by BMW due to an engine management software defect that may cause the brake assist to fail in particular conditions.
The issue affects 2019 to 2021 model years, as well as a 2020-2021 Toyota Supra, which is similar to the BMW Z4 roadster. Read on to learn more about the recall.
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.
In early 2021, there was an increase in warranty claims for BMW autos—which when BMW's brake assist problem became apparent. BMW conducted an internal engineering review of these claims between February and April 2021.
