“The speedometer sticks at a speed and will drop to the 6 o'clock position. This is a know issue among owners but GM nor the dealerships are willing to acknowledge or fix it. This is the second issue with my vehicle that GM is not willing to fix or take responsibility. I will never purchase another GM vehicle again.”
NHTSA complaint #10694091, filed 2015-03, 108,784 miles“I pulled off on the side of the freeway to take a call. I started up my truck stepped on the gas to get back on the freeway and all of a sudden my speedometer went from 0 to the other end of the reading. It stayed there all the way home so I could not tell how fast I was driving. When I stopped, it started to go back down but as I would press the gas it would go all the way past the highest reading. It seems to get stuck now and then.”
NHTSA complaint #10499280, filed 2013-02, 128,000 miles“While traveling on the interstate in my 2005 chevy Avalanche I noticed that my speedometer read 90mph vs. 40/45mph. I pulled off the highway and placed the vehicle in park and the speedometer read 50mph while the vehicle was stopped. Gm states that my vehicles VIN do not fall within the range of their bulletin for recalls.”
NHTSA complaint #10273153, filed 2009-06, 53,000 miles“Speedometer has stopped working properly. It may not move at all or it may tell me I am going 120 MPH. I know of several other Avalanche owners that have had or are having the save problem. The vehicle has less than 47,000 miles. I spoke to the dealer and was told there is a recall on older models, but not on my 05.”
NHTSA complaint #10247563, filed 2008-11, 46,500 miles“Speedometer stopped working completely. It had been working fine when I last drove it. But when I started driving within the next 3-4 hours I noticed it was not reading the speed at all. All the other gauges on the cluster were working properly. When talking to the dealership about this problem they stated it wasn't a simple fix and could cost me above $500, they couldn't give me an estimate of how much it would cost. .after reviewing the complaints listed on this website, this seems to be a manufacturers defect. …”
