My vehicle has 86,200 miles on it and I have to have both heads rebuilt because of a burnt exhaust valve. I have been told multiple times that this should not be happening at this low mileage on the vehicle. The engine idles really rough when in park or not in drive or motion. When stopped at a stop light, the "service traction, service esc, esc off" comes on. This goes away once you start driving again.
