Battery Issues?

[spo0587]

Last week, Expy didn’t restart from auto start stop. Transmission gear selector flashed. Dead in traffic. Was able to get it to restart. Since then I’ve made sure I’ve turned auto start/stop off and no issues. This morning no start. One running board was out, one was in. Only thing I’ve noticed is Sync screen has been staying “black” lite when truck is off. Are these related, seperate?

Last week had battery tested. Tested fine after auto start stop. It’s an AGM that’s only 1 year old.

It appears the running board was stuck trying to close and that’s what caused the battery to die?

Your one-year old battery should have a replacement warranty. I would replace it.

I'm not sure replacing the battery is the best place to start. Some places won't exchange a battery that tests good. Do you have the specs from the battery test? I would check the charging system next since the battery already tested good.

My 2023 Expedition battery had to be replaced under warranty at eighteen months. It never quit on me, but I started getting warnings on my app. The dealer confirmed it was going bad. I have never had a battery go bad anywhere near that soon.

Batteries that sit and end up low on charge can be damaged and have a very short life especially in extreme temperatures cold or hot or both.

Im not really sure why you responded to my post like this. Our Expedition gets driven every day and has done several long trips. And Ive lived in the same climate for 45 years.

Your not alone. I drive my expedition everyday.

I had a Motorcraft AGM battery installed backbin February 2023 and I just had it replaced while my vehicle was at the dealer for a separate issue. They told me that my battery is bad and replaced it for free since it was under the 3 year warranty. I had no clue though that it was bad though because it seemed fine and didnt have issues beforehand.. but anyways im glad they caught it early..?

Ive said this iin a different thread as well but Something is definitely going on with Motorcraft batteries. Not sure if its just the AGM batteries but Im seeing alot of issues recently with these. Even the dealer I was atbsaid alot of them are failing but didnt have any further info on that when I asked. They even replaced it with a different brand AGM. But that could have been because they were out of MC batteries? Haha i fifnt even know they replaced it with a different brand until after Ingot home and check under my hood. Went with a Napa AGM

Simple before you owned it it sat snd likely was dead. Its the number one reason most batteries are junk on recently bought cars.

again, do a charging system test. its tricky with smart charging, as the alternator is controlled by the PCM to only charge the battery 'just enough'. On my wife's Mercedes, there's a LINbus connector on the alternator, unplug that and the alteratnor reverts to 'dumb charging', running at 14.2V or so after a cold start and tapering down to 13.6V to maintain the battery. With the LIN bus connected, the Mercedes PCM turns the alternator down to 12.6V most of the time, as long as it thinks the battery is at least 70% charged. AFAIK, the Ford does much the same thing, except the LIN bus is on a connector with another signal which I think is required, so you can't just unplug it.

I have bought 80 new vehicles. Why is this the only one that suffered your theory? You assume a lot without asking questions.
