BMW has issued a recall for nearly 9,000 vehicles in North America with brake vacuum pumps that can fail, causing the car to lose braking power and functionality.

According to reports, the recall scheduled for this month affects select vehicles of the following models:

2014 BMW 328i xDrive Sports Wagon

2012-’14 BMW 320i Sedan, 328i Sedan, 320i xDrive Sedan and 328i xDrive Sedan

2012-’13 BMW 528i Sedan and 528i xDrive Sedan

2013-’14 BMW X1 sDrive28i and X1 xDrive28i Sports Activity Vehicle

2013-’14 BMW X3 xDrive28i Sports Activity Vehicle

2012-’14 BMW Z4 sDrive28i Roadster

2014 BMW 428i Coupe and 428i xDrive Coupe

Vacuum pumps in the vehicles can fail due to “insufficient lubrication,” according to the National Highway Traffic Safety Administration.

Affected owners can take their vehicles into BMW dealerships for a repair free of charge, which will involve putting “a locking ring in the camshaft to retain the camshaft seal disk in the proper location,” the NHTSA said in a statement.

The announcement is said to expand on an earlier BMW recall for vehicles with problematic braking systems.

In affected models, the braking system is still operational, but the amount of pedal pressure required to stop the vehicle will be “significantly greater,” BMW said in a press statement at the time. The brake-related recall for 2012-’14 320i and 328i sedans in the U.S was part of a larger global campaign to repair 176,000 vehicles.
