I’m glad to hear your finally getting the proper performance and driving characteristics out of this vehicle. Hopefully all this drama happened early enough that the pain of that experience will wane with time.

That’s great! Enjoy your Navi while you can. Hopefully one day you’ll be able to gain some faith in it and it becomes one of your favorite rides.

Its getting there quickly~!
I just got mine back from 1st set of cam phasers. I still have what I suspect is a waste gate rattle. For anyone who also has had this, does it cause a loss of boost? I feel like mine isn’t as peppy in it he lower rpms as before. I did just spend a week in a nautilus and I wanted to make sure I used all the gas I had to put in it before they came to take it back. I was impressed with the 2.7 turbo, it was my first time with one and I had my doubts for it in the Bronco but not anymore.

Honestly I don't think it will cause boost issues, as the pressure will keep the wastegate open most of the time. The only time the rattle should occur is when the pressure is essentially non-existent. There is basically a spring setup that is supposed to keep the gate closed when nominal pressure exists, but it's a funky actuator assembly with an actuator arm, that seems to be the real design flaw. They actually tried to replace the actuator and arm on mine before the whole turbos, didn't help. Annoying as crap, my old turbos 20yrs or more had better mechanical or electronic wastegates that worked so much better. Way to over complicate the entire assembly Ford!
Anyway, I'm going on about 6k miles on the new turbos, still no rattles.

Yes. I am about 2 weeks post-cam phaser replacement and I have noticed a lack of pep in the lower gears. I also notice a more significant kick when the turbos kick in. Previously the turbos were pretty seamless, now the truck seems to labor a bit then jump out when the boost comes on...basically more turbo lag.
I figured the "learning transmission" got reset when they did the cam phaser job and it will just take some time for it to remap itself to my driving style. Fingers crossed.
You’re describing my experience exactly!

I have a May 2019 build and I think it has the cam phaser issue. Can anyone confirm with the video? I also have the turbo waste gate rattle. https://youtube.com/shorts/bbBpOUH8RhI?feature=share

Whoa - excellent stats, Wake. I'm hoping that pans out for future posts. [my 2020 KR mfg date is October of 2019]

Fwiw, I saw mention of Toyota.
I test drove a Tundra in my frustration last week.... my god what a downgrade it would be. The Ecoboost has absolutely ruined my opinion of an NA V8 engine and the way it behaves. There were slight uphill grades that this truck would down shift at normal cruising speed and be at 4000rpms. I actually jokingly said to this salesman at one point "this thing sounds like its going to blow up". His response was it will last 300k miles. Maybe... lol. I love taking 4% grade hills at 75-80mph at 2300rpms, it behaves so tame.
I'm like so many on this forum that have dealt with this cam phaser issue, frustrated as hell but show me a better vehicle out there. A Tahoe?... no thanks. Perhaps with the update of the tundra to TTV6 the Sequoia won't be far behind?

100% yes, that’s the cam phaser issue.
We are adding a Toyota Land Cruiser to our fleet but mainly for its off road prowess. While it’s head and shoulders above a Tundra I’m under no allusions about the out dated tech when compared to our Navigator. When performing as designed the 3.5 Ecoboost is marvelous, but the Land Cruiser will be here long after I’m gone and even longer past my Navigator.

It's going to be tough to beat the reliability and capabilities off road of a LC. I came from a 4runner that I did some pretty extreme stuff in and it never missed a beat.
Isn't the new LC coming with a TTV6... but not being sold in the US if I'm not mistaken.
Yes, you are correct on the power plant. The Lexus version will continue to be sold here in the states, likely with the same power plant mated with some hybrid motors. I’m glad to have gotten the naturally aspirated V8… last of the Mohicans.
