2020 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.

Common 2020 Infiniti Qx80 problems
The Infiniti QX80, a luxurious and spacious SUV, has been reported to have several common problems by its owners. While the QX80 offers a perfect blend of elegance, performance, and advanced features, it is not immune to occasional issues. Here are some of the most frequently reported problems with the Infiniti QX80, based on owner complaints and available search results:
- Transmission Problems: Transmission issues are one of the most commonly reported problems with the Infiniti QX80. Some owners have faced problems such as rough shifting, delayed engagement, and in severe cases, complete transmission failure. These transmission issues can be caused by various factors, including a faulty transmission control module, worn-out internal components, or electronic glitches. Regular maintenance, including fluid changes and inspections, is essential to prevent or detect transmission problems early. Timely diagnosis and repairs by experienced technicians can help keep the QX80’s transmission in optimal condition and ensure a smooth driving experience.
- Starting Problems: Starting problems have been a concern for some Infiniti QX80 owners. Drivers have encountered difficulties starting their vehicles, experiencing issues like the engine not cranking, slow cranking, or intermittent starting problems. These starting issues can often be traced back to components such as a weak battery, faulty starter motor, or a defective ignition switch. Regular maintenance of the battery and charging system can help prevent starting problems. Should any starting issues arise, seeking professional diagnosis and repair is recommended to prevent being stranded unexpectedly.
- Starter Problems: Starter-related problems are closely linked to the starting issues experienced by some QX80 owners. The starter is a crucial component responsible for engaging the engine when the ignition is turned. Signs of a faulty starter may include clicking noises when turning the key, no response from the engine, or intermittent starting problems. Ignoring starter issues can lead to complete vehicle breakdowns. If you suspect any problems with the starter, it is advisable to have the starter system inspected by a qualified technician and replaced if necessary, thus ensuring reliable vehicle operation.
- Suspension and Ride Quality Concerns: Some Infiniti QX80 owners have reported issues related to the vehicle’s suspension and ride quality. These concerns can manifest as a rough ride, uncomfortable handling, or excessive noise while driving. Suspension issues can be caused by worn-out components, improper alignment, or other mechanical problems. Regular suspension inspections and timely repairs can help maintain the QX80’s ride quality and ensure a comfortable driving experience.
- Infotainment System Glitches: Some owners have reported issues with the infotainment system, such as freezing screens, Bluetooth connectivity problems, or unresponsive touchscreens. These glitches are typically software-related and can often be resolved through software updates and patches released by the manufacturer. It is essential to keep the infotainment system up-to-date, and if necessary, visit an authorized Infiniti service center for any required software fixes.
- Battery Issues: The 2014 Infiniti QX80, in particular, has been reported to have battery issues, where the battery struggles to hold a charge. This issue can lead to symptoms like the car not starting at all. While this issue seems to be rare, it is essential to ensure the battery is in good condition and can handle the vehicle’s electronic features.
- Timing Chain Problems: The 2014 Infiniti QX80 has been reported to have timing chain problems, where the timing chain can become stretched and eventually fail. This issue can lead to expensive repairs, as the timing chain typically needs to be replaced. While this issue seems to be specific to the 2014 model, it is essential to be aware of this potential problem when considering a used QX80 from this model year.
By understanding these common problems with the Infiniti QX80 and implementing proper maintenance and timely repairs, QX80 owners can enjoy a smooth and trouble-free driving experience.

SERVICE BRAKES,FORWARD COLLISION AVOIDANCE PROBLEM
- Date Of Incident: 2024-04-09
- VIN: JN8AZ2NF9L9
- Components: SERVICE BRAKES,FORWARD COLLISION AVOIDANCE
- Summary: The brakes automatically engage without cause. The problem occurs at both city and highway speeds, from 20-75 mph. It is particularly bad when passing underneath a bridge. The car will abruptly stop. This has been ongoing for monthes. Sometimes, the vehicle will act inappropriately when the brake is applied by the driver. The car will attempt to accelerate. Other times the car will hard brake as if slamming the brakes.
UNKNOWN OR OTHER,VISIBILITY/WIPER,BACK OVER PREVENTION PROBLEM
- Date Of Incident: 2023-07-24
- VIN: JN8AZ2NE9L9
- Components: UNKNOWN OR OTHER,VISIBILITY/WIPER,BACK OVER PREVENTION
- Summary: While waiting in a parking lot, I was reviewing the settings available on the lower center display, one of those options was for "Camera." Inside this menu I found and made adjustment for options like brightness, contrast, tint, color, and black level... and while most of those seemed to work well, and I was able to make suitable adjustments to the camera--the tint and color options seemed to have no effect on the image. So, I opted to adjust tint from the default/middle value all the way to the left/lowest value and save the settings. Even then, with that saved, I was able to switch to the camera and could see there was no difference in the image still. I then remained with the vehicle, still parked with the engine idling, waiting another ten minutes or so before preparing to leave. When I put my vehicle in reverse gear, I was shocked to see that the camera displays had gone completely black. I could no longer see the rear images when backing up. I tried going back to park and again to the rear setting--still, there was no image being displayed for the cameras. I could see some items on-screen still, like the button to switch camera views and to toggle the parking sensors on/off. When switching camera views/angles, the system would continue displaying the same two black/empty displays. I tried turning the engine off and back on--but that didn't seem to have any effect, the system remained broken. I was able to use the rear view camera on the reviewer mirror--but the normal backup cameras remained non-functioning. I promptly tried opening the camera settings again to reset all of the brightness, contrast, tone, color, and black level settings to the default values... but still, the preview area was black and no image could seen. I've verified the outside of the vehicle... these cameras are not blocked at all. There was nothing that could've cause these to go dark. I drive the vehicle home (~5 miles), and found the camera still not to be working.
FORWARD COLLISION AVOIDANCE PROBLEM
- Date Of Incident: 2022-05-01
- VIN: JN8AZ2NE7L9
- Components: FORWARD COLLISION AVOIDANCE
- Summary: Vehicle aggressively and without cause engaged the Automatic Emergency Braking System causing the driver to be slammed against her seat belt and almost having the car in back of us to almost rear end our vehicle. This has happened in the past but it has been a manageable slight deceleration when going around a gentle curve or at the railroad overpass. . This time the incident was intense almost causing a rear end collision. I would add that this severe incident happened when approaching the same railroad overpass in the rain. This has also happened at this intersection in good weather. Under all circumstances there were no obstructions I front of the vehicle. I have read that this problem has occurred in earlier years of Nissan products. In all instances the appropriate system warning light illuminated.
FUEL SYSTEM, GASOLINE PROBLEM
- Date Of Incident: 2021-07-02
- VIN: jn8az2nf1l9
- Components: FUEL SYSTEM, GASOLINE
- Summary: The contact owns a 2020 Infiniti QX80. The contact received notification of NHTSA Campaign Number: 21V373000 (Fuel System, Gasoline) however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The local dealer and the manufacturer were made aware of the issue. The contact had experienced a failure where the vehicle would not start as needed. The contact related the failure to the recall. Parts distribution disconnect. The failure mileage was not available.
VEHICLE SPEED CONTROL PROBLEM
- Date Of Incident: 2020-03-02
- VIN: JN8AZ2NF6L9
- Components: VEHICLE SPEED CONTROL
- Summary: THE CRUISE CONTROL IS VERY ABRUPTED WHEN ENGAGING THE RESUME FEATURE. THE CRUISE WILL CAUSE THE TRANSMISSION TO DOWNSHIFT AND ENGINE TO REV ABOVE 5000 RPMS FOR JUST A COUPLE OF MPH SPEED INCREASE. I BELIEVE THIS A DESIGN FLAW THAT COULD CAUSE A DRIVER TO LOSE CONTROL OF THE CAR.

I absolutely love my 2019 QX80 Luxe! It is incredibly capable both around town and on the highway. While some may argue that it is not the best in its class, I personally cannot imagine anything running better or feeling more comfortable. I adore the fact that I am still driving a tank-like TRUCK, but with all the luxurious features that keep me in touch with the road below. Sure, the feel-good technology may not be the best, but who cares? The safety technology is just as good as the competition. I prefer to use my phone for directions anyway. Plus, the fact that I saved several thousand pounds compared to the competition when I bought mine still puts a smile on my face, despite the so-so feel-good technology. And let's not forget about the stunning looks and refined feel of the car - to me, it just feels perfect.

These vehicles ride smoothly and handle the road nicely.

The vehicle's cruise control functioned at 55 mph, but unfortunately only achieved 13 mpg on flat terrain. When encountering small hills, the car abruptly shifted to a lower gear, causing the engine to roar. Additionally, getting in and out of the vehicle was difficult and it drove and rode like a truck. The instrumentation was counter-intuitive and in need of a technology upgrade. Overall, I would not want to have to set the mirrors and seat in a dark rental lot.

Better than any other SUV!
-
I really appreciate every feature of the QX80!

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 to me, its front panel was easy to navigate and just made sense. Nothing about this Infiniti's control panel makes sense. 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 unfortunately, they do not. They did say that this is a common complaint. I don't understand how the 2nd row cupholders have adjustable cupholders and not the front! The 3rd row seats are on a switch, and they are SO SLOW to fold down or bring up. I also don't like that they don't fold flat. Lastly, the 2nd row seats don't move, which I didn't notice when shopping for the car. I wish I would have. The 2nd row is so roomy for your passengers, but if you have to put adults in the 3rd row, they have to sit with their knees sideways. To me, that's another huge design flaw.

I've owned three Nissan Armadas and really enjoyed them. My wife got an Infiniti 60 and was thrilled with it. I decided to upgrade to a slightly more luxurious model, but unfortunately, the 2018 Infiniti QX80 has had several issues. For instance, while driving down the road, a piece of windshield trim started flapping on the side of the car. When I contacted Infiniti, they responded that it might be under warranty, but I would need to drive it 1 1/2 hours to inspect and possibly order the trim, then bring it back to fix. The car is less than a year old, and they don't allow Nissan dealers to work on the vehicle. I understand that the distance issue is my problem, but I've had three issues and have given up on even considering a warranty repair. It's very disappointing, and I won't be buying Infiniti in the future. However, I will say that the Armadas were fantastic vehicles.

This luxury SUV has hard and uncomfortable seats. However, it is important to note that comfort preferences may vary from person to person. It is recommended to test the seats before making a purchase if comfort is a top priority for you.
Candido Wyman 2024-08-27
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.
Kirk Bashirian 2024-08-14
This SUV is quite large, but unfortunately, the front seat falls short in terms of legroom. As a tall female, I found that the lack of thigh support caused discomfort in my hips, knees, and back. Additionally, the lumbar support is positioned too low, which results in it cupping your back instead of supporting the lumbar arch. It's a pity that these issues detract from the otherwise smooth ride of the car. In hindsight, I wish we had opted for the Tahoe or Yukon instead.
