I went out one morning and started my truck and heard a rattle noise coming from the engine. I got out and opened the hood. Almost instantaneously the engine backfired and the cooling fan blew apart and fragments of metal came through the plastic shroud and into my face and head causing serious and would have been fatal injury to myself. If it were not for the fast response of the paramedics who flew me to the hospital by chopper. I am now blind missing an eye and my face and head are scared along with possible brain damage. Please do whatever it takes to keep this tragic accident from happening to anyone else.

I purchased a 1993 gmc sierra pickup for my son from my father who was the original owner. My father took very good care of it making all scheduled maintenances as we have done as well after purchasing it. My son was on his way to school when all of a sudden the steering column broke. He was unable to steer the truck and had to come to a complete stop after going approximately 50 MPH. Luckily he did not loose control nor did he crash head on into the on coming lane of traffic. Once stopped he couldn't get the ignition to turn off with the key. Had to jiggle the steering column around to shut off the engine. He did this without the key in the ignition. We had the truck towed back to our home and are in the process of fixing it.

While driving in rain with my wipers on low speed, they suddenly stopped, just as a truck was passing me, with the road water thrown on the windshield by the semi, I could not see the road ahead. I could see in my side mirror that I was clear on my right side, so I pulled over on the shoulder and stopped. I also own a 1991 3/4 ton silverado which I have had trouble with the wiper delay function, although they have not totally stopped as the sierra's did. I spoke with some other gm truck owners who say they have experienced similar issues with the wiper systems of their trucks, some as far back as 1988 models.

Replaced the transmission 4 times, recall on seats were fixed but bolts keep breaking so I bought new seats of a differnt style and replaced them after a 5 year problem. Paint has been flaking off the truck for appoximately 4 yrs and I cant get the dealer or gm to do anything with this paint problem. They say it is because I am the second owner. The truck was in an accident but the top of the cab and the bed is all that needs painted, and they were not damaged in anyway because of the accident.

#1 transmission. Slips out of gear into nuetral while driving at highway speeds. Must coast over to side of road, turn off engine, wait, restart and continue on. Narrowly caused a collision with a semi truck while coasting to side of road. Complained to dealer numerous times, said they could not find anything wrong. Now trans is locked in 2nd gear and won't shift to a higher gear. #2 paint. Started chipping within 6 months old and less than 2500 miles. Dealers said nothing could be done. Roof is now rusted through and headliner is hanging down. Dealer and zone rep say gmc is not responsible and refuse to repair and repaint. #3 seat belt retractor. Driver's seat belt will not retract and is very loose. It would not prevent injury or death if involved in a crash. Dealer and zone rep deny responsibility and refuse to repair except at my expense. #4 radio. Radio has been replaced 3 times by the dealer since new and they refuse to replace or repair it again. Volume must be turned up all the way to be heard. This is the exact same problem with every radio they say they have replaced.
