Wiring harness under drivers floor mat was damaged by the wearing of the mat by my guys boot over the years and the air bag deployed and dash started smoking. Why do they put wires under the floor mat? Fortunately he wasn't traveling very fast but imagine if he was on the hwy doing 60mph. Disaster. Now GMAC won't cover this and I have to pay almost $6, 000.00 to fix. I have 8 other Chevy vehicles and fear for my employees, my family and my safety. Haven't fixed it yet.
