What owners report

  • Headlight wiring insulation deteriorates and exposes bare wires, which owners describe as a fire hazard.
  • Sunroof drains overflow or clog, letting water reach the battery and control modules in the wheel well and causing them to arc, spark, and melt.
  • A loud popping noise and flames were reported coming from underneath the vehicle while shifting into reverse to parallel park, with no warning lights on beforehand.
  • ABS and dynamic stability control warning lights illuminated after the car felt momentarily unstable while cornering.
  • Airbags failed to deploy in a multi-impact rear-then-front collision.

2008 BMW M5 recalls

2 NHTSA recall campaigns list this model year.

  1. NHTSA 13V407000Sep 11, 2013Electrical System134,100 vehicles

    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].

  2. NHTSA 12V126000Mar 26, 2012Electrical System367,682 vehicles

    Electrical system:12v/24v/48v battery:cables

    Bmw is recalling certain model year 2004-2010 5-series, model year 2004-2010 6-series, model year 2006-2010 m5, and model year 2007-2010 m6 vehicles. The insulated bulkhead connector for the positive battery cable may have been incorrectly attached to the trunk floor panel, which can lead to a loosening of the bolt connection. As it loosens, an increase in electrical resistance at this cable connection is possible and could cause the cable connection to overheat.

    Risk: Overheating could lead to a fire, even while the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been made.

    Remedy: Bmw will notify owners, and dealers will inspect and secure the battery bolt cable connection as necessary, free of charge. The safety recall began on april 30, 2012. Owners may contact bmw customer relations and services at 1-800-525-7417.
