Fuel system reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

There is a strong smell of gas on the driver side after I have been driving. Other innfinity QX80 owners reported online with the same model, that this is in fact a recall issue for this make and model, and year. However when i call Infinity, they say they cant find anything on my car. it is not?? however your website clearly lists it as a problem for this particular car?? what do i do next.

I have come to notice that when I put gas in my 2015 Infiniti (V8 engine vehicles only), QX80 vehicles. The fuel pressure sensors may not have been sufficiently tightened during production. As a result, the fuel pressure sensor may loosen with vehicle usage and cause a fuel leak.

I have been noticing intermittent gasoline smell outside of vehicle. It has been smelling stronger and more often so I decided to inspect it for the second. I removed the carpet and fuel pump cover and discovered the fuel pump is leaking gas. Now I cannot drive vehicle due to gasoline leaking every time the ignition is on. It is a serious safety and fire hazard. I have not contacted the dealer because it is not under warranty.

The most glaring safety issue caused by below is the SUV will try to move forward on its own while stopped and the brakes pressed that can potentially cause a fender bender. Infiniti/Nissan 5.6L engines have a history of failed or failing viscous cooling fan clutches. This goes back over a decade based on the TSG released by NISMO. When the viscous fan begins to fail, the most glaring symptom is that ECM will compensate by revving up the engine RPM...specially with the AC on. This can cause the RPM to go from around 500 to 1000 RPM during an RPM surge. The surge is enough to move the SUV forward at a stop unless the brake is firmly pressed. On hot weather days, this risk is frequent and significant at a top. This viscous fan issue also puts signficant load on the engine and causes significant power loss to the drive train. This issue does not cause any type of "check engine" light since it is strictly a mechanical failure of the mechanism containing the fluids in the viscous assembly.

I purchased a 2015 Infiniti QX80 on March 31, 2021. Since the purchase, I have only driven it approximately 6,000 miles and the check engine light has already come on. I took it to the dealership and they stated that both Catalytic Converters need to be replaced. This vehicle is only 6 years old; it should not need both Catalytic Converters replaced. Upon research, I discovered that there was a recall on 11/28/2014 for certain 2014-2015 Infiniti Q80 vehicles. My vehicle was not part of this recall, however, I know it should have been because I believe this is the reason for the Catalytic Converter failures on my car. Recall Fuel system, gasoline Recall date 2014-11-28 Recall no. 14V683000

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
