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 APPOINTMENTS WITH OWNERS AND TO REPAIR THEIR VEHICLES AS SOON AS POSSIBLE.

DEFECT INVOLVED

GENERAL MOTORS HAS DETERMINED THAT A DEFECT, WHICH RELATES TO MOTOR VEHICLE SAFETY, EXISTS IN CERTAIN 1993 C6/C7 TOPKICK/KODIAK, B7 SCHOOL BUS CHASSIS, AND P6 COMMERCIAL CHASSIS. SOME OF THESE VEHICLES WERE ASSEMBLED WITH LOOSE OR MISSING INTERMEDIATE STEERING SHAFT FASTENERS. IF THE FASTENERS ARE MISSING, THE INTERMEDIATE STEERING SHAFT CAN SEPARATE RESULTING IN A TOTAL LOSS OF STEERING CONTROL. THE LOSS OF STEERING CONTROL COULD CAUSE THE VEHICLE TO CRASH WITHOUT PRIOR WARNING.

TO PREVENT THIS CONDITION FROM OCCURRING, DEALERS ARE TO CORRECT INVOLVED VEHICLES PER THE SERVICE PROCEDURE IN THIS BULLETIN.
