I've had several problems with the truck since I bought it 3 months ago. I've fixed almost all of them-ABS was activating which was pushing me into traffic nearly causing a wreck so I changed the ABS speed sensor and hub assembly. Front suspension was gone so I replaced that; as well as steering parts, brakes, the parking brake doesn't work, fixing it next. Oil sending unit, A/C belt and refrigerant replaced. The problems left are evap emission vent valve solenoid, throttle pedal position sensor, and random/ multiple cylinder misfire sometimes and cylinder 4 misfire other times. In 4X4 when it gets under a load something sounds like it's binding up and it pops but it still works. When I shift into drive or reverse or accelerate from a stop it has a shift feeling in the rear with a thump sound. Sometimes I can push the gas and it won't downshift to speed up when I'm on the hwy but that's probably the tpps. I just want my 4X4 working and my shift thump from a stop to go away. Help. In 4X4 the noise happens in fwd reverse and when turning and worse in 4lo but happens in 4hi and auto but not in 2hi.

While trying to sell my vehicle, an auto service facility discovered serious frame corrosion which could prove to be a safety issue. The corrosion seems excessive and suggests design and/or material deficiencies. I have had to replace all brake lines and have had transmission shift linkage failure, all due to rust. Also, excessive body rust in the lower rocker panels has occurred, more of a cosmetic problem, but indicative of the pervasive rust problem that exists.

The contact owns a 2000 GMC Sierra 1500. The contact received a recall notice for the service brakes wheel speed sensor. On September 19, 2007, the dealer repaired the recall; however, the ABS and brake warning lights have been illuminated since the recall repair was performed. While driving between 15 and 50 mph, the vehicle made a loud noise. The dealer stated that the wheel speed sensor and wheel bearings were one unit. The dealer also stated that they cleaned one side and the other side did not need to be cleaned. The service manager confirmed that they used force to remove parts from the vehicle and stated that the vehicle was able to withstand much more damage than what occurred. During the recall repair, the dealer damaged the front ball joint and dented the rotors. The driver side ball joints were replaced; however, the failure is worse than it was prior to having the recall repair performed. The dealer was unable to provide the contact with an invoice. When the ABS light is illuminated, the brakes fail to operate normally. The contact has to shut off the engine to allow the ABS to reset itself. A second diagnosis by a different dealer revealed that the driver and front passenger side wheel bearings were damaged, including the passenger side that was repaired for the recall. The second dealer further stated that the noise was due to the wheel bearings failing to move freely. The manufacturer was informed by the dealer that there was no noise present. The manufacturer provided the contact with claim number 71558918083. The approximate failure mileage was 106,500 and current mileage was 108,500. Updated 03/05/08. The consumer stated informed dealer many times for the ticking heard in the vehicle since the vehicle at the time purchase. Updated 03/04/08
