Not for recalls. It’s easy for folks to sit on social media and assume any mechanic can do it, but that’s not the case. The whole system would have to change. With the biggest being the requirement to track compliance with federally mandated recalls. There is no responsibility of the mechanic to report completion of a repair, nor certification regarding efficacy.

Edit: I actually just re-read your question. I thought you meant brands, but you said dealerships. So… your argument for bypassing dealerships is to use dealerships?
