What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The front driver side air bag failed to deploy. The contact sustained head and neck injuries that required medical attention. A police report was filed. The manufacturer was not notified of the failure. The vehicle was destroyed and towed. The vin was not available. The approximate failure mileage was 120,000.
Made a right turn onto a round about street and when I tried to turn left my steering wheel locked straight like if the car was parked. The wheels wouldn't turn and I hit a parked truck where a person was working on. He did get injured but I am not aware of the exact injuries he sustained.
Rear-end collision. Result: death of driver in car hit - 2005 infiniti g35 2door. Spare tire assembly had been changed for this model year. Factory installed bolt securing spare was too short. On collision spare tire launched by impact through the rear seat striking and killing driver.
Brakes failed on infinity g35 and resulted in an automobile accident where infinity hit another car.
The vehicle was taken to the dealer where the recall repair was completed; however, the contact stated that while driving at an undisclosed speed, the air bag warning light illuminated. The dealer was not notified of the failure. The vehicle was not diagnosed or repaired.
The contact stated while driving 55 MPH, there was an abnormal sound as if the sunroof was opened. The contact stated that the sunroof was glued in place to a rubber gasket which had started coming apart. The contact called a local dealer and was informed that the sunroof was no longer available.
The fuel gauge is not reading correctly, and I have to rely on knowing my mileage and how much I last filled in my tank. I have to keep the car running longer than necessary to even duplicate the problem, and when I do the gas gauge just suddenly starts dropping.
The contact stated that while driving at various speeds, the vehicle locked up and stalled on four occasions. The contact was able to restart the vehicle. The check engine and slip warning lights were illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired.
