Known issues on the 2008 F-550 Super Duty. The 6.4L diesel draws two of the four recalls on this year's federal record. Its battery positive cable can contact a splash shield bolt, chafe and short, and excess exhaust hydrocarbons can overheat the diesel particulate filter, causing power loss, white smoke or even flame at the tailpipe; a third campaign covers driver seats with improper welds at the side pivot bracket. Owners have logged 26 complaints with NHTSA, eight on engine and engine cooling and four each on the power train and engine. The manual's diesel diagnostics, exhaust procedures, battery wiring diagrams and seat torque values cover those items.
