I want to throw this question out there to all the folks having these internal engine issues....what is the oil change interval, what filters are used and oil type? Is the engine brought up to operating temperature before driven? Is the engine allowed to idle for a few minutes to cool down and let the twin turbos spool down before shutting off the engine? I think I can guess some of the answers...

i would guess to say that the majority of us on here are aware of proper turbo & engine care, & take significant steps to maintain these for longevity & performance.

as for myself: full synthetic every 5k, oem filter, & always a 2 minute cool down - that is perhaps the most crucial part, to get cooler oil cycled through the turbos prior to shut down & keeps the turbos lasting forever. my 2001 audi allroad 2.7 bi-turbo has 240k all original equipment on it - NEVER been cracked open for ANYTHING & runs like a monster still to this day. true that the cooldown is key for turbo longevity, & that vehicle is living proof. the audi dealer can’t even believe it’s lasted so long tbh.

edit to add: my phasers were just done at 42k, purrs great for now but not planning on it staying that way. there is absolutely something going on with these regarding some reason for low oil pressure at startup / poor parts mfg / design or likely a combination of all.

i wouldn’t go down the road of trying blame ANY of this BS on the owners, nor imply that we are somehow not properly maintaining these vehicles & this is a factor here. sorry, but there is only one party responsible for the mess, & that’s Ford. and only Ford. to suggest otherwise is just plain insulting to those who are dealing with this issue prior to 100k, much less 6 times @ 24k. do you work for them or something?

Mobile1 full synthetic for SUVs, no more than 6K miles - oil life gauge always shows a lot of life remaining. Motorcraft FL-500S filter. We jump in and drive, should be able to do that with a modern day car I would think. Also when we get to the store or for that matter, home, we shut it off rather than sitting for a few minutes. Hope that isn’t the cause of the problems because if it is, that is an unsatisfactory engineering flaw in the engine/vehicle - have never done that with any vehicle I have ever driven since the 1960s and have never experienced any issues before.

I read the manual. No warnings about sitting in a parking lot for several minutes before turning off the truck. If that’s a requirement they should mention it.

I don’t think it is at all, just a little bonus protection for the turbos. That said none of these problems should be happening regardless of how long do you let the truck run before and after driving.

The short idle before shut down is old school turbo 101, to allow cooling and prevent damage from heat soak. Modern turbos have much better cooling.
Having said that, if I just finished 100 miles towing a significant weight, I would still idle for a bit to allow the turbos to cool before shutting down.

I'm not trying to stir up a poop storm, you may have legit manufacturing issues. I maintain a fleet of vehicles, construction, marine and off road equipment, none of them with any internal engine issues. I am a stickler for warm ups, cool downs, 3K or 100 engine hour oil & filter changes and employees know this. Even my wife and kids know to warm up their cars and trucks at least 10 minutes before leaving home. Call me nuts but my way works for us. I have pulled heads on 200,000 mile engines for broken exhaust bolts with zero cylinder wear and the factory cross hatch still visible.

Deadman,
Have you recently hauled a GM tech that was killed by a Ford? If so that maybe your problem.

Have a 2017 EL with 60K on it and it's been perfect and when I drive it I keep it hammered !! Just makes no sense all these issues.
