What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Consumer request assistance in getting gm to reimburse her for the defective parts installed in her 1988 suburban. While driving 60 mph the vehicle vibrated severely.
I just bought the vehicle in june and didn't realize that it had two atx tires on it until one went flat and I went to have it repaired. The tire dealer said the tread had separated and the tire was unsafe and should be replaced. He also said the recall had expired. How can a recall expire?
Shoulder belts needed to be replaced. Dealer did not seem concerned about safety aspect of problem. Manufacturer could only say that it was very poorly produced. They could only say it was discontinued. Consumer was willing to pay for the installation & equipment.
During collision consumers were ejected from vehicle. (attorney for consumers)
When jacking the truck up the gears, the jack locks up and the jack will not let the truck down. Please describe.
Four seat belts in vehicle, none of the buckles will lock.
Driver's seat back anchor bolt sheared off prior to recall (93v-187), causing seat to fall backwards. (other vehicle on 480470).
