Speedometer stopped working at approx 45,000 mi. Followed by oil pressure and voltmeter at approx 60,000 mi. Also coolant leak behind timing cover at approx 50,000 mi.
Speedometer doesn't read correct speed. Speedometer needle sticks and then when you start again it will start reading from where it was stopped so if it sticks at 30 mph and you resume speed to 60 mph it will read 90 mph.

Failure of speedometer and oil gauge. Was contacted by gm to replace the instrument panel. Because I had more than 70k miles they said it will not be replaced. Even though they admit to a failure of the system, since I cannot prove it happened within the 70k mileage they are refusing to replace it. This is a tremendous hazard and is very costly to replace. A dealer quoted me $850. Thanks for your help.
Instrument cluster malfunction. To the best of my knowledge the only gauges working properly are the tachometer and fuel gauge. It began with intermittent speedometer malfunction. Took it in as warranty work but the service dept. Could not duplicate the issue. After the warranty expired the issue resurfaced. I asked about any recalls or complaints regarding the cluster gauges malfunctioning at every visit for service. No recalls or complaints received according to them. Did some research on the subject. Found a few similar complaints in blogs but no action from gm. The problem began to cascade and soon all gauges except for the tach and fuel began to fail. Not fix as of yet. Gm has a notice out on it but refuses to repair my truck due to having too many miles. They even found documentation at the dealership service dept. For the original speedometer malfunction but they state it wasn't a strong enough complaint.
2004 GMC 2500 instrument panel defect concerning gauges. Consumer states that the gauges stick and the manufacturer sent out a letter stating this problem and a solution as long as the vehicle had less than 70, 000 miles or 7 years old. The consumer stated the restriction on the time/mileage was unreasonable for any person who lives in rural America. The consumer stated people drive an average of 15,000-20,000 miles per year.
