Some how, we've changed the direction of the conversation to something you lost vs a software update to the brains of the car. I'm guessing just to make the obvious point the dealership is not the cheapest place for repair.??? This isn't change the tire or get an oil change. This is something a consumer has deliberately done to prevent the manufacture from making an OTA software update. These are the kinds of changes that I want someone available right then and there to be responsible if the update borked the car.
