2 NHTSA recall campaigns list this model year.

    Exterior lighting:tail lights

    BMW is recalling certain model year 2008 through 2010 528i, 535i, 550i, and M5 passenger cars manufactured from March 1, 2007, through December 31, 2009. Over time, increased resistance at the taillight electrical contact points may cause damage to the ground terminal and housing of the connector resulting in an intermittent or permanent loss of functionality of one or more rear lamp functions (tail, brake, turn-signal, reverse).

    Risk: Intermittent light operation reduces the ability to warn other motorists of the driver's intentions, increasing the risk of a crash.

    Remedy: BMW will notify owners, and dealers will replace the rear lamp bulb carriers free of charge. Owners may contact BMW customer relations at 1-800-525-7417 or email BMW at [email protected].

    Engine and engine cooling

    On certain vehicles equipped with v8 engines, in conditions of below freezing temperatures combined with low humidity, it is possible for electrostatic discharge to occur at the fuel rails. If this were to occur, the engine electronic control unit (ecu) could be affected so that engine stalling could result.

    Risk: If stalling were to occur, the driver may not be able to maintain vehicle speed or accelerate and the power steering could fail increasing the risk of a crash.

    Remedy: Dealers will attach two ground cables in the engine compartment free of charge. The recall began on october 29, 2007. Owners may contact bmw at 1-800-831-1117.
