BMW has announced the recall of certain 2012 model year X5 Diesel SUVs, as well the recall of certain 2013 X5 and X6 models. All were built between April 20, 2012 and May 29, 2012, and BMW estimates that 2,642 vehicles are affected by this voluntary recall.

At issue is the machining of the steering gear housing, which was not within BMW’s published specifications. As a result, power steering fluid can leak into the rubber boot surrounding the steering gear, eventually leading to the loss of power steering assist and the increased risk of fire if power steering fluid leaks onto hot exhaust components.

A loss of power steering assist still leaves the driver with steering control, although a higher degree of effort is required. A change in steering effort could increase the likelihood of an accident under certain conditions.

The issue was discovered during extreme steering testing at BMW’s Spartanburg, South Carolina assembly plant, and BMW is unaware of any customer incidents relating to this defect.

The recall is expected to begin in July, and BMW dealers will inspect and replace the steering gear on affected vehicles as necessary. Owners with questions or concerns can contact BMW’s customer relations department at (800) 525-7417.

Recall updates are also available from the National Highway Traffic Safety Administration’s Vehicle Safety Hotline, which can be reached at (888) 327-4236.
