The ABS module, which controls the brake drying feature, is malfunctioning. This BMW feature is designed to lightly pulse the brakes when the windshield wipers are active to wipe water off the rotors for better braking performance. The intervention is supposed to be imperceptible. Instead, the system intermittently applies hard, sudden brake pressure while the windshield wipers are operating. This causes abrupt, strong deceleration that feels like the brakes are slamming on by themselves. The problem occurs in wet conditions when wipers are on. It has happened multiple times and has nearly caused rear-end collisions or loss of control on multiple occasions. This unexpected hard braking at speed in wet conditions creates a significant risk of rear-end collision, loss of vehicle control, or accident, especially on highways or in traffic. The only workaround is to drive without wipers in the rain, which is also dangerous due to reduced visibility. I have not yet brought the car into the dealership to have it inspected but I do intend on getting that done within the week. There are no warning lights or messages to suggest there even is a problem.
