PRODUCT SAFETY CAMPAIGN - LOSS OF HEADLAMP OPERATION

1991 PONTIAC GRAND PRIX COUPE

TO: ALL PONTIAC 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 PONTIAC 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 DETERMINED THAT A DEFECT WHICH RELATES TO MOTOR VEHICLE SAFETY EXISTS IN CERTAIN 1991 PONTIAC GRAND PRIX COUPE MODEL VEHICLES. THESE VEHICLES EXHIBIT A CONDITION IN WHICH THE FOG LAMPS, LOW BEAM HEADLAMPS AND HIGH BEAM HEADLAMPS CAN BE OPERATED SIMULTANEOUSLY. THIS CONDITION VIOLATES LAWS IN SOME STATES WHICH ONLY PERMIT THE OPERATION OF FOUR (4) WHITE LIGHTS AT THE SAME TIME.

ADDITIONALLY, ALL THREE SETS OF HEADLAMPS OPERATING SIMULTANEOUSLY MAY CAUSE THE HEADLAMP CIRCUIT BREAKER TO BECOME OVERLOADED AND "TRIP" RESULTING IN THE LOSS OF HEADLAMP (HIGH AND LOW BEAM) AND FOG LAMP OPERATION.

TO CORRECT THIS CONDITION, DEALERS ARE TO INSTALL A NEW FOG LAMP RELAY, NEW CIRCUIT BREAKER AND NEW CIRCUIT BREAKER TERMINALS. THE VEHICLE CIRCUITRY WILL ALSO BE MODIFIED TO PREVENT THE FOG LAMPS AND HIGH BEAM HEADLAMPS FROM OPERATING SIMULTANEOUSLY.

VEHICLES INVOLVED

INVOLVED ARE CERTAIN 1991 PONTIAC GRAND PRIX COUPE MODEL VEHICLES BUILT WITHIN THE FOLLOWING VIN BREAKPOINTS:

INVOLVED VEHICLES HAVE BEEN IDENTIFIED BY VEHICLE IDENTIFICATION NUMBER COMPUTER LISTINGS. COMPUTER LISTINGS CONTAIN THE COMPLETE VEHICLE IDENTIFICATION NUMBER, OWNER NAME AND ADDRESS DATA, AND ARE FURNISHED TO INVOLVED DEALERS WITH THE CAMPAIGN BULLETIN. OWNER NAME AND ADDRESS DATA FURNISHED WILL ENABLE DEALERS TO FOLLOW-UP WITH OWNERS INVOLVED IN THIS CAMPAIGN.

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.
