My auto stop/start is no longer not working...

I have a new 2017 Escape SE with the 1.5l engine (build date 6/16) with a problem that it looks like many of you would be jealous of. When I bought the car, the auto stop/start worked as advertised. It was mid-summer with the outside temp at 100f+, and the AC set to 74f. So I know that the stop/start will function even with the AC on and high temperatures outside.

Now, approximately 1 month into ownership the auto stop/start does not function at all at any time even in early morning or late evening when the temperature is lower than he AC setting. The grayed out setting does show on the dash when it should come on. There are no other issues with the car or warning lights of concern on the dash.

I did install a Curt hitch mount and about a week later the lighting kit. I was nowhere near the engine or other electronics or vacuum lines (yes, I read the manual to see what the stop/start criteria are). I have gone back over the installation areas and cannot see any pitched/damaged lines or any problems (it was an easy installation).

I’m a grocery getting, kid driving kind of guy so maximum fuel economy is kind of important to me, so I would like to fix this if possible.
Any advice on how to troubleshoot this problem would be appreciated. No service actions are noted in the online/maintenance “My Ford” account, not even the window reprogramming recall.

What model did you get to fit okay? I'm considering putting a Red Top in mine as the battery is still the original.

I bought my Escape used few years ago, it even had its engine replaced under warranty and at no point did the auto start stop feature ever work on the car. The button is always greyed out, and if you turn it on, it lights up to “off”.

-instrument cluster settings have been check as well.

-car had normal running temps all the time

-brand new battery as well

-brand new engine a year later and auto start stop still doesn’t work

But the auto start stop doesn’t work. Not that I really care, but this point I’m curious if the vehicle is tuned. Earlier today, what appeared a 2006 BMW 330i with bolt ons went head to head with me from a dig and he was always half a car to a car length behind me. So now I’m curious is my car tuned? But that wouldn’t make sense since it has a new engine as well wouldn’t that have erased the tune if it did have it?

Any ideas?

It may be worth checking to see if there is anything plugged into the OBD port that may be disabling it. Also the previous owner may have disabled it through Forscan.
