Description
Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2021-2022 C-Class, E-Class, S-Class, SL, EClass Coupe/Convertible, CLS, AMG GT 4-doors Coupe, and EQS vehicles with a heated leather steering wheel. Due to a software error in the hand detection control unit, 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.
Issue
Deactivated hands-off detection will prevent DISTRONIC system features from functioning, including warnings to grab the steering wheel and calling first responders as part of the Active Emergency Stop Assist, which can increase the risk of a crash or injury.
Consequence Summary
Deactivated hands-off detection will prevent DISTRONIC system features from functioning, including warnings to grab the steering wheel and calling first responders as part of the Active Emergency Stop Assist, which can increase the risk of a crash or injury.
Corrective Action
Dealers will update the hand detection control unit software for the DISTRONIC system, free of charge. Owner notification letters were mailed May 6, 2022. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2022040010.
