'24 F150 Powerboost - Turbo(s) Failed @ 8k Miles

[RaacerX]

Got my '24 F150 XLT Powerboost back in June 2024. Honestly, haven't been super thrilled with it overall for various reasons and I've been sort of worried about failures, although man, certainly fast as all hell.

Coming back from a couple thousand mile road trip at freeway speeds a few weeks ago, cold weather, I went to overtake someone and a few seconds later, pop; lost all power, engine light flashing, and the truck vibrated so violently I had to pull over for fear of losing control and couldn't even coast to an off ramp. ~8,000 miles. I was not towing and had maybe 500-600 pounds of gear in the bed, and I have no mods except for a mild Fox front level and some slightly larger tires.

App gave me "Major Powertrain Issues Detected", truck obviously in full limp mode, lumping at idle like a hot cam big block. Happened in an area without cell service and without an easy way to pull off the highway so I had to limp it a bit, Obvious misfires and no boost, no hybrid motor engagement, bad smell of burning rubber (like a clutch). I scan it and it's getting PCM codes, turbo underboost codes, random misfire and steady misfires on #6, etc.

Fast forward, get it towed down and dealer says a turbo wastegate failed and it over boosted, but sounds like they replaced both turbos. However I'm fairly concerned on whether a compressor wheel was damaged and whether debris entered the motor, or if the hybrid motor clutch or TC or whatever it uses lost life.

Would I be crazy to do a compression test on my own on #6? Or will I see some obvious DTC crop up if there was valve or cylinder damage on #6?

Haven't spent much time on the forums but Ford approved everything pretty fast, wondering if this is happening a lot? It also had a smathering of transmission codes too.

Did you get the CSP done where your radiator shroud is either cut or replaced with one that has a hole in front of the intake tube? This sounds a lot like the issue that program was supposed to prevent.

Sorry your truck has been giving you issues. It seems like the 2024+ trucks in general have been having the least amount of issues, especially major ones like you have had. You seem to have caught some bad luck, unfortunately.

Here is the thread on the tsb mentioned above.

Definitely wreaks of a 2024 not getting the CSP performed before it was too late.

Warranty at play now.

Friend just bought a 2024 XLT with 3.5Eco, not Powerboost. I could not find anything to suggest the issue impacts the Ecoboost but anyone seen anything to suggest it does? Seems like the base 3.5 and intake systems will be identical no?

It does…….I got mine done when the TSB came out

It depends on if your truck was equipped with the same trim piece or not.
Take a picture of hood open, right in front of the intake scoop.
Compare.

I'm betting with a June 24 purchase that his F150 did not have the new air deflector nor the old one with a trim. Mine was a September build and was one of the first ones I saw that came with the new part.

If I were you I would see about removing the spark plug for #6 and putting a snake camera down there to make sure there's not evidence of a bunch of shrapnel passing through.

If a compressor does let loose, it has to go through the intercooler before it can come back up into the intake and find a cylinder. I'd be more concerned about having everything downstream inspected including the cats. I'd also be concerned about turbo oil return lines as well. We don't know how the turbo/s looked so hard to tell what was required. I'm sure they followed proper service procedures based on what's required for the given failure. It's not like ford wants FOD induced future failure repaired on their dime.

If both turbos were replaced it's possible when it let loose the debris backed up into the other turbo killing it. The living turbo was essentially blowing debris from the dead turbo into the good turbo in a loop with the engine going NA essentially w/ the intercooler 'filtering' the large parts.

Thanks folks. I got the truck back today from the dealer but they told me not to floor it or get into too much boost for the next 1000 miles....

Looks like all the turbo return lines were replaced along with the other stuff. Haven't got any DTC yet, haven't noticed any misfires, about 75 miles put on it today. I will scan tomorrow.

I was pretty concerned at first this morning because it refused to go into electric mode, but after 30-40 miles it started to and now seems to be functioning mostly normal as it is relearning.

The transition between electric and gas is rougher than it was before, will that smooth out with miles? I'm still concerned about other damage. It also feels like I need an alignment and it was driving fine before the work; when they dropped the motor, should they have done an alignment after?

I have to head back out on the road in a couple days for another couple thousand mile road trip. I've got my fingers crossed but I'm wary and worried, I'll be in some remote areas.

So far the dealer experience has been decent. They initially did not provide me a loaner vehicle but eventually did when it was determined the turbos failed (not a truck, but a new Ford model, no complaints). They would have picked me up and dropped me off, not their fault I live far away.

TSB has of course now been performed. I did not receive the notice until last month. Initially they said it was the right turbo, so I'm going to assume it likely was caused by this.

The rough shifting was probally from the transmission tables getting reset along with not wanting to go into electric at first. This should go away with time as it relearns your driving style.

The alignment I am unsure engine work shouldnt need an alignment. But depending on what was removed for access (like the entire cab and the steering shaft) maybe something was reassembled just slightly off.

Wanted to provide an update. I've got 5k more miles on the truck since the rebuild. No CEL / codes, but have to be honest that it just doesn't feel the same. The sense of urgency isn't there and an awkward pause has developed when flooring it, that never existed before.

But she keeps on trucking along. If I can get rid of it for what I owe, I will probably move on.

Still having constant issues with the Bluecruise, and it's entirely related to sunlight. When it's sunny and sun hits the camera, the bluecruise fails. They're still fighting me saying its because of my lift, which is a factory lift.

I've got a 4k mile road trip next month, although mostly highway. Fingers crossed.
