CAMPAIGN: SECONDARY LATCH ASSY (UNEXPECTED HOOD OPENING). Buick Coachbuilder 1991

For 1990-2009 cars

# CAMPAIGN: SECONDARY LATCH ASSY (UNEXPECTED HOOD OPENING)

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 FACIA 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 BUICK 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.

CONDITION

GENERAL MOTORS HAS DETERMINED THAT A DEFECT WHICH RELATES TO MOTOR VEHICLE SAFETY EXISTS IN CERTAIN 1991-92 BUICK ROADMASTER MODEL VEHICLES. THE SECONDARY HOOD LATCH ASSEMBLIES IN THESE VEHICLES CAN CORRODE CAUSING A VERY HIGH LATCH RELEASE EFFORT AND POSSIBLY PREVENTING THE HOOD FROM LATCHING PROPERLY WHEN IT IS CLOSED. IF THE SECONDARY HOOD LATCH IS NOT PROPERLY ENGAGED AND THE PRIMARY HOOD LATCH WAS ALSO NOT ENGAGED, THE HOOD COULD OPEN UNEXPECTEDLY. IF THIS WERE TO OCCUR WHILE THE VEHICLE WAS IN MOTION, THE HOOD MAY CONTACT THE WINDSHIELD, REDUCING THE FORWARD VISION AREA OF THE DRIVER, AND A VEHICLE CRASH WITHOUT PRIOR WARNING COULD RESULT.

DEALER ACTION

TO PREVENT THIS CONDITION FROM OCCURRING, DEALERS ARE TO INSTALL A NEW SECONDARY HOOD LATCH ASSEMBLY WITH IMPROVED CORROSION RESISTANCE.

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.
