Chevrolet Uplander LS2005

THE BRAUN CORPORATION HAS NOTIFIED NHTSA ABOUT A DEFECT IN CERTAIN MODEL YEAR 2005-2008 GENERAL MOTORS MOBILITY CONVERSION, HANDICAPPED ACCESSIBLE LOW FLOOR MINIVANS. DURING CONVERSION, THE DRIVER OR PASSENGER SIDE TRAILING ARM MODIFICATION MAY NOT HAVE BEEN ADEQUATELY WELDED.

A SQUEAKING OR CLUNKING NOISE MAY DEVELOP. THE TRAILING ARM BUSHINGS MAY PREMATURELY WEAR AND THE TRAILING ARM MAY FRACTURE OR SEPARATE, ALLOWING THE REAR AXLE TO BECOME PARTIALLY SEPARATED FROM THE CHASSIS INCREASING THE RISK OF A CRASH.

CERTAIN SPORT UTILITY VEHICLES FAIL TO CONFORM TO THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 135, 'PASSENGER CAR BRAKE SYSTEMS.' TO MEET THE STANDARD, THE VEHICLE MUST NOT MOVE FOR FIVE MINUTES WHEN STOPPED ON A STEEP HILL WITH THE PARKING BRAKE APPLIED AND THE VEHICLE IN NEUTRAL (N). SOME OF THESE VEHICLES FAILED THIS TEST.

WHEN THE PARKING BRAKE IS RELEASED, THE DRIVER MAY NOTICE UNINTENDED BRAKING WHEN ACCELERATING, DECELERATING, OR COASTING, AND A NOISE COMING FROM THE REAR OF THE VEHICLE. UNINTENDED VEHICLE MOVEMENT COULD OCCUR INCREASING THE RISK OF A CRASH.

ON CERTAIN MINIVANS, THE OUTBOARD RELEASE HANDLE ON THE IMPACT-SIDE SECOND-ROW BUCKET SEAT MAY BE ACTUATED AND THE REAR LATCHES MAY UNLATCH EARLY IN A SIDE IMPACT CRASH. THIS WAS DISCOVERED IN A SIDE IMPACT TEST RUN BY GM, UNDER CONDITIONS SIMILAR TO NHTSA'S NEW CAR ASSESSMENT PROGRAM (NCAP) SIDE IMPACT TEST.

IF THE REAR LATCHES OF THE SEAT RELEASE EARLY IN A SEVERE SIDE IMPACT, THE FRONT OUTBOARD LATCH MAY DISENGAGE AND INCREASE THE POTENTIAL FOR INJURY TO THE OCCUPANT OF THE SEAT.
