The problem
Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2017 AMG GT & AMG GT-C Roadster and 2018 AMG GT-S & GT Roadster vehicles equipped with AMG Performance Seats. The passenger occupant classification system (OCS) might not function properly, possibly causing the passenger frontal air bag to be incorrectly deactivated or incorrectly activated in the event of a crash.
The risk
A passenger air bag that is incorrectly activated or deactivated in the event of a crash increases the risk of injury due to potential incorrect airbag deployment or non-deployment.
The fix
MBUSA will notify owners, and dealers will update the OCS software, and if necessary, replace the passenger seat cushion, free of charge. Owners will be notified of the recall in January 2018 and they will receive a second letter when the parts become available, currently expected to be in February 2018. Owners may contact MBUSA customer service at 1-877-496-3691.
