The problem
SOME SPORT UTILITY VEHICLES EQUIPPED WITH AN ELECTRONICALLY CONTROLLED AIR SUSPENSION (ECAS) HAVE A CONDITION IN WHICH THE ECAS MAY PRODUCE A BRIEF ELECTRICAL SPIKE WHILE THE VEHICLE IS OPERATING. THIS ELECTRICAL SPIKE CAN DISRUPT THE POWERTRAIN CONTROL MODULE (PCM) CAUSING THE VEHICLE TO STALL.
Risk
IF THE SPIKE DAMAGES THE PCM, THE VEHICLE MAY NOT RESTART. IF THIS HAPPENS WHILE THE VEHICLE IS MOVING, A CRASH COULD OCCUR WITHOUT PRIOR WARNING.
What owners should do
DEALERS WILL INSTALL A WIRING HARNESS. THE RECALL WILL BEGIN ON AUGUST 19, 2004. OWNERS SHOULD CONTACT OLDSMOBILE AT 1-800-630-6537 OR GMC AT 1-866-996-9463.
