Engine and engine cooling
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.
Fix: 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.
