Summary Verdict

The 2006 Ford F-450 Super Duty, while a capable workhorse, exhibits some known reliability concerns, particularly with the 6.0L Power Stroke diesel engine. Issues such as EGR cooler failure, oil cooler failure, and head gasket problems are relatively common and can be costly to repair. The gasoline engines, while generally more reliable, can suffer from spark plug blowout. The TorqShift automatic transmission is robust but can develop issues with the torque converter or solenoid pack. Suspension components like leaf springs and ball joints may require attention due to the truck’s heavy-duty nature. Electrical gremlins, such as instrument cluster and alternator failures, are also documented. Despite these potential issues, many F-450s continue to perform well, especially those that have been meticulously maintained and had known problems addressed proactively.
