Right, just wanted to see your technical data (like a report or technical study) to back up your claims for the Bronco Sport.
Mark did a fine job with that. :thumbsup:

I think many assume that means the computer(s) will not properly detect when the battery is low only. This would be an easy assumption because it was low battery issues that created the unsafe conditions, i.e., no restart after ASS shutdown and possible stalling at low rpm, that prompted the recall. However, there's nothing to say that the same issue, of not being able to properly detect the battery status, couldn't result in the computer thinking the battery is low when in fact it is not.
I like your logic, but I think there is one flaw: Overcharging a battery results in fairly obvious damage, and sometimes smoke and fire. I'm not aware of widespread reports of battery overcharge incidents with these cars.

Not yet, but the rumor mill will now start up...... :crackup:

I can think of a few members here that will start that sooner or later...

I have no hard data but my mechanic with over 20 years in the business said he's replaced many starters with the auto start/stop feature. Thus I bought the Eliminator first thing after buying my Badlands and haven't looked back. Even if it didn't make a difference with the engine, it was too annoying for my tastes.

I'll submit then that you don't have enough data to say the system is no longer working. Look over the list of parameters I posted previously; my guess is one or more of them were not present this morning when you system wasn't operating. Do you see a capital A in a circle with a line through it at the bottom of your instrument cluster?
Yes. When vehicle stopped with engine running and foot on the brake there is the A in a circle with a / through it.

The means the system is working, but the computer has determined one of the listed parameters is not met.

@Jude … you can see a message that might tell you the reason why the engine remains running for the case you described .. by following these instructions.

When it is safe to do so:

1. Press Menu button on steering wheel controls, right side.
2. Under Select Screens, make sure Auto StartStop is checked.
(There’s a max limit to number of selected choices so you might need to deselect something else if necessary).
3. Using the up or down arrows on the steering wheel controls, right side, get the Auto StartStop display shown in the center of the instrument cluster.

Mine is currently showing “Engine on due to vehicle charging” or will typically show the Vehicle on due to outside temperature quite a bit of time.

You can look to see what message your vehicle displays when you notice the engine remains running when you have Auto StartStop enabled per the case you described.

What specific other components are you concerned about and why?
All the other ones.

I find it ridiculous that anyone would take the position that this quick start/stop wouldn’t cause extra wear & tear versus just idling. Now, you may say that the extra wear and tear is worth it or for fuel savings or that they have done a good job minimizing that extra wear and tear. To pretend that it isn’t happening or expect me to provide you with a peer reviewed study is just silly.

Using your logic, I can find it ridiculous that anyone would take the position that the starter is going to fail quicker because of the start/stop. As mentioned, the starter used with the engines equipped with the start/stop feature are designed and built with more robust components to handle it. For me, I simply press the dash button after starting the BS to disable the feature.

I have no proof of the following statement... it would not surprise me that the issue of starters failing early due to a start/stop feature are spread by those venders that sell a device to disable it; more sales if they can convince you.

Remember the myths years ago of synthetic oils, and how they would cause engine wear?

I've had the start/stop feature on several other vehicles/makes, all kept for 4 or more years before trade in, and none had a starter fail on me for any reason, including the stop/start operation.

I'll wait to see if/when a documented BS starter fails due to the start/stop feature causing premature wear on it before I accept the myth that a starter is going to fail early.

So, if I understand you correctly you are saying you believe all other engine components experience greater wear due to the start/stop system. Is this correct? Logic would suggest when the engine is off there is no wear occurring to any of its parts.

I'm not asking for a peer-reviewed study, just an explanation of which specific engine parts you believe experiences greater wear due to the auto start/stop system.

I feel stop/start is unnecessary and stupid but I do like that there is a button to turn it off which I do when I start my BS. The move is automatic now. So no big deal.

Thank you for this info. I will try it next time I use the Bronco. Several people suggest low battery being the problem. The Bronco sat after use for about 2days without the tender plugged in and the voltage reading was 12.45 so I don't think that is the problem.
