Infiniti Qx56 problems
The Infiniti QX80 (formerly called the Infiniti QX56 until 2013) is a full-size luxury SUV marketed by Nissan's luxury division Infiniti. The first-generation QX56 was built in the United States and is based on the first-generation Armada. The second-generation model was released in 2010 as a model produced in Japan, which used the sixth-generation Patrol (later also marketed as the second-generation Armada since 2016) as the base vehicle instead. Since the 2014 model year in 2013, the vehicle was renamed to the QX80 as Infiniti renamed their entire product line under a new nomenclature.
First generation (JA60; 2004)
The first-generation QX56 (model code JA60) is based on the first-generation Armada, while also sharing the F-Alpha platform with the first-generation Titan. It is the first Infiniti built in the United States. The QX56 was only marketed in the United States, Canada, Russia, Oman, Bahrain, Qatar, UAE, Kuwait and Saudi Arabia. Development on the JA60 QX56 began in early 2000 alongside the WA60 Armada. A final design by Masato Takahashi was reached in early 2001, with an August 2001 design freeze for early 2004 start of production.
The rear door handles were installed on the C-pillar as a Nissan design tradition started with the D21 Pathfinder released in 1985 to visually make it appear like a two-door truck with a camper shell, with conventional door handles on the front doors.
The first-generation QX56 was powered by a 5.6-liter VK56DE V8 engine (320 hp (239 kW) at 4,900 rpm and 393 lb⋅ft (533 N⋅m) torque at 3,600 rpm) and a 5-speed automatic transmission with an overdrive. As is common with aluminum blocks, each cylinder in the engine was lined with cast iron. The valvetrain was a DOHC design with four valves per cylinder. Infiniti designed the QX56's throttle responsiveness to correspond to specific drivetrain modes: when the driver selects all-wheel drive, the throttle becomes less sensitive, presumably to allow easier regulation of acceleration when off-road.
The QX56 had around 9,000 lb (4,082 kg) of towing capacity. Mileage at peak performance drain is 12 miles per US gallon (20 L/100 km; 14 mpg‑imp). It comes in one trim level, with only key options such as: DVD entertainment system, 4WD/2WD, and a bench instead of captain chairs as the second row. Other features which came standard were a ten-speaker Bose system, DVD-based navigation system, leather trim for all seats, dual-climate control, 18-inch chrome alloy wheels, and an adaptive cruise control system. A Precrash system was a unique feature in the market as well.
Since the demise of the Q45 (which was priced above the QX56) after 2006, the QX56 was the most expensive Infiniti sold in North America and was Infiniti's only full-size vehicle.
In early 2007 for the 2008 model year, the Infiniti QX56 received a minor facelift which included a revised grille, a redesigned interior, a new intelligent key system, more standard equipment, new third-row seats that fold electronically and standard 20-inch chrome wheels. Introduced at the 2007 North American International Auto Show in January 2007, the facelifted model went on sale in April 2007.
After the 2010 model year, the QX56 and Armada no longer share the same body, as the first-generation Armada continued to be produced in the United States until the 2015 model year, while the second-generation QX56 switched to the body used by the Y62 Patrol.

- Date Complaint: 2024-08-05
- VIN: JN8AZ2NE0B9
- Components: SUSPENSION
- Summary: A subframe is a key structural component of every car. As such, it stands to reason that it should last as long as the car itself. Doing much research on this model suspension and subframes become rusted as I didn’t know this when purchasing making it very unsafe . I experienced being involved in almost 2 accidents. Very dangerous. Subframe split in half and suspension. Something needs to be done as a lot of people are going thru this issue and Infiniti slogan claims “new horizons” by no means new horizon going to heaven by driving their vehicles.

Vehicle year: 2006
After one month, we haven't encountered any issues. We find it to be a significant upgrade from our previous suburban. The car has great power, solid suspension, and firm brakes. When driving around town, we remove the second-row center console so that the kids can easily access the third row without having to flip seats. This is especially convenient when there are car seats or boosters in the second row. However, we have experienced some difficulties with the telematics. The Bluetooth implementation is simplistic and the voice recognition is poor. Additionally, we find the navigation system to be frustratingly limited when driving. It would be much more convenient if the front seat passenger could enter commands. Overall, we are very happy with the car and it has exceeded our expectations.

I am so glad to hear that you are impressed with the vehicle! The interior room and quality of materials are truly excellent, and the towing capacity is very impressive. I also agree that the exterior is very impressive. It's great to hear that you've had positive experiences with Infiniti, and I'm happy to hear that your family now owns two Infinitis - a QX56 and a FX35.

Vehicle year: 2004
This car is fantastic! It drives smoothly and quietly on the freeway, and I love the aggressive body design. At 17.25 feet long, it definitely turns heads. And the spacious interior is like being in a limo, with more leg room than you would expect. Even us big guys (I'm 6'6) find the third row to be comfortable, which was not the case with my previous GMC Denali. Plus, the navigation system is incredibly user-friendly, even for someone like me who doesn't use it often.

Vehicle year: 2008
This is my second QX56, the first being a 2005. I cannot stress enough how great this vehicle is. Neither of my trucks has ever had an issue. The dealership provides free oil changes every 3,500 miles and is a pleasure to deal with. The QX56 has just about everything a large, luxury SUV should have. It is so quiet, so powerful, yet nimble given its size.

Vehicle year: 2008
I had a 2002 Lincoln which was okay, but it had lower quality Ford plastic parts and some problems. However, I wasn't looking for a new car until I saw this one for sale in November 2016 with 117K miles on it. It had all the options I wanted except for the unnecessary 4-wheel drive. I was shocked at how nice of a car it was! It's a combination of a muscle car, SUV, and truck, with 400 ft lb of torque that burns rubber and can go from 0-60 in 7 seconds. The exhaust growl is like that of a muscle car! The seat is as comfortable as my old Caddy Eldo seats, but even better with heating. The back seats are also heated and can recline! The BOSE stereo system with CD recorder built in is amazing. I have the full optional entertainment package ($3000 when new) which is fantastic. There are so many options and gadgets that I still haven't figured out how to use after owning it for 16 months. The 2008 model looks nicer than previous years with extra chrome everywhere and a much nicer interior, as nice as a Mercedes S600 I once owned. It's the best looking SUV on the road, with a buffed muscular look to it and an exhaust growl to match. However, it does have some blind spots that one must learn to watch, especially at night with tinted windows. There were just a few minor repair issues that come with buying a 9-year-old SUV with 117K miles on it. It sits high, goes like a muscle car, carries 8 passengers or lots of stuff, and I love the power reclining rear seats. Keyless is nice. The navigation system needs to be updated by the dealer every few years, which I have not done. Parts are expensive like all others, and it is a luxury car with lots to go wrong when so heavily optioned. Gas mileage is bad, but that's why it moves like a muscle car, which I like. I did expect to get better than 12.9mpg on a road trip to Phoenix from San Diego, so I was a little disappointed in that (3 total people and luggage only). However, I did not buy it for mpg, but instead for everything else. It's a great vehicle, and I plan to keep it long term. I even think it looks better than the 2011 redesign (not as macho looking!).
Are you having problems with your Infiniti Qx56?
Orlo Gibson 2025-11-15
Vehicle year: 2011
If you are considering a 2011 and up Infiniti QX56, please be aware of our experience with this car. We purchased it to accommodate our large family and were initially drawn to its reliability and Japanese make. However, we have encountered numerous issues since day one. These include a mildew smell from the A/C Evaporator, a fan clutch replacement, a rusted windshield frame, and multiple visits to the dealer for a 'check engine light on' issue. We also had to replace the catalytic converter and timing chain, which were costly repairs. Unfortunately, Nissan (Infiniti) did not provide much assistance, especially since we were out of warranty. We are not alone in experiencing these problems, as many other QX56 and QX80 owners have reported similar issues. We urge you to research the service bulletin EM-002a and reference ITB13-009a from September 4, 2013, which addresses a whine noise from the engine area. Despite these challenges, we hope this information helps you make an informed decision about your car purchase.I had several visits to the dealer to inquire about the 'check engine light on' issue. The catalytic converter was replaced at 78,000 miles for $1,850.00 and the timing chain was replaced at 79,500 miles for $6,000.00. According to http://repairpal.com/abnormal-noise-from-timing-chain-area-266, this seems to be a common issue. However, I felt like the dealer was only interested in taking my money and not being transparent about the issues with my car. I even contacted Infiniti USA and spoke to Wendy, the regional manager for FL, but unfortunately, she was unable to offer any assistance at this time. Overall, this experience has left me feeling frustrated and disappointed. As a result, I have decided not to purchase any Nissan products in the future.
Lowell O'Hara 2025-11-11

Although I regret my experience with the QX56, I am confident in my decision to sell it. During the 10 months I owned it, the car had persistent rattling issues, including with the front end and overhead console, which had to be replaced. Despite selling it at a loss, I am relieved to have moved on from this SUV. In hindsight, I wish I had read reviews before purchasing it, especially since I traded in my Lexus LX470 for it in search of more space.
Jermey Satterfield 2025-11-04

The car has some areas that require attention, such as the door handles that may break in cold weather, low mileage per gallon, and windows that are hard to use. Additionally, the tires do not retain air and the car has poor handling. However, the car's navigation system is exceptional.
Julian Anderson 2025-11-02

This car has the potential to be great, but unfortunately, it has some issues that need to be addressed. Despite paying $55k for a luxury auto, there are rattles, shakes, and bad brakes that detract from the overall experience. While I had hoped these issues would have been resolved by 2005, I find myself in the same boat as the 2004 owners. It has taken a lot of time and energy to get Infiniti to make the necessary fixes, and unfortunately, the car is still not up to par. While it may look good on the outside, I am hesitant to have friends, coworkers, or clients ride in it due to these issues. If you are considering purchasing this vehicle, I would advise waiting a few years and reevaluating your decision or considering purchasing a cheaper 2004 model.

This car has had several issues that have surfaced years after my purchase. I am disappointed with Infiniti's lack of ownership and failure to address these problems. I will not be purchasing another Infiniti in the future. The worst issues I have experienced in my 3 years of ownership include the timing chain, ECM, catalytic converter, and defective paint. The dealership replaced the ECM three times in 2018, and I will be returning in January 2019 for the same issue. The roof and hood had to be painted after bare spots began to appear. Although compressed air on a spot the size of a nickel on my hood peeled the entire hood off, I am confident that Infiniti will take the necessary steps to address these issues. While there have been thousands of complaints, I believe that Infiniti will do what is right for the consumer.
