What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Tl contact owns a 1993 gmc sierra c-1500 which was purchased used in 2007. She stated that the passenger side bench bolts broke which caused the seat to sway back and forth. There were no related recalls. The dealer was not notified. The failure and current mileages were over 200,000.
I have been having intermittent problems with the windshield wipers for the a couple of years. I finally decided to try and fix the problem and discovered this is not an unusual problem with gmc pickups. The windshield wipers may or may not work.
Windshield wipers work only intermittently. Dealer informed consumer that vehicle was out of its warranty, and there was nothing he would do.
As I proceeded down the road, the vibrating got worse. I pulled over to the side of the road but could not see a problem. Upon returning back to the road, the vibrating became more severe. I was able to make it onto an access road and into a service station parking lot.
Seatback bolts failed, causing driver to surge forward. Dealer has repaired bolts under a recall; however, problem has reoccurred. Manufacturer notified. In both cases the seat rear frame required replacement due to failed weld joints.
Windshield wipers would work intermittenly during use. Please provide further information.
While driving at 60mph the dashboard lights and meters started flashing and moving wildely. I then heard a loud screeching noice and smelled smoke. T alternator had completely self-destructed and burned up.
Every time driver enters vehicle, the driver's seatback would collapse. No back support on seat. Had seat replaced under recall in march 1996. Dealer refused to repair seat again.
