Recalls and investigations

3 recalls on the engine cover the 2018 model year. A recall on the same system isn't always the same failure, so read the defect text.

19V-278Apr 8, 2019
Engine

Ford Motor Company (Ford) is recalling certain 2015-2019 Ford F-150 and 2017-2019 Ford F-250 Super Duty, F-350 Super Duty, F-450 Super Duty, and F-550 Super Duty pick-up trucks equipped with an engine block heater and previously remedied under recall 18V894. During the previous repair, the block heater cable's splice connector may have been damaged.

Risk and remedy
Risk: A damaged cable could cause a resistive short, increasing the risk of overheated or melted wiring, increasing the risk of a fire.
Remedy: Ford will notify owners, and dealers will disable the engine block heater from being used. When replacement cables become available, a second notice will be mailed and dealers will replace the engine block heater cord, free of charge. The recall began May 31, 2019.

Water and contaminants may get into the block heater cable's splice connector causing corrosion and damage.

Risk and remedy
Risk: When the heater is plugged in, prolonged corrosion could cause a resistive short, increasing the risk of overheated or melted wiring which can increase the risk of a fire.
Remedy: Ford will notify owners, and dealers will disable the block heater cable, free of charge. Once parts are available, Dealers will replace the engine block heater cable, free of charge.

NHTSA investigations into the engine on the F-150

EA23-002opened Sep 29, 2023
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 Cam Phase Shifters and timing chain have failed with only 83k miles resulting in a $7,500 repair. This is unacceptable. I would completely understand if it had 250k miles but this is a baby as far as mileage. Looking at f-150 forums this appears to be a common problem and ford has actually changed the design of the cam phase shifters so they know they are defective. Request you loook into this issue please.”

“Even with the update to add more oil pressure the camshaft phasers still failed. Happened up in the mountains on vacation. Very large rattle and jerking when first starting the engine. 71,000 miles. All maintenance has been done on time. No warning signs or build up. Ticking time bomb if continued to be driven”

“The cam phasers failed at under 65K miles. Engine makes a loud noise and the transmission shifting is affected. Took the vehicle to the dealer for inspection and I declined to repair it for now.”

“Cam phasers have gone out. This is the second time this vehicle has unsafely died in the 30k miles we have owned this vehicle. Ford refuses to help cover the costs.”

Should you keep driving it?

This page can't tell you that. 0 of 225 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.
