Hi all
I have a 2015 for fusion that I bought as salvage vehicle with light damage in passenger door. I drove the car to the shop and it did not have any issues. After fixing the car which we changed the 2 passenger doors and got it ready. The car started having all kind of issues such as steering fault service asset required, park brake malfunctioning service required, service advancetrac. The steering buttons stopped working, turn signal stopped working. I would mention that we replaced the battery with a new one.
any idea of what's going on here

 

You could try disconnecting the battery for a while, reconnect and hope for the best. Otherwise, there could be further damage with wiring or computer associated with the accident.

Some vehicles required the vehicle computer to be notified of a battery change. You might want to look into that.
