Bronco stalled out at a stop sign after diaabling the auto stop/start button. Car disabled and nothing would work. Tranny stuck in gear.

I haven't heard of this happening...would be really difficult to diagnose an issue based on the limited info you posted. Best let the Ford techs at the dealer deal with this one.

Ok, did they push the start/stop button on the dash while driving or did they shut it off on the app on their phone? Or were they driving and somehow disabled that function?(forscan)

She was driving then stopped at a stop sign and pushed the button off with her finger. Her phone had nothing to do with it. The vehicle is at the Ford dealer now. Nobody there has heard of this happening before. Go figure.

Yikes that is some crazy failsafe or something!

Thanks for clarifying. With your thread title I thought they had disabled the auto start stop function and it shut off while stopped and wouldn’t start back up. She pushed the button on the dash while stopped and the vehicle was still in gear. I would think that you couldn’t accidentally shut it off until it was in park or neutral and the Ebrake was engaged. Keep us posted on any updates.

I have to have my auto stop/start checked--it's not working!
I was at first very suspicious about this feature: it struck me as a California type of eco-nonsense to me, and I feared it would wear out the starter. But a number of posters at the other site, including one who claimed engineering insight, said these starters are a new breed and built for hundreds of thousands of starts, so I'm letting it operate in city driving.
Now it's not working! Friday I'm having a headlamp module installed, as my left parking (not headlight) lamp doesn't work (warranty job). So I'll have them look into the auto stop/start problem.

If I could just ask members when reporting this issue, could you clarify exactly what you are talking about. Because there is the push button, on/off ignition on the dash. Then there is the auto start from the app on your phone. Then there is the key fob start. And then there is the auto start/stop feature that will temporarily Turn the car off while sitting at a light and then automatically turn it back on when you go to drive. We sometimes are saying one thing and then describe something else. I want to hear about the issues, and I’m sometimes not exactly sure if the described issues are the same or different. I wish they would just give us the good old key to deal with.

For me, it's the auto stop/start function on a Badlands 4DR Lux. Three days and two trips ago I noticed it didn't turn the engine off at redlights, which is a function I first bad-mouthed but now utilize. Pressing the button on and off, no difference: whether the dash indicator indicated told me it was "on" or "off." Turning the engine off and re-starting the ignition button, no difference--the function is "off." I also experimented with different amounts of pressure on the brake pedal, turning the wheel, and paid attention to the lengths of time I wait in traffic--all factors the programming is sensitive to.

So I'll bring it up with my dealer tomorrow. Hopefully, just a settings adjustment I'm ignorant of.

Are you driving in any of the GOAT modes? I know the Sport mode will disable the A.S.S. feature, and pretty sure other modes will as well. Other factors such as ambient temp vs AC load in the cab, will cause it not to cycle off...that's all that I can think of at this point, I'm sure there are others built into the logic..but can't think of any others.

2WD-Eco. That occurred to me, so I double checked. It hadn't slipped into one of the others. External & internal temperatures have been moderate. My guess is it's something in settings.
But we're getting reports of unusual and disparate malfunctions, and the model is out almost three years now. I made my appointment because the running ("parking") light, front-left, is out. First they replaced the headlamp assembly, only to learn it's a chip module (now in stock), meaning another 22 mile round trip (my 3rd for this!) plus waiting time to my dealer.

I refer to the auto start/stop button - not the push button ignition that starts the car. There is button on the Bronco that you can push to keep your vehicle from shutting off at stop signs or stop lights ...that is what I am referring to.

I did not know there was a button. I thought it was part of the on board computer. Interesting. Is this on the Bronco or Bronco Sport? And where do they have the button? It’s nice to actually learn something new!👍🏼

Shouldn't this be in the Bronco SPORT forum? Its about a Bronco Sport?
Not trying to be a smart ass but the Bronco Sport car shares literally no parts with the Bronco truck...

Apparently the full sized bronco has the same button on the dash. I thought it was somewhere on the touch screen. At least images showed it. So it must be.

Wow...can't believe there are guys posting here that are unaware of the button that turns off the automatic on/off feature that turns off the engine at stop lights, red lights etc. It has been a feature on every Ford that I have owned for
several years.

And, as far as moving this thread, why? The auto on/off feature is on both Broncos - just located in different places.

So here is the latest from the Ford dealer. They decided it needed the battery needed replacing.

Thanks to those that showed an interest and offered their help and/or opinions.

I'm aware I turn that little bastard off every time I get in the truck!

I brought my Badlands 4DR Sas Lux into my dealer to get a headlamp module replaced--the outer ring ("dims" or "parking light") wasn't coming on. Defective module--have to wait for another one to arrive, which will make it 4 trips for this one warranty fix. I'm wondering if they failed to properly diagnose it a second time. (Grrrrrr.....)

But this thread is about stalling out at red lights, and now the auto stop/start function. Mine has ceased operation.
A dealer mechanic said there are a number of factors that affect it, including: battery strength, use of high blower on defrost, and change in fuel, as it calibrates ethanol. I had put in two tankfuls of premium as an experiment (no mileage improvement), so I just filled up with regular.

And the auto stop/start is still not engaging. Posters on other threads have said they've defeated it, but after research I decided I do want it operational. So I'll see if my dealer (Herb Chambers Ford, Braintree MA) can rectify it. But this crew has failed to address a number of other warranty glitches satisfactorily, so I'm thinking of taking my business elsewhere.
