What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The air bags did not deploy. The contact received notification of nhtsa campaign numbers: 15v319000 (air bags) and 16v384000 (air bags); however, the remedy was not available. A police report was filed.
I never had a warning light or any indication that the srs system was at fault . This mustang had a full frontal impact . I did contact ford about this issue and I was told { you can't afford to litigate a case against us } I would have to prove that if the airbags did deploy my injury's would of been less serious .
During this time the air bags never deployed or the passenger seat belt caught. The passenger was bounced all around the car. The passengers of the car were looking straight down at the road when the car was spinning on the nose.
Dt*: the contact stated while driving 50 mph in the rain and shifting from 3rd to 4th gear, the rear of the vehicle began to hydroplane. The contact let up off the gas, and steered into the skid. The steering did nothing.
The contact stated the front passengerâs side seat belt was difficult to latch and detach. The contact stated that several times the seat belt failed to detach. The seat belt warning light was illuminated stating that the seat belt was not engaged when it was engaged.
Tl* the contact owns a 2005 ford mustang gt. The contact stated that the vehicle would not accelerate when the accelerator pedal was depressed. The vehicle was taken to an independent mechanic who stated the transmission sensor and gear ratio were malfunctioning. The vehicle was driven back home.
Tire valve stem had a total and complete failure on the highway at top speed. Tires were correctly inflated but the valve stems failed where the rubber meets the wheel. This has happened 3 times in the last 9 months which destroyed the tire every time.
I noticed my radio turned off. Then also noticed my headlights and blinkers were also not working. After reaching my destination before it got too dark I stopped and tested all lights including brake lights.
