My 3 is coming up on 2 years and 23,000 miles, and I'll be taking it on a road trip halfway across the US in a couple months.
My concern is the 12V battery dying - it seems the car is supposed to give you plenty of warning that it needs to be replaced, but that's not always the case, and I don't want to be stranded in the middle of nowhere. Would it be worth getting the 12V replaced (paying for it out of pocket of course) before I leave? Does anyone know what it costs for mobile service to replace it? It seems like it might be some piece of mind, especially if it's going to have to be replaced soon anyways as 2-3 years seems to be the typical lifespan from what I've read.
