I received the update by surprise while parked at a store this morning. I returned to my truck after shopping and saw a message saying succesful update. On the drive home my dash and center screen went black and rebooted. At end of reboot, a message flashed saying "F150 settings saved". My home charging threshold settings changed from 70% to 90% but radio presets seemed to still be there.

Not EAP, but I’m heading to the dealership tomorrow for what I believe will be my third 12v battery replacement in about 5 months on my ‘24 Lariat.

The first two they said were bad batteries, and the symptoms seem like I’ll have a third.

The first signs are the radio staying on for a few extra seconds after opening the door, dash cluster not remembering my last screen setting, then the truck will stop doing scheduled departure times and won’t allow you to preheat/lock/unlock while on cell network. Seems like the truck is going into low power mode once the battery starts failing.

My system is entirely stock, so not sure what would cause the drain. Hoping an update like this would help.
