2021 Ford Bronco Sport Vehicle speed control Problems

“Car was put into drive and wouldn’t go. It would finally go but Everytime the engine changed gears it dropped to 0 rpm’s making it very dangerous to drive!!! Lots of lights came on and my app sent me two things wrong with it. After having it checked the codes said it was a valve body issue. Replacing the transmission is $4000, and I’m not the first with this problem a friend of mine had the same issue a couple weekend before me.Had two mechanics one of which was from the dealership tell me this was happening a lot! …”

“My car would not move or go into gear. I was told it was my transmission but the diagnostic said it’s my powertrain control module. The mechanic finally admitted he broke my transmission.

I did some Google searches and tried to figure out. Once I figured it and couldn't get it off of there myself I took it to a Ford dealership. They told me the MyKey had to have the admin key and they would have to cut one etc and then the labor all together would be 400 dollars. I was floored how did this even happen? …”

Breaks were then hard to push and vertically impossible to slow down.
