Example complaints

Brakes: “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 same issue has happened twice, once at lax, and the most recent being today 6/11/2019.”

NHTSA complaint #11219651, filed 2019-06, 84,000 miles

Suspension: “I purchased new tires at Infiniti of coconut creek september 2012. There is a vibration and noise at low speed, below 30 MPH. I took it back to the dealer numerous times and was told it is not the tires, it is the suspension that is loose and I will just have to live with it. Per the dealer, Infiniti knows there is a problem with the suspension on the QX56 and the armada and there is no fix. They will not replace the suspension.”

NHTSA complaint #10479359, filed 2012-10, 49,900 miles

Electrical system: “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. I would have never known that there was an issue if this did not happen.”

NHTSA complaint #11271137, filed 2019-10, 22 miles

Steering: “Vehicle feels as though it is jumping side by side on the road while driving over small bumps on the pavement. Requires firm grip on steering wheel to maintain control.”
