable car, like its predecessor Maxim.
What Nissan can't take away is their reliable VQ-series engines: a 3.5-liter 6-cylinder engine and a 2.5-liter VQ25. These motors can easily withstand 350,000 km. run. There are approximately 68% of cars on the market with 2.5-liter engines and 22% of cars with 3.5-liter engines.
What these engines are afraid of is "singed" gasoline, because of which the oxygen sensors will immediately fail, and overheating. When you see while driving in a traffic jam, with the air conditioner on, that the temperature of the engine is rapidly increasing, this means that you need to urgently clean the radiator cells, which are probably clogged. To do this, you need to remove the radiator, and, so that nothing interferes, clean it. It is advisable to do this procedure after every 60,000 km. run.
If the temperature needle jumps when the engine is warm, and it suddenly blew cold from the stove, then you need to make sure that everything is in order with the radiator, that it has not flowed in the place where the junction with the tank is. A new radiator, by the way, costs about $300. In general, in any such doubtful case, you need to go to a service center, let them check what's what, because if there are air pockets in the cooling system, then you can ruin the engine if it overheats. A cylinder head repair- the case is expensive, it will cost no less than $ 2,000.
There is also an in-line 4-cylinder engine of the QR25 series, the volume of which is 2.5 liters, such an engine is installed in about 10% of cars. This engine also works in the Nissan X-Trail, it is a fairly reliable engine, but it is much weaker than 6-cylinder engines, which even last longer. In this four throttle assembly requires periodic cleaning, and also, the timing chain after 150,000 km. stretched and needs to be replaced. As for the "sixes", their chains can easily withstand 250,000 km. run.
Transmission
Teanu, with both 2.5-liter engines, comes with Jatco JF011E CVTs, the cost of a new one is $ 5,600. These CVTs easily serve about 200,000 km. if you change the oil on time and do not force the car much.
There is another variator that was installed in the Nissan Maxima - Jatco RE0F06A, it had a number of its own problems: the stepper motor broke down, after which the gears did not change, and also, this box often overheated. But these problems concern the early models of Teana. Usually, after 120,000 km, a hum appeared while driving, which said that it is necessary to change the bearings of the driven and driving shafts, which cost about 60 dollars per piece.
It also often happened that the belt required replacement after 100,000 km., Because, for the variator, active driving and “sticking” into the curb badly affect. Replacing the variator belt will cost $ 300. In cars manufactured after 2010, the variator has become stronger, and the control program for it has also been changed. By the way, those who have an early version of the variator installed in Teana can do a transmission chip tuning, after which the car will feel better.
In general, cars with a CVT also don't like driving in traffic jams, because at low speeds, the CVT has to work more time with a high gear ratio, which means that a sharp belt bend is kept on the drive pulley. From such work, the belt wears out faster, and its chips eventually clog the oil pump valve, which leads to oil starvation, and then an expensive repair of the variator, which will cost $ 2,500. Therefore, in order to avoid such huge expenses, one must carefully monitor the operation of the variator and as soon as you feel tremors, the first thing you need to do is change the gear oil. In this case, this is Nissan CVT Fluid NS-2, it will require 8 liters, which will cost $ 110. And for one filter, you also need to change - another 60 dollars.
The CVT, which works in tandem with a 3.5-liter engine, uses an aluminum sump with a radiator and a separate oil filter to ensure better heat transfer. And on CVTs that are installed in cars with 2.5-liter engines, there is an ordinary steel pan, and the oil pan is installed inside the heat exchanger.
For "Tean", which have a 3.5-liter engine, another variator is used - Jatco JF010E, the price of which is $ 5,700, it is designed for higher torque. But he likes a calm driving style. After 150,000 km. it is better not to wait until the belt breaks and change it.
There are cases that after 100,000 km. the power steering may fail, this, of course, is not the most serious problem, but still periodically check the high pressure hose for integrity. Since this hose runs next to the hot exhaust manifold, it dries out very quickly and bursts over time, a new one will cost $ 200.
You also need to monitor the fluid level in the hydraulic booster, because, even with the slightest leak, the power steering pump can break down, which does not tolerate air entering the system. Replacing this pump will cost $380. In addition, such a sensitive pump can spoil even very sharp steering movements in cold weather with still cold oil.
And even washing the car under pressure, if ignorant, can help this pump fail earlier. An interesting observation is that the power steering fluid reservoir is located near the edge of the right fender, and if you pressure wash the car and the lid in the reservoir is not hermetically closed, then dirt and water can enter there, which will lead to blockage of the pump valve. Therefore, for cleaning it is necessary install additional o-ring into the working fluid tank. By the way, in cars manufactured after 2013, such a ring has already been introduced into the design.
Other parts in the chassis do not present any particular problems. Despite the fact that the steering rack is quite expensive, it will not require replacement, even if it has been tapping for several years. You can change inexpensive anti-roll bar bushings, $ 6 apiece, after about 50,000 km. By this run, stabilizer struts are already starting to knock, their replacement will cost 20 US rubles, and tie rod ends, at $ 40 per piece. But these are all trifles compared to what you will have to spend money on after 100,000 km. - shock absorbers: both rear will cost $ 200, and the front will cost $ 500. Next, you need to replace bearings, which come with the hub - $ 320 for the front, and 480 for the rear. You will also need to spend $ 100 on a set of strut support bearings.
Silent blocks on the rear suspension and levers are considered the strongest, they can easily withstand about 200,000 km. run. But by this time, you will have to spend $ 800 to make a replacement for these parts. Just like silent blocks, the ball joints that come with the front levers are reliable and can withstand about 200 thousand and together will cost $ 340.
Pre-styling models assembled in Japan before 2009 have a weakness to "deflate" over time. The reason for this is the weak rear springs, their replacement will cost $ 180. If they are not changed, then the ground clearance will decrease so much that the car will start to cling to the muffler, which is also not cheap - $ 200. With sagging springs, it will even be possible to hook the taillights. For example, on a speed bump, the rear overhang clings, after which the bumper rises and damages the edges of the headlights. New taillights are not cheap - $ 160 for one headlight. So, in the car everything is interconnected, the springs sagged - the headlights and the muffler will have to be changed. As for cars assembled in Russia, they don’t have such a clear problem with springs, because longer springs are used, which made the car 2 cm higher in the back and 1 cm in front.
Body features Teana
Teana's body also "gives a light" to its owners. Even in winter, during moderate frosts, the castle can simply freeze, that's how thermophilic it is. Those who have already encountered such a situation know that it is necessary to prepare the car for the winter and lubricate door mechanisms with frost-resistant grease. And already in the spring there are situations when the drainage pipe of the hatch is clogged, because of this, condensate will form, which will ruin the ceiling upholstery.
But the main problem of the body is that the “Tean” has a very delicate paintwork, chips appear very easily, on which rust then appears. The chrome with which the car is trimmed is also easily scratched, especially on the "Japanese", Russian chrome, and the paintwork is stronger.
By the way, Teana is difficult to identify with the help of a thickness gauge for participation in accidents in the past. Body parts could be straightened and repainted even under warranty, and it will not be visually visible that the car was in an accident.
So, Nissan Teanas are not so problem-free, they also bring worries to their owners. Even the main competitor in the market - in the back of the V40 is more unpretentious. True Camry is about 70,000 rubles more expensive than Teana. But on the other hand, these “Japanese cars” are clearly ahead of the German competitor in the class, the Volkswagen Passat B6, in terms of reliability. If you decide to buy Teana J32, then it is best to take a car after restyling, assembled in Russia, with an improved suspension. But we must be prepared for the fact that over time the car will have to be tinted.

Faults and engine repair Teana / Murano / 350Z / G35 / FX35 VQ35DE
The VQ35 engine is one of the most popular Nissan engines, the owner of various awards as the best engine of the year. The engine replaced the 3 liter VQ30DE, belonging to the 1st generation VQ. The new 3.5 liter engine, in the most common modification, has a power of 280 hp, but depending on the model, this parameter can vary from 230 to 250 hp. on the 2nd generation and from 260 hp up to 300 hp on the 3rd generation. The differences between the two variations are in the intake manifold, cylinder head channels, reinforced cylinder block, less rigid valve springs.
On the technical side, the engine was initially equipped with a forged crankshaft and connecting rods (length 144.2 mm), pistons coated with molybdenum (compression height 30.1 mm), a variable valve timing system with phase shifters on the intake shafts (CVTC) is used. Camshaft characteristics: phase 240/238, rise 9.57/9.57 mm. On SUVs, camshafts were installed with a phase of 230/232, a lift of 9.0 / 9.0 mm. There are no hydraulic compensators on the VQ35DE, valve clearances are adjusted by selecting a pusher every 100 thousand km, but in practice, motors can roll back much more than 100,000 km and the gaps will remain normal. The VQ35 timing system uses a reliable chain.
For the Nissan 350Z 35th Anniversary Edition and some Infiniti G35 V35s, the VQ35DE Rev up engine was released, featuring a variable valve timing system for intake and exhaust camshafts (CVTC), as well as the camshafts themselves. Their characteristics: phase 248/248, rise 10.59/10.59 mm. A short intake manifold was used. Such engines could be turned up to 7000 rpm and they produced 298 hp. at 6400 rpm.
In 2006, a modified version of this engine appeared - VQ35HR, used mainly by Infiniti. These installations were distinguished by a variable valve timing system on the intake and exhaust camshafts. The characteristics of the camshafts have been changed to the following: phase 248/248, lift 10.54/10.54 mm. Reinforced valve springs and larger diameter valves were also used. The cylinder block was also redesigned (its rigidity and height were increased). Long connecting rods (152.2 mm) were installed in it, new lightweight pistons, the compression ratio increased to 10.6. The intake system and inlet channels are completely different, equal-length manifolds are installed on the outlet. The VQ35HR motor spins up to 7500 rpm and develops 306 hp. at 6800 rpm.
Together with this engine, other engines related to the series were also produced: VQ20, VQ23, VQ25, VQ30, VQ37, VQ40.
Since 2007, the VQ35HR has been replaced by the 3.7 liter VQ37VHR.
Problems, weaknesses and malfunctions of Nissan VQ35 engines
1. High oil consumption. Catalysts are the root of evil here, on this engine they are sensitive to the quality of gasoline and can quickly become unusable, simultaneously clogging the lower catalysts with ceramic dust, and after this sand enters the engine and grinds off the cylinder walls, compression drops, oil and fuel consumption increases, interruptions appear in the operation of the engine, the car constantly stalls, does not start right away, etc. The issue is being resolved by overhauling the VQ35DE or replacing the engine, plus the purchase of four new catalysts. To prevent such troubles, you need to immediately go and change the upper catalysts to flame arresters, this will reduce the toxicity standards, but the above problem will bypass you.
If it's not the catalysts, then look for the problem in the oil scraper rings.
2. Overheating VQ35DE. The problem is not frequent, but there is a place to be and its consequences are warping of the valve cover, leading the head, etc. Check the radiator tanks for leaks, the cooling system for air pockets, clean the radiator.
3. Unstable idle on VQ35HR. The most common cause is the exhaust camshaft covers, check and replace them.
All other problems and malfunctions are not of a systemic nature and arise from operating conditions. The VQ35DE engine itself (and VQ35HR) is reliable as a hammer, has a huge resource and runs more than 500 thousand km during normal operation. Definitely recommended for purchase.
Engine Tuning Teana / Murano / 350Z / G35 / FX35 VQ35DE
Chip tuning and atmosphere
This motor has enormous reserves to increase power and it is a sin not to use it. You can go for chip tuning and add ~10 horses to yourself, but having such an engine is not entirely reasonable. Our task is to seriously increase power, and this cannot be achieved without horse shafts, so we order camshafts with a phase of 272/272, split gears, connecting rod bolts, a forged piston with increased coolant, 440 cc nozzles, we make cylinder head porting (this gives improved cylinder filling and removal exhaust gases, due to boring and polishing of the inlet and inlet channels). Also needed are larger valves, springs, an intake receiver (often used by Kinetix), a cold air intake, two spiders of equal length, a forward flow exhaust, a Motek brain. At the output, you can get up to 400 hp, it is important to use high-quality components, otherwise the result may not meet expectations. The cost of building an evil aspirated VQ35DE is very high, so the majority of tuners follow the path of supercharging, which we will talk about below.

For supercharging, you will need a forged SHPG with a low coolant (about 8.5-8.8) and sleeves, at a pressure of up to 0.4 bar, the SHPG can not be changed and the block cannot be lined, you will need an amplifier for the cylinder block, the compressor kit itself (to your taste), shafts with phase 256 , 600cc injectors, cylinder head porting, Walbro 255 fuel pump, straight-through exhaust. On a standard piston and 0.4 bar boost, we get up to 400 hp. About 400 hp can be removed to the piston stock. from the wheels, and on the VQ35HR engine even 450 hp.
On a forged piston and more powerful charger, 450 hp can be removed. and more, depending on the type of compressor and the availability of a stroker kit.
Turbo kit on VQ35DE. VQ35DET. VQ35DETT
For proper turbocharging of the VQ35DE, the above configuration on a forged piston with liners is suitable, instead of a whale compressor we use a turbo kit, the power will be about 450-500 hp. and more, depending on the type of turbines used. The VQ35DE engine allows you to remove more than 1000 hp, but for this you need to replace a lot, besides, such projects are single and it makes no sense to talk about them here.
The mid-size Nissan Teana sedan in the L33 body (3rd generation) is based on the upgraded D platform, which also forms the basis of the overseas twin, the Altima model. The car body is made with a wide use of high-strength steels, the content of which reaches 50%. The Nissan Teana suspension scheme has not fundamentally changed during the last generation change: MacPherson is still located in front, and a multi-link is in the back. However, certain adjustments were made to the configuration, some elements received other settings.
On the Russian market, the four-door is offered with two power units: a 2.5-liter “four” QR25DE from and a 3.5-liter “six” VQ35DE. The revised four-cylinder engine has a new block head with integrated injectors, phase shifters on both camshafts, and a variable length intake manifold. The output of the unit is 172 hp. (234 Nm). A V6 engine with a Russian specification aluminum cylinder block develops a maximum of 249 hp. and 312 Nm.
Each of the motors is aggregated with a variator, but here we are talking about transmissions with different designs. So, a less powerful motor works with a box using a belt drive. A more voluminous and high-torque 3.5-liter engine received a variator with pulleys interconnected by a chain. The difference also lies in the gear ratios: in the first case, they are in the range of 2.631-0.378, in the second - in the range of 4.130-0.383.
Differences in the traction parameters of the engines and the technical characteristics of the gearboxes determine the difference in the dynamics of the two modifications of the Nissan Teana. A sedan with a 2.5-liter engine, when accelerating to 100 km / h, barely gets out of 10 seconds, spending 9.8 seconds. A car with a 249-horsepower "six" is much faster - it takes 7.2 seconds to spur to 100 km / h.
The fuel consumption of the Nissan Teana 2.5 version is 7.5 l/100 km. Modification with a 3.5-liter power unit consumes about 9.3 liters.

An urban mid-size sedan from the Japanese automaker appeared to the world in 2003, replacing two models - Cefiro and Laurel. Nissan Teana immediately came to the court of buyers, including Russian ones. And to this day, sales in the secondary market are already at a good level. During its history, the model had three births and two upgrades in the first and second generation. Already in the second incarnation, the car was transferred to business class and, rather, has an intermediate position between D and E-class. From the predecessor of the premium Nissan Maxima, a line of J codes was received, which ended in 30.
The idea to combine austere luxury, maximum comfort, power, quality, exceptional safety, attention to detail and the dynamism of sports cars has received a delightful embodiment. In addition, impeccable sound insulation, smooth running, excellent handling, expensive finishes and a wide range of functionality are the hallmarks of the Nissan Teana.
1st generation (02.2003 - 01.2008)
ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!
The first birth of the J31 machines lasted 5 years from 2003 to 2008 and was produced in Japan. The first two years the car was not presented in the Russian Federation. The restyled version of 2005 officially entered the Russian market in December with three engines - a 2.0 four-cylinder for 136 horses and two six-cylinders (pictured), whose volume is 2.3 liters, producing 173 hp. and 3.5 l 245 strong.
Of course, with such a mass (1456 kg), two liters is not enough, so in those years the baby got the role, for the most part, of a corporate and personal vehicle for middle managers. The 3.5 power unit is paired with an XTRONIC CVT-M6 continuously variable transmission, which can be manually shifted to six fixed gears.
The other two are equipped with a 4-speed automatic transmission. Summarizing, we can say that the front-wheel drive five-door five-seater business sedan already at the start gained recognition and gained popularity, demonstrating sales, and this is the best review.
2nd generation (February 2008 - August 2011)
Russia became the first country of official sales of the second generation Nissan Teana - J32. The manufacturer's plans are so ambitious and adventurous that the wealth of trim levels, including all-wheel drive, is amazing. Engineers and designers did their best, taking as a basis the unremarkable body of the first incarnation, adding beauty and elegance.
The new Nissan D platform provides improved ride comfort, handling and safety. The interior has been improved in the direction of comfort and convenience - even less noise from the outside, more space above the head, on the sides and for the legs. Along with a wide selection and availability of 4WD, the price for the E-segment is quite acceptable.
Now under the hood is a 2.5 or 3.5 petrol V6 engine with a capacity of 182 and 249 hp. 
In addition to the six, there is an all-wheel drive specification on which the motor is placed - an in-line four 2.5 (170 hp). All versions come with a new CVT with XTRONIC CVT electronic shift control.
Generation 2 changes (09.2011 - 02.2014)
As a result of Nissan's September 2011 facelift, the J32 saw the 2nd generation 4WD vehicle fitted with X-Trail's All Mode 4x4 all-wheel drive scheme, which added confidence on the road.
The appearance practically repeats the front-wheel drive configuration with the addition of some design decorating solutions that give grace, nobility and sport. For Russia, the assembly is organized at the Nissan plant in St. Petersburg.
3rd generation (03.2014 - 05.2016 for the Russian Federation, for Japan until 2017)
Nissan Tiana received a third birth, and in March 2014 saw the light of L33. Compared to its predecessor, significant changes have taken place - all the best qualities have been brought to perfection, anticipating expectations with a margin and taking into account shortcomings. Nissan presented a chic luxury, representative car with a complex, interesting, not boring design, at a price lower than its competitors. 
In the new incarnation, every line is impeccable, where everything is harmoniously combined and endowed with exceptional taste using the most modern technologies, and sizes brought to business standards. In addition, the L33 has the smallest turning radius in its segment of 5.7 meters.
Russian Nissan car dealers offer the buyer two familiar power plants - a 2.5 inline four with a capacity of 173 hp. on all trim levels and a 3.5 V6 with 249 horses on top-end Premium and Premium Plus specifications. Both units are improved in terms of gasoline consumption. The transmission on both units is a variator.
What engines were installed
By the volume of the power plant, you can judge the price of the vehicle. The higher the cubic capacity, the larger and heavier the horse. Accordingly, manufacturers seek to match the motor to the price. The higher the cost and prestige, the stronger the engine and more liters. So, the cubic capacity of the Nissan Teana engine is from 2.0 to 3.5, producing from 136 to 252 hp.
Which engines are the most popular
The most popular unit in the L33 was the base volume of 2.5 liters, because its power is 172 hp. quite enough, no compromises - and the price tag is excellent and in operation the same dynamics and excellent quality, and fuel consumption is less than a 3.5-liter.
J32 are also in demand among our compatriots. There are many offers and a wide range of second-generation machines on the secondary market. The 2.5L is still the top choice, but the more powerful 3.5L are plentiful, indicating demand. 
As for the J31, the 2.3-litre was the bulk of sales, along with roughly the same choice between 2 and 3.5-litres.
With which unit to choose a car
All Teana's six-cylinder engines are successful. It matters how, where and how much the vehicle was operated. Reliable, powerful and economical VQ series 25 35. Their resource is 350 thousand km. Approximately 70% of commercial vehicles are 2.5 and 20% are 3.5 liter. Gasoline 4-cylinder two-liter QR-series are a rarity, but if you find one and decide to buy, approach the final decision very carefully and critically.
Most often, these are former corporate horses that were used “both in the tail and in the mane”, and were serviced with a peculiarity of the Russian mentality - not mine, it’s not a pity. Of course, you can buy and install a contract ICE. Replacing an old node with a new one involves removing the mechanism, so do not try to do it yourself if you do not have such skills.
Features of operation in Russia
The danger to the heart of the Japanese is low-quality gasoline. Its use immediately leads to overheating and damage to oxygen sensors. While driving in a traffic jam with the air conditioner running, when braking is constantly replaced by slow driving, the temperature of the internal combustion engine will begin to rise rapidly. This means that the radiator cells are clogged and require urgent cleaning. For the same reason, or when refueling with a low octane rating (92 instead of 95), the internal combustion engine knocks. 
Driving in traffic jams and CVTs is bad. At low speeds, it has to work excessively at a high gear ratio, which wears out the belt and further leads to oil starvation and damage to the mechanism, which will cost $ 2,500 to repair. Don't expose yourself to spending when you can avoid it. As soon as you feel jolts, change the gear oil and filters. With adequate driving and regular oil changes, CVTs of this model will valiantly last 200 thousand km.
The poor quality of the roads and the frequent hard contact of the bumper on the curbs and speed bumps breaks the plastic protection of the engine - anthers.
ICE troit. Perhaps the most common malfunction of any power unit occurs regardless of age, equipment, kilometers traveled, and even condition. Tribling means uneven operation of the cylinders, which, in turn, leads to the fact that the working mixture does not burn out in the chamber, lights up with a delay or does not burn out completely. If one of the signs of a “disease” appears, you should immediately go to the mechanic for diagnosis for treatment.
- At idle, the engine jerks and shakes. Sometimes so much that it is transferred to the steering wheel.
- While driving, power drops, jerks appear during acceleration and dips when you press the gas. The check lights up.
- Exhaust pipe sound
