BMW issued a recall on the 5 SERIES model

Certain vehicles may experience the loss of one or more rear lamp functions (tail, brake, turn and reverse). Failure of any rear lamp function may result in the following road users being unaware of the driver's intentions, as well as reducing vehicle conspicuity during hours of darkness, which could increase the risk of a crash causing property damage and/or personal injury. Correction: Dealers will replace rear bulb carriers with an updated design.
