The Infiniti QX80 is often overshadowed by more popular rivals like the Lexus LX, Cadillac Escalade, Lincoln Navigator, and Mercedes-Benz GLS. Yet, this behemoth SUV has the same qualities: abundant power, ample passenger and cargo space, and a smooth ride.
This three-row Infiniti has something else in common with these plush rides: the need for proactive measures to maximize longevity. As is typical with most luxury vehicles, you can’t ignore maintenance, driving habits, and other ownership responsibilities.
So, assuming you want to keep your Infiniti QX80 on the road as long as possible, read on. We’ll explore common trouble spots for Infiniti owners, maintenance fundamentals, early warning signs of trouble, and being proactive about upkeep. Further, we’ll uncover how to protect your QX80’s functionality and your wallet if forward-thinking ownership can’t prevent an inevitable car repair.
Infiniti launched a full-size flagship SUV for the 2004 model year with the QX56. The name continued with the debut of the second-generation model for 2011. Following a reshuffling of the automaker’s model designations, the QX56 was rebadged as the QX80 for the 2014 model year.
While much of what’s covered in this article applies to all QX56s and QX80s, we’re paying particular attention to the 2014 through 2020 QX80 editions. Why? Because these models don’t have or will soon lose factory warranty protection. In addition, five- to ten-year-old vehicles represent a sweet spot in the used car arena. They’ve lost significant market value, making them more affordable than their newer counterparts. Yet, age also causes these vehicles to be more vulnerable to breakdowns and surprise repair bills. And, these model years have been on the road long enough for there to be sufficient reliability data.
While a new Infiniti QX80 starts at $85,000 and crosses into six-figure territory for higher trims, used examples cost significantly less. According to Autotrader, a 2014 QX80 costs $5,000 to $20,000, depending on condition, mileage, equipment, and marketplace factors. Prices range from $23,000 to $42,000 for a 2020 Infiniti QX80.
To get a real-world look at typical Infiniti QX80 problems, we analyzed owner complaints on file with the National Highway Traffic Safety Administration (NHTSA). This review revealed seven core trouble areas for the 2014 to 2020 Infiniti QX80:
While airbag and visibility issues (6 & 7 above) aren’t insignificant, they don’t represent most QX80 problems. Plus, these areas don’t involve primary mechanical systems like points 1-5. Let’s break down these primary trouble spots.
Multiple complaints highlight timing chain failures. Owners report stretched timing chains requiring costly repairs, often exceeding $4,000. Some relate the issue to earlier Infiniti models (the QX56) that had recalls for the same problem.
Owners frequently report fuel leaks and strong gasoline odors while parked, particularly in the garage. Some suspect issues with fuel pressure sensors that loosen over time.
Complaints include:
While some reports cover braking components like calipers, most brake-related reports involve unintended activation of the automatic emergency braking (AEB) system.
Paying attention to recalls is an essential component of car ownership. Here’s a brief summary of the recalls for the 2014-2020 Infiniti QX80:
QX80 Model Year | Recall Overview |
2020 | Fuel pump module issue where the impeller could swell and bind, potentially causing engine stall |
2019 | Back-up camera display issue where settings could make rear view image not visible |
2018 | Same back-up camera display issue as 2019 model |
2015 | Fuel pressure sensor that could loosen and cause fuel leak |
2014 | Three separate recalls: (1) Fuel pressure sensor that could loosen and cause fuel leak (2) Driver’s frontal airbag inflator defect that could cause metal fragments if deployed (3) Incorrect weight rating on certification label for vehicles with 20-inch wheels |
You’ll notice that one trouble spot, the fuel system, overlaps with some of the recalls. This underscores the importance of being alert to recalls, as Infiniti may cover these repairs.
Ensuring your SUV is on a regular maintenance schedule is as vital as being aware of common Infiniti QX80 issues. This vehicle is far from a rough-and-tumble pickup truck. The QX80’s sophisticated systems require ongoing servicing to safeguard optimal performance and minimize breakdown risk. Here’s an outline of what needs attention and when, but always refer to the QX80 owner’s manual for exact service requirements.
Catching problems early can save thousands in repair costs. Keeping in mind the earlier list of typical Infiniti QX80 troubles, we’ve outlined the warning signs for these areas and added another critical system, the transmission, to be watchful of.
Avoid any of these signals at your own peril. Swift action can prevent more extensive damage and a minor issue from turning into a major one.
Taking a proactive approach to your QX80’s maintenance requirements can pay off in many ways.

Owning an Infiniti QX80 without warranty protection leaves you vulnerable to a pricey driving experience. According to RepairPal, here’s a glimpse of what owners could face:
These numbers would be more like a down payment if work involved the engine or transmission. QX80 owners can find peace of mind with an Endurance Warranty plan (also called a vehicle service contract or auto protection plan).
Endurance offers a range of coverage options, including a powertrain program that safeguards the engine, transmission, and drive axles. Meanwhile, expanded plans protect the QX80 further, especially for those known trouble spots. Owners can also take advantage of the Supreme plan, which provides the ultimate coverage similar to new car bumper-to-bumper coverage.
No matter what you drive, every Endurance extended car warranty comes with valuable benefits, including 24/7 roadside assistance with towing, rental car reimbursement, trip interruption protection, and flexible payment terms. Importantly, you can take your car to any licensed facility for covered repairs. This is a particularly valuable perk if your QX80 needs specialized work that is only available at an Infiniti dealer.
