Cant use breaks, everything is dead! Cant steer nothing. Could have been killed. This has happened before twice. Now I'm afraid to drive my car if this happens when im on the freeway, thats a problem, endangering me and everyone around. This is nuts because I pride myself on keeping my car in tip top shape always and this is undetectable .
