Someone at BN pulling the “it’s 28 motors out of 73% of all broncos delivered” crap again. Whatever they can do to lower the failure rate and keep the rainbows flowing!
He’s saying 2.7’s are essentially 73% of all broncos delivered so far. Probably pretty close, but again- this is not 28 out if that number. It’s 28 out of forum member owned 2.7’s.

Just be thankful you don’t have a brain like that.

Man, much appreciated
- this gives your engine build-date: 08 Oct 2021
- ? and current mileage is ~ 2000 ?
- ? do you have a better # for the mileage ?

2058 miles

My 2.7L is squarely in the danger zone, a verified failure on my exact date, and I'm right at the upper end of mileage, so it should be happening any day now. I can sit at home or drive something else, but I choose trial by combat. It either won't fail, or they'll have a fun time towing it out of the places I'm taking this thing, and the mechanics will have a fun time picking valves out of the muffler. It's kind of a win/win to me.

Is there nothing that can be done preemptively, service-wise for those of us who are in or close to the (known) "danger zone"? I've noticed an electrical flicker in the instrument cluster a few times, although I think it only happened when the ASS was on and I took my foot off the brake at a light. Reminds me of an issue I had with a loose battery connection in my Taurus but I checked the battery terminals and nothing was loose. Anyone else experience this, especially if your engine blew?

I had a similar issue tonight pulling out of driveway. The instrument cluster flickered, check engine light flashed, engine seemed to stall for a split second, then fired up and was fine the rest of the drive. Waiting...

There was an audible "click" when mine flickered. Did you notice that also?

I didn't, but I could have just missed it. Radio was already blaring. I will report back if it happens again tomorrow.

There were reports of loose fasteners common to the fuse box...could this contribute?

Better dump these heaps before the used car market bubble bursts and ‘21 Bronco 2.7s become universally infamous for their unreliability

Until we know what fails, why it fails, and the conditions in which it occurs, we'll never have an answer to that. Right now all we can really say is
a) drive it well beyond the statistical "danger zone" and hope you don't change those statistics
b) park it and don't even bother starting it until the issue is identified and TSB/recalls issued
c) sell it and get something else?

Life insurance company wanted to know today why I was significantly increasing the policy on my wife. Told them because she drives her new Bronco w/ the 2.7 through mountain passes & shelf roads (8k-10k’) on a regular basis with many not having shoulders to pull off on when her engine blows.

And from my experience w/ my ‘17 f150 and the 3.5EB, it was sh*t show every time it went to the dealership. I gave up after the 4th trip and having 17 different codes popping up along with electronics stop working. Fixed it myself with 2 sensors that they damaged when working on other issues. Funny thing is, its now been trouble-free for 1.5yrs/20k miles and not been back to the dealership during that time.
