The issue affecting more than 50,000 BMW SUVs and cars

If you own a BMW vehicle affected by the recall and you find yourself without braking assist while on the road, understand that stopping distances will be longer. Also, in such situations, pressing harder on the pedal to stop the automobile is advisable.

Additionally, BMW says that the affected auto's engine management software can damage the oil/vacuum pump supplying the vacuum that enables the brake assist function in certain starting conditions. The following conditions can impact the system:

Depressing the brake pedal briefly while pressing the engine start/stop button.

Pressing the engine start/stop button two times in rapid succession will also affect the brake assist system.

Although both situations can eventually lead to the loss of brake assist, BMW indicates that the full brake assist function remains available for about six partial brake applications or about two to three full brake applications.

Fortunately, the automaker has said it’s not aware of any crashes relating to the brake assist system failure.
