What 1993 GMC Suburban owners say
Most recent owner complaints, unedited.
The passenger side shoulder strap does not tighten up.
Rear differential carrier on my 1993 suburban k1500 broke and locked the rear wheels, form my understanding this is a common occurance on these trucks and gm should be aware of how often these thinsg break and the potential for loss of vehicle control of this happened at high speed.
Rear ended someone due to the inability to stop in time due to the poor performance of the 1993 gmc suburban braking system. Brakes are a very big problem on this truck
Pressure must be applied to the windshield wipers in order for them to operate. This causes poor visibility during inclement weather.
The driver's side seat frame broke on the front left corner. Seat now rocks back 8-10 inches. Upon investigation, cause was due to very thin material.
While using windshield wipers and without any indication wipers would stop working intermittently.
There is a problem with the windshield wipers not coming on when turned on. Recall was for later year models, but this year model has the same problem. Why should I have to pay for a defect when someone who bought their vehicle a few months later with the same problem does not?
Windshield wiper motor failure. Wipers will suddenly quit working during operation. ** incident date listed below indicates approximately date of onset. This problem has been ongoing since this date (time we took ownership of vehicle).
Consumer states wipers work intermittenly. Please provide any further information.
