When driving at an undetermined speed vehicle surged forward. Consumer took the vehicle to the dealership for inspection but they were unable to resolve the problem.

problem #3

Sonoma

  • Automatic transmission
  • miles
Just pulled into the main street, drove a way down the road, and because brakes did not catch, rear ended another automobile. Brake pedal went to the floor. Also, while braking the engine was racing, which made it harder for auto to slow down.

Engine accelerates on its own at times while vehicle is in motion. If the clutch is disengaged during the failure, the engine wll run around 3000 RPM for approx. 15 seconds before it returns to normal idle. Dealer claims no codes and engine is operating to specifications. They test drove and could not duplicate the problem. Their statement to me was " we can not fix it if we do not know what to fix". I asked them if they had called GMC to trouble shoot the problem and their reply was yes and they did not know and had no other reports of this problem. I picked the truck up from the dealer on 9/21 and drove it on 9/22 around town with no problem. Then on 9/23 after a 3 stop shopping trip, the truck incured the same problem as before. My dealer has offered to keep the truck for a couple of days of test driving but I am affraid that they will not be able to duplicate the problem since they drove it 60 miles the first time they had it.
