Summary Verdict

The 2004 Ford Taurus, particularly with the 3.0L Vulcan V6 engine, is known for potential intake manifold gasket leaks and spark plug blowout issues. The 3.0L Duratec variant can experience timing chain wear. Transmission problems often center around the torque converter and fluid leaks. Suspension components like ball joints and tie rods are common wear items. Electrical gremlins can manifest as window regulator failures or instrument cluster issues. Interior comfort systems like the HVAC blower motor resistor and door lock actuators are also noted for occasional problems. While not plagued by catastrophic failures across the board, prospective buyers should be aware of these specific potential repair areas.
