Mercedes-Benz vehicles recalled for faulty rear seat belt retractors

Mercedes-Benz is recalling certain 2021-2022 vehicles because rear seat belt automatic locking retractors may deactivate early, preventing child restraint systems from securing properly. An unsecured child restraint increases the risk of injury during a crash.

What this means for you

Our assessment, not the agency’s: severity 3/5 (High).

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: This recall involves a structural vehicle defect affecting child safety systems. Although no injuries or deaths have been reported, the hazard is significant because an unsecured child restraint system poses serious injury risk during crashes. Per the rubric, risk-of-harm products without reported injury score High (3).

Plain-English summary

Mercedes-Benz is recalling certain 2021 and 2022 vehicles including the G550, E350, E450, CLS450, AMG G63, AMG GT63, AMG GT53, AMG GT43, AMG CLS53, AMG E53, and AMG E63. The rear seat belt automatic locking retractors in these vehicles may deactivate early, which can prevent child restraint systems from securing properly.

Dealers will inspect and replace the rear seat belt assemblies at no charge. Owners were notified of the recall by interim letter on August 13, 2021, and a final letter on September 24, 2021.
