RepairPal Expert Overview
Braking power could be unexpectedly reduced increasing vehicle stopping distance.
BMW will notify owners beginning in November 2013. If you don't receive notification and you feel you should, please contact your dealer for further instruction. They may ask for your vehicle identification number (VIN), so please have it handy when you call.
These vehicles use a vacuum pump to supply power assist for the braking system. The vacuum pump can fail unexpectedly due to insufficient lubrication. This would reduce braking efficiency, increasing the risk of a crash. Dealers will make modifications to allow for proper lubrication of the vacuum pump in order to correct this concern.
