Vibrations from driving may cause the nut to loosen, allowing the wheel to separate from the car. If the spare wheel separates from the vehicle, it could become a road hazard and increase the risk of a crash.
A non self-locking nut may have been used to secure the spare wheel under the car. If this is the case, vibration from driving can cause the nut to loosen allowing the wheel to fall off. The wheel would become a road hazard, increasing the risk of a crash. Dealers will replace the nut securing the spare wheel with a self-locking nut to correct this concern.
BMW will notify owners of affected vehicles beginning November 2014. If you don't receive notification in a timely manner and believe you should have, please contact your BMW dealer for further instruction. They may ask for your vehicle identification number (VIN), so please have it handy when you call.
