I was in a accident with my 1994 gmc jimmy . It just stopped in the middle of the interstate and I am here to say that I was scared to death and I am not sure what happened but I was in the hospital for four days. So can you please advise me on what I can do about it? Accident date is march 13,2016.
Then the brakes failed and I was not able to stop. Hitting the car in front of me. There was no damage to my car or the car I hit. I have not been able to make the truck do this again.
Last year the loss of braking was expereinced and a sensor on the abs system was replaced. This recent accident occurred after 6500 miles on the replaced sensor.
Consumer stated that while stopped at a stop sign he was rear-ended and seat belt retractor was not working, consumer went forward upon impact.
While pulling into a parking space at 10 mph and applying the brakes, pedal was hard to push, and the pedal stayed up very high. Consumer hit a fire hydrant and the vehicle came to a stop.
8/17/99 car throttle stuck and I put on brakes skidding 30 feet until I pulled keys and slammed shift into park. The dealer ( service manager don ) disclaims any service bullitins to this problem. Our family is afraid to drive the car. The car has been to the dealer for this problem without sucess.
