Three problems related to dash wiring have been reported for the 2000 GMC Sierra. The most recently reported issues are listed below.
The accelerator had stuck, the transmission slipped, the flaps on the fender and the door trim had fallen off, the back window leaked, the heat shield was believed to have caused a vibration in the dash-per service dealer, the coolant light stayed on, the a/c had to be repaired twice, and the rotors vibrated.
Power steering pump shaft broke, causing loss of steering and inability to control vehicle. The faulty circuit cluster in the dashboard caused all guages to fail. The vehicle experiences noise in the front end.
When I press on the brake pedals on a sudden stop on bumpy roads at speeds over 30 mph, the brake pedal does not depress. The brake pedal vibrates and the vehicle does not stop properly. It takes the truck a longer time to stop than normal. This almost casued me to rear end cars on more than one ocassion. I had to take my foot of the brake pedal and reapply pressure to get firm brake pressure. When the brake pedal vibrates, it gives a false sense of abs working but the truck stops slower than if it were the abs. Sudden stops on bumpy roads are very dangerous.
