2018 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.

- VIN: JN8AZ2NF6J9
- Components: ELECTRICAL SYSTEM,EXTERIOR LIGHTING
- Summary: The dashboard bulbs went out from 0-40 mph and 6-8 rpms. It seems to be a common issue on Reddit and I have found complaints on the internet.

- VIN: JN8AZ2NCXJ9
- Components: ELECTRICAL SYSTEM
- Summary: Similar to other complaints, the instrument cluster lighting is beginning to go dim or completely out starting at the high end of the RPM gauge and the low end of the speedometer gauge. This is an issue during night time driving.
ELECTRICAL SYSTEM PROBLEM
- Date Of Incident: 2023-12-01
- VIN: JN8AZ2NF0J9
- Components: ELECTRICAL SYSTEM
- Summary: The primary instrument gauge for the QX80 starts to lose illumination from around the speedometer and tachometer. The vehicle has 55,000 miles and is a 2018 model. This is the SECOND time this has happened, with the instrument gauge being replaced first at approximately 32,000 miles for the same reason. Currently the instrument gauge is continuing to lose lighting - making the speedometer impossible to see at night (SAFETY ISSUE). Infiniti Dealership reports that there is a +/- 2 YEAR waitlist for replacement instrument clusters, and that this is a known problem. The same dealership that replaced it a few years ago. This 2nd instrument cluster started going out in the 20-45 mph segment, then 6500-8000 rpm tach, then 0-20 mph.
STEERING PROBLEM
- Date Of Incident: 2023-10-15
- VIN: JN8AZ2NE7J9
- Components: STEERING
- Summary: The plastic trim on the steering wheel that is colored to match the other plastic trim in the car has cracked at the 2:00 clock position. The cracked plastic sometimes lifts when turning the wheel which I feel may cause an accident. I have not had it inspected by the dealer of manufacturer as I'm aware they won't repair it currently. There were no symptoms before it happened, it was just cracked/separated one day. Nissan/Infiniti should be required to repair this potential safety issue.
UNKNOWN OR OTHER PROBLEM
- Date Of Incident: 2023-07-08

Told us that in an accident the bags would not deploy and repair is more than $5000! We contacted Nissan north America. Extremely rude employee said too bad as vehicle was out of warranty. Said "maybe" could have done something if we had serviced vehicle at dealer instead of private shop but too bad. Explained that mechanic at dealership said this is a common problem and he was surprised it is not a recall. She told me well it isn't so that is that. She refused to give me to her boss.

After the dealer made the major repairs my vehicle needed, I'm really pleased with it. I've had it for about a year now and so far it's been great. I'm planning to take it out on the highway this summer, so we'll see how it goes!

Awesome vehicle with all the bells and whistles you need in a Large SUV and more

Better than any other SUV!

The car is great overall! However, it seems that the Infinity QX80 does not hold its value very well. If you plan on selling your used QX80, you may expect to take a significant loss. For example, I bought mine a little over a year ago with a sticker price of 81K, and now, one year later, it's valued at 48K, which is a 30K+ drop in just one year. Despite this, I appreciate the experience and will consider other options in the future.

I would like to suggest considering a used vehicle with lower mileage. In our case, we were able to purchase the highest trim level, the Limited, which comes with exclusive features. By doing so, we saved over $55,000 compared to the retail cost of $90k. The ride, styling, and build quality are all excellent.

The front grill has a significant issue. However, I am confident that they will take the necessary steps to address the problem.
Brycen Williamson 2024-06-29
After driving our vehicle for 2 years and 30K miles, we started experiencing engine noise, specifically a ticking sound from the valve train. We brought the vehicle back to the dealership at 50K miles, but they were unable to find any scarring after scoping the number 7 cylinder. Unfortunately, the noise continued to get louder. We brought the vehicle back a third time, but this time after the factory warranty had expired. The dealership found scarring and replaced the engine, but only after the original warranty had ended. We were grateful that we had purchased Certified at 12K miles and added the elite wrap protection. At 87K miles, we needed a new air compressor, seat heater elements, and running board approach lights. As our wrap coverage is due to end, we have decided to sell the vehicle.
Dagmar Upton 2024-06-25
My review is negative because of the car quality, not the overall company. However, I had a great experience with the local dealer here. I'm very disappointed with the QX80 2018. The quality of the backup camera and the 360-degree cameras is by far the worst in the car market. It looks like a camera from 10 years ago. The car also consumes too much gas. I'm averaging 11 miles in the city and 13.5 in the highway. I had big engine cars all my life, and this car is the worst in that department. When you pay over 75k for a car, you would expect a better backup camera. That's my biggest complaint with the car. At night, you can't even see anything.
Barney Swift 2024-06-06
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.
Sydney Rowe 2024-05-27
We purchased a 2016 QX80 that was loaded with features, just shy of the Limited version, for a price range of around 80,000 - 90,000. Unfortunately, the vehicle has not held its value and is now worth between 40,000-50,000 in less than a year. While we were initially drawn to Infiniti's large SUV as an elite luxury vehicle, we have come to realize that it does not quite measure up to our prior SUV. We are disappointed with our purchase and feel somewhat stuck due to the rapid depreciation. As of our one-year update, we are still dealing with the challenge of being upside down on our investment.
