2003 Chevrolet Suburban Owner Comments

My wife drives a Chevrolet Tahoe 2003 ls with about 48 000 miles on it. Recently I was driving on the interstate and noticed the speedometer was showing 90 mph. I looked at other cars around me and decided may be I was going a little fast. So I slowed down a bit. The speedometer went up to 100. After I pulling over and stopped it went down slowly after I stopped. During the next week, the speedometer continued to increase and eventually stuck at the highest speed. So I made some calls to various dealers, and was told that several people have had this problem, and that it was going to cost $500 to fix the instrument cluster. I think this is a safety issue and want to notify Chevrolet. I think this is their problem. I don't want to pay for this one. Yesterday evening, the speedometer appeared to be working again. This time I've noticed it will track on the right speed and then have to come to a complete stop to sort of reset it.

While making a turn light came on indicating brake system failure in a matter of seconds. Then, everything shut down. Consumer lost the ability to steer or brake. After struggling consumer managed to pull the vehicle to the side of the road. After waiting a few minutes consumer attempted to restart the vehicle, but it would not turn over. It had no power. Consumer had the vehicle towed to a Chevrolet dealer for inspection, and mechanic determined that a short in a fuel pump wire caused a fuse to blow out, which in turn, shut down the entire system. Consumer stated that dealer put vehicle on the diagnostic machine, and the main computer showed no failure. However, prior to this incident there had been some other electrical problems.

Seat belt straps in the driver's and middle seat in the second row become tight to the point that the passenger must unbuckle the seat belt and reattach as the ride progresses. Also, the middle seat belt has released on a number of occassions sending my daughter flying to the front of the vehicle in her car seat on hard braking. Second, the audio controls behind the center console become extremely hot, even more so when they are in use.
