The Valve body control failed. I took the car into the dealership but upon doing some searching this seems to be a common issue amongst owners of this vehicle/make model.

It required the engine shutting on/off multiple times and only then does it go into 3rd gear, causing the vehicle to jump due to missing gears. This issue could leave an owner stranded at any time and cause injury due to the limitations of the gears. It was inspected and confirmed behavior by Mercedes in Durham NC. There were no warning lamps, there were no signs of the issue. The technician did plug it in and was able to read the fault codes but it didn't trigger a light. The appeared first about 45 days ago, and the vehicle was taken in to be looked at 7/21/25.
