2021, so I'm betting it is another battery issue

Posted often, likely 12v battery.

Maybe. I attached one of my 12v marine batteries to the 12v terminals which got it out of 'Vehicle in Battery Saver Mode', but resolving that did not allow the car to start.

I guess I should try a replacement. The car is under warranty but the dealer where I purchased it is 100 miles away.

If you own a 12v battery charger suitable for use with AGM batteries AND it can put out 10 amps (a trickle charger wont be enough) you can open the hood, pop out the panels behind and left (charge-port side) of the frunk basin and there are two battery charging posts. One has a red cap covering it (the positive post) and the black post is just bolted to the body.

I had a 12v marine battery connected to the posts which got the battery out of saver mode but the car still won't start.

Once the battery can supply enough power to the various modules, it takes a while before all the modules are powered back up. In my experience … about 20 minutes. I was able to start my car sooner, but still got some error messages about modules that weren’t responding … after about 20 minutes everything was working again. The “first start” after a dead battery may still have some codes … but wont be there after subsequent starts.

Any Ford dealer can test the battery and replace it.

If your dashboard lights up like a christmas tree when you try to start the car, and it does not start.......your 12V batt is dead.

All the lights are Ford's way of letting you know it's time to change your 12V batt.

Extended warranty? Most, if not all, 21s are past the 36 month factory warranty.

BTW, be careful not to get locked out with a low battery that won’t unlock the door.

It's a blue certified used car and came with 90 day warranty. It's kind of a mystery to me what operates on the 12v and what does not. The center console, dash, climate, lights are all ok...
I'm so used to fixing everything myself but my local NAPA doesn't carry the OEM battery so I'll let the dealer take care of it this time.

Just happened to my yesterday too! 2021, bought in Oct 2021, same thing with basically ALL of the error codes showing up and wouldn't start. Called Ford Roadside Assistance and got a free tow to the dealer. The dealer queried the 12V battery and it as at 9%. They haven't looked at the car yet, but waiting on it. Could also be HVBJB, I guess.

Invalid VIN, please try again. But I probably can’t see anything if it won’t start.

If you are jump stating it, make sure you are using the jump points under the hood not in the bumper.

Does an extended warranty include 12v.
