2000 MERCEDES BENZ ML430 Traction Control System Problems

I OWN A 2000 MERCEDES BENZ ML 430, ON 07/12/10, 07/15/10, 07/23/10, 07/25/10, 07/28/10 AND 07/29/10 WHILE DRIVING MY VEHICLE AT APPROXIMATELY 40 MPH THE VEHICLE CAME TO AN ABRUPT AND COMPLETE STOP WITHOUT PRESSURE BEING APPLIED TO THE BRAKE PEDAL. THE VEHCILE WOULD BRAKE-SKID-BRAKE-SKID THIS LASTED FOR APPROXIMATELY ONE MINUTE; THEN THE BAS/ESP AND EST LIGHTS WOULD ILLUMINATE ON MY DASHBOARD, THE VEHICLE WOULD THEN BE DRIVEABLE WHILE THESE LIGHTS WERE ON, ONCE THESE LIGHTS WENT OFF THE VEHICLE WOULD START BRAKING & SKIDDING AGAIN. I REPORTED THIS TO NHTSA ON 07/30/10 UNDER CASE #10346283. ON OR ABOUT 08/20/10, MERCEDES BENZ OF USA TOOK RESPONSIBILITY FOR THE MALFUNCTION & ASKED THAT THE VEHICLE BE TAKEN TO MERCEDES BENZ OF MIAMI. THE VEHICLE WAS REPAIRED ON 08/24/2010. SINCE THAT TIME, THE VEHICLE HAS BEEN TAKEN BACK TO MERCEDES BENZ OF MIAMI APPROXIMATELY 4 OR 5 TIMES FOR THE SAME PROBLEM....

1. ACCELERATION AND LANE CHANGING ON THE FREEWAY AT AROUND 65 MPH 2. THE TRACTION CONTROL STARTS BUGGING OUT AND THE CAR STARTS FRANTICALLY PUMPING THE BRAKES FROM WHEEL TO WHEEL TRYING TO FIND TRACTION, TRACTION CONTROL LIGHT LIGHTS UP ON DASH. LASTS FOR ABOUT 2-4 SECONDS, VERY SCARY. 3. NO REPAIRS DONE YET. *TR
