I am reporting a recurring transmission/drivability issue with my 2024 Mercedes-Benz S580. The vehicle has been experiencing a harsh, abnormal shift between approximately 3rd and 4th gear at around 25–35 mph during normal acceleration. The shift feels like a sudden jerk or hesitation and does not feel consistent with normal operation. The vehicle has been taken to an authorized Mercedes-Benz dealership multiple times for this issue. On a recent visit (February 9, 2026), a drive technician rode along and personally experienced the harsh shifting during a test drive. The dealership later confirmed in writing that the harsh shift was duplicated and documented on the repair order. Despite prior service visits, the problem continues to occur intermittently. It has happened again after the most recent service. In addition to the shifting concern, the vehicle has previously experienced power-related issues and steering/driver-assist warnings. There are not always warning lights before the harsh shift occurs. The vehicle remains available for inspection. Because the shifting happens during normal acceleration at city speeds, it feels unpredictable and concerning from a safety standpoint.
