NHTSA Complaint #10330616 — 2002 MERCEDES BENZ ML320

[MERCEDES BENZ ML 320 2002] WHILE DRIVING EAST ON ROUTE 80 AT 65 MPH AND APPROACHING THE TOLL BOOTHS OF THE GEORGE WASHINGTON BRIDGE, I TAPPED MY BRAKES TO DISENGAGE MY SPEED CONTROL. THE SPEED CONTROL DID NOT SHUT DOWN. I HIT THE BRAKE PEDAL SEVERAL MORE TIMES HARDER AND HARDER, BUT THE SPEED CONTROL STAYED IN CONTROL. I PUSHED DOWN VERY HARD ON THE BRAKE PEDAL WITH BOTH FEET AND ALTHOUGH THE CAR SLOWED A LITTLE, THE SPEED CONTROL DRAMATICALLY SPEEDED UP THE ENGINE WITH THE TACHOMETER GOING ALMOST FULL SCALE. I WAS ABLE TO REDUCE THE CAR'S SPEED FROM ABOUT 65 TO UNDER 50 MPH, BUT WAS STILL PRETTY SCARED. THIS WAS A TERRIFYING EXPERIENCE AND AS AN ENGINEER I REALIZED MY OPTIONS AND TIME TO REACT WERE VERY LIMITED! I FIGURED MY CHOICES WERE FEW: 1) BRAKE UNTIL THE CAR EITHER STOPPED OR I HAD HIT THE STOPPED CARS AT THE TOLL BOOTHS (MAYBE DAMAGE THE TRANSMISSION FURTHER), 2) SHIFT THE CAR INTO NEUTRAL HOPING THAT EITHER THE SPEED CONTROL WOULD DISENGAGE OR AT LEAST I COULD STOP THE CAR (ENGINE RPMS MIGHT RUN AWAY AND DESTROY THE ENGINE), OR 3) TRY TO SHUT OFF THE SPEED CONTROL WITH THE CONTROL STALK ON THE LEFT OF THE STEERING COLUMN (WHICH I OBVIOUSLY COULD NOT READ CLOSELY TO FIGURE OUT WHERE THE STOP MIGHT BE). FORTUNATELY, WITH SEVERAL TRIES I WAS ABLE TO FIND THE STOP POSITION ON THE SPEED CONTROL STALK AND DISENGAGE THE CONTROL. I BRAKED VERY HARD TO STOP SHORT OF A COLLISION..... AND GOT HARSH WORDS AND LOOKS FROM THE ADJACENT TOLL COLLECTORS. I SUSPECTED THAT THE BRAKE LIGHT SWITCH WAS NOT WORKING AND THIS WAS CONFIRMED BY MY MECHANIC (EDDIE RODRIGUEZ OF EDDY'S TOTAL AUTO CARE). THE MECHANIC ALSO HAS TO REPLACE THE BRAKE PRESSURE SENSOR. MY WIFE IS INSISTING THAT I GET RID OF THE CAR IMMEDIATELY AND BUY A NEW CAR. I LOVE MY ML 320..... BUT I LOVE MY WIFE TOO! *TR
