2009 BMW X5 xDrive Recalls
The fuel filter on vehicles with a diesel engine is equipped with an electric heater to warm the diesel fuel in cold climate conditions. This heater could experience and electrical overload and fail to turn off as designed. Having the fuel heater stay on while the ignition is off could result in a dead battery. The heater could also overheat and potentially cause and electrical fire. Dealers will replace the diesel fuel filter heater on affected vehicles to complete this recall.
All modern vehicles use some type of power assist for the braking system. The 8 cylinder models being recalled use a vacuum pump, connected to the power booster by a vacuum hose, to provide the necessary assist. The vacuum pump may leak a small amount of lubricating oil into the vacuum hose and this contamination could result in a loss of power assist, leading to increased stopping distances. Dealers will correct this concern by replacing the brake vacuum line with an improved version.
The engine drive belt has a device called an idler pulley that helps to keep the belt properly aligned with the power steering pump. The bolt that secures the idler pulley may come loose, causing the drive belt to fall off and power steering assist will be lost. If this occurs, you will still be able to steer your vehicle, it will just take much more effort. Your BMW dealer will replace and properly tighten the idler pulley bolt.
The diesel fuel filter heater, which is used to warm the fuel at low temperatures, could experience an electrical overload condition and become permanently activated. The heater could remain active even when the ignition is off, which can lead to a dead battery. The unit itself could also overheat, increasing the risk of a fire. Dealers will replace the fuel filter heater to correct this concern.
The rear disc brake rotors may not have been manufactured to the proper specifications and in extreme cases, one or both rotors may break resulting in a loss of braking ability at that wheel, increasing stoping distances and the risk of a crash. Dealers will inspect the rear brake discs and replace them as necessary.
