Engine check light has come on at least 6 different occasions. The dealer reported an assigned reason for the failure each time. Then on the last occurrece they did not even trouble-shoot the failure. Instead they reprogrammed the prom for the engine. Immediately after this my fuel economy went for 12-14 mpg to 8-9 mpg, the engine idle is rough (sometimes almost stalls) and on occasion there is a fuel smell. After complaining about these items the dealer "can not find anything wrong" GMC has refused all my attemps to have a regional support manager contact me. In addition to this the fuel pump has made a loud buzzing noise ( you can hear inside the vehicle with the windows up). The dealer said this was "normal".
Wet surface. Two similar wrecks in two different chevy pickups. One a 1994 and the other in a 2000 GMC. Trying to stop, standing on the brakes, while both of these vehicles accelerated into the rear of the vehicle in front of me. Following the last incident, I went straight to a large empty parking lot and duplicated the acceleration while standing on brakes.
