When it comes to massive recalls, it’s not that often that you hear about BMW issuing one, but recent news says it does happen.

The latest mishap involves some 176.000 units, all fitted with BMW’s 2.0 liter, four cylinder engine.

Affected models include the 2012-2014MY 320i, 328i, 320i xDrive, and 328i xDrive sedan, the 2014MY 328i xDrive sports wagon, the 2012-2013MY 528i and 528i xDrive sedan, the 2013-2014MY X1 sDrive28i, the X1 xDrive28i and finally the 2012-2014MY Z4 sDrive28i roadster.

Along with the massive world-wide recall, the Bavarian car maker also released an explanation of the issue on affected models. “An oil plug in the intake camshaft may become displaced, restricting oil supply to the vacuum pump. Due to insufficient lubrication, the vacuum pump that supplies brake power assistance may fail. A failure of the brake vacuum pump results in a reduction in braking power that could increase the risk of a crash”.

While any brake system issue can’t be regarded as unimportant, so far, no incidents involving an affected BMW unit was reported.
