PRE-ACCIDENT CONDITIONS: DAYLIGHT, RAINING, CAR STOPPED AT RED LIGHT. A FEW MINUTES PRIOR TO ARRIVING AT THE RED LIGHT THE DRIVER'S POWER SEAT MOVED ALL THE WAY FORWARD COMPLETLY ON ITS OWN ACCORD AFTER STOPPING AT THE RED LIGHT I RE-ADJUSTED THE DRIVER'S SEAT AND WHEN THE LIGHT TURNED GREEN I PROCEEDED MAKING A RIGHT TURN IN MY NORMAL "OLD LADY" FASHION. ABOUT 3/4 THROUGH THE 90 DEGREE TURN THE REAR WHEELS LOST TRACTION AND BEGAN TO SLIDE TO THE LEFT. I IMMEDIATELY HIT THE BRAKE AND TURNED THE WHEEL TO THE LEFT. (I SUPPOSE IT IS POSSIBLE THAT I ACCIDENTLY HIT THE CRUISE CONTROL BUTTON LOCATED ON THE WHEEL AT THIS TIME). ANYWAY THE CAR ENGINE CONTIUED TO REV AND THE REAR WHEELS CONTINUED TO SPIN, DRIVING ME INTO A COMPLETE 360 DEGREE TURN, ALL THE TIME WITH MY FOOD HARD ON THE BRAKE PEDAL. WHILE IN THIS SPIN THE REAR OF THE CAR JUMPED A MEDIAN CURB TWICE, CROSSED TWO LANES OF ASPHALT, JUMPED ANOTHER CURB AND FINALLY CRASH INTO A CONCRETE LIGHT POLE. ONLY THEN DID THE CAR STALL AND THE DRIVE WHEELS STOP SPINNING.*AK

CAR STALLS OUT WHILE IN MOTION. HAS HAPPENED TURNING A CORNER, ON A BUMPY ROAD (2" ROAD CONSTRUCTION DROP OFF), AND FOR NO APPARANT REASON. DOES NOT HAPPEN VERY OFTEN, BUT CAN BE VERY DANGEROUS IF IN HEAVY TRAFFIC. 2) WHEN TRYING TO PUT CAR IN REVERSE WHILE STOPPED (COMING OUT OF MY GARAGE OR A PARKING SPACE, FOR EXAMPLE) GEAR SHIFT REFUSES TO GO INTO REVERSE. PUTTING INTO FIRST DOES NOT HELP. I HAVE FOUND THAT LETTING UP ON THE CLUTCH JUST THE RIGHT AMOUNT WILL USUALLY LET IT GO INTO REVERSE. 3) SEATBELTS ARE MUCH TO SENSITIVE. JUST DRIVING DOWN THE ROAD YOU CAN HEAR THEM REPEATEDLY CLICKING, LOCKING AND UNLOCKING. YOU HAVE TO MAKE ANY MOVEMENT VERY SLOWLY OR ELSE YOU WILL BE SNAPPED BACK TO THE SEAT. TURNING TO LOOK OVER YOUR SHOULDER AT TRAFFIC WILL GET YOU LOCKED IN. EXTREMELY DANGEROUS. MUCH SAFER FOR THE DRIVER TO GO WITHOUT USING THE SEATBELT, BECAUSE THEY ARE MORE LIKELY TO CAUSE AN ACCIDENT. *AK

WHEN PARKING, VEHICLE ROLLED BACK WHEN GEARSHIFT IN PARK POSITION. VEHICLE CONTINUED TO ROLL BACK AFTER STOPPING AND PUTTING GEARSHIFT IN DRIVE. AFTER TOW AND REPAIR OWNER TOLD THE CABLE HAD BECOME DISCONNECTED BETWEEN THE GEARSHIFT AND TRANSMISSION. IT WAS REATTACHED AND SECURITY STRAP PUT IN PLACE. DEALER REPORTED NO KNOWLEDGE OF WHY IT BECAME DISCONNECTED.
CONSUMER WAS UNABLE TO CLOSE DRIVER'S SIDE DOOR BECAUSE LATCH WOULDN'T SECURE IT. SAMETHING WAS HAPPENING WITH PASSENGER'S DOOR. ALSO, ALL FOUR WINDOWS WOULD NOT ROLL UP THE RIGHT WAY, BUT INSTEAD, WOULD GO OVER THE TOP. IN ADDITION, AFTER 600 MILES TRANSMISSION FAILED WITHOUT A WARNING. *AK
I HAD A NEW RING AND PINION GEAR INSTALLED. UPON DISASSEMBLY OF THE DIFFERENTIAL IT WAS DISCOVERED THAT THE CARRIER BEARINGS WERE WORN OUT, AND HAD EXPERIENCED EXCESSIVE OVERHEATING. I AM LUCKY IT WAS DISCOVERED BEFORE IT FROZE UP.

Sep 20, 1999
VEHICLE DESCRIPTION: PASSENGER VEHICLES. THE SEAT BELT RETRACTOR MAY HAVE A PIN SHAFT IN THE SWITCHABLE ELR/ALR MECHANISM THAT IS INCORRECTLY FORMED. IN SOME CIRCUMSTANCES, THE SWITCHING MECHANISM COULD BECOME NONFUNCTIONAL, PREVENTING THE SEAT BELT WEBBING FROM BEING EXTRACTED FROM THE RETRACTOR. IT IS ALSO POSSIBLE THAT MALFUNCTION OF THE MECHANISM COULD PREVENT THE BELT FROM BEING SWITCHED INTO THE ALR MODE. THE ELR MECHANISM IS NOT AFFECTED BY THIS CONDITION.
Consequence & remedy
Consequence: IF THE MECHANISM MALFUNCTIONS AND DOES NOT ALLOW THE WEBBING TO BE EXTRACTED, THE LAP AND SHOULDER BELT COULD NOT BE WORN BY A VEHICLE OCCUPANT. IN THE EVENT THAT THE MECHANISM DOES NOT ALLOW THE ALR MODE TO BE ENGAGED, THE OPERATOR MAY BE UNABLE TO PROPERLY INSTALL A CHILD SEAT IN THAT SEATING POSITION.
Remedy: DEALERS WILL INSPECT THE LAP AND SHOULDER BELT ASSEMBLIES. ASSEMBLIES WITH JULIAN DATE CODES OF 200 THROUGH 223 ARE SUSPECT AND WILL BE REPLACED.
