Summary Verdict
The 2008 Ford F-350 is a capable heavy-duty truck, but potential buyers should be aware of specific reliability concerns, particularly with the 6.4L Power Stroke diesel engine’s EGR cooler and turbocharger. The gasoline V8 engines can experience spark plug ejection and camshaft phaser issues. Transmission reliability is generally good, though torque converter and solenoid issues can arise in the automatic. Suspension components like leaf springs and ball joints may require attention on higher-mileage examples. Electrical issues such as alternator failure are not uncommon. While interior wear is typical for its age, HVAC blower motors can be a point of failure. Overall, with proper maintenance and awareness of these potential issues, the F-350 can remain a dependable workhorse.
