Bronco 2.7 Engine Issues

[trader979]

First and foremost I am not looking to bash the Bronco and I realize this is a gladiator forum. I was just curious if anyone has been following what’s happening with their 2.7 engine? Seems some are failing after a few thousand miles. For those concerned about their gladiators, it looks like the grass isn’t necessarily always greener.

There’s been 33. Some think it’s significant, some say it’s no big deal. That seems like a lot of engines when you’ve only sold like 15K Broncos. They’ll correct it though, they obviously know it exists since they’re replacing entire engines.

It's not like this is a brand new engine, or even a brand new generation. Pretty sure these are still 2nd gen Nanos, which are in their 4th production year. Shit happens, especially when so many parts are supplied by outside vendors these days. It may indeed be an issue, but most likely it's a small batch, and really no different than Jeep or any other modern vehicle run might experience.

Dang I thought the 2.7 was supposed to be the more reliable of the two options. They shoulda dropped that 3.0 Powerstroke in that fat pig. Karma is a bitch Ford. Give the folks what they want!

My 2021 GMC with the decades old 6.2L gas motor had bad lifters and was torn down for replacement. GM got a bad batch of parts, when mine was down the dealer had another 5 waiting on replacement parts. There was a build date range.
This happens in any industry. Its not karma, its shitty parts that made it past QC.
We are all tired of hearing about part and labor shortages, but when you cant find people to run a plant and materials are scarce, shit happens. Shit happens in the best of times too.

The bigger surprise to me is the issues with the new Toyota Tundra engine.

The jeep 3.6 has had it's issue's as well. The wife and I just built a Bronco last Friday with the 2.7 in it. If it were more than what I've read about I'd be concerned but I'm not to worried about it. I was real impressed with the power the one we test drove had with 35's on it, made driving the Jeep feel underpowered honestly, it had a lot of pep. I would not get rid of my JT for one but the wife wants one and she's content with selling her BMW X5 50i to get one.

And you hit on a common theme - "I won't buy first year...xxxxx" or "it must be good it's been around for xx years".
Both are BS - why? Because every year things get changed. Cam profiles, minor mods, tunes, whatever, all to meet CAFE and EPA rules, or to get more power and so on.
Look at the 3.6 - you'd think an engine around for a decade would have zero issues. And for the most part that's true - but how many cams have been replaced in the last couple of years in Gladiator engines? It's a decade old engine - Millions of miles........
Yeah, but things change.
The 2.7 has been around - but what's different between the earlier versions and those used in Bronco?
The 3.6 has been around - but apparently there are differences between the 3.6 used in WK2 and JT for example. Why? Because the TSB for engine misfire caused by spark plugs ONLY applies to WK2 -not JT.
They may be the same basic 3.6, but different tunes, cams, assembly plants.............
Pick any engine in the last 70 years and you'll find constant changes even if the displacement was the same and the outward appearances are the same or similar.

I generally don't buy 1st year as well, broke that on the JT because I had to have one. We thinking about building a 2021 Bronco last year but waited because honestly I wasn't sold on it and I just didn't feel comfortable buying the 1st year. We built a 2022 so I'm hoping they have worked out most of the kinks but I'll still more than likely get the extended warranty just in case.

Some kinks will be worked out, but with each new model year, new ones will be introduced. The days of the "first year" being bad and subsequent years being fine are done. Otherwise, why is anyone having any issues at all, any what-so-ever, with a 3.6? And why JT and not WK2?
Maybe things like roof issues, leaks, that sort of thing, but there will likely be new issues as things are "improved".

You spelled 5.0 Coyote wrong.

 

[bleda2002]

Nothing new here, the ecoboom moniker is well deserved for the engine line. It seems you either get a solid one, or one thats going to grenade fairly early in life. The vast majority are fine, but i personally know of quite a few in f150's that decided they were going to blow themselves to smithereens.

I don’t disagree with ya there lol

100% agree, that's what extended warranties are for.
