Ya, I might call down there and ask them about it. I'm still not ruling out the battery, it is going on 25 months since the build date, so who knows. I'm getting another battery test done this afternoon. Like you noted, 98% health report on a brand new battery is possible, but I'm still sceptical about a 2+ year old battery even testing close to 98%, with full CCA power still. Is it possible??? Maybe, but it's highly unlikely. We shall see...Hmmm. Yeah, sounds like an rare and obscure glitch indeed. Maybe... a next UConnect update will cure this. Or a BCM update. Come to think of it, why not just ask your service person if they've ever heard of this, they can search their database perhaps.
Otherwise I would sit on it just like you're planning to do.
