2007 Ford Mustang V6 Premium 2dr Coupe (4.0L 6cyl 5M)
High erratic idle (2500 RPM). Dealer cannot fix after 7 tries to repair. Also low fuel economy (20 mpg in V6), rough shifting (especially from 2nd to 3rd and sometimes won’t go into reverse), bad radio, and many rattles. Terrible service – no wonder Ford is in trouble now. They build lemons and do not take any responsibility to fix the problems.
