As with many recent recalls, the problem is a software error, and in this case a software error in the hand detection control unit. Mercedes says the hands-off detection might not detect when the driver's hands are away from the steering wheel when using the Active Distance Assist DISTRONIC system.
Mercedes opened an investigation in June 2021 based on internal test driving which showed the hands-off detection on a specific steering wheel did not work properly. Mercedes and the supplier opened an investigation and determined a software update could allegedly repair the problem.
A driver may not receive a warning message to grab the steering wheel, and in an emergency involving the driver, the vehicle will continue to drive without triggering the Active Emergency Stop Assist.
Mercedes says in addition to not stopping, the vehicle won't place an emergency call and the driver will have no advance warning of a problem.
Mercedes dealers will update the hand detection control unit software for the DISTRONIC systems once owner notification letters are mailed May 20, 2022.
