A ‘P07A3’ code on a 2017 Ford Focus indicates that the transmission’s ‘Friction Element A’ is stuck on, meaning a clutch within the transmission is not releasing properly, likely causing issues with shifting and potentially putting the car into limp mode; this is a serious issue that requires professional repair as it usually points towards internal transmission problems. I see slot of people are having the same issue online but yet there is no recall on this issue and there should be.
