Hmmm, strange you didn't get the battery low message. Maybe you had a software update of recent and they have it worded differently.....maybe something to get people down to the dealership? Thanks for the feedback HP!!
First into dealer this morning, Out in 15 minutes. Code said battery in fob low so they changed battery (no charge) and reset. We'll see if this reappears, as it was a one-of thing and hasn't repeated and there were no start/entry issues. Will watch and repost anything that happens. My service guy said yes, Chargers have this occurring, but not much activity on Journeys. I'm only 2km from the dealer so can pop over if there is recurrence If anything happens at least there is paperwork in the system.
H.P.
