When slowing down the truck lurches forward when going back into electric and/or gas mode, and has nearly caused my truck to collide with the vehicle in front of me. The truck will pick up speed when slowing down, as when downshifting and switching out/in electric to gas mode it propels the truck forward even while firmly pressing the brake.
On several occasions while waiting in an intersection to make a left turn, the vehicle loses power or something. I can put the pedal to the floor and I get no response from the vehicle. Eventually after stepping on gas the truck seems to reimage and go. The only problem is I have nearly been T-Boned thinking I will have the power to make a left turn before oncoming traffic gets to me. I suspect it has something to do with the electrical power is trying to switch to engine power and something is failing. I have no confidence in this truck anymore.
I had my vehicle on cruise control set at 76mph I switched lanes to pass another vehicle and while still on cruise control I sped my truck to approx. 80mph to pass and after doing that my truck kept accelerating on its own. It reached a speed of 90mph during this time I was pushing on the brakes which did slow the truck but as soon as I would let go it would accelerate back up. After about 15 - 20 seconds it finally stopped doing it and the truck worked fine afterwards. I tried to reproduce the action but it did not do it again.
When towing a trailer with trailer brakes, the trailer brakes are tested and confirmed to be working at the beginning of the journey, but at some point during the journey, the trailer brakes will stop working with no indication compromising my stopping ability. This issues has occurred multiple time and can confirm there are no problems with the trailer brakes themselves. This same issue is being reported by multiple other 2021 F150 owners.
