THE VEHICLE MODEL IS KNOWN TO FAIL AT THE CRANK HUB. BMW REFUSES TO ACKNOWLEDGE AND MAKE NECESSARY REPAIRS AT NO COST. IT HAS BEEN KNOWN TO HAPPEN RANDOMLY, EVEN JUST DRIVING IN A PARKING LOT. IF THIS WERE TO HAPPEN GOING AT HIGHWAY SPEEDS, IT CAN POTENTIALLY LEAD TO DEVASTATING CONSEQUENCES NOT ONLY FOR THE DRIVER AND PASSENGERS OF THE BMW, BUT AS WELL AS TRAFFIC SURROUNDING THE VEHICLE.

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.…

Emerging complaint spikes

Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.

This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.

No complete months meet the spike thresholds for this selection.
