2021. My wife just called me and said she stopped at a light and the engine shut down (could have been the ASS working) but when she took her foot off the brake and pressed the accelerator the engine did not start back up again and there was a message in the cluster to put the gear selector in Park and re-start the vehicle. This is the first time this has happened to this vehicle. There is only 10k miles on it too. Any ideas as to what causes this trouble?

I drove it today and it did for me. Stopped at a light and the ASS engaged. When I went to take off and took my foot off the brake pedal the vehicle failed to restart and I got a message on the cluster to put into part and start veh. It started right away. I'll be making a service appt soon and will have it checked out.
No. It's definitely an issue with ass. If ass is off everything seems fine. I'm taking it in next week. It's still under the full bumper to bumper warranty.
That is just the problem. Two years and 10k miles. Vehicle sits too much for batteries this day and age.

my 2019 still has the original battery. 60,100 miles on it.
Never using AS/S saves the battery. Useless feature that is hard on batteries and Starters

I think this is an issue specific to the 2021 and later. I don’t think I have seen the same complaint for any of the 2020 or earlier model years. My 2019 seems to just stop doing the AS/S way before it gets to the point of not starting at the intersection. I’m surprised there isn’t a TSB for this. It would be very frustrating to have your vehicle shut off at an intersection.

I had a 2018 that did this, low mileage only about 6K a year and in the 3 years of owning it had 3 batteries in total, all replaced by Ford. They seem to eat batteries if not used or put on a trickle charger. I also live where the daily temp is 70°+ all year so that may also not help
Crazy that batteries don't last in these things.

I think it has something to do with using power for the anti theft, Ford Pass link system drawing power.
Not to mention using ASS draws a lot of power everytime it starts and on short around town journeys never really fully charges or keeps the battery conditioned well. JM2C

I have a 2019 Expedition XLT and have noticed if I don't drive it the battery does lose charge. I have a product called, "Theftpatrol" it monitors vehicles location and it also gives status of battery state of charge. I check this frequently which is very helpful to know I have to get out and run it on the highway to bring it's status to 12.6. At each startup the first thing beside a cold flood start is to disable the start/stop switch. This I find an annoyance but, oh well. I have purchased an AGM battery charger and keep it sidelined just in case I need to use it. I like to propose a question here? Not doing any research is their a indicator message that will give status of battery on Settings for the battery state of charge? I suppose reading the bible owners guide to find this question but I thought getting input from others would be easier. Thanks

Get an auto stop eliminator. I installed one the first week I had my 2018 and wouldn't have this car without it.

Our 2021 just did the same thing. Took it into the dealer and their solution was to charge the battery. We'll see how long that lasts... If it happens again I'm going to ask for a new battery.

That is interesting, I have seen a message on mine that says the battery charge is too low and AS/S is disabled. Vehicles not driven enough will not get a full charge on the battery which destroys the battery. If you don't drive enough it would be a good idea to put a trickle charger on it once or twice a month to keep it "full". The worst thing for flooded batteries is not being fully charged.
Any recommendations as to what brand to get? I know there are many out there.
Update..
They replaced the battery. They also fixed a super annoying sunroof rattle (I a bit impressed) and did the wiper recall.
So... Now I really want the ASS eliminator. What are my options? This is a 2021 FYI.

You can also disable ASS in Forscan if you prefer a software solution.
I didn't think Forscan worked to disable ASS on 21's.
