PRODUCT RECALL CAMPAIGN

PRODUCT SAFETY CAMPAIGN

SUBJECT: 98044 - FUEL TANK MAY CONTACT BODY SILL

MODELS: 1995-1998 CHEVROLET AND GMC C/K CREW CABS (FLINT ASSEMBLY ONLY

THE HIGHWAY 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 CUSTOMER 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 CUSTOMER 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 REMEDIES, EVERY EFFORT MUST BE MADE TO PROMPTLY SCHEDULE AN APPOINTMENT WITH EACH CUSTOMER AND TO REPAIR THEIR VEHICLE AS SOON AS POSSIBLE. AS YOU WILL SEE IN READING THE ATTACHED COPY OF THE DIVISIONAL LETTER THAT IS BEING SENT TO CUSTOMERS, THE CUSTOMERS ARE BEING INSTRUCTED TO CONTACT THE APPROPRIATE 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 DECIDED THAT A DEFECT WHICH RELATES TO MOTOR VEHICLE SAFETY EXISTS IN CERTAIN 1995-98 C/K CREW CAB PICKUPS. SOME OF THESE VEHICLES EXHIBIT A CONDITION IN WHICH THE FRONT, INNER CORNER OF THE FUEL TANK MAY CONTACT THE BODY SILL EITHER INTERMITTENTLY OR CONSTANTLY. THE RELATIVE MOVEMENT BETWEEN THE BODY SILL AND FUEL TANK COULD CAUSE A DISCERNIBLE NOISE; HOWEVER, OVER TIME, IT COULD WEAR A HOLE IN OR CRACK THE FUEL TANK AT THE POINT OF CONTACT. THIS CONDITION COULD RESULT IN FUEL LEAKAGE AND A DISTINCT FUEL ODOR IF THE TANK WERE FILLED ABOVE THE LEVEL OF THE HOLE OR CRACK. IF AN IGNITION SOURCE WERE PRESENT, THE FUEL LEAKAGE COULD RESULT IN A VEHICLE FIRE WITHOUT PRIOR WARNING.

TO PREVENT THE POSSIBILITY OF THIS CONDITION OCCURRING, DEALERS ARE TO INSPECT THE FUEL TANK FOR WEAR, AND EITHER INSTALL A SPACER BETWEEN THE FUEL TANK AND THE FRONT CROSSMEMBER, OR IF NECESSARY, REPLACE THE FUEL TANK.

VEHICLES INVOLVED

INVOLVED ARE 1995-98 CREW CAB PICKUPS BUILT AT FLINT ASSEMBLY PLANT AND WITHIN THE FOLLOWING VIN BREAKPOINTS:
