What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Takata recall air bag did not deploy when stationery 2002 infiniti qx4 stopped at traffic light on city street was hit in the rear by another vehicle which was accelerating. Pushed infiniti qx4 25 feet into oncoming traffic.
I am filing a complaint about the front drivers side seat belt and shoulder harness. When seat belt is fastened, the shoulder harness rubs your neck while driving, so in the event of an accident I believe the shoulder harness will cut and injure the drivers neck. This is serious and should be replaced.
Sudden acceleration propelled the car forward and hit the wall head-on, despite effort to brake. There was a surging power sound and the car was clearly accelerating. At least one of the rear wheels continued to revolve under power after the car was stopped against the wall.
During the incident the contact had brake failure and the air bags failed to deploy. There was frontal damage to the vehicle. The vehicle has not been inspected by the dealership. The vehicle was towed to a body shop for the necessary body repairs.
Drivers side low beam failure (2000 pathfinder and 2006 titan also same issue) Replaced bulbs twice in one year now low beam headlight doesnât work at all always the driver side
My issues are related to the SAFETY RECALL CAMPAIGN 1997-2003 QX4 IN SALT STATES FRONT STRUT HOUSING CORROSION. I brought my car in for the recall at [dealer], Minnesota and they only fixed the Driverâs side strut housing using a brace but only painted the Passengerâs side.
I have tried to get passenger airbag recall (and a confirmed driver seatbelt defect) replaced and the part was needed one year ago around march or april 2020 and today when I tried to make a appointment 03/29/2021 was told that it is a 3 to 4 hour job and no loaner vehicle or tow is available for this type of service.
Extensive rust and decay is found on the passenger side frame where the lower control arm connects. This is just below the strut housing and is visible through the front wheel well. I have attached both passenger and driver side photos as the defect only appears on the passenger side.
