Car has consistently just shut off while driving (roughly 30 times in the last year). Been into the dealer no less than 10 times. Had thousands of dollars of valve covers, coils, plugs gaskets, windshield wiper components replaced. No change. Car will still die whenever it feels like it. Lincoln/Ford could care less, and the dealer and field engineers seem tired of seeing my car. Constant movement of brake pedal in rhythm with windshield wipers. Dealer has tried to fix numerous times and the problem is worse now then when they started. Front brake pads rattle. Dealer says it is a known issue and I should just deal with it. Front seat backs fall down. Dealer and Ford blame my kids being in car seats. Never had a problem before they took seats apart to replace faulty seat heater. The transmission is awful. Been reprogrammed 3 times and new servos installed. Still does not shift smoothly, and very erratic. Shifts when it shouldn't and does not shift when it should. Car stalled and activated the alarm horn honking, lights blinking in the middle of an intersection. Car restarted. Next day car had dead battery and would not start. Could not even jump it as there was no power to open trunk and lock cylinder was frozen due to lack of use. Batery in trunk!! wheels had to be balanced 3 times then force balanced to remove excessive vibration. All at my expense had leaky reverse light replaced by dealer now have some piece of a fastener floating around inside the deck lid rattling. Clips for e brake are always broken and apparently 180 bucks to fix.
While driving at 30 mph vehicle shut off without warning. Dealer notified.
