From AB
Manufacturer: BMW of North America, LLC
SUMMARY: 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).
CONSEQUENCE: Intermittent light operation reduces the ability to warn other motorists of the driver's intentions, increasing the risk of a crash.
