l suspect both counts of this, we likely put more cycles in 3 months then most in year and yes it sat for 12 months on lot before we bought it ($20k off msrp) dealer almost paid us to take it. On this truck I asked when we picked it up and was told 2 recalls had already been done (have not received and nothing shows any outstanding) - of our others only one did I receive the BMS recall. I'm in the same boat about it sitting on the lot for a year before purchase, and the same amazing discount from MSRP. (In fact, it was cheaper to buy that "new" truck then almost any used ones I could find!) But I too worry that my battery is probably toast. If I'd been thinking I would have insisted on a new battery as part of the deal!
