Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.

Service Bulletin/Repair Instructions
According to the Interim Recall Notice Received by Mercedes-Benz concerning 22V796: "Mercedes-Benz AG has determined that on certain Sprinter vehicles, a component of the park lock system might wear extraordinarily due to specific driver parking practices and impair safe parking of the vehicle. If the vehicle is not properly secured in accordance with parking instructions in the operator's manual (including usage of the parking brake), it cannot be ruled out that the vehicle might roll away from its parked position under certain circumstances. Thus, the risk of an accident could increase. The driver will not receive a warning due to the nature of the failure mechanism. It is important that the driver ensures that the manual parking brake is engaged to adequately secure the vehicle against rolling away. Additionally, the parking level "P" is only to be inserted when the vehicle is completely stationary. The customer can find precise information on the parking process and on correct vehicle securing in their operator manual. Owners who notice any issues with the automatic transmission park lock function may contact their nearest Mercedes-Benz service partner immediately and have an appointment arranged for the vehicle to be inspected."

As per Mercedes-Benz Recall 2020-545; MBAG has determined that on certain Mercedes-Benz Sprinter vehicles, the hydraulic power steering return line hoses might detach at their connection points under certain operating conditions, which could cause hydraulic fluid to leak, resulting in the loss of power steering assist. If the hydraulic power steering hose detaches, the driver will still have manual steering functionality, but increased steering effort will be needed, particularly at low speeds. Sudden loss of power steering assist as well as the loss of hydraulic steering fluid to the road surface may increase the risk of a crash.
