NOW THE CALL WILL GIVE A SIGNAL, RED LETTERS, "DO NOT MOVE CAR" AND THE ENTIRE STRUT SYSTEM WILL STOP WORKING AND THE CAR BODY IS VIRTUALLY SITTING ATOP THE TIRES. THIS AFTER REPLACING THE 2 FRONT STRUTS! THE DEALERSHIP SEEMS TO BE AT A LOSS AND I CAN'T EVEN GET THEM TO RETURN MY CALLS. I DON'T THINK IT IS A STRUT PROBLEM BUT A COMPUTER GLITCH. I DON'T THINK IT WAS NECESSARY TO PAY FOR THE STRUT REPLACEMENT. I WOULD LIKE MY CAR FIXED OR A REFUND.
