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
Per Daimler Trucks North America Campaign "22V281 & 22V232": The function of the rearview camera might be impaired where the rearview image might not be displayed in the central display after reversing. Instead, the central display would continue to display the existing image or display a black screen with a message indicating the inoperability of the rearview camera system. In addition, the rearview camera image neither freezes nor deactivates. As the vehicle begins to back up, a rearview camera image under these conditions might impair rear visibility, which could increase the risk of a crash. When the issue occurs, the driver might notice that the central display would either continue to display the existing image or display a black screen with a message indicating the inoperability of the rearview camera. Unfortunately, the parts to remedy this are not yet available. We are working to obtain the necessary parts to correct this condition as quickly as possible. As parts become available, we will send you another letter asking you to take your vehicle to an authorized Mercedes-Benz dealer to have the recall completed free of charge.
