Summary Verdict

The 2008 Ford F-350 Super Duty is a capable workhorse, but potential buyers and current owners should be aware of specific reliability concerns. The 6.4L Power Stroke diesel engine, while powerful, is prone to EGR cooler and turbocharger issues. Gasoline V8s (5.4L and 6.8L) can experience spark plug blowouts and camshaft phaser problems. Automatic transmissions, particularly the 5R110W, may develop torque converter or solenoid issues. Suspension components like leaf springs and ball joints can wear out under heavy use. Electrical gremlins, such as instrument cluster malfunctions and alternator failures, are also reported. Exterior rust and interior wear are common for trucks of this age and intended use. Despite these potential issues, many F-350s remain reliable with proper maintenance and timely repairs, especially those with the manual transmission.
