Defect Involved, Dealer Action, Vehicles Involved & Owner Notification Information

DEFECT INVOLVED


General Motors has determined that a defect which relates to motor vehicle safety may exist in certain 1988 Pontiac Grand Prix model vehicles. The vehicles could have been assembled with wheel lug nuts not installed to specified torque. This condition could allow the lug nuts to loosen and/or come off the wheel studs. If this condition went unnoticed, it could eventually result in the wheel separating from the vehicle. Separation of a wheel from the vehicle could cause loss of vehicle control and a vehicle crash could occur.
DEALER ACTION


To prevent the possibility of this condition occurring, dealers are to inspect all involved vehicles to assure proper wheel nut torque. If lug nuts are loose or missing, they are to be replaced along with the wheel studs, according to the instructions included in this bulletin.

Involved vehicles have been identified by Vehicle Identification Number computer listings. Computer listings contain the complete Vehicle Identification Number, owner name and address data, and are furnished to the involved dealers with the campaign bulletin. Owner name and address data furnished will enable dealers to follow up with owners involved in this campaign.

These listings may contain owner names and addresses obtained from State Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of this listing to the follow up necessary to complete this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.
