I have never seen the 6v thing before. I have seen drop to 10/11 volt but never 6 on agm.
I have seen plates short out in regular wet lead acid battery do 6v. Maybe An agm could short out lead somehow. But two at the same time?
When agm battery is really low, i know adding in a lead acid along with the battery charger with it will help bring the charge up easier. Basically act like the truck uses 3 batteries instead of 2. Then hook up the charger and let it go.
But by all means if they wanna swap them for new ones- do it.
Definitely do a parasitic draw test. Most are found with a dead battery out of the blue.
The wife’s fj had the battery bite it this last week. 5 year old wet battery. Dead on Tuesday, charged and Thursday was dead again. Ordered in the Odyssey for it, installed Saturday.
