2005 Sierra 1500 4X4 I bought this truck new 01/ 2005, the rear spring shackles failed on 02/20/2014 due to rust, I took it to the dealer and they said the rear 3ft of frame is badly rusted making it not roadworthy. Gms position is that this is somehow neglect on my part and will not do anything. The body of the truck is not rusted and still looks good. I find it unreasonable that a 9yr old truck with no body rust should have the frame so rusted as to make it unsafe to drive.

The rear upper frame mount for the shock absorber failed due to corrosion. The non-paint rubberized coating placed on the entire frame of this vehicle is flaking off and exposing the bare steel to the elements. The frame of this vehicle has more rust than should be expected on a 50 year-old truck but it is less than eight years old. The truck is well taken care of and the body shows no signs of rust. The failure of the non-paint rubberized frame coating has rendered this 2005 Sierra un-drivable.

The contact owns a 2005 GMC Sierra 2500hd. The contact stated that when attempting to brake at low speeds, the front end would shake and the braking distance would increase. The contact also stated that the vehicle would pull toward the right when the failure occurred. An authorized dealer stated that this was a known failure, but this year, make and model was not recalled. The failure and current mileages were 72,000. Updated 02/09/12 the front wheel bearing assembly and sensor were replaced. Updated 02/13/12

Front driver side and passenger side wheel bearings and ABS sensors went bad. I have spoke to other owners of similar vehicles and they also had trouble.

2005 GMC Sierra slt VIN [xxx] I drove the truck 237 miles home and noticed it was not operating properly. I called GMC to resolve the problems. The truck has binding in the front axles, brakes, or differential. This causes the truck to understeer heavily as the truck works to turn the front wheels over the road surface. This also makes the truck difficult to steer, U turns are especially a problem, the truck has sluggish acceleration and stays longer in the lower gears. The rear tires are prone to lose traction due to the increased rolling resistance from the front wheels, braking performance is compromised, the truck will sway back and forth at highway speeds as the rolling resistance of the front wheels varies from side to side. The truck tends to pull to the left, and the suspension is always preloaded from the additional stress. The engine labors to maintain speed on level ground with the vehicle unloaded. On occasion the front wheels will hop off the pavement as it is easier for them to compress the suspension/torsion bars than be turned over the road. It is difficult to maintain a straight line with the truck since the front wheels tend to follow the Contour of the road. The front wheel assemblies make a low frequency sound when driving. The transmission, engine, and drivetrain components are always loaded and driving on snow or ice would be treacherous since the front wheels would stop turning on the low friction surface. Driving in the rain is bad enough and the rear wheels tend to break loose. The transmission has behaved strangely, stuttering on occasion as it tried to find the proper gear, it has slipped or freewheeled as I went to accelerate from a stop. The wrong oil filter was installed, the air cleaner is loose and rattles in the engine compartment. The power steering provides little or no assist and requires more effort than I have ever experienced from a vehicle that is supposed to have power steering.
