Vehicles equipped with an 8 or 12 cylinder turbocharged engine may overheat the circuit board for the auxiliary water pump. This could lead to smoldering of the pump or an engine compartment or vehicle fire. Dealers will replace the auxiliary water pump to correct this concern.
The insulated 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. Loosening of the connection can cause an increase in electrical resistance and overheating of the cable connection, which could lead to a fire, even when the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been completed. Dealers will secure the battery bolt cable connection as necessary to correct this concern.
Due to a manufacturing error, six vehicles may have a condition where the engagement of the transmission's parking lock may not occur when the shifter is in the "P" position. In this situation, if the parking brake is not applied, the vehicle could roll unexpectedly, increasing the risk of a crash. Dealers will replace the automatic transmission to correct this concern.
On vehicles equipped with an 8 or 12 cylinder turbocharged engine, the circuit board for the electric water pump may overheat. This could lead to smoldering of the pump and/or an electrical fire in the engine compartment. Dealers will replace the auxiliary water pump to correct this concern.
The front driveshaft attachment bolts may not have been tightened to specification and could become loose. This could lead to a loss of power to the front wheels and ultimately a vehicle breakdown, increasing the risk of a crash. Dealers will replace the front driveshaft attachment bolts to correct this concern.
High resistance in the electrical contacts may cause one or more of the rear lights to stop working. Intermittent light operation reduces the ability to warn other motorists of the driver's intentions, increasing the risk of a crash. Dealers will repair the affected vehicles as necessary to correct this concern.
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.
Fifty vehicles may have a control module in the electric power steering (EPS) unit that could malfunction, resulting in a sudden loss of power steering assistance. Sudden loss of power steering assistance could increase the risk of a crash. Dealers will perform the repairs necessary to correct this concern. This recall is expected to begin during July of 2011.
On vehicles equipped with a diesel engine, the drive belt tensioner may have been manufactured incorrectly; the welds in the tensioner may crack. Over time, this could lead to failure of the tensioner. Belt tensioner failure could result in the sudden loss of power steering assist, increasing the risk of a crash. Dealers will replace the engine drive belt tensioner to correct this concern. This recall is scheduled to begin during June of 2011.
The fuel level sensor is the sensor located in the fuel tank that tells the vehicle how much fuel is in the fuel tank. This sensor has a float attached to it that may become wedged against the fuel tank, causing the float to be stuck in one spot instead of "floating" on top of the fuel in the tank. Because the float can not move, the instrument cluster will indicate that the fuel level is still full, even though it empty. Running the vehicle out of fuel will result in the vehicle shutting off (stalling) while driving down the road. BMW will replace the fuel level sensor free of charge. If you own a 2010 or 2011 5-series and did not receive a notice, contact BMW at 1-800-525-7417 or the national highway traffic Safety Administration at 1-888-327-4236 to verify this recall does not apply to your vehicle. You may need the Vehicle Identification Number (VIN), located on a placard attached to the vehicle's driver side door frame. Your vehicles production date is also on this placard.
