Example complaints

“I was driving at 55 miles per hour and the truck just stopped running. There was no warning. I had to pull over fast to avoid an accident. The truck only has 40,000 miles on it. The dealership says that it is a fuel cell and that it is not covered under my 100,000 mile warranty.”
NHTSA complaint #10314107, filed 2010-02, 40,000 miles“Why is GM recall 14121 limited to new vehicles? It has been a recurrent, common problem since long before 2000. Long before I bought my 2007 Gmc Sierra Classic 2500hd which is on the third repair. I just replaced a transmission cooler line in my driveway. Today. Which is steadily eroding by way of continuous transmission cooler leaks. It continuously coats the underside of vehicle, reducing life of belts and hoses. Gm dealers feel its not covered by 5/100k powertrain warranty, or 36k bumper-bumper warranty because it's a long time GM problem as well as warranties in general.”
