BMW North America has announced a voluntary recall to the National Highway Traffic Safety Administration for several of their models for possible brake failure. Although there has not been any formal notice from the NHTSA, BMW plans on moving forward with recalling over 76,000 of their 2012-2014 BMW 3 and 5 Series sedans, X1 and X3 crossovers, and the Z4 roadster. All of the recalled vehicles are equipped with either the N20 or N26 six-cylinder engine, and most of them are also equipped with the xDrive all-wheel drive system. All of the vehicles were produced from May 2012, through August 2013.
The recalled vehicles are as follows:
2012-14 320i/328i, 320i/328i xDrive Sedan manufactured between May 2012 – August 2013
2014 328i xDrive Sports Wagon manufactured between March 2013 – May 2013
2012-13 528i, 528i xDrive Sedan manufactured between June 2012 – June 2013
2013-14 X1 sDrive28i, X1 xDrive28i manufactured between June 2012 – June 2013
2013-14 X3 xDrive28i manufactured between June 2012 – August 2013
2012-14 Z4 sDrive28i manufactured between June 2012 – June 2013
The root cause of the brake failure is due to the limited amount of oil that is able to travel from the intake camshaft to the brake vacuum pump. This could lead to the failure of the pump, which in turn could lead to the loss of the power brake assist. The loss of the assist could increase the risk of the vehicle being involved in an accident.
Although BMW has reported that there have been three minor accidents as a result of the defect, there have not been any confirmed reports of any injuries occurring. Moreover, it is being recommended that if anyone experiences brake failure, to slowly pull up on the handbrake lever, while applying as much pressure to the brake pedal as possible. Also, if the vehicle is equipped with an electronic parking brake, it is recommended that the driver pull up and hold the switch to engage the parking brake, also while applying pressure to the brake pedal. Once the vehicle has been brought to a complete stop, the driver should contact BMW Roadside Assistance via the BMW Assist button, in order to have the vehicle towed to an authorized BMW dealership.
Although there hasn't been a repair solution to the latest BMW recall, the Bavarian automaker intends to contact the registered owners in November of the defect.
