Common problems and illnesses Infiniti QX56 Z62
How problematic is Infiniti with mileage?
The first and main thing that is full of all the reviews of the owners is increased wear of timing chains. In fact, this problem is not related to any miscalculations of engineers in the engine, but is simply the result of the supply of defective chains to the manufacturer's factory.
This shortcoming is recognized by the Infiniti representative office as massive and a free replacement of timing chains is carried out under a recall campaign. In other words, defective fast-stretching timing chains on the QX56 are NOT a problem. You can find out if a certain Infiniti QX56 or QX80 is eligible for chain replacement by calling any Infiniti OD.
When inspecting the Infiniti QX56 before buying it using computer diagnostics, you need to find out the angles of the intake and exhaust camshafts under load and idle time - this will allow you to find out the degree of stretching of the timing chain and the need to replace it. It is also worth bothering to ask the seller (if he is the owner) about the documents for replacing the chain, if it was carried out. Without documents, there is no point in believing sellers, as well as believing outbids.
We emphasize that the replacement of timing chains at the Official Dealer is free of charge, you are not obliged to agree to the replacement of any other parts that the dealer “recommends” to be replaced. Usually, ODs try to lure customers into additional work to replace oil scraper rings and caps. In addition to the chains, there is a recall campaign to replace the rear control arms and fuel gauge on the QX56 and QX80.
Important! Only "racing" operation on a stretched chain leads to chain jumping and further internal damage.
The second widely discussed problem of the Infiniti Qx56 is the oil burner and oil starvation. There are a lot of unconfirmed and invented cases about this. First of all, it must be said that oil waste for VK56VD engines is the norm. The average oil consumption for 100 thousand kilometers of the real run of the Infiniti Qx56 car is 1-1.5 liters of oil per 10,000 km.
Because of what happens oil starvation QX56 Z62 (VK56VD)? Infiniti QX56 and QX80 do not have an electronic engine oil level control system, i.e. no electronic probe, therefore, it is not uncommon for owners or repurchases, riding before sale, to Infiniti QX56 with high mileage do not monitor the oil level and are not interested in it in principle. As a result, you can get scoring of the working surfaces of the cylinders or beds of the RV or liners of the CV.
Low oil level and/or constant aggressive operation leads to local engine overheating. Overheating is very unpleasant for this motor, because. in addition to standard troubles and increased wear, direct injection and catalysts suffer. To check for symptoms of an overheated engine before buying, you need a long test drive, as well as an inspection of the inside of the engine with an endoscope through the oil filler neck.
QX56/QX80 Z62 Catalyst Problems
Ceramic crumb in cylinders and badass
Does VK56VD pick up motors? Despite the alusil coating of the cylinder walls of the aluminum block head, this otherwise cast-iron engine has few cases of scuffing and is associated with high mileage and overheating, and not wear of the catalysts.
There are numerous reviews from Infiniti Qx56 owners with mileage indicating more frequent death of catalysts on this car than on the rest of the brand line. Considering that the catalyst material is identical, and the manufacturer has not changed, this situation may seem extremely strange.
In fact, everything is much simpler - the fact is that for engines VK56VD direct injection(QX56, QX80, M56, Q70S) a more advanced and smarter engine ECU is installed. Algorithms of the new ECU allow to determine the reduction in the efficiency of catalysts earlier, compared to older versions (for example, VK56DE for QX56 of the previous body, or all FX35 FX37).
As a result of earlier algorithm firings, the end users of the car think about the lower reliability of the catalysts, when in reality, on other cars, the self-diagnostic system is simply not aware of the state of the exhaust line elements.
In most cases, if an error occurs in the low efficiency of catalysts, there is no direct need to replace them or uproot them with flashing to euro2. It is necessary to dismantle the rollers and their visual assessment. It is usually sufficient to weld the mesh inside the catalyst by spot welding in place so that the catalyst does not have a degree of freedom inside the metal housing.
If your catalysts really began to break down or melted, you can’t just reflash to EURO2 to clear the error. Deteriorating catalysts must be cut out or replaced, otherwise the destruction of the upper catalysts may begin and subsequently the cylinders may be filled with ceramic dust.
Are the problems of the Infiniti QX56 with the engine and catalysts so terrible? Definitely not. Cases of destruction of the coating of cylinders due to destroyed catalysts - less than 0.5%. The main reason for the destruction of the alusil coating of VK56VD cylinders is oil starvation and overheating. Therefore, we do not recommend proactively cutting or changing anything.

Infiniti Qx56 and Nissan Patrol do not like long exhausting off-road. Despite the presence of a frame and a lower gear, the razdatka of these cars overheats quite quickly during slippage. Be sure to check all off-road modes in a test drive. The absence of errors in the all-wheel drive system in this case does not mean anything.
What kind of suspension does the Infiniti QX56/QX80 have?
Understanding the vinaigrette of pneumatic and hydraulic suspension Z62
The Z62 platform has a very tricky hydropneumatic suspension. Let's start with the fact that pneuma is only on the Infiniti QX and is absent on the Nissan Patrol co-platform, it must also be emphasized that Infiniti pneuma is only on the rear axle.
Pneuma is inactive and serves only for the comfort of rear passengers and body level control. Cases of malfunction of pillows or the compressor are single. There is NO pneuma in front, and it is also impossible to increase or decrease the level of clearance manually.
The cost of the air suspension compressor for the Infiniti QX56 ranges from 25 to 50 thousand rubles, depending on the city and type of retail network. Rear axle air bellows run an average of 200 thousand km, but most often much longer. The reason for replacing them is usually the leakage of the fittings, as a result, the machine falls back during the night idle.
Infiniti QX56 / QX80 shock absorbers are not ordinary, but with hydraulic reservoirs connected to a common hydraulic circuit with pumps and two hydraulic accumulators. In fact, this system is an analogue of the ABC (Active Body Control) hydraulic suspension from Mercedes, with the only difference being that in Infiniti, the clearance is not regulated by pressure in the hydraulic struts, because. hydraulic struts are made a little differently.
The hydraulic suspension of the Z62 performs both the role of shock absorbers and stabilization of body rolls. In terms of changes in stiffness and clearance, the system is passive and does not have a range of changes / adjustments. The roll suppression mechanism, on the other hand, is also active when cornering, with a delay, but it tries to control roll and body roll. It is impossible to change the rigidity of the system, the system is not controlled by the driver.
Despite the technical complexity of the hydraulic suspension, Infiniti has practically no problems with the integrity of the hydraulic circuit, accumulators or pumps.
What is the difference between QX56 and QX80?
What is the difference between Infiniti QX56 and Nissan Patrol?
The main difference in technology lies in the different brake mechanisms and the different diameters of the brake and wheel discs.
The QX56 has floating calipers for a larger brake disc diameter than the Patrol, which has the stock Akebono brakes found on the FX37 and other cars.
Wheel disks on Infiniti QX56/QX80 were regularly installed only by R22.
The Nissan Patrol does not have rear passive air, but the hydraulic suspension is exactly the same.

Model Infiniti QX80 (formerly known as QX56) is presented in an updated version. Instead of a generational change, this is the second restyling for an SUV that has been produced in the current body since 2010. The updated QX80 is assembled in Japan and at the end of 2017 appeared in the markets of the USA, the Middle East and Asia. Changes in the exterior refreshed the appearance of the model.
The front end is completely new and more aggressive: a larger grille; new, higher raised headlights; the hood has become wider; the front bumper received an even larger air intake and new LED “foglights” with an elegant slim shape. The chrome frame of the radiator grille and air intake has changed, the air intakes on the wings have received a different shape. The rear part has also been modernized - there are new lights, a bumper, a chrome trim. The design of the huge 22-inch rims that the QX80 flaunts as standard has changed. On the Russian market, the new version is offered with the same petrol 5.6 V8 (405 hp) and a 7-speed automatic transmission.
Changes in the interior of the 2018 Infiniti QX80 are minimal. This is a new seat upholstery (with diamond stitching) and door trim, improved materials and sound insulation. In the standard Luxe version, the car is equipped with LED adaptive headlights, a new InTouch navigation system with traffic information, and a voice command function in Russian has been added. The interior of the car is trimmed with genuine leather, the driver's seat is equipped with electric adjustment in ten directions. Second-row passengers are offered the Infiniti infotainment center, with color displays integrated into the front seat headrests, the size of which has increased from 7 to 8 inches. The Luxe ProActive version received an enhanced security package, as well as a premium 15-speaker Bose Cabin Surround 5.1 audio installation. The main novelty in the Luxe ProActive package is the Smart Rearview Mirror, which allows the driver to use it as a regular mirror or turn it into a video monitor on which the image from the rear video camera is projected.
The upgraded QX80 is offered in both trim levels with Nissan's VK56VD 5.6-litre V8 petrol (405 hp), 7-speed automatic transmission and all-wheel drive. The engine is distinguished by direct fuel injection, a variable valve timing system on all camshafts, as well as a VVEL valve lift system and complies with Euro-5 requirements. In the urban cycle, the QX80 is content with 20.6 liters of gasoline per 100 km and 11 liters outside the city; in the combined cycle, fuel consumption is 14.5 l / 100 km. The volume of the fuel tank is 100 liters.
The Infiniti QX80 has an independent spring double wishbone suspension at the front and an independent, air-operated double wishbone at the rear. Pneumatic rear suspension elements maintain a constant ground clearance. According to the manufacturer, the updated QX80 received new shock absorbers with a 30% reduction in damping force for a smoother ride and to reduce vibrations on rough surfaces. The All-Mode 4WD drive system is able to calculate the required tractive effort in real time and respond instantly to changing conditions. In AUTO mode, it automatically distributes torque between the front and rear wheels for better handling and dynamic acceleration. In addition, 2WD, 4WD High and 4WD Low modes are provided. Overall dimensions are impressive: body length - 5340 mm, width - 2030 mm, height - 1925 mm. The wheelbase is 3075 mm, and 12.6 m is required for a turn. The luggage compartment has a volume of 470 liters, which, after the transformation of the cabin, increase to 2693 liters.
As standard, the 2018 Infiniti QX80 is equipped with a surround view system, an approaching object detection system, and a parking management function. The Luxe ProActive version received an expanded package of Infiniti Drive Assist safety systems, including adaptive cruise control, a lane departure warning system, a blind spot monitoring function, a collision avoidance system when reversing and other equipment.
The Infiniti QX80 is a typical American car, created by Japanese engineers, and at the same time perfectly suitable for Russian conditions. The downsides are usually lack of visibility, large overhangs and low-profile R22 wheels, more suitable for the highway. Before, even despite the perfectly balanced driving performance, the QX80 chassis was noticeably stiff on the country road. But with suspension tweaks, comfort should improve. On the plus side, experts note excellent dynamics, convenient controls, large capacity, as well as the presence of one of the most powerful V8 engines in the class. From the point of view of comfort, the best choice would be a seven-seat configuration with second-row captain's chairs.
The Infiniti QX80 is an all-wheel drive luxury SUV in the full-size segment, which is the "indisputable flagship" in the model range of the Japanese automaker, which combines an impressive appearance, luxurious interior, rich equipment and good off-road potential ...
Its main target audience is family men with a high level of income who do not need anything, but through the “iron horse” they want to demonstrate their “high social status” ...
The premium SUV Infiniti QX80 was born in 2013 - by renaming the QX56 model during the total rebranding of the Japanese brand's lineup, inheriting from its predecessor both the design and the technical component without any major improvements ... However, in the spring of 2014, the public debut ( on the catwalks of the New York Auto Show) celebrated a modernized version of the car, however, the update was limited to only “little blood” - the five-door slightly corrected its appearance, added new exterior colors and trim colors and expanded the list of available equipment, but did not highlight any technology improvements.
In November 2017, the Japanese "giant" experienced the second restyling in his life - he appeared before the general public as part of the international motor show in Dubai. And once again, the metamorphoses affected mainly the exterior - the front of the SUV was seriously redrawn, giving it a resemblance to other models of the brand, and slightly tweaked the stern. True, the changes were not limited to these only - the car received a new seat upholstery with a diamond-shaped stitching and door trim, as well as an improved multimedia complex.
With all its appearance, the Infiniti QX80 inspires respect and awe, even when standing still, and looks brutal and very pretty, and thanks to the smooth curves of corners and surfaces, it is also impressive and moderately harmonious.
On the presentable facade of the SUV, small LED “sabers” of optics are adjacent to a huge chrome-plated “shield” of the radiator grille, and its monumental stern flaunts a large trunk lid and graceful lights.
And from the side, the car impresses with its scope, emphasizing its majesty with “muscular” sidewalls and wheel arches of impressive size.
The overall dimensions of the Infiniti QX80 are truly gigantic: the length of the car is 5340 mm, height - 1925 mm, width - 2030 mm. Between the pairs of wheels, the "Japanese" found a place for a 3075 mm base, and under the "belly" a ground clearance of 234 mm is visible.
The interior of the Japanese "giant" looks attractive and moderately presentable, although somewhat rustic compared to many competitors, but it is distinguished by careful thoughtfulness and the highest quality of workmanship.
There is nothing inappropriate or shocking on the front panel of the SUV, everything is extremely clear and very ergonomic. The instrument cluster is beautiful and informative, the large steering wheel is comfortable and multifunctional, and the solid center console is logically divided into three “thematic floors”: the first is in charge of the “climate”, the second is in charge of “music”, and the third has an 8-inch infotainment screen. systems.
The decoration is finished exclusively with "thoroughbred" finishing materials - expensive plastics, high-quality leather and natural wood.
By default, the Infiniti QX80 has a seven-seat interior. Puffy front seats look good, but are not very comfortable in practice due to the short cushion and weak lateral support.
The rear row of seats, which provides passengers with royal space, is divided in the middle by a massive pedestal, and can optionally be replaced by a full-fledged sofa. A triple "gallery" is more suitable for only two riders, but it does not suffer from a lack of space.
Even when fully loaded with passengers, the Infiniti QX80 still has a 470-liter compartment to accommodate luggage. The seats of the second and third rows are electrically folded into a completely flat area: in the first case, the volume increases to 1400 liters, and in the second - up to 2690 liters. The spare wheel of the car is attached under the bottom.
Powered by a powerful VK56VD gasoline engine, the Japanese SUV is a 5.6-liter (5552 cubic centimeter) aluminum V-shaped "eight" with direct injection, a 32-valve timing, two overhead camshafts driven by a chain, and a VVEL system that changes the height of the lift valves.
The engine, which meets the environmental requirements of Euro-4, peaks at 405 "horses" at 5800 rpm and 560 Nm of torque at 4000 rpm, and is equipped with a 7-speed "automatic" with "manual" mode and driving wheels of both axes.
All-wheel drive transmission All Mode 4 × 4 on the Infiniti QX80 is equipped with an electromagnetic clutch in the drive of the front axles and “flaunts” three modes of operation:
- Auto - as the rear wheels slip, up to 50% of the moment is directed to the front;
- 4H - thrust is divided between the axles in equal shares (the clutch is rigidly locked);
- 4L - Downshift started.
But with off-road capabilities, due to its solid size, this “Japanese” is not doing well: the angles of entry, exit and ramp are 20.9, 22.3 and 20.7 degrees, respectively.
But in road disciplines, the car shows excellent results: this “giant” rushes to a maximum of 210 km / h, and “shoots” from a standstill to 100 km / h in 7.5 seconds.
In the combined driving mode, the five-door consumes 14.5 liters of fuel per "hundred" (20.6 liters are "destroyed" in the city and 11 liters on the highway).
The basis for the Infiniti QX80 is a platform from Nissan Patrol with a frame integrated into the power frame of the body and having programmed deformation zones front and rear, and a longitudinally oriented engine.
The off-roader's suspensions are independent on both axles: "double-lever" in the front and "multi-link" in the rear. By default, the car is equipped with anti-roll technology HBMC, which eliminates body roll and roll due to the closing hydraulic locks of the front and rear stabilizers under lateral loads.
“In a circle” the five-door demonstrates ventilated brake discs with a diameter of 350 mm, working in conjunction with a large number of modern “gadgets” (ABS, EBD, BAS, etc.).
The hydraulic control booster is standardly integrated into the steering complex of the "Japanese".
In the Russian market, the 2018 Infiniti QX80 is offered in two trim levels - Luxe and Luxe ProActive. The first equipment option with a seven-seat interior costs at least 4,855,000 rubles, and the second - 5,185,000 rubles (the surcharge for eight-seat decoration in both cases is 15,000 rubles).
- The initial version boasts: eight airbags, 22-inch wheels, adaptive LED headlights, a multimedia system, an audio system with 13 speakers, all-round cameras, an automatic parking system, heating, ventilation and power front seats, heated second row seats, power trunk lids, leather trim, ABS, TSC, VDC, three-zone "climate", keyless entry system and a bunch of other equipment.
- The more expensive version additionally has: adaptive cruise control, a rear-view mirror with a built-in display, a lane marking tracking system, blind spot monitoring, collision avoidance technology, and some other “bells and whistles”.
The Infiniti QX4 SUV, aimed at the American market, was put into mass production in 1996. In fact, it was a second-generation model, distinguished by its external design and richer equipment.
The Infiniti QX4 was a real rogue with high ground clearance, low gearing and differential locks. The car was powered by a V6 3.3 petrol engine (168 hp), in 2001 the engine was replaced with a more powerful 3.5-liter, developing 240 forces. The transmission was automatic, four-speed.
The QX4 model was produced until 2003 in Japan, in the local market it was known as.
2nd generation (JA60), 2004–2010
The Infiniti QX56 SUV, which debuted in 2004, moved to the assembly line of Nissan's American plant in Mississippi. The car was sold in the USA, Canada, some countries of the Middle East, and in 2007 its official deliveries to Russia began.
The frame Infiniti QX56 was created on the F-Alpha platform, common with a pickup truck, and the general design of its body was the same as that of an SUV. Under the hood was a 5.6-liter V8 petrol engine with a capacity of 315-325 hp. with., working in tandem with a five-speed "automatic".
On the Russian market, only SUVs with all-wheel drive and a reduction gear were offered at a price of 2.5 million rubles. American buyers could also purchase a rear-wheel drive Infiniti.
The release of the model continued until 2010.

3rd generation (Z62), 2010–2013
The next generation of the Infiniti QX56 SUV was introduced in 2010, the production of cars was transferred from the USA to Japan. The car retained the frame structure, but became even larger. This time, its counterpart was the Y62 series model.
The Infiniti QX56 received an all-new 5.6-liter direct-injection eight-cylinder engine that produced 405 hp. With. The transmission was automatic, seven-speed. The design feature of the chassis is the absence of anti-roll bars, their functions are performed by active hydraulic cylinders built into the shock absorbers.
As before, the SUV had versions with rear or all-wheel drive, but only all-wheel drive cars were delivered to Russia. The interior of the car could have seven or eight seats.
The list of markets where the Infiniti QX56 was offered has expanded: USA, Canada, Mexico, China, South Korea, Malaysia, Vietnam, Russia, Ukraine, Azerbaijan. In our market, an SUV could be purchased at a price of about 3.3 million rubles. In 2012, SKD assembly of cars for Russia began at the Nissan plant in St. Petersburg.
In 2013, the model was renamed in due to a change in the brand index system.
