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…

The airbag system in my recently purchased (4 months ago)QX80 Infiniti 2015 is malfunctioning/failed. It is available for inspection upon request. The warning light came on within 2 months of my purchase. I took it to the dealerships for repair, was told âthis is unusual for this age car & mileageâ stating it was the driver curtain airbag module which I paid a large amount to have replaced. When I received the car back, the warning light was no longer on. A month & a half later, the warning light returned. Took it back to the same dealership where I am now told that when it was repaired prior it was merely a guess as to the problem & that now a different part of the system needs…
