BMW recalls 76,000 cars due to possible power brake failure

September 29, 2013
BMW has announced a voluntary recall of 76,190 2012-14 cars over fears of a possible loss of power braking. Units affected include 3-Series, 5-Series, X1, X3, and Z4 models  built between May 2012 and August 2013 and equipped with the N20 or N26 turbo four-cylinder motors.

According to the recall bulletin on F30post, the issue stems from a potential restriction of oil supply from the intake camshaft to the vacuum pump. If that pump were to fail, the driver would experience a sudden loss of power braking assist. Applying normal pressure to the brake pedal would then result in vastly increased braking distances.

BMW is already aware of three accidents due to this problem, all on low-mileage cars. Additionally, the National Highway Traffic Safety Administration has received seven reported incidents.

Though there is not a fix at this time, BMW is reportedly working on a solution involving a locking ring inserted onto the camshaft so that oil flow to the vacuum pump remains unimpaired. 

For now, BMW recommends that you continue to drive your vehicle until the recall notice is sent to owners in December. The two-hour fix will be conducted free of charge. However, if drivers experience any loss of braking ability BMW recommends that they pull over immediately.
