For 1990-2009 cars

# Product Safety - Rear Cradle Bolt Retainer Corrosion

Subject: | 97016A -- Rear Cradle Bolt Retainer Corrosion

Models: | 1990 and Early 1991 Chevrolet Lumina Minivan, Oldsmobile Silhouette and Pontiac Trans Sport (In Corrosion Areas Only)

This campaign bulletin supersedes and replaces campaign bulletin 97016.

All W body vehicles (1988-90 and early 1991 Buick Regal, Chevrolet Lumina, Oldsmobile Cutlass Supreme, and Pontiac Grand Prix) have been removed from Campaign 97016. W body vehicles previously included in Campaign 97016 are now included in either Campaign 00061A or Campaign 00065A.

The Highway Safety Act, as amended, provides that each vehicle which is subject to a recall campaign of this type must be adequately repaired within a reasonable time after the customer has tendered it for repair. A failure to repair within sixty (60) days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time.

If the condition is not adequately repaired within a reasonable time, the customer may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation.

To avoid having to provide these burdensome remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible. As you will see in reading the attached copy of the divisional letter that is being sent to customers, the customers are being instructed to contact the appropriate Customer Assistance Center if their dealer does not remedy the condition within five (5) days of the mutually agreed upon service date. If the condition is not remedied within a reasonable time, they are instructed on how to contact the National Highway Traffic Safety Administration.

### Defect Involved

General Motors has decided that a defect which relates to motor vehicle safety exists in certain 1990 and early 1991 Chevrolet Lumina minivan, Oldsmobile Silhouette and Pontiac Trans Sport model vehicles located in the following areas:

Header | Header | Header | Header
--- | --- | --- | ---
Connecticut | Massachusetts | New York | Vermont
Illinois | Michigan | Ohio | Wisconsin
Indiana | New Hampshire | Pennsylvania
Maine | New Jersey | Rhode Island

AFFECTED VEHICLES ARE ALSO REGISTERED IN ONTARIO, QUEBEC, NEW BRUNSWICK, NOVA SCOTIA, NEWFOUNDLAND AND PRINCE EDWARD ISLAND.

These vehicles may exhibit a condition whereby the rear cradle bolts pull through the retainers due to corrosion of the retainer. If both bolts pull through, the rear cradle would no longer be supported at these mounting locations and the intermediate steering shaft may separate from the steering gear. If this were to occur while the vehicle was in motion, a vehicle crash could result without prior warning.

To correct the possibility of this condition, dealers will replace the rear cradle bolts and retainers.

### Vehicles Involved

Involved are certain 1990 and early 1991 Chevrolet Lumina minivan, Oldsmobile Silhouette and Pontiac Trans Sport model vehicles built within the following VIN breakpoints:

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 campaign bulletin.

Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this campaign.
