Example complaints

Brakes: “I was driving at 45 MPH and applied the brake to stop. The engine revved to 2,000 RPM. I was able to stop with very hard braking using both feet. The engine continue revving at 2,000 RPM even after the car had stopped. I placed the transmission in neutral and the engine revved even faster. The engine did not slow down until I turned off the ignition. After leaving the engine off for around two minutes, I restarted the engine and it resumed running at around 500 RPM. …”

NHTSA complaint #10514506, filed 2013-05, 27,000 miles

Steering: “About a month ago I contacted Beechmont Ford (600 Ohio Pike Cincinnati, Ohio 45245) in reference to Manufacturer Recall Number # 13S08 NHTSA Recall Number # 13V385000. I've wrote them three time and they have not responded. A week ago I chatted with Fords Hotline and they said they would do what they could. I've heard nothing back. Where do I go from here?”

NHTSA complaint #11609513, filed 2024-08

Electrical system: “On october 21, 2016, while I was driving on I-30 in dallas county, a fire occurred in the daimay-supplied driver-side visor lamp assembly of my 2009 ford Mercury Grand Marquis. The ford fuse system failed, allowing the fire to burn, melting portions of the visor and roof material. The melted material fell on my left leg and the driver seat and floor of the vehicle, causing 2nd and 3rd degree burns to my leg. Chrysler notified NHTSA of a similar defect in the daimay assembly on july 1, 2014, which resulted in the first of two chrysler recalls on july 10, 2014. …”

NHTSA complaint #11042676, filed 2017-11, 49,984 miles

Vehicle speed control: “I applied the brakes at around 20 miles per hour on january 25 and the motor accelerated for one or two seconds. I was able to stop the car by pressing the brakes much harder than normal. On january 26 I applied the brakes at around 60 miles per hour and the motor again accelerated for one or two seconds. I continued to press the brakes, the motor slowed down and the car eventually slowed. It sounded like pressing the accelerator down hard to pass another car on a two lane road.”
