Brakes release when stopped on slope (Powerboost)

[AllFordTech]

I saw another thread where someone was saying TSB 21-2407 seem to take care of the issue. I still have not had any complaints at the dealer I work at about this issue. I would say this TSB could be what you guys are experiencing

My 2022 Powerboost did this twice today on my way home from work. Felt like someone bumped into the back of me the first time. Did it again at the next stop light. Do we know how to fix this issue? Do I need to take it to the dealership?

You describe the symptoms of a failing auxiliary (electric) transmission pump.

Hi there, I'd be happy to look into your F-150 concerns on my end. Will you send us a message with your VIN and dealership info? I can look into things on my end.

Same thing happening today. I’ll have to take it in. Very very annoying.
