I RECENTLY PURCHASED A USED 2000 CHEVY S-10 WITH 48,000 MILES. THE VEHICLE IS EXTRA CLEAN AND THERE WERE NO APPARENT PROBLEMS. I HAD TO MAKE A TRIP FROM ATLANTA, GA TO CHICAGO, IL. COMING BACK ON THE INTERSTATE (TRAVELING 75-80 MILES AN HOUR), THE CHECK ENGINE LIGHT CAME ON AND THE TRUCK DOWNSHIFTED FROM OVERDRIVE INTO THIRD. I WAS NEARLY REAR ENDED BY TWO 18-WHEELERS WHILE I TRIED TO SLOW THE VEHICLE SO THAT THE RPM'S WERE NOT IN THE CRITICAL ZONE. I STOPPED AT THE FIRST AUTO REPAIR SHOP I COULD FIND, AND WAS TOLD THAT THE TRANSMISSION WAS SEVERELY DAMAGED AND WOULD NEED TO BE REBUILT. APPARENTLY, THE BANDS WERE SLIPPING AND CAUSED THE FLUID TO OVERHEAT AND TURN EXTREMELY DARK. THE TRUCK NOW HAS 58,000 MILES, AND NEEDS A NEW TRANSMISSION. THIS IS THE THIRD GM CAR THAT I HAVE HAD THAT I HAVE HAD TO HAVE MAJOR TRANSMISSION WORK DONE. THE LAST ONE WAS A BUICK AND HAD LESS THAN 60,000 MILES ON IT. *LA

Official recalls
4Sep 8, 2000
VEHICLE DESCRIPTION: LIGHT DUTY PICKUP TRUCKS AND SPORT UTILITY VEHICLES. SOME OF THESE VEHICLES WERE BUILT WITH INCORRECT PAYLOAD INFORMATION ON THE VEHICLE CERTIFICATION LABEL. THE PAYLOAD SHOWN ON THE LABEL IS GREATER THAN THE MAXIMUM VALIDATED PAYLOAD. IF THE VEHICLE WERE LOADED TO THE INCORRECTLY LABELED PAYLOAD, IT MAY NOT RIDE AND HANDLE IN THE MANNER THAT THE DRIVER EXPECTS.
Consequence & remedy
Consequence: THIS COULD RESULT IN A LOSS OF CONTROL OF THE VEHICLE OR AN INABILITY TO STOP THE VEHICLE WITHIN EXPECTED STOPPING DISTANCES.
Remedy: OWNERS WILL BE SENT A NEW LABEL FOR INSTALLATION ON THE DRIVER'S DOOR OF THE VEHICLE.
Aug 7, 2000
VEHICLE DESCRIPTION: PASSENGER VEHICLES, LIGHT DUTY TRUCKS, SPORT UTILITY VEHICLES, AND MINI VANS EQUIPPED WITH TRW SEAT BELT BUCKLE ASSEMBLIES. THE BUCKLE BASE OF THESE SEAT BELT ASSEMBLIES WERE NOT PROPERLY HEAT TREATED AND THEREFORE DO NOT PASS THE LOAD BEARING REQUIREMENT OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 209, "SEAT BELT ASSEMBLIES."
Consequence & remedy
Consequence: IN THE EVENT OF A VEHICLE CRASH, THE OCCUPANT MAY NOT BE PROPERLY RESTRAINED.
Remedy: DEALERS WILL INSPECT THE VEHICLE'S SAFETY BELT BUCKLE ASSEMBLY DATE CODES AND, IF NECESSARY, WILL REPLACE ANY SAFETY BELT BUCKLE ASSEMBLY.
Feb 28, 2000
VEHICLE DESCRIPTION: LIGHT DUTY PICKUP TRUCKS EQUIPPED WITH 4-WHEEL DISC BRAKES. SOME OF THESE VEHICLES HAVE AN ANTILOCK BRAKE SYSTEM (ABS) MOTOR CONTAINING AN OUT-OF-SPECIFICATION SPRING CLIP. THIS CLIP COULD ALLOW THE MOTOR BEARING TO BECOME MISALIGNED. IF MISALIGNMENT OCCURS, EVENTUALLY THE ABS WOULD BE NON-FUNCTIONAL.
Consequence & remedy
Consequence: THE BASE BRAKES WOULD REMAIN FULLY FUNCTIONAL, BUT THE DYNAMIC REAR PROPORTIONING (DRP) SYSTEM, WHICH OPTIMIZES FRONT TO REAR BRAKE BALANCE, WOULD BECOME INOPERATIVE.
Remedy: DEALERS WILL REPLACE THE BRAKE PRESSURE MODULE VALVE ASSEMBLY.
Aug 11, 1999
VEHICLE DESCRIPTION: S -TRUCKS EQUIPPED WITH 2 WHEEL DRIVE. THESE VEHICLES MAY HAVE HAD THE RIGHT-HAND ANTILOCK BRAKE SYSTEM (ABS) MODULE FEED PIPE AND/OR BRAKE CROSSOVER PIPE TUBE NUTS TIGHTENED WITHOUT SEATING THE PIPE-FLARED-ENDS ENOUGH TO WITHSTAND NORMAL ASSEMBLY AND VEHICLE INPUTS WITHOUT PARTIALLY UNSEATING. THIS DOES NOT COMPLY WITH REQUIREMENTS OF FMVSS NO. 105, "HYDRAULIC SERVICE BRAKE NORMAL, EMERGENCY, AND PARK BRAKING PERFORMANCE."
Consequence & remedy
Consequence: IF THIS OCCURRED, THE SEATING SEAL COULD BE BROKEN DURING VEHICLE ASSEMBLY, OR FROM EARLY ROAD INPUTS OR BRAKE FLUID CYCLING, AND A LEAK COULD OCCUR INCREASING THE BRAKE STOPPING DISTANCE.
Remedy: DEALERS WILL INSPECT THE BRAKE PIPE UNION FOR SIGNS OF BRAKE FLUID, AND IF NECESSARY, INSTALL A NEW BRAKE PIPE UNION.
