A recently-posted BMW AG report on the National Highway Traffic Safety Administration (NHTSA) website has revealed that the luxury-car maker is recalling nearly 30,000 of its diesel-powered 2009-12 X5 sport utilities due to issues with the power-steering systems of the vehicles.

According to the BMW document field with the NHTSA, the vehicles which are being recalled by the automaker include the X5 xDrive 35d vehicles manufactured in the period from between September 1, 2008 and November 15, 2012.

About the potential power-steering problem leading to the recall, BMW said in the document that the engine idler pulley of the affected vehicles can loosen over time, thereby increasing the chances of its breakage. If the mentioned part breaks, the vehicle's power-assist for its steering can fail, thus making the vehicle difficult to turn and putting it at an increased risk of a crash.

Though BMW has mentioned in the document that there have thus far been no reports of crashes or injuries because of the engine idler pulley, the company also said that the recall of the vehicles has been prompted by an earlier-this-year probe by Transport Canada, the NHTSA's Canadian counterpart.

Revealing that the owners of the affected diesel-powered X5 sport-utility vehicles (SUVs) will be notified about the power-steering issue next month, BMW said that the dealers will replace and tighten the idler pulley bolt in the under-recall vehicles.
