Unintended sudden acceleration while stepping on brakes on my 2006 Ford F150. This has happened to me on several occasions, the last being this year in June. I stepped on the brakes to slow down as there was a truck in front of me and when I did, instead of slowing down the truck accelerated on me. I shifted the gears from Drive to Park in order to stop the truck from moving. This is what I had done in the past. I'm sure that is not good for my transmission.

Prior to that, the last time I had the sudden acceleration problem was approximately 4 to 5 years ago. I took the truck to the Ford dealership and was told they had no idea what I was talking about. They checked it out, drove the truck and said they had no problems. The problem seems to be that this issue with the sudden acceleration is a random occurrence. The truck is 9 years old and has approximately 74,000 miles. Any suggestions on "repairing" the problem?

For the 4th time since I've owned my f150 (and the 4th time since I've been driving, which spans 43 years) I hit my brake lightly at low speed and the truck accelerated. This is not an illusion caused by a wet or icy road, nor by wet or otherwise nonfunctional brakes. Nor is it a case of hitting the accelerator simultaneously (I tried that as an experiment; it's almost impossible for me to do it even if I try). The truck lurches forward, and seems to come out of it when I pump and/or stand on the brake pedal. Sorry for not posting the first 3 incidents; I didn't want to complain about my own dumb mistakes, but I'm convinced now it wasn't my fat foot. BTW I have 20+ years' experience as an embedded s/w engineer (I'm a patent holder) and I know that computer-aided devices not only can but regularly do make mistakes, even if only for the reason that they are poorly programmed. Automated testing never ever finds all the bugs, especially intermittent ones.
