I just bought an 08 F150 xlt super crew 4x4 from a dealer with 96,000 miles on it. I've put roughly 300 miles on it so far, and on 3 different instances when Ive hit the brakes, it has acted as though I had the gas peddle at about half throttle with the brakes still trying to work. At first, I figured I was accidentally hitting the gas and brake at the same time, but the last time I completely removed my right foot from the brake pedal and pressed it on the far left with my left foot and the problem persisted for about 2-3 seconds. The dealer is going to look at it tomorrow, but I'm not sure how much they'll figure out if it wont do it while they're driving it. Has anyone had a common issue, if so, how did you fix it?
