Recall 04V289000: Potential Stalling/PCM Damage
DEFECT: Certain 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. If the spike damages the PCM, the vehicle may not restart. If this happens while the vehicle is moving, a crash could occur.
REMEDY: Dealers will install a wiring harness. The manufacturer has reported that owner notification is expected to begin during July or August 2004. Owners may contact Oldsmobile at 1-800-630-6537 or GMC at 1-866-996-9463.
