What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
My truck completely shuts off while driving long distances on the freeway at speeds greater than 60 mph and then slowing down in stop and go traffic. It also falls dead on local roads at 30-40 mph. I can literally press the gas pedal to the floor and with no pressure to the accelerator.
There is an electrical malfunction that has caused my horn to work only when the steering wheel is sideways and it also affects my ability to control my drivers seat positioning. This is very dangerous a car cut me off on the freeway at very close distance.
When driving at slow speeds break light comes on, and the brakes vibrate. I've taken the car to the dealership and the technicians could not find the problem. I then shut off the engine and restarted the vehicle and the brakes worked properly.
The brake light came on the dash. I pulled off the highway and turned the car off. When I started the car again the brake light went out and the brakes acted as normal after that.
The brake light comes on, the brake pedal weakens and brake system makes a rattling noise when the pedal is pressed. It makes it very difficult to stop the car.
Tl* the contact owns a 2007 infiniti qx56. The contact stated that while driving at various speeds, the speedometer and tachometer on the instrument panel would fail to display the correct reading as well as while driving at night the instrument panel failed to illuminate.
Takata recall my airbag light has been flashing accompanied by some clicking sound or noise that stops after some seconds.this happens each time I turn on the car
Had new tires put on my infiniti qx56....after doing so sounds as if rear end is slipping. I have 3 children and am afraid that this could result in an accident. Horn quit working 1 year after I purchased vehicle. This I know is dangerous because there is no horn to blow, in cases where needed.
