Dead battery or deep sleep?

[Blcaldwell09]

So again, truck is dead. It was fine driving to work at 830am but at 130pm, it won't turn on. Either it didn't lock this morning when I got out or the fob did unlock it this afternoon but cannot lock it now. Zero lights or sounds. Oddly, my Ford pass was not working either--I was able to get it reset but it says the truck is turned on. Really odd. Any thoughts? Waiting on dealership to call back--they don't know what to do right now despite me asking for a tow since it's still under warranty.

My money is on a defective battery. Many Mav owners have replaced their OEM battery.

2022 Hybrid so also a good possibility it could be a defective battery cable end solder.

Next time...call Ford Roadside Assistance. It may be faster than the dealer, maybe not.
But, you will have logged into the system and registered a claim (tow) under warranty
This sort of starts the clock for customer service and dealer performance.
I can't promise a better experience but at least your claim will be supported with a paper trail. Rather than an I said/they said.

1) call roadside assistance
2) call Ford to open a case and get case #
3) tell dealer you need a loaner/rental.
4) leave it with dealer until they figure it out.

that is the steps we took when ours was DEAD. They had it 28 days. Replaced battery, as well as TCM & BCM module changes per Ford.

the more people that will do this, the sooner Ford will realize that there is an issue and just might get it resolved.

I am now on my second deep sleep issue in 1.5 years. First stranded me completely...battery replaced...this time I got a message and drove it tonight to hopefully charge it back up some. What do I need to do to get this resolved? Clearly this isn't a "bad battery" having 2 fail in 18 months.

Deep sleep isn't an automatic issue.

It is the response to your truck not being driven for over so many days (or it's voltage drops below a minimum) - since the system has no clue how long it's going to keep sitting - functions are disabled.
One of those being the modem so Fordpass can remote start/unlock the truck, or you can get tire pressure or location info from it.

So that micro-drain of remaining connected to the ATT network doesn't wipe your battery out and prevent opening and starting the truck - it deep sleeps.
And you are informed.

Of more concern is the battery saver methods - lights off sooner, or not turning on.
Now that's showing a battery not getting charged up enough and already below a certain voltage that the system feels in order to start next time, time to conserve battery now by disabling things.

If you get warnings of deep sleep shortly after a drive - ya a problem is coming.
If you get warnings of deep sleep after 4 days of not driving - be glad that system is in place.
