Depending on the work involved, be prepared to bring it back. Perhaps several times.
And if anyone involved in the repair process thinks that pulling codes related to a check engine light can tell them everything they need to know in order to fix the problem... Run, do not walk, away.
The weird thing about most auto repair places is that they are like GP doctors. They start with the most common cause of an ailment and work their way down, charging you for each repair whether it is the actual cause or not. If what they do does not fix anything, will they still charge you for it?
It’s a brake problem. Stuck caliper. I figured it out myself and the instructor verified it. They’re charging $50 + parts at cost. If it was something like a transmission rebuild, I would definitely take it to a professional shop.
