NHTSA Complaint #11035778 — 2001 MERCEDES BENZ ML430

RE: 2001 MB ML430 ELECTRONIC BRAKING SENSOR THE FRONT PASSENGER BRAKE INITIALLY LOCKED UP AT LOW SPEED UPON ACCELERATION. AFTER STOPPING AND TURNING THE VEHICLE OFF AND BACK ON THE SYSTEM WAS BACK TO NORMAL. THEN ONE DAY I WAS TRAVELING AT NEAR 70 MPH IN THE PASSING LANE OF AN INTERSTATE HIGHWAY WHEN THE FRONT DRIVER BRAKE LOCKED UP AND BRAKE TIRE SMOKE BILLOWED FROM MY VEHICLE WHICH CAUSED TRAFFIC BEHIND ME TO SWERVE AND BRAKE BEHIND AND ON THE SIDE OF ME. I PROCEEDED TO PULL OFF ONTO THE SHOULDER OF THE HIGHWAY AND TURNED MY VEHICLE OFF AND BACK ON, AFTER WHICH MY VEHICLE OPERATED NORMALLY. I PROCEEDED TO DO AN ONLINE SEARCH AND LEARNED THAT THIS WAS A COMMON SORT OF PROBLEM FOR THIS MODEL.. PARTICULARLY AT LOW SPEEDS. IN MY CASE IT HAPPENED AT LOW SPEEDS AND THEN THE ONE TIME AT 70 MPH. I LEARNED THAT THE YAW SENSOR WHICH IS PART OF THE ABS SYSTEM WAS COMMONLY REPORTED AS THE LIKELY CAUSE OF THE PROBLEM.. I PROCEEDED TO DISCONNECT THE YAW SENSOR AND HAVE HAD NO FURTHER PROBLEMS. I AM FORTUNATE THAT IT WAS NOT A RAINY DAY, OTHERWISE THE RESULTS MAY HAVE BEEN CATASTROPHIC WITH SO MANY VEHICLES BEHIND ME AND TRAVELING AT SUCH A HIGH SPEED.
