My main gripe is the roughness of the engine starting and stopping constantly. Annoying

I'm sure there are others out there but here is an Auto Start/Stop disabler

Electric water pumps are a real thing

Yes, the enginerds have thought of this, yes they have solutions, no its not some critical point of failure. Frog snacks people have you never worked with engineers? Yeah they occasionally overlook things but 99% of the time when designing a project you got dipship jimmy in the corner asking "Well what if plutos gravity suddenly increases 400fold, will the car have enough downforce to counteract that?" So if we are scraping the bottom of the pot THAT hard (at which point you've dug through the pot and halfway through the burner) they probably have thought of it and come up with some form of mitigation....... Not that I am venting about the corkstuffers I work with and their constant whataboutisms...
It in theory will actually save your engine in terms of longevity because you aren't needlessly wearing out the engine bearings having the damn thing run when you aren't moving. Would you rather rebuild an engine or toss in a new starter?

That says an hour or two and a couple hundred bucks. I'd like to see an engine rebuild go that quick...
As for me I ABSOLUTELY want stop start in my Bronco. After sitting in constant CO traffic caused by accidents/construction it is 100% worth it to me. Being stopped for 10 minutes at a time, wasting fuel and killing the turtles is not acceptable to me.
I test drove an '18 wrangler manual with auto start stop. It takes some getting used to because their system would shut off at stop signs, so you have to move slower with the clutch to not engage with a dead engine and stall out, but if you're not trying to slam shift like you're at laguna seca you'll get the hang of it.
About killing the turtles: I'm only half joking. I really do care about minimizing my environmental impact, and was pretty damn shocked at just how bad idling is. Skip to 6:15 for the punchline for all yall instant gratification fools
TL;DR
Auto start stop is like being a lightweight
Not having it is like being an alcoholic
Lightweight needs a shot for a buzz
alcoholic needs a fifth
No, the lightweight is not getting dehydrated faster for not drinking enough (starter)
But he is saving his liver (Every wear surface in the engine)

Easy fix, set your climate control temp at least 2° different than outside temp, and it won't do it. At least it works in my escape.

Thanks, noted.
If the manual has this and it cant be defeated easily, its going to be really, really hard for me to buy this vehicle. Call me crazy, but I don't want my vehicle to cut off unless I turn it off on purpose.
When I am approaching a stoplight, I go to neutral and just slow to a stop. I don't know why you would keep it in gear with foot on the clutch, that's just unnecessary wear on the clutch. When the lights turns green, I put it in gear and go.

As long as it can be disabled I'm fine. The ESS in my Jeep is just OK, and if it's used it's because I forgot to hit the button when I started the engine. If I can find the right size rock I'll take care of that.
Ooh good points. I hadn't considered battery... I did think about the oil lubrication and flowing back to the reservoir, but that didn't support my argument 
Also should probably throw in an apology if it seemed like I was targeting you, I meant that to address all the anti stop-start posters and quoted your post because it was closer to the end of the thread
https://en.wikipedia.org/wiki/Start-stop_system#Enhanced_components
Wikipedia says that the design considerations include polymers on the bearings to aid with lubrication free starts, an enhanced battery (agm or efb?), a better built starter, constant cooling system to keep things like the turbocharger cooled, and battery monitoring to make sure its not shutting off when the battery is too low to restart.
Their ford section
https://en.wikipedia.org/wiki/Start-stop_system#Ford
explicitly calls out an AGM battery being standard on the 2.7 F150, which is fantastic because I like AGM far more than flooded lead acid (less susceptible to issues with sloshing and falling apart when you're out and bouncing around).
https://owner.ford.com/support/how-...nology/how-to-use-auto-start-stop-f-150.html#
This video says it will not operate if the temp is too cool or too hot, which covers issues with the oil viscosity becoming too thick in the winter. It also says the battery and starter are both beefed up to handle the additional stress.
It does not cover the engine modifications they hopefully would have made, however.
I also cannot yet find info on the oil flow to the turbochargers, but going back to the wikipedia link (ford section)
"Late in 2010, Ford announced that its start-stop system, already used in its hybrids as well as several mainstream models in Europe..."
"and it built start-stop systems into the Ford F150 2015 model for the first time as a standard feature rather than an option.[25]"
So there has been 5 years worth of real world testing with these engines and from

Bold used below as a visual indicator for myself so I can keep organized

I see no recalls related to turbochargers for 2015, 2016, 2017, 2018, 2019, or 2020

So while I cannot come up with an answer saying it is an issue and here is how they fixed it, I can show that there has been no official action regarding that being a potential problem (but again, nothing conclusively proving it ISNT an issue. If you can find some supporting evidence that it is I'd love to geek out on it).
As for the cutting out the engine mid-flight, that is a pretty crazy notion. It sort of makes sense though, couldn't they just glide back down in the event of failures? I guess not if you're out in the Alaskan bush. If they ran the numbers though and found the incidence of failure were within some reasonable level of tolerance though I guess I couldn't complain if they cut out the engines a couple times during flight. Would add a nice level of spice...

- 2.7 turbo consuming excessive oil though
- Something wastegate valve related. I can't understand it, but I believe wastegates are for excess boost pressure, not oil
- same as 2207
- ETC_ACT and ETC_DSD PIDs should not used to diagnose possible ETB concerns because they don't display the data fast enough, or something
- 2.7L EcoBoost engine may exhibit white or grey smoke/vapor from the exhaust after cold start and/or black soot accumulation on the exhaust tailpipe
- Best summary of this one is if you replace/service the turbo, RTFM (Read the *full* manual)
https://www.carcomplaints.com/Ford/F-150/2020/tsbs/tsb-ssm-48991.shtml
- Engine Coolant Over Temperature warning caused by faulty sensor
- 2.7L EcoBoost engine may exhibit excessive white or blue smoke (solution is to replace supply line because it might be letting oil into the turbo)

What about for those who are missing or had their forscan removed ?
I’ll just buy whatever it takes to completely disable the feature. I work in the city and I’ve witnessed my fair share of these stumble and fail at intersections on various makes/models.
Definitely has the possibility of being a dangerous feature.

You can disable this with a $10 trailer plug tester. Makes the vehicle think there is a trailer attached. Works on my co-workers 2019 F150.
Something like this:

They use higher Ah AGM batteries for auto start stop vehicles to get an equivalent lifecycle. Upside is, if you use auto start stop judiciously (or disable it entirely) the battery lasts for freaking ever!
Downside is it's more expensive when you finally do have to replace it. Totally worth it for me but YMMV.
