The recall covers 76,200 vehicles sold in the U.S. Affected models include 2012-14 BMW 320i and 328i sedans;, 2014 328i xDrive sports wagons; 2012-13 BMW 528i sedans 2013-14 BMW X1 sDrive28i and X1 xDrive28i; 2013-14 BMW X3 xDrive28i, and 2012-14 BMW Z4 sDrive28i.
The company says owners will be notified by mail to bring their cars in for repair.
BMW says that if brake assist power is lost, drivers should pull over and call roadside assistance.
