As Ford Authority reported back in January, a number of Ford Bronco owners have had major issues with their twin-turbocharged 2.7L V6 EcoBoost powerplants, to the point where three owners recently filed petitions seeking an investigation from the National Highway Traffic Safety Administration (NHTSA) into these problems, while 12 others have filed complaints related to that matter as well. Now, sources familiar with the matter have explained to Ford Authority that there are two main sources for these issues, which have led to total engine failure in certain cases.


As some are already aware, part of the problem with these 2.7L powerplants is that they utilize cheaper, sub-optimal valves that were acquired from a new supplier that apparently didn’t properly validate those particular components. But in addition to the faulty valves, the Bronco’s version of the 2.7L V6 EcoBoost also utilizes a less than optimal oil pan design as well, which allows the oil pickup tube to become uncovered and suck in air, which in turn can destroy not only valves, but bearings as well, particularly during spirited or erratic driving when oil is sloshing around inside the powerplant.

These issues aren’t exactly new to The Blue Oval, which experienced similar problems with the twin-turbo Ford 3.0L V6 EcoBoost engine used in the Ford Explorer ST, which is essentially a bored and stroked version of the 2.7. Now, those problems are once again surfacing in certain examples of the sixth-generation Bronco, too.

With a grand total of 32 Bronco owners filing complaints related to engine failure thus far, Ford noted in its NHTSA filing that 25,538 SUVs could ultimately be affected by this issue. So far, affected customers claim that their vehicles experienced a loss of power while driving at highway speeds, after which the Broncos would not restart due to catastrophic engine failure.

The issue regarding the valve is more or less what I expected. We know all of the auto manufacturers were scrambling to fix their supply chains so it was only a matter of time before they encountered a new supplier that didn’t have their act together.

The oil pan is surprising though. Having looked at it myself, it seems a lot more well thought-out compared to the F-150 variant. And I had assumed a fair amount of design work went into it to support the higher pitch/roll angles an off-roading vehicle would go though. Interesting in learning more about it, hopefully more info gets released as the investigation continues.

Agreed @RagnarKon - the oil starvation issue is new news to me as well. Perhaps the next version will have a dry sump setup (LOL)

I’ve had multiple vehicles with the 2.7 Ecoboost since 2016. We’ve had zero engine problems and no warranty repairs of any kind on them. We currently have two 2.7 Ecoboosts in our driveway. My 2019 F150 Super Crew 4X4 and my wife’s 2020 Edge ST.

Ford's spin is that it's covid caused supply chain issues. Although as RagnorKon points out, the redesign oil pan is concerning if it's the cause of oil starvation. Your Edge ST came with a 2.7? I thought the biggest engine they came with, was the 2.3

I agree with you. We've seen engine failures for a lifetime. I remember when the aluminum block first came out - what a disaster that was. But the oil pan design and subsequent failure really surprised me. This was an education point discussed at the Bronco Off-Roadeo that was to help the engine not fail at the steep angles for off roading. Glad they figured that out. And I would love to read what the fix is.

If the oil pan allows the pickup to pull air, the crankshaft bearings will be destroyed long before the valves are affected.

Same 2.7 in the Bronco as the F150. People are claiming they used a different supplier for valves on the 2.7’s that failed but they would be the same specs. That’s a quality control issue.

The 2.7 in the Edge ST is slightly different. It produces 10 more HP, but it’s fundamentally the same engine.

My point is the 2.7 has proven to be a reliable engine over the past several years. This is a fluke and no call for concern.

Let's get @Ford Motor Company on the phone because I have a fix for this issue!

Dump the P.O.S. little turbo engines, drop in either the 5.0 Coyote or even the 6.8 Baby Godzilla engine into those 25k affected vehicles (which my guess is I'm in that range for a bad engine as I was within the range posted on B6G last year per when it was build. Though knock on wood, no problems yet). And everyone is happy :love: My guess is a nice big V8 can't do much worse than the 17.2 MPG I'm currently getting :sick:

Or Option #2, Ford can give out LIFETIME Power Train warranties to the 25,537 affected vehicles, and JUST GIVE ME A V8! :)

I wouldn’t grant the accuracy regarding the claimed issue with the oil pan without another source verifying it. This author seems to have an axe to grind about the 2.7 and may be conflating old issues or just making unwarranted assumptions. The issue with the valves was reported last year and from multiple sources. It’s just coming back because of the reports of the Fed’s investigation.
