Example complaints

Transmission and drivetrain: “03 Gmc sierra got used in aug 06 with 31000 miles now has 36000 miles and transmission has clunk between 2 &3 gears from all the research I have done it seems this is happening to lots of people I will bring this to GM`s attention because it still under Gmc certified warranty but I don`t think it will get me anywhere please help.”

NHTSA complaint #10174628, filed 2006-11, 33,000 miles

Electrical system: “I have a 2003 Gmc sierra 4wd truck and the speedometer cluster is bad. I see that thousands of other people have the same problem. The speedometer register erratically and sometimes stays on 0 MPH while driving down the highway. I here the fuel gauge is next to go bad. These two problems together on a busy highway can and will cause accidents where someone will get hurt or killed. Gm has agreed to recall these vehicles with under 70,000 miles and 5 yrs. Old. This does nothing to this safety problem but lower the odds a little bit. …”

NHTSA complaint #10373697, filed 2011-01, 82,000 miles

Engine cooling: “I noticed since I bought my 2003 Gmc envoy that the motor would race in the am upon starting. I took this as normal until the racing never stopped one day. I took it to my local GM dealer and they informed me the fan clutch had failed and repaired it for over 700$. Upon research later on this part I noticed people saying these are failing at a regular basis. Now, I'm not a mechanic, but I think had I not the knowledge I do of automobiles, I would have continued to drive and possibly could have had a major engine failure of some sorts. …”

NHTSA complaint #10140186, filed 2005-10, 40,000 miles
