Three problems related to suspension have been reported for the 2002 GMC Sierra. The most recently reported issues are listed below.
This is an old incident; however, until just recently, I did not realize there was a website such as yours. Also, I am reporting a specific incident, but also want to include other general information. The incident which occurred was related to my brake fluid lines rusting completely through while I was driving down the road with my two small grandchildren. When a vehicle stopped in front of me, I pushed on my brakes only to find I could not stop. Fortunately, there was a field on the right side of the road and I drove into it, rather than hitting the vehicle. When my husband checked the brakes, the lines literally fell apart. We still have this truck, but the entire underside of it (frame, spring hangers, front drive shaft, etc) are all rusted. Another issue that happened earlier this summer - the spare tire carrier had become so rusted, my spare tire actually came lose while driving down the road. Fortunately it was held up by a chain. Upon learning that this is a problem with most all gm trucks, I felt obligated to base my complaint in the hopes that something can be done. Toyota faced similar problems, but fortunately stood behind their products and made it right with their customers and I feel gm should be required to do likewise. We have tried to trade this truck in for another vehicle, but are being offered way below kelly blue book price because of the rust issue.
There is rattle/vibration in my truck's steering column. Any time I go over an uneven surface I hear an annoying rattle coming from under the hood in front the steering wheel, and I feel a consistent vibration in the steering wheel. This rattle started with about 35,000 miles on the vehicle, just in time for the warranty to expire. My truck now has 60,000 miles on it with the same annoying problem. My dealer keeps telling me there is probably going to be a recall on it, so I don't want to pay to repair it (whatever may be wrong with it).
Vehicle pulls to the left at highway speeds. 2 attempts by the dealer have failed to remedy the situation. Consumer feels this condition presents a danger to himself and the general public whenever his full attention is diverted from trying to keep the vehicle going straight.
