2001 Mercedes Benz SLK230

WHILE DRIVING ON AN INTERSTATE HIGHWAY IN WET CONDITIONS (RAINING ON AND OFF), MY CAR SUDDENLY JERKED TO THE RIGHT; IT FELT AS IF MY RIGHT REAR WHEEL BRAKES HAD APPLIED FOR A SECOND OR SO. I NOTICED THAT THE YELLOW TRIANGLE IN THE MIDDLE OF THE DASH BOARD THAT ALERTS ME TO THE APPLICATION OF THE ESC WAS BLINKING (AND CONTINUED TO BLINK UNTIL I STOPPED THE CAR AND TURNED OFF THE ENGINE). AS I RECALL, MY CAR WENT INTO THE LANE TO MY RIGHT BEFORE I REGAINED CONTROL. I HAD BOTH HANDS ON THE WHEEL AT THE TIME. BECAUSE OF THE WET CONDITIONS, I ASSUMED I MAY HAVE SKIDDED WITHOUT MY REALIZING IT, CAUSING THE ESC TO KICK IN. WHEN I GOT OFF THE HIGHWAY AT THE NEXT OPPORTUNITY, I TURNED OFF THE MOTOR AND GOT OUT. UPON RESTARTING THE CAR, THE ESC LIGHT HAD GONE OUT, AND I ASSUMED EVERYTHING WAS OKAY. BUT THE SAME THING HAPPENED AGAIN BEFORE I GOT TO MY DESTINATION (PITTSBURGH). I CALLED A LOCAL DEALER, WHO ADVISED ME IT MIGHT BE A DEFECTIVE SENSOR AND THAT IT SHOULD BE OKAY TO MAKE THE RETURN DRIVE TO NO. VIRGINIA BEFORE GETTING THE VEHICLE FIXED. I HAD THE SAME PROBLEM A FEW TIMES ON THE RETURN TRIP AND THEN BROUGHT THE CAR INTO MY DEALER. THE DEALER SERVICE FORM IDENTIFIED THE PROBLEM AS "NECESSARY TO REPLACE THE YAW RATE SENSOR." THE REPAIR CHARGE WAS $807.85. *TR
