Speedometer is very erratic. When I am at a dead stop the speedometer says 70 mph and it tops out at 120 mph when I am doing only 30 mph.

Speedometer reads incorrect or not at all.

Speedometer started reading inaccurate speeds. Lately it reads 55 mph when at a stop and pegs out at around 60 mph. Replacement ranges from $220 for "do it yourself" kit with old part needing to be returned for core charge to $650 and up from the dealer. Still haven't fixed problem. Part is still in the vehicle.

Speedometer on my 2003 Z71 Avalanche works erratically or not at all. A significant safety issue I went to the dealership from who I bought my vehicle. Dealership said there was no recall on speedometer (instrument clusters) for my type of vehicle and that they could not replace the cluster as part of "goodwill" by GM because they have not been instructed to do so. They were not aware of the fact that many Avalanche and other GM SUVS have identical problems (usually a bad stepper motor in the instrument cluster). Cost to replace cluster is about $350-$400 including labor. Given the nature of the failure and how widespread it is, I think the NHTSA engineers should investigate this problem and perhaps tell GM they need to recall these vehicles before accidents occur. I have to estimate my speeds on a vehicle with only 58000 miles on it. I have read reports where speedometer failures have occurred within 10,000 miles.

The speedometer on my 2003 Avalanche went out. It registers up to 120 mph sitting still. The tachometer recently went out, also. Very dangerous for my wife (who drives the vehicle) and my children. I have seen hundreds of similar complaints on the internet. Why is there no recall?

Speedometer sticking on 2003 Chevrolet Avalanche 1500 4WD, nothing leads up to it just driving and it sticks at a certain speed wont correct itself, to correct it you have to unhook battery cables and then it is ok for a while until it sticks again, this has happened over 4 times now have been waiting for a recall to fix problem. This can not be caused by bad driving by owner or improper maintenance, this is something electronic.

Speedometer failure on our 2003 Chevrolet Avalanche at 43,000 miles. Speed does not register whatsoever or displays, for example, 20 mph when traveling in excess of 60 mph. It is a dangerous situation; a distraction and not knowing one's rate of travel. GM should address this problem.
