CAMPAIGN: FRONT SHOULDER BELT RETRACTOR-REDUCED SENSITIVITY. Chevrolet Corsica 1990

For 1990-2009 cars

# CAMPAIGN: FRONT SHOULDER BELT RETRACTOR-REDUCED SENSITIVITY

#### SUBJECT: FRONT SHOULDER BELT RETRACTOR

U.S. Campaign Number Cross Reference: Chev Pont 9OC36 Canada Only

#### Models: Certain 1988 Chevrolet Beretta and certain 1989-90 Chevrolet Corsica/Beretta and Pontiac Tempest with Passive Restraint System

#### TO: ALL GENERAL MOTORS DEALERS

General Motors of Canada Limited has determined that a defect which relates to motor vehicle safety exists in certain 1988 Chevrolet Beretta and certain 1989-90 Chevrolet Corsica/Beretta and Pontiac Tempest model vehicles. Some of these vehicles may exhibit a condition in which the front shoulder belt retractor may have reduced sensitivity of the lock-up feature. During sudden deceleration, the lock-up feature may not operate properly and the operator and/or front seat passenger may be restrained by only the lap belt. In the event of a vehicle crash or other sudden deceleration, this condition may result in the increased possibility and/or severity of injury to the driver and/or front seat passenger.

To prevent this condition from occurring, dealers are to inspect to determine if the vehicle has a passive (door mounted) or active ("B" pillar mounted) safety belt system. If the vehicle has a passive safety belt system, dealers are to replace the front shoulder belt retractors and belt assemblies.

#### VEHICLES INVOLVED:

Involved are certain 1988 Chevrolet Beretta and certain 1989-90 Chevrolet Corsica/Beretta and Pontiac Tempest model vehicles built within the following VIN break points:

#### VEHICLE RECALL NOTICE

Dear General Motors Customer.

General Motors of Canada Limited has determined that a defect which relates to motor vehicle safety exists in certain 1988 Chevrolet Beretta and certain 1989-90 Chevrolet Corsica/Beretta and Pontiac Tempest model vehicles. Some of these vehicles may exhibit a condition in which the front shoulder belt retractor may have reduced sensitivity of the lock-up feature. During sudden deceleration, the lock-up feature may not operate properly and the operator and/or front seat passenger may be restrained by only the lap belt. In the event of a vehicle crash or other sudden decleration, this condition may result in the increased possibility and/or severity of injury to the driver and/or front seat passenger.

To prevent this condition from occurring, dealers are to inspect to determine if the vehicle has a passive (door mounted) or active ("B" pillar mounted) safety belt system.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
