CAMPAIGN:STOPLAMP SWITCH INOPERATIVE. Chevrolet Corsica 1992

For 1990-2009 cars

# CAMPAIGN:STOPLAMP SWITCH INOPERATIVE

#### SUBJECT: PRODUCT SAFETY CAMPAIGN 92C29 - STOPLAMP SWITCH INOPERATIVE

#### MODEL AND YEAR: 1992 CHEVROLET BERETTA AND CORSICA

#### 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 1992 Chevrolet Beretta and Corsica model vehicles. Some of these vehicles exhibit a condition in which the service brake stoplamp switch becomes inoperative, resulting in failure of the service brake stoplamps to illuminate when the service brake pedal is actuated. If this condition occurs during three (3) consecutive service brake applications, the amber ABS (Anti-Lock Brake System) instrument panel telltale lamp may be illuminated. If the stoplamps fail to illuminate in situations where a driver in a trailing vehicle is otherwise unable to recognize a braking action in sufficient time to respond appropriately, a vehicle crash could occur without prior warning.

To prevent the possibility of this condition occurring on your vehicle, dealers are to replace the vehicle service brake stoplamp switch and correct the wiring in the service brake stoplamp switch wiring harness connector.

VEHICLES INVOLVED

Involved are certain 1992 Chevrolet Beretta and Corsica model vehicles built within the following VIN breakpoints:

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.

REASON FOR THIS RECALL

General Motors has determined that a defect which relates to motor vehicle safety exists in certain 1992 Chevrolet Beretta and Corsica model vehicles. Some of these vehicles exhibit a condition in which the service brake stoplamp switch becomes inoperative, resulting in failure of the service brake stoplamps to illuminate when the service brake pedal is actuated. If this condition occurs during three (3) consecutive service brake applications, the amber ABS (Anti-Lock Brake System) instrument panel telltale lamp may be illuminated. If the stoplamps fail to illuminate in situations where a driver in a trailing vehicle is otherwise unable to recognize a stopping action in sufficient time to respond appropriately, a vehicle crash could occur without prior warning.

WHAT WE WILL DO

To prevent the possibility of this condition occurring, your dealer will replace the service brake stoplamp switch and correct the wiring in the service brake stoplamp switch harness for your vehicle. 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. 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 one half hour. 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).

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.
