2012 BMW X5 xDrive Recalls
The bolts that secure the housing for the variable camshaft timing adjustment unit can loosen over time and possibly break, causing engine damage and engine stalling. Dealers will replace the four bolts for both intake and exhaust timing units free of charge to resolve the concern.
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.
Certain 2012 X5 models equipped with a diesel engine, and a number of 2013 X5 and X6 models, may develop a power steering fluid leak from the steering gear. This leak is due to a machining error on the steering gear. Leaking power steering fluid can spray onto hot exhaust parts, increasing the risk of an engine compartment fire. Dealers will inspect and replace the steering gear as necessary on affected vehicles.
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.
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 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.
