Defect
BMW of North America, LLC (BMW) is recalling certain model year 2015-2016 M3 Sedan vehicles manufactured May 30, 2015, to September 2, 2015, 2016 M4 Coupe vehicles manufactured July 3, 2015, to September 11, 2015, and 2015-2016 M4 Convertible vehicles manufactured May 29, 2015, to August 4, 2015. The affected vehicles have a driveshaft with a slip-joint that may not have been filled with grease. As a result, the slip-joint may fail over time.
Safety Risk
If the slip-joint fails, there would be a loss of power to the rear axle and therefore the vehicle would stop moving, increasing the risk of a crash.
Remedy
BMW will notify owners, and dealers will inspect the driveshaft, replacing it as necessary, free of charge. The recall began on January 14, 2016. Owners may contact BMW customer service at 1-800-525-7417.
