# CAMPAIGN: PASSENGER SIDE INFLATABLE RESTRAINT (PSIR)

#### NOTE: GM OF CANADA CAMPAIGN 96066 IS LOCATED BELOW THE U.S. VERSION

#### PRODUCT SAFETY CAMPAIGN

#### SUBJECT: 96066 - PASSENGER SIDE INFLATABLE RESTRAINT (PSIR) MAY ------------------------------------------------------ SNAG ON INSTRUMENT PANEL REINFORCEMENT --------------------------------------

#### MODELS: CERTAIN 1996 'N' VEHICLES -------------------------

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 entitied 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 1996 Buick Skylark and Oldsmobile Achieva vehicles. During deployment of the passenger air bag, the air bag fabric may snag on a reinforcement inside the instrument panel, causing the expanding bag to lift the instrument panel pad and then deploy under the instrument panel pad instead of through the door in the instrument panel. The reinforcement may also fracture. In a crash, the front seat passenger could receive more severe injuries if he or she contacts a broken reinforcement or if the snagging affects the deployment of the bag.

To prevent the possibility of this condition occurring, dealers are to inspect I/P pads and, if necessary, install a plastic edge protector to the instrument panel pad reinforcement. On certain early-production vehicles, the instrument panel pad will be replaced.

#### VEHICLES INVOLVED

Involved are certain 1996 Buick Skylark and Oldsmobile Achieva ('N' body) vehicles built within the following VIN breakpoints:

PLANT YEAR DIVISION MODEL PLANT CODE FROM THROUGH ---- ---------- ------- ------- ----- -------- -------- 1996 Buick Skylark Lansing "C" TC400000 TC402620 1996 Oldsmobile Achieva Lansing "M" TM300000 TM301590 1996 Buick Skylark Lansing "C" TC402621 TC426252 1996 Oldsmobile Achieva Lansing "M" TM3Ol591 TM325078

#### NOTICE: Dealers should confirm vehicle eligibility through VISS (Vehicle Information Service System) prior to beginning campaign repairs.

Please note that there are two groups of vehicles in the above table.

- The first group (early production) requires complete removal of the I/P pad for inspection and service.

- The second group requires partial dis-assembly of the I/P for inspection and service.

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. Customer name and address data furnished will enable dealers to follow-up with customers involved in this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

These dealer listings may contain customer 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.

November 1996

Dear General Motors Customer:

General Motors of Canada Limited has decided that a defect which relates to motor vehicle safety exists in certain 1996 Buick Skylark and Oldsmobile Achieva vehicles. During deployment of the passenger air bag, the air bag fabric may snag on a reinforcement inside the instrument panel, causing the expanding bag to lift the instrument panel pad and then deploy under the instrument panel pad instead of through the door in the instrument panel. The reinforcement may also fracture. In a crash, the front seat passenger could receive more severe injuries if he or she contacts a broken reinforcement or if the snagging affects the deployment of the bag.

To prevent the possibility of this condition occurring, your GM dealer will install a plastic edge protector to the instrument panel pad reinforcement. On certain early-production vehicles, the instrument panel pad will be replaced.

This service will be provided for you at no charge.

Please contact your GM dealer as soon as possible to arrange a service date.

If parts are required, ask your dealer for details regarding their availability. If parts are not in stock, they can be ordered before scheduling your service date.

This letter identifies your vehicle. Presentation of this letter to your dealer will assist their Service personnel in completing the necessary correction to your vehicle in the shortest possible time.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our products.

Customer Support Department General Motors of Canada Limited
