CONDITION
General Motors has decided that certain 2002 Chevrolet Venture, Pontiac Montana, and Oldsmobile Silhouette U-Van model vehicles with All Wheel Drive (AWD) have an ABS software error. Under some driving maneuvers with the compact spare tire installed, the software error can result in the AWD Rear Drive Module (RDM) clutches not disengaging resulting in excessive slip of the clutches. The driver would notice odor and noise and premature wear to the clutch could result. If the vehicle continues to be driven, the clutch would lose ability to transfer power.
CORRECTION
Dealers are to replace the ABS module Electronic Control Unit (ECU) with an ECU with updated software.
VEHICLES INVOLVED
Involved are certain 2002 Chevrolet Venture, Pontiac Montana, and Oldsmobile Silhouette U-Van model vehicles equipped with AWD RPO and built within the VIN breakpoints shown.
IMPORTANT:
Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) or GM Access Screen (Canada only) or DCS Screen 445 (IPC only) prior to beginning recall repairs. [Not all vehicles within the above breakpoints may be involved.]
Involved vehicles have been identified by Vehicle Identification Number. Computer listings containing the complete Vehicle Identification Number, customer name and address data have been prepared, and are being furnished to involved dealers with the recall bulletin. The customer name and address data furnished will enable dealers to follow up with customers involved in this recall. Any dealer not receiving a computer listing with the recall bulletin has no involved vehicles currently assigned.
These dealer listings may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this recall.
