2009 SE Sedan (new); transmission failed @ 7,000 miles. Dealer fixed under warranty, problem resurfaced @ 10,500 miles.
Grunching sound when tranny upshifted or downshifted. Tranny would shift by itself to first gear when cruising about 50. Slammed my wife and I forward violently more than once. It also intermittently would not shift down @ uphill stop signs. Would sometimes take several seconds to shift down after stopped!
Sync locked-up (firmware) @ same time as first transmission repair. Saved changes did not change anything; voice prompts turned-off did nothing. Sync updates netted failed update message/voice.
I turned the above vehicle back-in to the dealer at a loss, as I couldn't have a brand new vehicle that had ongoing issues, and could/would break down at any time.
I purchased a 2010 SES Sedan, loaded, in its place, as I wanted to give Ford one more chance, but if this vehicle suffers any issues, my hard-earned money will go elsewhere.
