Which Bronco engines are failing?
There isn’t a single Bronco engine that’s broadly failing across the lineup; reports of engine trouble have been isolated to specific engines and model years, with Ford addressing issues through recalls and service campaigns where warranted.
Ford’s Bronco lineup centers on multiple powertrains, most notably the 2.3L EcoBoost four-cylinder and the 2.7L EcoBoost V6, with the Bronco Raptor pairing a larger 3.0L EcoBoost V6. In some early model years, a handful of owners reported engine-related problems such as misfires, stalling, or oil-related concerns. Ford has responded with software updates, component replacements, and recall campaigns to fix verified issues. This article outlines which engines are in play, the nature of reported problems, Ford’s actions, and how buyers can evaluate risk when considering a Bronco.
Bronco engine lineup
The Bronco’s core powertrains are two turbocharged engines, plus a high-performance option for the Raptor. This list summarizes the engines that have been offered in the model line.
- 2.3L EcoBoost four-cylinder (turbocharged)
- 2.7L EcoBoost V6 (turbocharged)
- 3.0L EcoBoost V6 (used in the Bronco Raptor)
The two standard engines cover a range of efficiency and torque for everyday driving and moderate off-roading, while the Raptor’s 3.0L EcoBoost is tuned for higher performance and more extreme trail use.
Reported engine failures and reliability concerns
There have been isolated reports of engine-related problems in certain model years and variants, but there is no evidence of a broad, systemic defect across the entire Bronco lineup. Ford has addressed verified cases through recalls and service campaigns.
- 2.3L EcoBoost: some owners have reported misfires, rough running, or intermittent warning lights that prompted dealer diagnosis and service actions.
- 2.7L EcoBoost: a small number of cases involved stalling or loss of power under load, with corresponding diagnostic codes addressed by dealerships.
- 3.0L EcoBoost (Bronco Raptor): reports are comparatively rare; the engine has largely been associated with the Raptor’s high-performance use and is not widely cited for widespread failures.
Ford’s response to these reports has generally involved software updates, component inspections, and, when necessary, part replacements under warranty or service campaigns. Owners should verify any open recalls or campaigns for their specific vehicle and year.
What to watch for if you own or buy a Bronco
If you’re a current owner or planning to buy a Bronco, these checks can help identify and address engine-related issues early.
- Check recall and service campaign status for your vehicle’s year and VIN; complete any required updates before or after purchase.
- Monitor for abnormal engine noises, rough idle, misfires, or unusual fuel economy changes, and have them evaluated promptly.
- Review maintenance history and ensure timely oil changes and engine-related inspections are documented; verify warranty coverage for powertrain components.
Staying current with recalls and routine maintenance reduces the likelihood of undetected engine issues and helps preserve resale value.
How Ford has responded
Ford has issued recalls and service campaigns for Bronco engines where defects were identified. In many cases, remedies have included software updates, inspections, and the replacement of faulty components under warranty.
For prospective buyers, it’s important to verify that any open recalls have been addressed and to review the vehicle’s service history. Dealers often perform a full recall check as part of the warranty verification process for both new and used Broncos.
Summary
As of 2025, there is no widespread engine-failure problem across the Bronco lineup. Isolated reliability concerns have been reported for certain engines and model years, and Ford has acted with recalls and service campaigns to fix verified issues. Buyers should verify recall status, review maintenance records, and seek a thorough pre-purchase inspection for used vehicles. Overall, the Bronco remains a capable, well-regarded off-road SUV when its engines are properly maintained.
