He said I can call GM to report the issue and that they may offer me a deal to split the cost since the vehicle is out of warranty. …”
NHTSA complaint #10174101, filed 2006-11, 82,000 miles“In november of 2005 I was driving along when for no reason I felt a burning on the inside of my left thigh. It got so hot it I almost lost control of the truck. I had to pull over to find out that it was my heated seat that had just burned out and does nt work anymore. At that point I just figured it was just another thing that broke, but on 2/2/06 a person I work with just told me she had the exact same problem and almost lost control of her vehicle. She has a 2004 buick rainier which is almost the same as my 2003 chevy trailblazer. …”
