Also recalled in CanadaThe official notice
Defect
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).
Safety 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 CustomerRelations@bmwusa.com.
