While driving the brake and ABS lights on the instrument panel light up. This has occurred while driving of the freeway and on city streets. Sometimes these lights go off and sometimes they remain lighted. When this happens I fear that there is a problem with the brakes and have taken this matter to a mechanic. The brakes were examined and he found nothing wrong. This is very startling to the driver and of great concern. This appears on internet searches and it appears that 100,000 plus individuals have this problem. I have contacted the dealer and obviously this matter has been brought to there attention. Yet they claim they are unfamiliar and want to charge $600 to diagnose and then likely more to fix. This is obviously a lie as there is no way that one could be reading so much about this on the internet if it was not a problem in the GMC Sierra trucks. Some claim it is a faulty circuit board while others have lost the use of their brakes. This is of great concern. This occurs while driving and the vehicle is in motion and sometimes at high speeds on a freeway.
I purchased this truck used and was able to use for a bout a month before both rear spring perches broke allowing the springs to rest under the pickup body, after replacing them the brake lines ruptured because of rust another poor quality product from GM !
The contact owns a 2000 GMC Sierra 2500. While driving approximately 35 mph, the rear of the vehicle slightly lowered towards the ground. The vehicle was driven with caution to the contact's residence. The contact inspected the vehicle and noticed that that the driver side main frame rail was fractured in the center. Additionally, the passenger side main rail was partially fractured. The failure was beyond repair. The contact mentioned that the brake line and rear cross member near the fuel tank were completely corroded. The manufacturer was not notified of the failure. The approximate failure mileage was 92,000.
I was turning around in my driveway, when suddenly the brake peddle went to the floor and all braking power was lost. Tried pumping the brakes multiple times with no success. There was no warning (lights or otherwise) before the incident, and no dash lights lit during the incident either.
