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…
I am submitting this report regarding a serious and potentially fatal unintended vehicle acceleration incident that occurred immediately after my vehicle was returned from repair. I originally brought the vehicle to the dealership’s body shop following a collision. The repairs included the replacement and repair of cracked grille covers, sensors, rear damage, and the rear camera system. The vehicle remained at the repair facility for approximately one month during the repair process. After finally picking up the vehicle, I drove and tested it…
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 …
While driving, the vehicle’s lane keeping system applied an unintended and aggressive steering input during a lane change. I was merging left when the system suddenly forced the steering sharply to the right without driver command. This was not a gentle correction, it was a strong, unexpected movement that could have caused a collision if another vehicle was nearby. In addition, the vehicle has ongoing intermittent ADAS malfunctions, including false forward-collision warnings, proximity sensors activating with no obstacles present, and Park Ass…

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…

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.
