The "Auto Stop-Start" is so annoying!!!!

FORScan is a much easier and elegant solution. Turn off AS/S in the software and no annoying light constantly illuminated on the center console. A little AS/S icon shows up in the dash display at the left lower corner, very unobtrusive and only when stopped in traffic.

The other nice thing is I can always turn it back on if I want too but I can’t fathom a reason why I would want to. If only this $99 wiring harness would allow the AS/S button light to come on when you engage the system rather than constantly on due to disengagement. I’m glad there’s a solution but for $99, that seems pretty pricey for a few wires and a constant off relay.

This is one of my favorite things about the tune I just got. No light, no auto stop.

Interesting. I don’t mind the start stop. I’ve found that when I don’t want it to engage, I press the brake only enough to hold the truck. You actually have to push the brake pretty deep to get it to engage. At least on my truck.

Agree. It's pretty easy to keep the truck from turning off if you don't want it to.

Well, right wrong or indifferent, I just installed the wrap-around wiring plug to correct this A.S.S. issue. Wasn't too difficult and took about 40 minutes. I watched the video on their website, then followed the steps in the instructions, and it works as advertised. Maybe there's an easier way to address the problem, but this wiring harness worked well for me.

I forgot to turn my ASS off yesterday and had a moment of panic at the first red light I encountered... first time in forever I’ve done that....

Have my 2018 Expy and cannot get used to the Auto Start-Stop. I can't wait for a work-around!
It could be worse, at least it is defeatable on the dashboard, unlike GM where their designers figured they were smarter than the average driver regarding STOP/START!! And just wait, I read the 2020 Explorer (it will spread to the Expedition likely) will have sensors to visually read speed limit signs and keep your max speed to a few miles over those signs! Of course if that means a carjacker or other thug chasing your $80,000 SUV wants to run you off the road, guess your Ford and your family are at their mercy. It is sad to see vehicle designers feel they know more than the average driver!

2020 KR Expy.... The AS/S system, when engaged or "normal" setting, vehicle shuts off as advertised, but EXACTLY 10 seconds later, it restarts. Makes no difference whether; air conditioning on or off, aux power being used or not, brake mashed down hard, etc..... ALWAYS restarts at 10 seconds! If any of the exceptions to this system are present, it shouldn't shut off in the first place. Any ideas???

I kind of had the same question … someone (on the Forum) told me the dashboard display will inform you why it restarts. I had to navigate the appropriate screen. In my case. it had to do with charging, forgot what the actual notification terminology was.

Btw … I didn't like the shutoff/restart at first but got used to it. The engine restarts so fast I never had any delay in getting the Expy moving whenever I wanted to. It would restart faster than I could take my foot off the brake. Just my experience.

ASS hasn’t shut my vehicle off in about 8 months. The reason given by the gauge cluster is “Engine on Due To Vehicle Charging.” Additionally, when I open my doors with the engine off (when I get home) the interior lights only stay on for about 10 seconds before they shut off and I get the “we had to turn everything off to save the battery” message.

Something is clearly wrong with either my battery (it’s not holding enough charge) or my alternator (it’s not charging the battery sufficiently). And, before someone suggests it’s because the vehicle isn’t on long enough to charge sufficiently, the length of drive doesn’t matter; I did a two hour drive the other day and when I reached my destination...same thing, interior lights all shut off within 15 seconds of opening door.

It’s headed to the dealer today and I’ll report back.

Thats because the auto start stop shut it off so much previously and over worked the battery and now the battery is junk. Its not rocket science. They killed your $200 battery and saved you $3 in gasoline!

Well, maybe you're right I dunno. I found this, is it wrong?

So, finally, without wanting to be indelicate, the battery doesn’t really give a shit about multiple starts either.

(Some systems don't even use the car's battery, and rely instead on a capacitor to store sufficient charge to kick the engine over again at the lights.)

Car batteries are entirely tolerant of shallow restart cycles: start-charge-start-charge-start-charge, repeat. They love that. For years on end.

If you want to kill you car battery, deeply flatten it a few times in a row. That should make someone in the aftermarket industry very, very happy indeed.

Car batteries hate to be cycled deeply.

Or, ya know, something just broke on my vehicle. If it was a fundamental problem with the system generally, everyone on here would be complaining about their dead batteries too. And no one would have any complaints about the ASS because, like mine, it wouldn't have activated in 8 months.

I think it's more likely related to what @MrSticker posted...I have kids that leave the doors open a lot, and I leave the hatch open when I load stuff, and every time I open and close the doors while the car is sitting in my garage, the running boards deploy, lights come on, etc. In other words, I probably pull a lot of charge from that battery while it's off and deep cycle it a lot.

On the facebook group there are TONS of battery replacements being done. Many many many getting the same message you are and the batteries cost around $200 from the dealer. Its not an isolated incident. It could of course have many other contributing factors, but lets be honest shutting the engine off and living off the battery is taxing on any battery, especially with todays electronic nightmare vehicles. Hopefully the warranty covers it, but I'm not totally sure on batteries....

I get around....

I read some where its okay to get around and we shouldn't call you a ***** or slut...

@aggiegrad05 Do you have a battery load tester, or digital battery analyzer (21st century load tester)? Either of those would quickly let you know if the battery was going bad. I love my digital battery analyzer, easy to use and doesn't put strain on the battery like the old school load testers. Your battery isn't that old but if you have drained it repeatedly it could be in rough shape. Do you have an AGM battery charger? If so, throw it on for a while and see if the problem goes away.

I haven't looked into it at all on the expedition but older cars are not capable of fully charging an AGM battery so they tend to have shorter lives than they should unless you put a charger on them occasionally to get them fully charged. I would assume Ford put the proper circuits in to fully charge the AGM battery that came in it. The more time a battery spends FULLY charged the longer it will last and the more time a battery spends low...well you get it.

I would make sure to replace with an AGM battery too and not go with a standard lead acid.
