WARRANTY ISSUES AND/OR MANUFACTURING DEFECTS THAT SHOULD BE COVERED BY WARRANTY. *PH AT THE FIRST 10,000 MILES, THE CONSUMER NOTICED BRAKE TRAVEL WAS TOO LONG AND WAS ADVISED BY AN SERVICE ADVISOR THAT THIS WAS NORMAL.

I OWN A 2002 MERCEDES BENZ ML500. A WEEK AGO I EXPERIENCED SUDDEN ACCELERATION WHILE DRIVING ON AN INTERSTATE. AS I WAS ACCELERATING THE CAR SUDDENLY ACCELERATED (THE GAS PEDAL WENT TO THE FLOOR) AND I WAS UNABLE TO STOP THE CAR DESPITE FULLY DEPRESSING THE BREAK PEDAL. THE CAR REACHED 80+ MPH AND I WAS FORCED TO DRIVE OFF OF THE ROAD TO AVOID AN ACCIDENT (I WAS ABLE TO SLOW IT TO ABOUT 50 MPH BY FULLY DEPRESSING THE BREAK PEDAL). I WAS FINALLY ABLE TO STOP THE CAR BY SHIFTING INTO NEUTRAL (IT HAS AN AUTOMATIC TRANSMISSION; WHEN I SHIFTED T…
