PASSENGER AND DRIVER SEATS IN MY 2000 GMC SONOMA HAVE SEAT POSITIONING CONTROLS AND LOCKING MECHANISIMS THAT DO NOT ALWAYS LOCK PROPERLY AND/OR GET JAMMED UP AND HAVE BROKEN. A FRIEND WAS SITTING IN THE PASSENGER SEAT AND IT FAILED TO LOCK INTO PLACE TO KEEP IT FROM SLIDING FORWARD. I ADJUSTED THE BOLTS THAT FASTEN THE SEAT TO THE FLOOR OF THE VEHICLE TO HELP 'REALIGN' THE SEAT FRAME SO THAT THE MECHANISM THAT KEEPS THE SEAT FROM SIDING FRONT AND BACK WOULD KEEP THE SEAT LOCKED INTO POSITION ONCE THE SEATING DISTANCE IS SET. ALSO, THE RECLINING HANDLE ON THE PASSENGER SIDE BROKE OFF, NOT ALLOWING FOR SEAT BACK SUPPORT ANGLE ADJUSTMENT ON THE PASSENGER SIDE. THE DRIVER'S SIDE SEAT BACK SUPPORT ADJUSTMENT LEVER OFTEN 'STICKS' OR 'LOCKS' INTO POSITION....NOT ALLOWING FOR SEAT BACK REST ADJUSTMENT. REAR DIFFERENTIAL SOMETIMES LOCKS UP AND OR SLIPS AND SHAKES AND MAKES NOISE...ESPECIALLY WHEN SIDEWAYS FORCE IS APPLIED...SUCH AS WHEN TURNING IN A CURVE OR CIRCULAR FASHION WITH THE VEHICLE IN MOTION. BOTH TAILGATE SUPPORT CABLES BROKE ON THE TRUCK. FRONT DRIVER'S SIDE BEARING HAD EXCESS WEAR AND HAD TO BE REPLACED AT 65 000 KM. DRIVER'S SIDE WIPER ARM GOT DISLODGED FROM THE SHAFT THAT TURNS IT AND WAS KNOCKED OUT OF POSITION ON 2 OCCASIONS. POWER STEERING FAILS FOR SHORT INTERMITTENT PERIODS WHEN THE VEHICLE IS FIRST STARTED FROM A 'COLD' AND 'WARM' STATE AND THE STEERING BECOMES STIFFER AND LESS RESPONSIVE. MOST NOTICABLE AT SLOWER VEHICLE SPEEDS.

TRANSMISSION SOMETIMES WILL ACCELERATE WITHOUT A PRIOR WARNING, AND SOMETIMES WILL NOT WORK WHILE STEPPING ON FUEL PEDAL.*AK THE CAUSE FOR THE TRANSMISSION MALFUNCTIONING WAS FOUND TO BE THE MAIN BOLT THAT HOLDS TRANSMISSION DOWN WHICH WAS LOOSE. *YH

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.
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.
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.
