2011 V6 3.7L Ford Mustang Produced in June 2010 Purchased Late August 2010 (needed a car at that point, couldn't wait for another model year) 21500K miles when problems started Purchased Extended Warranty Symptoms: - Throwing Camshaft Sensor Failing Code => Dealer replaced sensor part, but never double checked for another issue...picked the car up with Check Engine Light STILL ON. (Yes, my mistake, had my reasons at the time!) One Week Later - FULL SHUDDER upon starting up. - CLANKING, THUDDING sounds from the left side of the engine compartment (Not Ticks). (Immediate shut her down and called Ford Roadside Assistance) She was at the dealership's service department Monday of last week. The technician said something was loose in the Motor and that it is a manufacturer's defect. They suspect that a valve dropped. That was Tuesday's report. It took until TODAY to get a heavy engine mechanic to work on her. So...not sure what to do. I have my rental...HATE it (Chevy Aveo). I miss my mustang. Why does it take the dealerships SO LONG to get their booties in gear?! What do you guys think? I wanted to fill you in. Not going to take the car until she's running the way she's supposed to.
