While entering onto the woodrow wilson bridge from I-295s on 2/1/2018, I pulled into the center lane and backed off the gas pedal, but the car continued to accelerate on its own. Luckily the traffic was light, after hitting the brake and the off button for the cruise control, to no effect, I was able to pull into the right lane and turn the car off. While still in motion, I turned the key back on and everything was normal again. Since it wasn't a cruise control issue, it would appear it is similar to the toyota problem with the drive by wire issue.

Sporadically and without warning, my cruise control will activate causing the vehicle to immediately accelerate. I had been using the control but had de-activated it but depressing the brake which leaves the unit "on" but not activated.
Was getting on highway, accelerated more than normal to pass a very slow vehicle entering highway from 5 MPH on highway (estimate 80 to 90% of full throttle), when I was safe of slow vehicle and let off the pedal, vehicle continued to accelerate to about 83 MPH as I recall, I continued to press brake, still accelerating, pressed steering control buttons to make sure cruise control was off (did not have it on previous to this), pressed brakes again and again, finally vehicle slowed down just before I was going to turn of the ignition. Did not have the car checked out, did not smell or see anything irregular, vehicle increase in the continued speed was felt with some g-force before it went back to normal operation. Appears that it just went full throttle on its own I could feel it really moving. Has only occurred once, I also emailed ford regarding this issue. Luckily it was 5 a.m. In the morning no harm done, just frightened. Bought car used @ 45 k incident occurred around 47,393 miles.
