Known issues on the 2008 S80. The 2008 S80 carries 7 recalls and 26 owner complaints. The fuel and propulsion system (6) leads the complaints, ahead of the electrical system (5), seat belts (4), structure (3) and visibility (3); 4 complaints reported a crash and 2 an injury. On certain 2008 S80 cars, central control module software might fail to wake the fuel pump module, so the engine could start on residual pressure and then stall. Certain cars could lose the cooling fan to a programming error in its control module, letting coolant temperature climb. A third campaign on certain 2008 S80 cars addressed front outboard belt anchor cables that may wear with age and fail to hold an occupant in a crash; dealers replace both cables. Fuel system, cooling and electrical diagnostics appear here with wiring diagrams, procedures, specifications and torque values.
