Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Speedometer just quit working, jumps from 10 to 70+. Shows a minimum of 10 MPH parked. Not exactly safe to not have a clue how fast your going. I searched on the net suspecting an isolated problem, but found this has affected 8 to 10 models for 4 plus years, are you kidding me. Just one of thousands with the same dangerous problem!!!!!”
NHTSA complaint #10251526, filed 2008-12, 91,723 miles“Speedometer fails to function - will be traveling down the road and it ranges from 0-120 MPH when I estimate I am actually traveling 35 MPH(estimated obviously). Has happened on 3 occasions and in now non-functioning. Dealership recommends replacing instrument cluster - and admits to a rash of these replacements on these trucks.”
NHTSA complaint #10181979, filed 2007-02, 81,800 miles“I purchased the truck used with 83,000 miles in august of 2007. About a month later the water temp gauge moved all the way around and then went back to zero and stopped working. Then the speedometer was stuck for a few days and started working again. But for how long? And now I've heard GM issued an extended warranty just for the gauges and must have under 70,000 miles instead of a recall.”
NHTSA complaint #10224093, filed 2008-04, 84,000 miles“My whole dashboard stops working the gauges lights everything just stopped working. I was traveling down interstate and everything stopped working but after a few seconds it all came back on for about 30 seconds and it all shut off again and never came back on I made it home and turned the truck off and went inside. I got up the next morning to go to work and cranked the truck and no gauges or lights were not working still. I slammed my hand down on top of the dashboard and everything came on and was working but that didn't last long and everything shut off again.”
NHTSA complaint #11122408, filed 2018-08, 203,112 miles“Speedometer records wrong speed gradually moving ahead to pegging self at 120 MPH. Each time vehicle was stopped speedometer will correct by 5 MPH. Thus, I did not know speed I was moving at. Started vehicle enough times to move back to 0.”
