I am not sure if this is the correct forum for voicing these concerns but I hope and can be enlightened about these problems. I am not sure of the exact mileage or dates of any of these incidents without further study. The seatbelts on this truck will lock up intermittently while driving down the street with no braking. The right windshield wiper has broken free from the mechanism twice. The daytime lighting does not work though the lamps and fuses are in working condtion. The power steering pump sheared a shaft in two and was replaced under warranty. The engine clatters and was fixed once by the dealer however the fix has never lasted more than half of an oil change(1,500 miles.) the headlight and rotary dimmer switches and surrounding trim on the dash get extreemely hot to the point of burning. I know I have missed something, it's hard to believe that so many things have gone wrong with this truck.
1999 GMC Sierra visibility complaints
Page 2 of 2: complaints 11 to 18 of 18, newest first, as owners wrote them.
While driving on an interstate highway at 60 MPH in a heavy rainstorm the nut that holds the passenger side windshield wiper arm onto the drive shaft backed off and the wiper arm contacted the driver side wiper arm and stopped both wipers from opperating.
The ABS system vibrates at a low rate and vehicle will not slow down when applying constant pressure on brakes. There appears to be a 2 to 3 second delay between the time ABS takes over and when you have come control over the braking of the vehicle. This time elapse causes you to use other means for avoiding an accident such as veering to the left or right to avoid contact during heavy braking. This problem will also occur if the rear drivetran loses contact with the road surface during light braking. The driver has to always be aware of the possibility of not being able to stop to be able to avoid an accident. The outside mirrors on this vehicle ices up completely during winter highway driving at highway speeds over 45 MPH. The time it takes for the mirrors to ice up completely is usually less than 15 minutes from initial start.
Consumer stood on tailgate and let it go. He landed on concrete ground. Contacted dealership, and mechanic told him that warranty expired. He wasn't hurt.
Power switches and motors failed.
