2015 Infiniti QX80 Complaints

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 viscou...

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 “this is unusual for this age car & mileage” 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 replacing (airbag diag system) “in hopes of this being the issue” There is also an accompanying hefty price for this repair. But I was also told (at this juncture) that if this part replacement did not take care of the problem, the next step would be to replace the airbag wiring harness which would cost $7,500...

2015-2019 model year Nissan and Infiniti vehicles suffer from an on-board computer algorithm defect that can cause the side curtain airbag to spontaneously deploy.

The contact owns a 2015 Infiniti QX80. The contact stated while the vehicle was parked at the residence, he attempted to start the vehicle and the vehicle failed to start. There were no warning lights illuminated. The contact waited for a while before attempting to restart the vehicle. The vehicle was towed to an independent mechanic and was diagnosed with a defective fuel pump. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 95,000.

Airbag light started flashing continuously while driving home on an 8 hour road trip on the interstate. I brought the car to the dealership once returning home, and they stated that they found a code for the left hand curtain air bag module assembly. Then proceeded to tell me that the driver side curtain airbag module assembly needs to be replaced, and if the light continues to flash then the wire harness will need to be replaced as well. This is a serious safety issue. If my vehicle would have been in an accident my airbags may not have deployed. There may be a defect in the side curtain airbags with this vehicle. I know that there is a lawsuit in Utah due to nissan and infiniti vehicles made between the years 2015-2019 due to driver side curtain airbags spontaneously deploying while driving in a normal and safe manner. This leads me to believe that something is faulty concerning the side curtain airbags in these vehicles. My SUV was purchased new, and has always been serviced a...
