BMW X4 (16/04/2018 – 08/06/2018) RECALL: The fault affects the brake system, in particular, the brake callipers on the rear axle. Because of a faulty coating, hydrogen gas (approximately 10 ml) could be created in the coating of the piston of the brake calliper. This will be completely outgassed during the first 2 months after the production process, causing longer brake pedal travel. Under certain circumstances, the relevant brake pressure cannot be build up in the rear brake circuit. As a result, the brake force of the system may be reduced by up to 30%. The driver may feel a soft brake pedal and a reduction of the brake performance. In certain cases, the rear brake circuit could fail, leading to increased risk of an accident.
Remedy
On the affected vehicles the brake system will be bled.
