I OWN A 2003 MERCEDES SLK 230 , WHICH BRAKES ON IT'S OWN AT ALL DIFFERENT SPEEDS . AFTER THE CAR BRAKES TO THE RIGHT FOR A COUPLE OF SECOND THE BAS/ESP LIGHT COMES ON . I HAVE HAD THIS HAPPEN ON THE HIGHWAY AT 60 MPH (VERY SCARY). I HAVE SINCE HAD THE BRAKE SWITCH CHANGED , AND WHEEL SENSORS AND NEW BATTERY. I HAVE SINCE PICKED MY CAR UP AND NO PROBLEM FOR THE LAST 100 MILES UNTIL TODAY WHEN THE SAME THING OCCURRED AT A LOWER SPEED . CAR IS BACK IN THE SHOP READING NO CODES !!!!!! I HAVE GONE TO THE MERCEDES FORUM AND I FIND THAT THIS PROBLEM IS NOT UNCOMMON . IT SEEMS THAT THE YAW SENSOR AND OR LATERAL CONTROL SENSOR GOES AND CAUSE THE CAR TO THINK IT IS SLIDING AND RANDOMLY BRAKES (ALWAYS TO THE RIGHT) . ALL OF THE COMPLAINTS HAVE HAD THEIR OWNERS IN A PANIC . THIS SEEMS TO BE EXTREMELY DANGEROUS . *TR
