IllustrationWHEN DRIVING AT NORMAL SPEED THE FRONT PASSENGER SIDE WHEEL LOCKS UP. THIS HAS HAPPENED AT 40 MPH (IN TOWN) AND ALSO 65 MPH (ON HIGHWAY), ALMOST CAUSING ME TO HIT ANOTHER CAR AND RUN OFF THE ROAD. ITS HAPPENS TWICE FOR ONLY 3 SECONDS AT A TIME. THE BAS, SAP AND EMERGENCY LIGHTS ALL COME ON AT THIS TIME.
2003 MERCEDES-BENZ SLK230
