'12 ML63 gave me an auxiliary battery malfunction. Some convenience functions quit on me and I know that's standard. Should I go ahead and throw a new one in or send it off to the dealership? I show no record of the car ever having either battery replaced so far, odometer is right around 87k miles.

Going suggest that's just how long they last, my 12 ml63 just did the same at 110k miles. 3 weeks ago. I'm just going to get it replaced.
