AS I APPROACHED A STREET FROM A STORE PARKING LOT, I STEPPED ON THE BRAKE BUT THE CAR DID NOT SLOW. AS I SAW I WAS NOT GOING TO STOP, I TRIED TO STEER THE CAR TO THE RIGHT TO TRY TO AVOID CROSSING INTO TRAFFIC. THE STEERING WHEEL WOULD NOT TURN. I WAS GOING VERY SLOWLY AND SAW THE FACE OF THE DRIVER OF THE CAR THAT HIT ME. THAT CAR HIT MY CAR TWICE. ONCE IN THE FRONT LEFT CORNER AND THEN IN LEFT REAR CORNER, AS MY CAR SPUN 90 DEGREES TO THE RIGHT FROM THE FIRST IMPACT. SOMEONE ASKED ME IF MY CAR HAD TURNED OFF. I SAID I DIDN'T KNOW BECAUSE THE ENGINE IS SO QUIET. A RESPONDING SHERIFF'S DEPUTY TOLD MY HUSBAND THE DRIVER WHO HIT ME SAID HE SAW ME LOOKING AT HIM AND WAS SURE I WAS GOING TO STOP. LATER ANALYSIS BY A CADILLAC TECHNICIAN REVEALED ERROR CODES FROM THE FRONT WHEEL SPEED SENSORS. I HAVE BEEN TOLD A WHEEL SPEED SENSOR MALFUNCTION CAN AFFECT BRAKING. *TR
