2021 Infiniti Qx80 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.

I've owned the 2011 original model and recently upgraded to the 2020 facelifted model. While it may not be as high-tech as the Audi Q7, it's still spacious, comfortable, and reliable - which is exactly what I need.

Hi there! I hope you're doing well. I wanted to share my experience with my 2011 QX56 (Vin 1499) and my 2016 QX80. This is actually my second QX since the updated body. I had some trouble with the timing chain tensioners and oiling issues in the first 1500 of these models, which caused my 2011 QX56 to rattle at about 83000 miles. However, Infiniti was amazing and offered me a great trade-in deal for my 2016 QX80. Both of my cars have been mechanically flawless, and I've only needed to change the tires every 36000 miles and the brakes (which are really good, by the way) at about 60000 miles. They're huge, quiet, and comfortable, with plenty of room for anything you need to carry. However, they do consume a lot of fuel, averaging about 9 mpg in the city, but I've gotten as much as 23 mpg on long trips. They're not sports cars, so they lean in turns and are heavy, but the 400hp is just enough. The only thing I didn't like about them is the transmission. The shift points are just all wrong, and it downshifts itself on the highway with the cruise on, which can be a bit crazy. For the price, I'd like to see them do better with the leather coloring, as mine in sand or wheat wore off of the steering wheel fairly early in its life. The gold piping on the seats also comes off pretty quickly, but it's not noticeable unless you really look at it and know what you're looking for. While the paint seems to look pretty good, it is fairly soft, and water spots are deep and take some serious detailing to remove on the black paint. Depreciation is pretty rough on these, but overall, I've had a great experience with my Infiniti cars. Have a great day! $90k sticker and 3.5 years later its only worth about $32k. Not great in my book. It had been updated significantly since 2016 though. I personally don't like the look of the new ones.

One month into owning the Infiniti, I have encountered no issues except for my gas mileage. Although the tank seems smaller and requires more frequent fill-ups than my previous MB GL450, the visibility is superior and there are no complaints about the cabin space. All of the controls are extremely user-friendly and easy to navigate. I am confident that this car will prove to be reliable for years to come.

This is my fifth INFINITI product, and I have had many of their smaller cars and SUVs in the past, and I have always been very happy with them. I decided to get something bigger for family use so that we could travel comfortably. The ride quality and interior are excellent, and the safety systems work great! Reliability is what keeps me coming back to the brand, as all of my INFINITI products have been flawless! This is a very comfortable long-distance cruiser, and the rear seat entertainment is easy to use. The heated/cooled seats work quickly, and the leather quality is good and resistant to discoloration (I have the wheat-colored quilted leather). Overall, the only downside is that the technology is badly outdated, but it still does the basics. Gas mileage is predictable for a large naturally aspirated V8, and the sound it makes is great with strong, smooth acceleration! Overall, I would buy again as this is an excellent luxury family do-everything proper (truck-based) SUV!

These vehicles ride smoothly and handle the road nicely.

Are you having problems with your 2021 Infiniti Qx80?
Ahmed Barton 2025-06-13
We've had this vehicle for about 5 months now and due to Covid, we've only driven about 5000 miles. We've noticed an issue with the cruise control, which has also been described by others here. When cruising at around 70 mph, the engine is running smoothly at under 2000RPM. However, when there's a slight incline in the road, the gearbox kicks down two gears and the engine revs up to over 5000RPM! It's a bit odd and disconcerting, and the mechanic at the dealer felt the same way. However, Infiniti has issued a directive stating that this is a normal operating characteristic of the vehicle that has been reported in multiple cases, so no further diagnosis should be performed. Other than that, it's a great truck if you can live with the size and fuel economy. The only other issue we've noticed is that the fuel gauge will indicate empty, but when you fill up, it only takes 20 gallons. The spec sheet says the size of the fuel tank is 26, so it signals empty with 6 gallons left in the tank.

I've had this vehicle for about 11,000 miles, 5,200 of which were on a road trip. The motor is strong and the transmission is smooth, making for a great performance. However, the handling can be a bit tricky as it feels top-heavy and can be unpredictable when cornering. The ride quality is generally smooth, but can be a bit scary on rough roads. The interior is very nice and comfortable, although the HVAC control can be a bit finicky. The electronics can be hit or miss, with the infotainment system being adequate at best. The storage is great, but the sloped back can make things fall out on long road trips. The third-row seats are slow to open and close, but can be great if you have the time. As for gas mileage, it's not the most efficient vehicle out there, but it's not the main reason for purchasing it. Overall, it's a comfortable and reliable vehicle that can handle long road trips with ease.If you're looking for a powerful vehicle with great torque, this could be the one for you. However, keep in mind that it can be expensive to fill up the tank. Additionally, if you plan on driving in snowy conditions, it's important to invest in good winter tires. The factory all-season tires may not be sufficient. I had the chance to drive this vehicle in several heavy snowstorms here in CO and it wasn't my top choice. In fact, I ended up trading it in less than 7 months later. Considering the price tag of 80k, you would expect to feel safe and blown away, but unfortunately, that wasn't my experience with this vehicle.

I bought this SUV in December 2019, used with only 1200 miles on it. According to the seller, the previous owner was a nurse who had to park in a parking garage every day, which is why she sold it. However, I'm starting to wonder if she just didn't like it as much as I do. I agree with other reviews that the cruise control is concerning. On the slightest incline, the RPMs rev and stay up until the incline has passed, causing the car to jerk and the engine to be extremely loud. The backup camera at night is also terrible! I can't see anything out of it. Of course, the Infiniti shop says it's normal. The technology in this car is not user-friendly. My previous car was a Honda Odyssey, and I found its front panel easy to navigate and intuitive. Nothing about this Infiniti's control panel makes sense to me. I've had the car for over a year now and still haven't figured it all out. Then there are the little things that drive me crazy daily. The front cupholders are too big, which is a huge design flaw. Every time I accelerate, the cups fly forward, and I have to hold them as I pull out into traffic. I've asked Infiniti if they sell inserts, but they don't. They did say that this is a common complaint. I don't understand how the second-row cupholders have adjustable cupholders, but not the front! The third-row seats are on a switch, and they're SO SLOW to fold down or bring up. I also don't like that they don't fold flat. Lastly, the second-row seats don't move, which I didn't notice when shopping for the car. The second row is so roomy for your passengers, but if you have to put adults in the third row, they have to sit with their knees sideways. To me, that's another huge design flaw.

I had the pleasure of driving the QX80 for a weekend as a rental, and I must say, it was a very comfortable ride. The interior is luxurious and the car is well-designed. However, I did notice that the car is based on a 10-year-old platform, which may make it feel a bit outdated. Additionally, I was surprised to find that some features were missing, such as air-conditioned seats, heated rear seats, an entertainment system, and a standard audio system. While these may seem like small details, they are important to consider when purchasing a car in this price range. Overall, I think the QX80 is a great car, but there are some areas where it could be improved. If you're looking for a more affordable option, the Armada may be a better choice for you.
Rashad Kessler 2025-03-01
I have been enjoying my QX80 for three years now, but recently the sensors have been buzzing for no apparent reason. Although the car is still under warranty, Infiniti has declined to cover the cost of replacing the three sensors that have paint chipping due to normal wear and tear from driving, which is causing the sensors to go off. The cost to replace all three sensors is $1500. It is surprising that the sensors on the front bumper of a three-year-old car cannot withstand normal abrasion from driving. I have never had issues with sensors from other manufacturers, and I am disappointed that this is happening now.
