general problems of the 2003 GMC C2500

Gauge instrument cluster defective on 2003 GMC sierra. Speedometer reading incorrect speed. Considered a safety defect. Unable to accurately determine vehicle speed. General motors dealerships unwilling to repair defective parts.

Speedometer , fuel gauge etc. Went at 93,000 miles. GMC knows of this problem and will only fix it on a limited basis. Not every one was informed of this problem and they will only fix it if you are under 70k miles.

Faulty speedometer, reads120mph most of the time.

2003 GMC sierra pickup w/49000 miles. Speedometer has started erratic readings which presents a safety hazzard when driving.

Pulling out of a parking lot on wet pavement my rear truck tires spun a bit and then when I got on the road traveling about 50 mph my speedometer read 120 mph! when I came to a complete stop the needle stayed at about 70 mph. The problem is I don't know how fast I am going, but I can guarantee that it wasn't 120 mph! :) truck is still not working. Vehicle is a 2003 GMC 2500hd.

I have a 2003 GMC diesel pickup. I have had the vehicle in twice for electrical repairs in the last 9 months. The electrical problems observed include: airconditioner cutting in/out, radio cutting in/out, power windows not working, dash gauges cutting in/out, idiot lights coming on (abs, brakes, check engine etc). It was repaired once by the dealership at a cost of $500. Now, 9 months later, the vehicle is back in for the exact same problem. The techniciain took it for a ride and had so many problems, he was afraid he wouldn't make it back to the dealership.
