“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.”

“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. …”

“This vehicle has an issue with uncontrolled acceleration when I first take off. With my brake pedal applied the engine RPM is approx. 550, which is in specs. As soon as I release the brakes the RPM jumps to 1100 RPM and the vehicle takes off on it's on. My vehicle has been to the dealer twice for this problem and they say they can't help me, my first experience I almost rear ended the vehicle in front of me. This an issue that needs addressed. Street conditions, weather conditions don't make a difference, and has done it since I purchased it.”
