Im having same problem bought 19 edge with 10 miles on it drove great up until about 9500 miles or so have About 10,000 now and startin up car after sitting car wont accelerate i hear turbo spinning but car wont accelerate. But after putting it in sports mode for a few and switching back seems to have better response no more lag drove on xpressway no lag nothing seems gets better after u drive for a while. But when u first start it in morning is when it does the bucking and delayed acceleration. Ford told me it could be from goin from regular to premium back to regular could do that just said to stick to just premium or regular dont mix but after reading all these comments i know its not because of that. Cant trade it in owe to much on it so basically just wait till they find a fix i guess
