The Most Common Ford 2.7 EcoBoost Engine Problems

Ford responded to the setbacks faced by the original Ford 2.7 EcoBoost by releasing an overhauled version in 2018. Although vehicles produced after 2018 house a more reliable iteration of this EcoBoost engine, it’s not without its flaws. Here’s a breakdown of lingering problems experienced with the 2.7 L EcoBoost:

Common Issues with the Ford 2.7 EcoBoost

1. Leaking Oil Pans

Older models faced significant oil pan leakage, notably in certain F-150s from 2015 to 2017, requiring costly oil pan replacements.

2. Coolant Leaks and ECT Sensor Malfunctions

Some 2.7 EcoBoost-equipped F-150s from 2015-2020 suffer from coolant leaks into cylinders and faulty Engine Coolant Temperature (ECT) sensors, prompting potential engine overheating and check engine light alerts.

3. Carbon Build-Up in Intake Valves

Pre-2018 models experienced carbon build-up on intake valves due to Ford’s absence of a DIY cleaning method, affecting engine performance.

4. Cylinder Head and Gasket Defects

2016-2017 F-150s faced cylinder head valve guide defects, leading to issues like smoke from exhaust, rough idle, and check engine light activation.

5. Unexplained Check Engine Light Activation

Newer models, like the 2019-2020 F-150, display the check engine light without an underlying issue, irritating but not impacting long-term durability.

6. Smokey Cold Startups

During cold weather, some engines emit blue or white smoke due to oil entering the left-hand turbocharger turbine housing.

7. PCM Calibration Issues

Certain 2019 F-150s encountered Powertrain Control Module (PCM) software problems, resulting in diagnostic trouble codes and check engine light alerts.

The Reliability Factor

Despite these issues, the 2018 and newer versions are generally reliable. Changes like direct and port injection, updated EGR systems, new turbochargers, and lightweight camshafts in the second-generation 2.7L EcoBoost engines significantly improved their performance and reliability.

Longevity and Comparison

Expect the 2.7 EcoBoost to last around 125,000 to 155,000 miles with proper maintenance, slightly shorter than the 3.5 EcoBoost, which reaches approximately 250,000 miles.

Comparison: 2.7L vs. 3.5L EcoBoost

  • Fuel Economy: The 2.7L offers better fuel efficiency, averaging between 20-26 MPG compared to the 3.5L’s 18-25 MPG.
  • Power and Torque: The 3.5L provides more power and torque, making it better suited for towing and high torque demands. The 2.7L, with 325 horsepower and 375-400 pound-feet of torque, caters well to daily driving with good fuel economy.

Towing Capacity

For 2.7 EcoBoost maximum towing capacity and maximum payload, we have made a list according to the year. Please check below:

Years / EngineMax Towing CapacityMax Payload
2021 2.7 EcoBoost9,000 lbs.
2,470 lbs.
2020 2.7 EcoBoost9,000 lbs.
2,470 lbs.
2019 2.7 EcoBoost9,000 lbs.
2,470 lbs.
2018 2.7 EcoBoost9,000 lbs.2,470 lbs.
2017 2.7 EcoBoost8,500 lbs.2,210 lbs.
2016 2.7 EcoBoost8,500 lbs.2,210 lbs.
2015 2.7 EcoBoost8,500 lbs.2,250 lbs.

Final Verdict

For daily use and better fuel efficiency, the 2.7L EcoBoost is a practical choice. However, if towing power and maximum torque are priorities, the 3.5L might be more suitable. Despite issues, newer iterations of the 2.7L EcoBoost stand as a reliable option for many drivers.

  1. Where in Fords recommendations a syn oil is required? I am a service tech doing fleet service and we are seeing 100,000 mile 2.7s and 200,000 3.5s serviced with Motorcraft “semi” syn oil
