I believe this is the TSB people have had and reported no change, some even had their PCM replaced and still have the issue...

This fixed it for me. They also did a trans shutter TSB as well. Not sure what the number is, but that might of been the issue as well.
What year is your car? What was done for the trans concern?

That's strange, never heard of it not working.

Mine does it so rarely that I have never bothered taking the time to go to the dealer to have it done. It doesn't hurt anything when it does it.

Same here have no plans to go in for it. Mine became less frequent as of late when the weather cooled down. But yeah there is a whole thread on this where people reported the TSB not working.

I am trying to work with my tuner to improve idle quality since I am tuned I think the TSB would be pointless to do if I flash right over it again.

Is your car randomly stalling or is it idling wierd...read this - Page 233

That's not the same issue that is addressed by the TSB.

The idle dip that the TSB is designed for will not cause the engine to stall.

Well, it seems like the thread has been hi-jacked again with other sundry issues. The back hatch opening at less than 4 mph is pretty lame, who hits the latch button at that speed? Tried this on my '15 ST (08/15 build date) today, and sure enough, at slow speed the latch will release if the button is pushed. Not something I'm going to worry about, the less monkeying Ford does with the car the better off you are.

Yup I bought a RR ST2 yesterday and they wouldn't let me take delivery of it today even though I completely own it now. Pretty pissed. Tried talking them into multiple illicit things such as "it just disappearing'' from the lot "i picked it up before the recall"

anyone know when the dealers will get this BCM software update bs?

Yes but it only does it when it's hot, and the A/C is on. It seems to do it more in stop and go traffic on a warm day too.
I notice it when I'm in car line at my sons school which happens to be right at 2pm, in south Florida, so that completely makes sense...

It is most likely your AC compressor kicking on that causes this. This is a small 4 banger and that compressor causes a serious draw when turning on and off.
