CRITICAL SAFETY DEFECT: Recurring automated ADAS sensor failure causing maximum-force phantom braking without warning or driver input. VEHICLE IDENTIFICATION: 2023 Mercedes-Benz EQS 450 4MATIC SUV (VIN: [XXX]). CHRONOLOGY OF LATEST INCIDENT: On Wednesday, XXX, at approximately 7:20 a.m. MT, I was driving eastbound on [XXX]. A few yards after passing directly under the Lite Rail underpass, and before entering the right lane to turn onto [XXX], the vehicle abruptly and violently engaged its brakes at full emergency force. The speed was approximately 20â30 mph. Weather was clear, daylight, with dry road conditions. DESCRIPTION OF PERFORMANCE: The vehicle executed full deceleration to a…

Visibility/wiper
The center console display (MBUX) on this 2023 EQS 450 4MATIC fails while the vehicle is in use. There is no warning lamp, chime or message first. Sometimes it flickers on and off; other times it goes fully blank and stays blank, unresponsive to touch. Owner video shows the display working and then completely blank 0.4 seconds later. When the screen is blank the rearview backup camera is unavailable. Selecting reverse produces no image at all. The rear camera image appears only on that center screen, so the failure removes the rear visibility required by FMVSS 111 and leaves the driver reversing with no camera view in parking garages, driveways and residential streets. An authorized…

Odometer Fraud. The contact leased a 2023 Mercedes-Benz EQS 450 X4. The vehicle was a dealer sale. After returning the lease vehicle to the dealer, he was informed the odometer closure was not available during the drop-off and it would be emailed. The contact stated that the vehicle was returned with the mileage at 17,000. The inspection report also indicated that the odometer reading was 17,000. The contact received a bill that indicated that the mileage was 7,000. The finance office was contacted, and they informed him to return to the dealer. The dealer indicated that the discrepancy was not his problem. The police were contacted, and a report was filed.

Forward collision avoidance › Automatic emergency braking
Several times, the car's "panic braking" has randomly slammed the brakes and tightened the seat belt. After the first few times, I took it to Mercedes and they re-uploaded software which was hard for them for some reason. It fixed the problem. Luckily, I had always been on small streets. But today, the panic braking happened again, only this time, I was on a major road (4 lanes at 35 mph) and, with nothing around me, no cars in front of me, the panic braking and seatbelt tightening happened so violently that I was thrust forward with enough force to hurt my hip. Nothing severe no doctors needed. I will take it back into Mercedes for another review but what if there had been someone behind…

Electrical system
While the vehicle was stationary and connected to a DC Fast Charging station (Electrify America), a thermal event occurred at the charging interface. The charging connector overheated and thermally fused (welded) to the vehicle's high-voltage charging inlet. The connector could not be released by the vehicle or the station. A technician dispatched by the charging network was unable to remove the connector using standard release protocols. The technician confirmed the equipment had failed and was forced to use physical leverage to pry the fused connector off, resulting in the fracture of the vehicle's charging receptacle. I couldn't charge the vehicle anymore and so I took it to the Mercedes…

My panoramic sunroof shattered with no warning and no apparent impact. It exploded outward, while traveling at a high speed on the highway. It was late and there were no other vehicles on the road at the time. I was not near an overpass.
