Wires underneath dash of my 2007 silverado crew cab caught on fire on 10/28/08. Smoke came pouring out of the dash. Called dealer and had them tow vehicle to john megal chevy in dawsonville, GA. Tore dash apart only to claim that the installation of an after market brake system caused the fire. Would not cover repair under warranty. Had to pay $376. 95 before they would let us move the truck to the other mechanic that installed the brake system. After mechanic that installed it reviewed the truck, claimed that is should have been covered under warranty. Claims brake system was installed correctly. I spoke with 2 more independent trailer dealers and they confirmed it was installed properly. John megel chevy would not cover under warranty even after our research and other professionals confirmed. We had to pay $1300 to have all wiring replaced, $300 in truck rentals, $376. 95 to john megel. We are out $2000 for something that gm should have handled. The disrespect we were shown from this dealer is unbelievable.
