To be fair, my car has one specific circuit board that can only be fixed by a dealership mechanic. Found out about that one after it malfunctioned on the highway, my car turned off, and I couldn't use the breaks while coasting at 65 mph.

Wish my car told me that so I wouldn't have wasted all that time.
