Engine · model years 2021 to 2022

Loss of motive power. Closed oct 31, 2024, led to recall 24V-635.

NHTSA summary
On July 22, 2022, the Office of Defects Investigation (ODI) granted a Defect Petition (DP22001) and opened a Preliminary Evaluation (PE22007) to investigate allegations of loss of motive power in model year (MY) 2021 Ford Bronco vehicles equipped with 2.7L EcoBoost engines. Complainants were reporting sudden engine failure while driving resulting in a loss of motive power, often without the ability to restart. During PE22007, the cause of engine failure and loss of motive power in the subject vehicles was determined to be intake valve fracture, and the full scope of vehicles affected by the subject defect was identified as all MY 2021-2022 Ford and Lincoln models equipped with either the 2.7L or 3.0L EcoBoost engines, referred to as the “Nano” engine family. If an intake valve fractures in the subject engines, it may drop into the cylinder and contact the piston, often resulting in catastrophic engine damage. On September 29, 2023, PE22007 was upgraded to an Engineering Analysis (EA23002) to further investigate the subject defect across the full scope of affected vehicles. During EA23002, ODI visited Ford facilities to review technical information related to intake valve fracture in “Nano” engines, coordinated with NHTSA’s Vehicle Research and Testing Center (VRTC), and analyzed updated field data relating the subject defect. Forensic analysis of fractured intake valves demonstrated that the defective components exhibited “grinding burn” or out of specificatio

Reduced power during hard acceleration. Closed apr 7, 2014.

NHTSA summary
On May 22, 2013, the Office of Defects Investigation (ODI) opened PE13-018 to investigate 95 complaints alleging incidents of reduced engine power during hard accelerations in model year (MY) 2011 through 2013 Ford F-150 trucks.ODI was aware of three technical service bulletins (TSBs) issued by Ford for a condition that was related to moisture accumulation in the Charge Air Cooler (CAC) for the turbochargers.A Preliminary Evaluation was opened to gather information to assess whether the subject vehicles contain a safety related defect.The subject vehicles are powered by Ford?s 3.5L EcoBoost engine which uses twin turbochargers to obtain a balance of fuel economy and engine power based on the driver?s demand.When the driver requests more power from the engine, as in accelerating to pass, merge, ascend hills or haul a load the two turbochargers will spin up compressing the air which is then used to increase the power created by the combustion in the engine.The compressed air, which gains heat by the compression process, is passed through a Charge Air Cooler (CAC) which is designed to lower the temperature of the air in order to make the combustion process even more efficient (Figures 1 and 2).In response to ODI?s Information Request letter, Ford indicated that a misfire condition could occur after steady-speed operation under significantly humid and rainy conditions.Ford?s analysis found that under those conditions, condensation could form and accumulate on the inside of the CA

What owners wrote

“The engine started running loud and making a knocking noise. Took it to the dealership and they said it needs a new engine. Regular maintenance performed by Ford. There were no warning lights that came on prior to the engine failure. They say the engine is on back order.”

“Cam Phasers need to be replaced due to knocking sound. The problem was reproduced by an independent service center. Check engine light is displayed. This issue is under recall for ford f 150 3.5 however we own a 5.0. The same issue is occurring in our vehicle.”

Filed Feb 11, 2025

“Since new it has used 3qts of oil every 5000 miles. It has been to two different Ford shops and they say there is nothing wrong with it and refuse to do anything with it. A new engine should not be using oil. I've been a mechanic for over 50 years. No engine that I ever built used oil. This is unacceptable”

Should you keep driving it?

This page can't tell you that. 0 of 28 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
