Agree totally with Going_Going_Gone and Leadfoot17. Local auto parts store said the battery health was ok, but only at 39% charge. My little NoCo charger eventually kicked off with a "Bad Battery - Will Not Hold a Charge" indicator. A new battery solved all of the issues: IA on the passenger side, start/stop, radio shut off after 2 minutes instead of 10 minutes after engine stop. From what I've read, resetting the BMS is optional, but I did.
