NHTSA lists 1 safety recall and 5 owner complaints for the 2027 Infiniti QX80. Most complaints involve fuel/propulsion system (3) and forward collision avoidance (1). The EPA rates it 17–18 mpg combined.
Nissan North America, Inc. (Nissan) is recalling certain 2020-2026 Nissan Armada, 2011-2013 Infiniti QX56, and 2014-2027 QX80 vehicles equipped with 22" wheels. The Gross Axle Weight Rating (GAWR) listed on the certification label is incorrect, which can allow the vehicle to be overloaded. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 110, "Tire Selection and Rims."
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“I am reporting a potential fuel/fire safety defect involving TWO brand-new 2027 Infiniti QX80s. My first QX80 developed a strong raw-gasoline odor after driving/shutdown, especially when parked in my residential garage. I repeatedly reported this to Infiniti. Various explanations were given, including Arizona heat and gasoline formulation. The dealer ultimately exchanged the vehicle. The replacement 2027 QX80 developed substantially the SAME gasoline odor after only about 12 miles from the dealership to my home. I returned it for evaluation. On XXX, Infiniti on Camelback inspected the replacement vehicle. This is no longer based solely on my observation. Their final repair order documents my complaint of “fuel smell coming from the rear driver side wheel area” and, importantly, states their inspector “had a fuel smell at the time of check in and in the shop while sitting in the shop.” The dealer found no codes or visible fuel leak. Therefore, an Infiniti dealer independently detected and documented the fuel odor. Afterward, I spoke with Service Director [XXX]. He told me he had discussed this same issue/condition with an Infiniti field engineer and that…”
“My 2027 INFINITI QX80 SPORT has repeated, extremely dangerous ProPILOT Assist steering failures that create a serious risk of collision. 1. FAILURE TO YIELD CONTROL: When I attempt to take over steering, ProPILOT does not reliably release control. Instead, it continues steering against my input with extreme physical force. I have to fight the steering wheel to prevent dangerous maneuvers. The resistance is far stronger than in any other vehicle with similar technology I have driven. 2. UNINTENDED LANE DEPARTURES: On straight roads with clearly visible markings, ProPILOT suddenly pulls the vehicle toward or across lane boundaries, sometimes toward lanes occupied by other vehicles. The system can continue forcing the vehicle toward traffic despite my attempts to correct it. 3. DANGEROUS DISENGAGEMENT: While I am applying significant force to resist the system, ProPILOT can suddenly release steering assistance, causing the vehicle to jerk sharply in the opposite direction. 4. REPEATED SWERVING: The system can violently steer between lane markings several times in succession, triggering repeated lane departure warnings while making aggressive steering corrections.…”
“The contact owns a 2027 Infiniti QX80. The contact stated that while driving at an undisclosed speed, an abnormal fuel odor was present. The odor became stronger after the vehicle was parked. No warning lights illuminated. The vehicle was taken to a dealer, where it was diagnosed that the fuel tank and evaporative emission control canister needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 10.”
