2021 raptor with a 3 month old Ford replacement battery (dealer said the original failed their test). I drive my truck at least 30 minutes a day, daily. Many times more than that. Yesterday I drove at least 1-1.5 hours total (over a few trips) and ASS never engaged. Dash says “charging” and battery voltage indicator always displays 14.5-15.5v while driving. At the end of the drive in ignition but not running mode the dash displays 12.5v and I believe the draw is 0.3 in that mode so it should be even higher resting… Weather has been in the 20s recently. Is this a normal thing for the ASS not to work? I could care less about the ASS feature but i am confident that if it is not working as intended the battery itself is having some issues. The truck did just install an update that said it would be unavailable to drive for 12 minutes but would that drain so much battery? I tried searching but not much feedback on daily driven trucks in the winter and ASS not working.
The other day I drove over an hour and battery was at 12.69V after sitting in the garage for an hour but SOC was 62%
