Just under 30,000 X5 xDrive 35d SAV diesel vehicles of the 2009 through 2012 model years have been recalled by BMW. The recall was necessitated once it was discovered that loosening of the engine belt idler pulley bolt could occur. This might lead the component to break completely given enough time. A vehicle experiencing such a break would be in danger of losing its power steering, potentially leading to a crash situation. At some point in January, the recall will likely begin, at which point affected owners can expect to receive word of the issue from BMW. Free repairs will consist of replacement and tightening of the affected vehicle component.
