Defect
Mercedes-Benz, LLC (MBUSA) is recalling certain 2021 G550, AMG G63, E350, E450, AMG CLS53, AMG E53, AMG GT43, AMG GT53, AMG GT63, 2021-2022 CLS450, and AMG E63 vehicles. The rear seat belt automatic locking retractors may deactivate early, which can prevent the child restraint system from securing properly. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, "Occupant Crash Protection."
Safety risk
An unsecured child restraint system can increase the risk of injury during a crash.
Remedy
