My Edge has 9,800 miles on it and had to have its engine ( long block replaced at 4,000 miles. Since the new Engine was installed I have had my check engine light come on twice going up hill. It flashed for about a minute or so and one time even lost power. Dealership says nothing is coming up on the diagnostic machine. Also has a hight pitch squeal when making sharp left turns. Dealer just told me its normal in some Fords?? wth?? Any help?
