# CAMPAIGN: FRONT SHOULDER BELT RETRACTOR-REDUCED SENSITIVITY

#### Subject: PRODUCT SAFETY CAMPAIGN 9OC36 - FRONT SHOULDER BELT RETRACTOR

#### Model and Year: 1988-90 CHEVROLET CORSICA AND BERETTA W/ PASSIVE RESTRAINT SYSTEM -----------------------------------------------------------------------------

#### To: All Chevrolet Dealers

The National Traffic and Motor Vehicle 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 owner 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 owner 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 solutions, every effort must be made to promptly schedule an appointment with each owner and to repair their vehicle as soon as possible. As you will see in reading the attached copy of the letter that is being sent to owners, the owners are being instructed to contact the Chevrolet Customer Assistance Center if their dealer does not remedy the condition within five (5) days of the mutually agreed upon service date. I f 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 determined that a defect which relates to motor vehicle safety exists in certain 1988-90 Chevrolet Corsica and Beretta model vehicles. Some of these vehicles 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 replace the front shoulder belt retractors and belt assemblies in involved vehicles.

#### VEHICLES INVOLVED

Involved are certain 1988-90 Chevrolet Corsica and Beretta model vehicles built within the following VIN breakpoints:

December, 1991

Dear 1988-90 Chevrolet Corsica/Beretta Owner:

This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.

REASON FOR THIS RECALL

General Motors has determined that a defect which relates to motor vehicle safety exists in certain 1988-90 Chevrolet Corsica/Beretta model vehicles equipped door mounted shoulder and lap safety belt systems (passive restraints). Some of these vehicles exhibit a condition in which the front shoulder belt retractors 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 only by a 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.

WHAT WE WILL DO

To prevent the possibility of this condition occurring on your vehicle, your dealer will replace the front seat shoulder belt retractors and belt assemblies. This service will be performed for you at no charge.

WHAT YOU SHOULD DO

Please contact your Chevrolet dealer as soon as possible to arrange a service date and so the dealer may order the necessary parts for the repair. Be sure to tell the dealer the color of your interior so that the dealer can have the correct color belt assemblies when you take your vehicle in for this repair.

Instructions for making this correction have been sent to your dealer and parts are available. The labor time necessary to perform this service correction is approximately (2) hours. Please ask your dealer if you wish to know how much additional time will be needed to schedule and process your vehicle.

Your Chevrolet dealer is best equipped to obtain parts and provide service to ensure that your vehicle is corrected as promptly as possible. If, however, you take your vehicle to your dealer on the agreed service date, and they do not remedy this condition on that date or within five (5) days, we recommend you contact the Chevrolet Customer Assistance Center by calling 1-800-222-1020.

After contacting your dealer and the Customer Assistance Center, if you are still not satisfied that we have done our best to remedy this condition without charge and within a reasonable time, you may wish to write the Administrator, National Highway Traffic Safety Administration, 400 Seventh Street, S.W., Washington, D.C. 20590 or call 1-800-424-9393 (Washington D.C. residents use 366-0123).

The enclosed owner reply card identifies your vehicle. Presentation of this card to your dealer will assist in making the necessary correction in the shortest possible time. If you have sold or traded your vehicle, please let us know by completing the postage paid reply card and returning it to us.

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

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.
