2015 INFINITI QX80

The contact owns a 2015 Infiniti QX80. The contact stated that while driving at 60 MPH, the rear passenger-side wheel began to detach from the control arm, causing the driver to lose control of the vehicle. Despite the failure, the contact was able to pull over to the highway shoulder. Upon inspection, the contact observed that the rear passenger-side tire was resting at a 45-degree angle. The vehicle was towed to an independent mechanic, where it was discovered that the rear control arm was severely corroded. The mechanic then informed the contact that an unknown TSB was related to the failure, and the contact was referred to the manufacturer for assistance. The manufacturer was notified of the failure and informed the contact that there was no recall or warranty coverage on the vehicle. The contact was provided a case number and was referred to the dealer, who determined that the entire rear subframe needed to be replaced. The dealer had given the contact's mechanic an estimate for the repair. The vehicle had yet to be repaired and remained in the mechanic's possession. The failure mileage was approximately 135,000.

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.

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 $7,500.00 (total for all these “repairs” would be above $12,500) If they believe they had repaired the problem with the first repair, why do they not start there? Is/was my driver’s side airbag system working after the first repair or not or was the warning system just reset? I’m concerned that if they only can “believe” they have fixed the problem, how can I be assured that the system IS REPAIRED & will work in case of an accident? Did the system actually “work” with the first repair only to stop working or then oddly another component stop working a month & a half later? I was not able to be assured that even if the harness (most expensive repair of the 3) is replaced that this would actually take care of the problem either. I was told this is the “next step” in the Infiniti step decision tree. I DO NOT FEEL SAFE. I have looked for recall info but have not found any recalls. I am wanting to know if this problem/issue has been reported before on this make/model/year vehicle. Thank you
