Verbatim excerpts from NHTSA complaints, by component

Service brakes

46 reports
“Brake Failure. The brake fails occasionally while driving on the streets or on the Highways without Waring. The brake pedal goes down to the floor, and grinding/hitting metal to metal sound is heard and vehicle brake control is lost. Experiences were traumatic; you swing left or right to avoid hitting another vehicle from behind or running a red light. The vehicle has been inspected by an independent mechanic, and the brake components: rotors, pads, drum, and fluid levels were ok, each time it occurs. The brake lights come off and on and each time, the mechanic finds no issues with the brake components. One dangerous aspect of these occurrences is that after the vehicle sits for a while, like 30 minutes to one hour, and you go back to driving the vehicle, it appears that the brakes readjust and starts working normally; it continues to work normally about a month, and out of nowhere without warning it fails again and readjusts later. I was about to take my daughter to college out of County, and she has a lot of luggage as she lives in the dormitory; we would not use this Infinity which is a large SUV that could have accommodated me, my daughter and my wife,…”

“The contact owns a 2006 Infiniti QX56.

Additionally, the check engine warning light and a sensor warning light were illuminated. The vehicle was taken to the dealer, where it was diagnosed that an Intelligent Cruise Control (ICC) distance sensor malfunction might have caused the failure. The manufacturer was notified of the failure, and a case was filed. The failure mileage was approximately 249,000.”
