Summary
The 2021 Ford F-600 Super Duty, while a powerful and capable work truck, does present some potential issues for owners. The most severe problems appear to be related to the 6.7L Power Stroke diesel engine, particularly the HPFP failure, which can be a very costly repair. DEF system issues are also relatively common. Other issues, such as the transmission’s harsh shifting, leaf spring squeaks, and sensor malfunctions, are typically less severe and less expensive to address. Potential buyers should be aware of these potential issues and factor them into their purchasing decision, especially if considering a high-mileage or used F-600. Regular maintenance and proactive inspection can help mitigate some of these risks.
