4 consumer complaints on file.

FUEL/PROPULSION SYSTEM
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 Infiniti was aware of it. My understanding was that he was not aware of a specific repair, corrective procedure, or available fix at this time. I am extremely concerned because the same condition occurred in TWO new QX80s, the dealer confirmed the fuel odor, Infiniti field engineering is reportedly aware, yet no cause or fix has been provided. No diagnostic code or visible liquid leak explains why gasoline vapor/odor is present. My concern is fire risk and gasoline-vapor exposure, particularly when parked in an attached residential garage. I request NHTSA investigate the QX80 fuel/EVAP system and similar complaints. Vehicle and documentation are available for inspection. Infiniti Case #XXX. VIN: [XXX].

FUEL/PROPULSION SYSTEM
I purchased a new 2027 Infiniti QX80 Autograph, VIN [XXX], from Infiniti of [XXX] on XXX with approximately 10 miles. On XXX, the day after purchase, I contacted the dealer because I noticed a strong raw gasoline/fuel-vapor odor after driving the vehicle, shutting it off, and parking it inside my garage. The dealer initially advised me to wait 4-5 days because the vehicle was new and suggested the odor might resolve. The odor persisted. The vehicle had approximately 300 miles when the problem continued. I returned to the dealer and was advised that the fuel tank and/or EVAP canister might need replacement and that parts could take weeks, with no definite repair timeline. The suspected affected system is the fuel/EVAP system, including the fuel tank, EVAP canister, vapor-control system, fuel-system venting, or related components. The exact cause is UNKNOWN. The vehicle was available for dealer inspection. I am concerned because a strong raw gasoline/fuel-vapor odor in an enclosed residential garage may indicate abnormal fuel-vapor release and could create a potential fire hazard and expose occupants to fuel vapors. No warning lights or dashboard messages appeared. The primary symptom was the strong gasoline odor after normal driving and shutdown. Because of this unresolved safety concern, the dealer ultimately replaced this vehicle with another new 2027 QX80. The replacement vehicle later developed the same strong gasoline/fuel-vapor odor. I am concerned this may represent a broader fuel/EVAP system defect rather than an isolated problem. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FUEL/PROPULSION SYSTEM
I am filing this complaint regarding my replacement 2027 Infiniti QX80 Autograph, VIN [XXX]. My original new 2027 QX80 developed a strong raw gasoline/fuel-vapor odor shortly after purchase. I reported it to Infiniti of Scottsdale on XXX, one day after purchase. The dealer initially advised me to wait 4-5 days because the vehicle was new. The odor persisted, and the dealer later advised that the fuel tank and/or EVAP canister might need replacement. I filed NHTSA Case No. XXXfor that first vehicle. Infiniti of Scottsdale provided this replacement QX80 on XXX. Within one day, the replacement vehicle developed the same strong raw gasoline/fuel-vapor odor, especially after driving, shutting the vehicle off, and parking it inside my garage. I returned the replacement vehicle to the dealer on XXX because of the same condition. The suspected affected system is the fuel/EVAP system, including the fuel tank, EVAP canister, vapor-control system, or related components. The exact cause in the replacement vehicle is UNKNOWN. The vehicle is available for inspection through the dealership. I am concerned that strong gasoline vapors in an enclosed garage could present a potential fire hazard and expose occupants to fuel vapors. No warning lights or dashboard messages appeared. The primary symptom was the strong raw gasoline/fuel-vapor odor. The same condition occurring in two separate brand-new 2027 QX80 vehicles raises concern that this may be a broader fuel/EVAP system safety defect rather than an isolated problem.
