NHTSA Complaint #11708709 — 2023 MERCEDES-BENZ EQS 580 4MATIC

My Mercedes EQS SUV has experienced repeated safety-related defects. The brakes have intermittently locked up while driving, creating a serious safety concern. The vehicle also vibrates at highway speeds on the freeway. These issues have occurred on two separate occasions. Despite multiple service visits, the dealership has been unable to diagnose or repair the problems. During the first incident, they reset the software. During the most recent incident, multiple software error warnings appeared simultaneously, indicating system malfunctions (see images for documentation). The vehicle has now been at the Mercedes service center for over two weeks, with required parts on backorder from Mercedes and no estimated repair timeline provided.
