THE BRAKING SYSTEM STARTS TO SHAKE AND VIBRATE AS IF DRIVING ON COBBLESTONE ROAD THEN BRAKING SYSTEM SHAKES VIOLENTLY FROM FRONT OF CAR THIS PROBLEM SEEMS TO HAPPEN ONLY WHEN TEMPS ARE VERY HIGH IN THE 100 DEGREE RANGE AS WE GO TO THE DESERT OFTEN. THIS HAPPENS SEVERAL TIMES A YEAR. THE VIBRATIONS START AS WE ARE DRIVING AND YOU CAN FEEL THE FRONT END START TO VIBRATETHE GETS WORSE, IF THE BRAKES ARE APPLIED WHEN THIS IS SHAKING THE WHOLE CAR SHAKES VOILENTLYAND IS HARD TO STOP ALMOST MAKES THE CAR OUT OF CONTROL. THIS CAN GO ON FOR AS LONG AS 45 MINS TO AN HOUR AS WE DRIVE DOWNTHE ROAD OR FREEWAY. THEN IT JUSST STOPS SHAKIN AND DOES NOT AHPPEN AGAIN FOR A FEW DAYS , BUT IF WE ARE STILL IN THE HEAT IT WIL HAPPEN AGAIN. WHEN WE GET HOME AND GOTO THE DEALER THEY CANNOT FEEL THE PROBLEM SO THEY SAY THERE IS NO PROBLEM MY WIFE AND CHILDREN ARE AFFRAID TO RIDE IN THE CAR WHEN WE GO ON TRIPS NOW. THIS PROBLEM MUST BE FIXED. I LOVE THIS CAR AND IT SUITS MY NEEDS BUT THIS HAS TO BE FIXED.*AK
