I hear you, but the fact is I can't reproduce the issue on demand. Service manager is going to defend his guy who is writing what he can prove. I'm not wasting our collective time over grammar and sentence structure. I have no doubt that when they see it, they will do something. I am going...

I took my truck back in after the latest TSB failed to fix dead pedal. The service technician wrote a snarky statement that the transmission is working as designed and that I don't know how the transmission works on a hybrid truck. I did not say a word and left the $!@#ing dealership...

I am back with an update. I have had the 2nd gear issue occur with the truck warmed up. They just did TSB 25-2302. As "luck" would have it, I stopped off at a store, drove out of the parking lot with a right turn and the dead throttle occurred. This was on the way home from the service...

My truck went in for this recall and the issue remains. The Sync 4 crashes as frequently as it did before. I have an active dog who was playing with the kids and he ran for the ball as I was backing up. The image froze on the camera right at the worst possible time. Is there a diagnostic...

I'd love to know if we are all on the same version of software and chips. Do the overhauls get new control software/hardware? Only Ford knows, and they aren't focused on this.

If the issue persisted in every mode (Normal/Tow/Eco), then we'd be looking at a mechanical problem. Since the mode stops the issue, it's not a surprise that the valve body didn't solve anything.

Just to update, I can reproduce the issue at will in my 2021 PB, but only when the truck is in Normal mode. If I switch to Tow/Haul or Eco mode I cannot reproduce the issue. I haven't tried any other modes, such as Sport. 2nd Gear, cold truck, Normal Mode induces the problem.

An update- if I change mode from “normal” to “tow/haul” the acceleration issue is solved. This is 2nd gear, cold truck.

This mystery Ford account surfaced in post #5, with no subsequent response, to your point. The official Ford account seems to be more active in that other F-150 website and I have observed their intervention with positive results in the past. But, it's crickets here...

I have never had the truck fail to accelerate when it is fully warmed up. Since I determined 2nd gear, accelerating, when cold, allows 100% reproduction I am hyper focused on what is possible/not possible in traffic. I am not a transmission tech, but my thinking is a mechanical failure issue...

My 2021 F-150 XLT PB does this as well. I can replicate the issue at will as I've posted in the thread "Loss of acceleration. Mine is a2021 poweboost and it happens mostly in turns." I have talked to my dealer about it, but they've been non-committal.

This morning, same thing. Engine cold, < 3 minutes from home. I was turning left in a "Texas turnaround", the truck was in 3rd gear so I put the brakes after making the turn to get a downshift to 2nd gear. I am now heading straight in the merge lane, in 2nd. No acceleration until I get out...

My truck was cold when I had it happen yesterday.

Thank you for passing your experience with the throttle kit. I had the problem occur yesterday in a right hand turn from a dead stop. Through this thread I thought to look at the gear the transmission was in - 2nd gear. I've never had the issue happen in M2 or Sport mode. When I'm in high...

Ford doesn't collect the kind of telemetry data needed to identify the issue. We're left talking with uninformed decision makers who are easily confused. We need to capture pedal depression v RPM over time- this would identify that I have the ^@@#$@g accelerator half depressed and RPM is 1000...
