While traveling at highway speeds with adaptive cruise control safety systems engaged, the vehicle failed to detect a hazard immediately ahead in its lane. The Forward Collision Warning failed to alert the driver, and the Automatic Emergency Braking (AEB) failed to initiate automated emergency deceleration. Manual emergency braking was attempted by the driver in the final milliseconds, but the vehicle's braking system failed to sufficiently decelerate the vehicle, resulting in a high-energy frontal collision. Despite severe structural deformation concentrated entirely on the front fascia and crumple zones, the Supplemental Restraint System (SRS) completely failed and no airbags deployed. The driver sustained injuries to the neck, back, and ribs. The vehicle has been declared a total loss by insurance and is available for inspection at a salvage facility. The manufacturer was notified over a month ago (Case #21986205) but has failed to pull the Event Data Recorder (EDR) telemetry or provide an engineering review timeline. No prior warning lamps or system malfunction messages were present before the incident.

The car will apply electronic parking brake when put into park. If the brake is wet due to rain and the car sits overnight or for 12 hours or more, the brake sticks to the rotor. The brake will not release unless you press down on the accelerator creating a safety hazard as the car will jerk forward or in reverse. I've raised this with the MB dealer and service technician and they confirm the this Amy happen and that there is no fix. This situation creates a serious hazard.
