Report Date:
November 15, 1999
Campaign Number:
99V063001
Component:
AIR BAGS:SIDE/WINDOW

Summary:
VEHICLE DESCRIPTION: PASSENGER VEHICLES. THESE VEHICLES ARE BUILT WITH A SIDE AIR BAG SYSTEM CONSISTING OF DOOR-MOUNTED THORAX AIR BAGS (REAR DOOR AIR BAGS ARE OPTIONAL), A CENTRAL ELECTRONIC SENSOR AND DIAGNOSTIC SYSTEM, LEFT AND RIGHT SATELLITE IMPACT SENSORS, AND ASSOCIATED WIRING. THIS SYSTEM IS UNDULY SENSITIVE TO CERTAIN NON-CRASH IMPACTS, SUCH AS CONTACTING LARGE POTHOLES OR CURBS AT SUBSTANTIAL SPEED.

Consequence Summary:
THIS COULD CAUSE THE SIDE AIR BAG TO DEPLOY WITHOUT AN ACTUAL SIDE CRASH. IN ADDITION, THE BATTERY SAFETY TERMINAL (BST) COULD ALSO ACTIVATE, DISCONNECTING THE STARTER CABLE FROM THE BATTERY. IN THIS CASE, THE VEHICLE'S ELECTRICAL SYSTEM COULD CONTINUE TO OPERATE AND THE ENGINE WOULD CONTINUE TO RUN, BUT AFTER STOPPING, COULD NOT BE RESTARTED.

Corrective Summary:
DEALERS WILL REPROGRAM THE CENTRAL COMPUTER CONTROL MODULE THAT REGULATES THE PERFORMANCE OF ALL OF THE VEHICLE'S OCCUPANT PROTECTION SYSTEMS.

Report Date:

Campaign Number:
97V131000
Component:
VEHICLE SPEED CONTROL

Summary:
THE CRUISE CONTROL AND THROTTLE CABLES ARE ATTACHED TO THE SAME THROTTLE VALVE ACTUATING LEVER AT THE THROTTLE HOUSING. IT IS POSSIBLE THAT THE PLASTIC BUSHING ON EITHER CABLE COULD BREAK DUE TO ENVIRONMENTAL INFLUENCES COUPLED WITH VIBRATION. IF THE BUSHING BREAKS, THE OUTER CABLE HOUSING CAN SEPARATE FROM THE BUSHING. IN THIS CASE, DURING APPLICATION OF THE THROTTLE PEDAL WITHOUT CRUISE CONTROL BEING ENGAGED, THE OUTER TUBE COULD CATCH ON THE EDGE OF THE BROKEN BUSHING.

Consequence Summary:
THIS COULD CAUSE THE THROTTLE VALVE TO REMAIN PARTIALLY OPEN. IT HIS WERE TO OCCUR, THE CAR MIGHT NOT DECELERATE AS EXPECTED INCREASING THE RISK OF A VEHICLE CRASH.

Corrective Summary:
DEALERS WILL INSTALL A SPRING STEEL CLIP ON THE OUTER TUBE OF EACH CABLE IN THE AREA OF THE ADJUSTING SCREW AND PLASTIC BUSHING. THE CLIP IS DESIGNED TO PREVENT THE OUTER TUBE FROM DISLODGING FROM THE BUSHING.
