WHEN THE CRUISE CONTROL IS ACTIVATED, THE CAR WILL SUDDENLY ACCELERATE TO HIGH SPEED BY ITSELF AND THE BRAKE DOES NOT WORK. THE ONLY OPTION IS TO SHIFT TO "NEUTRAL"AND APPLY THE BRAKES OR SWITCH -OFF THE ENGINE. IT IS MOST DANGEROUS WHEN YOU ARE IN HEAVY TRAFFIC. *JB
PARKED VEHICLE IN FRONT OF GARAGE. TURNED OFF ENGINE, GOT OUT & DECIDED TO MOVE CAR CLOSER TO GARAGE. PUT ON SEAT BELT, RESTARTED CAR, PUT FOOT ON BRAKE, & SHIFTED INTO DRIVE. VEHICLE TOOK OFF LIKE A ROCKET, SMASHED THROUGH GARAGE DOOR, THROUGH STRUCTURAL BEAMS & OUT THE SIDE OF THE BUILDING LANDING ON THE GROUND WITH FRONT OF CAR. ENGINE WAS STILL ROARING & I WAS ABLE TO TURN OFF THE IGNITION & OPEN THE PASSENGER DOOR TO GET OUT. *TR
IN 1993 I HAD A PROBLEM WITH THE VEHICLE ENGINE SHUTING DOWN WHILE DRIVING IF AT ANY SPEED. I WOULD STEP ON THE GAS AND THE VEHICLE HAD NO POWER. IT WOULD RESTART AND I COULD PROCEED. IT WAS VERY DANGEROUS AND SOMETIMES I WAS MAKING A LEFT TURN AND ONCOMING TRAFFIC WAS APPROACHING. THE VEHICLE WAS UNDER WARRANTY BY MERCEDES-BENZ AND I TOOK IT IN. THEY REPLACED THE INGNITION CONTROL MODULE AND OVERLOAD PROTECTION RELAY. IN JULY 2000, I HAD THE ENGINE SHUTTING DOWN AGAIN. IT WAS VERY INTERMITTEN BUT FINALLY I HAD IT TOWED TO THE DEALER IN NASHVIL…

CAR: 1984 MERCEDES 380SL I WAS PULLING INTO MY DRIVEWAY WHEN I HEARD A CLUNK. I KEPT DRIVING INTO MY CARPORT (GARAGE), AND I LOOKED UNDERNEATH TO SEE IF I COULD SEE ANYTHING. I HAD SOMEONE ELSE LOOK AT IT, AND WE DISCOVERED THAT THE SUBFRAME THAT HOLDS THE LOWER A-ARM WAS BROKEN, AND THE A-ARM HANGING BY ONLY ONE END.
