A little over 4000 miles when it’s started to rattle. Just over 10000 today when it died.

Do you have the warranty service paperwork that you would be willing to share listing what parts ware replaced? Knowledge is power.
I feel like we should get a shared dock going for this thread to track all these failures. If we can narrow down to specific batches maybe we can get some proper response from Ford Corp.

Wrapping this up here. It took my service shop three weeks to get it done. I took it back today so technically I haven't tested it yet. I'll know if it's fixed or not tomorrow.
The dealership didn't offer a rental. I opened a case with Ford and since my car was under warranty they rented me one.
Communication was lacking at the beginning, no info about what was wrong, where they were in the repair process, etc. But after I became a pain in the neck by calling and messaging, things got better. One thing they told me was that the survey that I filled out with low ratings made them change their ways. I always thought they never pay attention to those. I was upset and filled out the survey honestly.
The list of things that have been replaced is massive. Apparently, they had to take the engine out to get the repair done. They didn't have to but they said it was easier.
All in all, it wasn't a pleasant experience, but I am glad I got my Brocno back.
I hope @Ford fixes this issue permanently and no one else goes through this.
Are you seeing these cam phaser failures to be widespread in the 2.7 ? Maybe in the Ford service technicians forum ?
What percentage of the engines do you think are failing ? Way less than 1% ?
Are they Bronco only ?
Or F-150 also ?
Here in B6g the 2.7 owners have been reporting these almost 2-years now. So they don't seem confined to any range of build-dates. And after the major repairs are done some owners have engine failure again several months later ( e.g. @MNRiderTTU )
Are you seeing these repeated failures frequently ?
Do you think the 2.7L is somehow risky or fragile in the cam phaser design ?
Why are so many owners having these failures ?
After delivery it seems the cam phasers can run fine for months and then somehow they go out of adjustment. You wonder if the 2.7L design is somehow non-robust or fragile, unreliable

They're pretty widespread on all 6 cylinder Ecoboosts, not just 2.7 and not just Bronco. It has been an issue for years. I have no idea what the percentage is, but so far it has been decently low. The dealership I work at has only had a handful in the last 3 years.
Some seem to have the problem, others don't.
I have 20K miles on my 2.7 and it has been flawless, but we have had other ones in the shop with less than 1k miles with very bad phaser rattle.
As far as repeat repairs, I haven't seen any on a Bronco. But it's still a little early to tell if that will be an issue going forward.
Either way, it's not something I would really worry about if considering purchasing a 2.7 Bronco.
They've had problems with cam phasers since what, 2005?! You'd think they would figure something the fk out to fix this issue after 18 years.
2.3 does have phasers on both its camshafts, but it’s a different type of design.
I have a friend whose accord had the “cam phaser” replaced under warranty. No manufacturer discloses warranty data.
That's right they're both dual over-head cam (DOHC). So the 2.3L has two camshafts, and the 2.7L has four camshafts across two separate cylinder heads
In the 2.7 it must be more trouble to synchronise the two separate cylinder heads
Sorta makes sense that synchronising two camshafts in one cylinder head might not be so hard. But synchronising four camshafts across the two separate cylinder heads could be more trouble
This could explain why the cam phaser problems show-up in the 6-cylinder engines

Same here, had planned 2.7 build from July '20 reservation. Then November '21 changed order to go with 2.3 - then got scheduled couple months later
And the 2.3L is a total BEAST ! ! !
Has a lot more power than I need

The 2.7 has dual overhead cams for a total of (4) four camshafts.
4 cams for a 2.7
As far as how phasers work, there are probably some decent youtube videos that would help you understand how everything works. Typing out the description and operation would take a while to explain lol
Ok just got back from the dealership to pick up my bronco from cam phaser replacement, dropped off 7/25, parts arrived 8/18 from backorder, picked up today 8/24. Havent really had any time yet to really go over it but seemed fine on the drive home. Here is the full parts list from my service, i know a few people have been asking for this. Let me know if you guys have any questions and ill try to answer best i can

It's a common problem with the 2.7, 3.0 and 3.5 Ecoboost motors. I just had them replaced in my wifes 2017 F-150 (3.5 Ecoboost) with 75,000 miles. It cost me $3,600 for the repair, including a new battery and belts since it was already apart.
I have a 2022 Badland with the 2.7 and haven't had any issues so far 25,000 miles. I was a 1/07/2022 build.
