Didn't look for that. Which module?

I'll have to make some time to play around with it. Plenty of addresses related to it, and with some things, it takes more than just one adjustment.

I had no idea that this system causes so much passion. I drove 75 miles yesterday for the recall to be sighed off by the dealer. I had checked it and the line was secured but of course they would not take my word for it.
Anyway, still no Stop/start operation. I guess its Tango Uniform. Good.

I have a GT that was built in 3/24. I have the start/stop system and no $1000 gas guzzler tax. I'm currently at 960 miles and it has not shut down once. I checked all the conditions for to operate and still no shutdown. I'm not complaining and don't want the dealer messing with it.
I am curious if anyone else has issues with the system not working.

Everyone HATES the AS/S system.

His is not working and he likes it not working!

Why would he want you to change that?

I noticed a difference between our two vehicles both with Start/Stop. The Mustang will stop at an intersection and then start again in a few seconds for no apparent reason. On our Toyota Cross it may do the same but the dash pops up a message telling me why it started, usually it’s because of heating or cooling is active. Meaning if the cabin needs heat or the A/C is on it starts the engine. If Ford showed the same info then we would know what’s going on which would negate these questions.

It's documented - I've read it somewhere. If you let up on the pedal just a smidge, the Mustang will restart. If you move the steering wheel at all, it will start back up. There are a few others, but I don't recall exactly what they are.

My DH doesn't have AS/S, and I turn it off whenever I drive my '21 F150.

Great imputs. Thanks.
I did have the hydraulic line recall checked yesterday. All good. I tried to send a picture but they needed to look see. Still shows as an open recall because of the cyber attack they can't enter it in the system.

As a Air pilot I like all systems operational. I can shutdown the S/S with the button.
BUT it's inoperative and as you said I'm not going to let them mess with it.
Thanks

It never bothers me to just press the damn button (to turn it off) in my F150 whenever I drive it. I never could figure out why having to do that bothers so many.

My 24 is in the shop as we speak for the same reason. It will not activate for several reason however my issue is that It’s showing low voltage. It will not activate if the battery is lower than 50%. Mine is showing that it is at 50% or lower however the battery is showing 95% they don’t know why the computer is showing that. So they have it in the shop looking at it right now. As soon as I get the info I will share what they found.

Thanks for the post. Please let us know the outcome.
No indications on the dash, right?
I'm not going to take mine in as of now.

FULLY charge the battery then do a BMS reset. That resets the SoC based on the current state of the battery/system. But of the battery is defective, it will need replacing.
