I do mostly short trip driving. Does my battery really need replacing? Like I said, the starting is totally fine so far.
Change the battery! I just changed on my car after having the exact same scenario happen to me. The car starts as normal every time but indicates that battery is low every ones in a while and stops some functions such as radio (engine off) and welcome lights. After I changed battery this has not happened.
