Is one of the signs for cam phaser failure......

Acceleration stalling? I have the accelerator push for normal increase in speed and all of a sudden the engine will stall or have a bogged down feeling. A noticeable bogging down.

An engine "stall" means that it shuts off and needs to be restarted by pushing the Start/Stop button or turning the key.

A "bogged down" feeling would equate to a hesitation.

Is this something that has never occurred before? From my experience on my 2019 Raptor, the "Normal" drive mode mode is tuned more like "Eco" mode on a standard F-150. I find that under most conditions, even if I fully accelerate (100% throttle) to pass someone, there is almost a 2 second delay before the downshift occurs and the throttle opens. Sport Mode cures all of that; it's aggressive and near instantaneous.

Thank you

that sounds like how Lucille behaved before the TCM(?) update. She’s a 2017 though. I still get some slow downshifting but now it’s rare.

I've heard of similar issues with the 10spd transmission.

Thanks Guys.

Not sure, but I just had my cam phasers and sprockets replaced last week. Also, my tailgate wouldn’t open so they fixed that too. Truck was in the shop for a while. When I would start the truck cold, a really loud rattle and clatter would occur. Luckily I got it in before 36K. 35,930.

I believe the warranty for engine/drivetrain is to 60k isn’t it?

Yes. The Ford Factory Powertrain Warranty is 5 Years or 60K miles...whichever comes first.
