Why Some 6.7 Power Stroke Years Are Problematic

These problems can lead to expensive repairs and reduced performance. Understanding these issues can help you make an informed decision when buying a used truck.
The Year to Avoid: 2011 Ford 6.7 Power Stroke
The 2011 model year of the 6.7 Power Stroke is widely regarded as the most problematic. As the first year of production for this engine, it faced several teething issues that were later addressed in subsequent years. Here are the main reasons why the 2011 model is considered less reliable:
- Turbocharger Failures: The 2011 6.7 Power Stroke was equipped with a single-sequential turbocharger that was prone to failure. This issue often resulted in reduced power and expensive repairs.
- Fuel System Problems: The high-pressure fuel pump (HPFP) in the 2011 model was known to fail, leading to metal shavings contaminating the fuel system. This could require a complete fuel system replacement.
- Exhaust Gas Recirculation (EGR) Issues: The EGR system in the 2011 model was less reliable, leading to clogging and reduced engine efficiency.
- Radiator Leaks: Many owners reported radiator leaks in the 2011 model, which could lead to overheating and engine damage if not addressed promptly.
While these issues were not universal, they were common enough to make the 2011 6.7 Power Stroke a year to avoid for many buyers. Ford addressed many of these problems in later model years, improving the engine's reliability and performance.
