The Bronco Engine of Choice

raqball

Meh, from what I've seen, and read, from forum posts and from reputable sources, the 2.7 has just as many potential problems as the 2.3. Every vehicle on the planet has the potential for lemons, issues and whatnot..

Not sure I'd trust a video from a random YT channel with 5K subscribers.. Look at theIr other videos, all hyperbole.

2.3 -vs- 2.7 ---- 2dr vs 4dr = Meh.... Get the engine you want and get the # of doors you want..

1. The "Saw Cut" Design: While Ford moved from the open-deck "slotted" block to a "solid" block to stop coolant from leaking into cylinders 2 and 3, they still use a "saw cut" (a tiny groove) between the cylinders for cooling. Critics argue this still leaves a structural weak point where the head gasket can eventually fail under high boost or heat.
2. Heat Management: The 2.3L is a relatively small displacement engine pushed very hard. In heavy vehicles like the Explorer or Bronco, it runs high boost pressures, which puts immense stress on those middle cylinders (2 and 3).

• Compacted Graphite Iron (CGI) Block: It doesn't use the aluminum block that the 2.3L does. CGI is much stiffer and doesn't "flex" or crack under heat like aluminum.
• Two-Piece Block: It has a "deep skirt" design that makes the bottom end incredibly rigid.

The Reality Check:
If you’re planning to keep the vehicle past 100,000 miles or plan on tuning it for more power, the 2.7L is widely considered the superior engine because its "bones" are physically stronger. The 2.3L is fine for a 3-year lease, but the "band-aid" fix is exactly why long-term owners are nervous.

I'm not even remotely nervous.. These engine and door wars get old..

I've had exactly one recall on my 2023 Badlands 2.3L. It was for the rear shocks but I never got it done because I have aftermarket shocks.

Thats the only recall for my Bronco. There have been no other recalls, engine related or otherwise.

The problem with that video, is that if people take it as factual / seriously (I don't), is that it leaves them needing to sort though the noise and fear mongering to make a decision.

People should just get what they want as any vehicle, engine size, etc. can / will have issues, lemons and recalls..

• Constant Boost: In a lighter car like the Mustang, the 2.3L can cruise out of boost. In a heavy Bronco, especially with 35-inch tires (Sasquatch package), the engine stays "on the pipe" much more often just to maintain highway speeds. This creates higher sustained cylinder head temperatures and puts more stress on the turbo seals.
• Low-End Torque Struggle: While the 2.3L has impressive peak torque (310–325 lb-ft), it achieves it higher in the RPM range than a larger engine. Moving 5,000+ lbs from a dead stop requires a lot of "grunt," which often results in the 10-speed transmission hunting for gears or holding high RPMs, negatively impacting fuel economy and long-term wear.
• The 2.7L Alternative: This is why many Bronco buyers opt for the 2.7L EcoBoost V6. It offers 400+ lb-ft of torque and uses a compacted graphite iron (CGI) block—the same material used in PowerStroke diesels—which is much better suited for the high-stress demands of a heavy off-roader.

You’re totally right. Every engine and vehicle
can have component issues. But an inherent design or application can change the formula. 2dr vs 4dr is opinion. This is physics.

Weight is the natural enemy of a small-displacement, turbocharged engine. When you put a
2.3L four-cylinder in a vehicle that weighs between 4,400 and 5,300 lbs(depending on the trim and gear), you change the engine's "duty cycle" significantly.

Here is why your concern about the weight-to-displacement ratio is valid:

• Constant Boost: In a lighter car like the Mustang, the 2.3L can cruise out of boost. In a heavy Bronco, especially with 35-inch tires (Sasquatch package), the engine stays "on the pipe" much more often just to maintain highway speeds. This creates higher sustained cylinder head temperatures and puts more stress on the turbo seals.
• Low-End Torque Struggle: While the 2.3L has impressive peak torque (310–325 lb-ft), it achieves it higher in the RPM range than a larger engine. Moving 5,000+ lbs from a dead stop requires a lot of "grunt," which often results in the 10-speed transmission hunting for gears or holding high RPMs, negatively impacting fuel economy and long-term wear.
• The 2.7L Alternative: This is why many Bronco buyers opt for the 2.7L EcoBoost V6. It offers 400+ lb-ft of torque and uses a compacted graphite iron (CGI) block—the same material used in PowerStroke diesels—which is much better suited for the high-stress demands of a heavy off-roader.

If you plan on towing, adding heavy armor/winches, or running large tires, the 2.3L will be working at its absolute limit most of the time.

Second look at this video says March '26 Ford issued a "Stop sale notice under recall 26C12". Attached that recall doc which has nothing to do with 2.3L Ecoboost.

Gotta mention these errors plus several weird enunciations has me thinking this may be an AI creation..

Cheers

really liking my 2.3. had a 2.7 in my f150 which was a good engine as well. had the procal tune put in my 2025 base bronco 2.3 and its a rocket. loving my new Bronco. get compliments all the time. most say they like that it doesnt look all accessoried out with gadgets and such. i highly suggest the procal tune. fuel may cost a little more but this isnt a prius.

You watch, you decide.

… buyer beware. The newly released video is 5 days ago. But he is talking about the prior Bronco 2.3l. 2021-24

Fords 2025 2.3l MPC is a different engine with a similar advertised displacement

Picture below for video has a plastic valve cover.

• Turbo Wastegate Issues: Some 2025 owners have reported premature failure or sticking of the turbo wastegate linkage, sometimes due to missing hardware like E-clips.
• Gas Particulate Filter (GPF): The 2025 version includes a new particulate filter for emissions that may eventually require high-cost replacement or specialized maintenance to avoid clogging.
• Manufacturing Quality Control: Ford issued a customer satisfaction program for some 2.3L engines (specifically late 2023/early 2024 production) regarding oil leaks from the engine block due to faulty machining of the main oil galley.

• Carbon Buildup: Older 2.3L engines relied solely on direct injection, leading to carbon deposits on intake valves. The 2025 dual-injection system (port and direct) is designed to wash these valves and prevent this.
• "Eco-Boom" (Head Gasket Failure): Early 2.3L engines (especially in the Focus RS) were notorious for head gasket failures that allowed coolant to enter cylinders. Ford redesigned the block and gasket for later models to mitigate this risk.
• Low-Speed Pre-Ignition (LSPI): Under high load at low RPM, these engines could experience internal pressure spikes that bend connecting rods. The new 2025 twin-scroll turbo and injection strategy are intended to reduce this risk.
• Accessory Failures: High-pressure fuel pumps (HPFP), water pumps, and plastic oil pans have been cited as common leak or failure points as the engines reach 60,000+ miles.

You’re correct. Looks like a big improvement. 🤞

• Noticeable engine vibration or shaking.
• Weak acceleration or "limp mode".
• Illuminated Check Engine Light (often codes P0401 or P0404).
• Stalling or a total "no start" condition.

• Availability of Fix: As of early April 2026, the final remedy is still under development. Ford expects a permanent fix to be available in September 2026.
• Notifications: Ford began mailing initial safety risk letters to owners on March 16, 2026.
• Is it safe to drive?: Ford has not issued a "do not drive" order, but advises pull over safely if you experience sudden vibration or power loss.
