K, I'll get out my magnifying glass and look more closely... If you're seeing something that says a pressure is present, then either they put in an air bladder oil source or a small electric oil pump that kicks in when the engine stops. I put just such an oil pump into the Escape Hybrid I've owned since new in 2006. It kicks in when engine oil pressure drops below 15#. Purpose is simply to keep oil pressure on the bearings. I had had a jump from engine off to high power blending in with traffic... Heard a thump. Based on my experience in Navy Submarine Force engineering, I took a hint and put that in. The Escape Hybrid is still going strong.
This is an Ngauge ODB tuning device. The picture is taken as the ICE shutdown. You can see the oil pressure at 14.79

The second pic is with ICE running but low load. (variable oil pump)

For my experiences, I can say this is from not mashing the pedal during the turn. I do believe it occurs between the 1-3 shift but that shift happens so quick anyways that it would automatically line up to the issue just due the speed of starting a turn from a stop. I have used this tuck on this route since April and this issue just started a few weeks ago and not every time; I have tried to recreate it. I don't have any gauges hooked up to monitor throttle position but, in my occurrences, throttle position was light and consistent; I would say less than 30% (school zone turning onto a main road). Coming from previous turbo cars, I feel like I am overly linear in throttle application until boost builds to avoid clipping. The left turns I am making are not tight enough to cause a traction or binding issue- I would honestly be comfortable making these turns at the speed requested in 4wd. It really feels like the computer just zones out for 2 seconds; I can at least relate to that. lol.

When ICE is running, the gauge cluster does not display the little "shelf" above zero. So when ICE shuts off and the gauge renders the bleed-down to what supposedly represents 14-15psi, the little white shelf renders.

I'm guessing the XLT display does not do the same?

ICE on:
(note that the gauge is actually fake because it doesn't increase/decrease when the ACTUAL oil pressure switches between low/high stage)

Follow up to my issue- truck was at service department today and just talked with the advisor. Per previous post, FORD asked for my information so that they could assist the tech during the service appointment; I provided it and contacted them as requested. I will pick up my truck tomorrow and the applicable paperwork but what I was advised over the phone was as follows:

Loss of power during turns, loss of power steering at start up until moving a few feet, and gear shifter stuck in park- Ford is aware of these issues impacting multiple vehicles and will be releasing a software update in July of 2022 via OTA.

Check Brake System error- brake module was incorrectly calibrated when repair for my brake failure issue occurred. It has been recalibrated and should be fixed now.

Center speaker pop- unable to duplicate

Hard downshift (intermittent)- didnt say anything and I forgot to ask.

Not exactly impressed that a fix is so far off, and not really sure if I fully believe this to be true but this is all I have to go off of and thought I would share.

Hello, Mike!
Send us a private message with your VIN and the name and location of your local Ford dealer.
I’d be happy to see what I can do to assist. Thanks!
Bump for this thread.

Anyone ever get a resolution to this? My truck has got my heart pumping a few times making a left hand turn across traffic when it has hesitated when I give it the gas. I "think" the gas engine was already running when the hesitation occurred, but I can't say definitively because I was too busy trying not to get tee boned. I wondered if it was traction control related because it felt similar to when traction control engages and you have to let off the accelerator in order to get it to reset.
This is about to drive me crazy. I bumped the car ahead of me tonight when the accelerator continued after I released the pedal. I am afraid to try and cross traffic, too many times I have been left for just a little too long in the other cars path. I have already had the TSB 21-2407 done about 2K miles ago. I finally got my boneyard truck in July 2021. These problems have been consistent for about 14K miles. I currently have 17K miles. When I had the truck at the dealer the second time for this I asked them to inquire with Ford about this complaint. They said no one else had reported these issues. Here is a thread describing exactly the symptoms I have. FORD, what is the solution???

ABSOLUTELY. I am positive it is a delay in the accelerator response. I get both situations. Pedal very slow to react to applying light pressure and Pedal very slow to release the accelerator when my foot is removed. I have had a couple situations where acceleration continued for close to 2 seconds before it released or backed down. Bumped a car a head of me already. I also have had to stand on the brake to keep from bumping cars. Try backing out of a parking space in a full lot when the reaction is slow and then the truck lunges.

I posted this same issue about the obnoxious handshake from Electric to gas, gears 1-2-3. I had the shifter get stuck in park and needed a tow to the dealer. It fixed itself but they changed the shifter anyway. Whatever they did, it fixed the handshake. I wonder if there is a transmission programing fix?

In an attempt to avoid it, what if you put the truck in sport mode and give heavy accelerator when movement is needed, would it still do it?

Nobody loves Sport Mode enough. Lol
To me it's like the Un-EV mode when called for.

Sport mode may not be the best option when dealing with slick morning conditions; at least with witnesses around. lol. On the other hand, it may be worth the traction risk though as I almost got rear ended the other day when the power cut out while turning- people are in crazy mad rush after dropping their kids off at school in the morning. I think it is a normal mode issue. Honestly, I never use eco so can't say about that one but I haven't noticed this issue while in Sport or Tow modes.

For the lag when turning left, gear shift stuck in park, lack of power steering at startup (all intermittent)- Ford Master Tech was working with Ford Specialist per the FORD post asking me to DM them and this is what the Service Advisor Manager stated:

This is known issue Ford is aware of and will be fixed with OTA software updates. Nothing the dealer can fix and that I have to wait for update: SSM 50473 Erroneous DTC U1A01:93 In The TCU (release 7/2022) and SSM 50217 DTC U0143:87 In The Trailer Module (TRM) (release 3/2022).

Reading through these, IMO, the description doesn't match my issues. The descriptors also state that these do not cause any concerns or affect vehicle performance which I argued my issues most certainly does cause observable concerns and does impact performance; not sure what is more performance impacting than losing throttle response. Unfortunately, I feel nothing more I can do since both the dealer and Ford says this is my issue and if after the updates in July, if my issues continue, it could be investigated at that point.

OfCourse it also took multiple tries to get my brakes fixed and transmission leak fixed so who knows.

I attached the documents from my service trip in case it might help anyone.

I personally think the word "Sport" has WAY too much power of suggestion.

It's actually the way the truck would come if it didn't have multiple modes. Or put another way, it's only considered "sporty" because ALL other modes are artificial gimping of the drivetrain.

So called Sport is just the 3.5 Ecoboost with all 10 gears of the 10r80. And without softening the tip-in of the throttle. :)

It feeeeels Sporty the same way a house at 65F feels warm when you come in out of the really cold. Lol

Sluggish handshake is worse in sport mode! I appreciate the post about Ford knowing about it and possibly a fix OTA update in in the works! For now, I stay in Slippery mode and stay electric full time LOL!

I agree, I think Sport could have more aggressive programming/ response but when driving with patches of snow/ ice, I feel it's just a tad too abrupt. I guess I could use the mode switch more often to switch between slippery and sport when needed (till there's a fix) but I somehow become lazy enough that seems like a pain. lol.
