I was driving my wife's 2013 sel awd. Went to hit the brakes and there was no assist. There was also absolutely no indication of an issue related to me by any warning light, buzzer, just all of a sudden I am not able to stop and I overshoot a turn by 100 ft. Luckily I was out in the country at the time. Had I been in heavy traffic, things would of been very different. I see the f150 had a recall because of the vacuum pump failure. Cannot believe that I was given no warning. Now it is at the dealer and of course it isn't under warranty. Car has 64000 miles, has been nothing but problems, $1500.00 later, I should have it back this Friday . I love my Mustang GT, have always been a Ford man. I believe this car is headed for the trade in at some Japanese car dealer. My wife deserves better and more reliable.
