The 2021 Ford Bronco launched with two engine options – Ford’s 2.3L EcoBoost I-4 and 2.7L EcoBoost V6. The latter powerplant has proven to be a very popular option, to the point where those ordering a Bronco with the V6 have faced longer wait times due to supply constraints. However, several Ford Authority readers who have reached out lately say that they’ve experienced some issues with their 2.7L EcoBoost V6 equipped Ford Bronco models, which had us wondering – is this a widespread issue, or one affecting a small percentage of owners?
Ford’s 2.7L EcoBoost V6 is optional on all trims, save for the Wildtrak, where it’s included as standard equipment. While the 2.3 is rated to produce 300 horsepower and 325 pound-feet of torque on premium fuel, the larger 2.7 cranks out a healthy 330 horsepower and 415 pound-feet of torque on the same higher-octane gas. Both engines utilize a 10:1 compression ratio, while the 2.3 features direct injection, and the 2.7 has both direct and port injection. The four-cylinder uses a single twin-scroll turbo to make its power, while the 2.7 has a pair of mono-scroll units.
While the 2.3 can be mated to Ford’s new seven-speed manual transmission, the 2.7 cannot and is only available with Ford’s 10-speed automatic. However, when the Ford Bronco originally launched, buyers couldn’t pair the Sasquatch Package with the seven-speed either, but Ford reversed course on that decision for the 2022 model year after receiving quite a bit of customer feedback on the topic.
Aside from the Ford Bronco, a number of other Blue Oval products are currently available with the 2.7L EcoBoost V6, including the Ford F-150, Ford Edge ST, and the Lincoln Nautilus.
Thus, we’re interested to hear if any of our other readers have experienced problems with their 2.7L EcoBoost V6-equipped Bronco. If you own one of these versions of the rugged, reborn SUV, be sure and let us know in the poll below!

Widespread issue? Really...widespread. You say that like there's thousands of 2.7 liter Broncos on the road. Maybe hundreds but not thousands. I have one huge problem though, I don't have one because I'm still waiting since Oct 2020 for mine, but hey, that imitation Bronco they call Sport, well you can get one today. Hey Ford, how's the ROI on that Bronco going? Anyone ever ask that question Mr. Journalist? Love to hear their response.
As of Dec 17th, 25,000 Broncos delivered. Definitely thousands of them on the road. I understand your frustration though. Day 1 reservation here with no build date to speak of.
yes, widespread, as in at least 50 blown 2.7 all from the range of June 21 to August 21...so 50 out of about 5000 Broncos.
How does Ford Authority verify that the yesses and nos are legitimate owners?
I own one of the first 2019 Ford Edge ST 2.7's. No problems after 3 years and 23000 miles. The 8 speed and paddle shifter issues are a different kettle of fish.
Between the problems with the 1.5L and 2.0L EcoBoosts and now maybe the 2.7L, you have to wonder. And fuel economy no better than without a turbo (had Ford gone with larger non-turbo engines). Hmmm...
I see many posts about poor gas mileage with the Ecoboost engines. My own experience with the 2.0L in the Edge AWD is 26 mpg avg all the time and over 31 mpg on the highway all the time. Once in perfect conditions I was getting 34 mpg on the highway for over 2 hours. I do think the Ecoboost powertrains provide great drivability with smoothness and quiet, low end torque and good mileage as long as you keep a light foot.
What type of issues are people experiencing?
According to Bronco G6 . Most of the 26 failures have been a dropped valve. Something got said about brittle valves. And the odd thing is the mileage. It varies from under a 1000 miles to 4500 .
Ford dealers are jacking up all prices. Dodge does not do that. I bought a Dodge now. I’m not getting jacked. Sorry. Very happy actually. Quite impressive. All my friends and family too.
Lol. Imagine not understanding that's because nobody wants a Dodge
You wouldn't know it to look around my area. And, trucks here are for work, not vanity statements.
Same here. No way I’m paying the 5000-9000 Ford dealers added market adjustments.
I just ordered a new Ram because I could order with the options I wanted without being compelled to buy a trim level I didn't want, and then $5k package over that.
As for the original topic, the 2.7 and problems, I have heard there are problems in general with the turbo engines from Ford. Had I bought the F-150, it'd have been with NA engine.
I have the 2.7 eco 10 speed in my F150. 90,000 miles and no problems. I was surprised how much power it had and I average 24 mpg in that heavier vehicle. I bet that engine in the Bronco would be fun to drive! That engine has been around for a long time now. I'm sure if there were known issues there would be some information about them.
My issue is that the '22 dealer allocation formula means I won't be getting a Bronco for years.
Having major problems with dealers stealing Bronco reservations from customers.
Edge ST with 40,000 miles. No issues at all, good gas mileage, great performance.
Specifically? We’ll, there’s a growing number of blown 2.7 engines out there from owners with less than 10k miles on their new Broncos. Word on the street is that these are from defective valves that randomly drop in a cylinder while driving.
Having said that, I’m still waiting for my 2.7 2021 Sasquatch Badlands Bronco. This whole experience feels like I’m playing a game of Russian Roulette. If only Ford would make a public statement regarding these issues then I think it would go a long way to calm some anxiety.
