## Narrative
My 2022 Mercedes-Benz EQS 450+ repeatedly showed "Active Brake Assist Functions Limited," "Active Emergency Stop Assist Inoperative," and Blind Spot Assist warnings, photographed by September 23, 2026. On September 24, I reported these issues and showed photos to an authorized dealer. Electronic repairs were performed, but warnings returned. The repair record lists Blind Spot Assist as "not verified"; I have no record of an Active Brake Assist test.  On October 8, while turning left across oncoming traffic, the car was in a collision. Automatic emergency braking did not activate. I know the distinctive sudden braking sensation from previous experience. I cannot determine whether activation was expected in these circumstances.  Police attended, and the insurer declared a total loss. The car is at Copart; preservation for inspection has been requested but not confirmed. Please investigate a possible safety-system defect.
