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

I’m considering buying a 2018 Ford F-150 Diesel King Ranch from a friend. But I heard from another friend that Ford had issues with their diesel trucks and had to discontinue them. Is this true? What are some common Ford F-150 diesel problems?

Let’s explore some common issues with the 2018 Ford F-150 to put your concerns to rest! Let’s start with the good news: the reported problems are not related to the diesel engine.
Ford offered an optional 3.0-liter Power Stroke diesel engine in select trims from 2018 to 2021. The discontinuation of the Power Stroke diesel was primarily due to sales compared to the popular EcoBoost V6, not significant reliability concerns. While the older 3.0-liter diesel had some crankshaft bearing issues, this wasn’t a prevalent problem with the Power Stroke diesel from 2018 to 2021.
That said, the 2018 F-150 experienced a few common issues, including:
  • 4x4 actuator failure
  • Brake master cylinder issues
  • Engine control modular (ECM) issues
  • Doors and tailgate not latching properly
  • Various transmission issues
Overall, the 2018 Ford F-150 was a great truck, and the Power Stroke diesel engine wasn’t particularly problematic.
If you buy your friend’s truck, obtain a Carfax report and verify all recalls have been addressed. If the truck is in good condition with low or fair mileage, it should serve you well for many years.
