Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Gauges work some times and don't,lights go off and on the dash when they do this at night it's hard to see what speed your doing our how much fuel you have. This seems to be a problem with a lot of the trucks my neighbors truck is doing the same thing.”

NHTSA complaint #10593022, filed 2014-05, 69,000 miles

“My 2004 Gmc sierra would light all four turn signals when the left turn signal was applied, as if the hazard lights were on. Took it to dealer and they said they had never seen anything like it before. Paid almost 200 dollars to get it looked at and fixed. After going home, I see that other sierra users have the same problem. More shocking, I see that GM had the exact same problems with some envoys, barbados, trailblazers, and others, and performed a safety recall at no charge. It is outrageous that all vehicle owners with these problems were not notified and the faulty components replaced. …”

NHTSA complaint #10176628, filed 2006-12, 45,760 miles

“When the weather is below freezing the turn signals do not work until the vehicle has warmed up for atleast 20 minutes. Also the speedometer does not work, and when it does start working it is never the correct reading. It will stick as high as 70 MPH, and to bring it down I have to keep restarting and shutting off the engine.”
