What are some of the common Ford F-150 diesel problems?

A buddy of mine wants to sell me his 2018 Ford F-150 Diesel King Ranch. But another friend says Ford discontinued their diesel trucks because they had a lot of problems. Is this true? What are the common Ford F-150 diesel problems?

Congrats on possibly getting a new truck! Let’s take a quick tour through known issues with the 2018 Ford F-150. And let’s preface it with some good news: they aren’t related to the diesel engine.
Ford had an optional 3.0-liter Power Stroke diesel engine available with some trims for the 2018 to 2021 model years. But according to Ford, their Power Stroke diesel was halted due to lagging diesel sales, largely because their EcoBoost V6 was too popular for the diesel to compete.
Ford’s older 3.0L diesel did have a number of issues, namely with crankshaft bearings, but this issue wasn’t reported on a noticeable scale with the Power Stroke diesel between 2018 and 2021.
Having said that, there were some issues with the 2018 F-150, though, including:
  • 4x4 actuator failure
  • Brake master cylinder issues
  • Engine control modular (ECM) issues
  • Doors and tailgate not latching properly
  • Various transmission issues
The 2018 Ford F-150 was a great truck all around. But while it did have its fair share of technical issues, the Power Stroke diesel engine wasn’t especially problematic.
If you do decide to buy your friend’s truck,
get a Carfax report
and make sure it’s had all of its recalls taken care of, too. But if it’s in good condition and has low or fair mileage, that truck should serve you well for many years.
