My M3 is a 2020 which I only recently bought with about 26k miles. I started to receive notices about the 12v battery needing replacement, and whenever the car was sitting idle in my garage and not driven for a few days it would really lose a large number of miles in the range shown. Following great information read on other threads in this Forum I just showed up at the local Dealership and was elated to learn that my battery was still under warranty and they replaced it in less than 20 minutes. Over the next week the range actually went up 2 or 3 miles twice overnight, and now the loss of range is only 1 or 2 miles at the most.
