Okay, the other day when I had the oil changed on my X5, my service advisor asked me a few days later if I could come back to get the battery swapped out too. I was confused by that but it was apparently part of a technical bulletin from BMW. No problem I thought, I got that battery swapped out from a 90 amp battery to a 105 amp battery. I thought it was maybe because of an increased electric draw.
And then today I saw this article in Road & Track:

Ouch...this is going to be expensive once the maintenance and vehicle warranty runs out. I guess maybe I should extend both.
