Summary Verdict

The 2006 Ford Expedition, particularly with the 5.4L V8 engine, has a few notable reliability concerns that owners should be aware of. The most significant are the potential for camshaft phaser issues and spark plug blowouts, which can be costly to repair. The 4R75E transmission can also experience torque converter or solenoid problems. Suspension components like ball joints and sway bar links are common wear items. Electrical issues, such as instrument cluster and window motor failures, are also reported. Despite these potential issues, the Expedition remains a capable and spacious SUV, but proactive maintenance and awareness of these common problems are recommended for long-term ownership.
