Why would the front wheels on a front wheel drive ford fusion quit turning? We pulled out of the driveway started down the road got to about 25 miles an hour and the car coasted to a stop - the engine kept running but the car would not move. By the time the tow truck arrived the wheels would turn about a 1/4 of the way and then not turn at all then turn a bout a 1/4 of the way and then not at all. What is the problem?
