Vehicles Affected: Approximately 470 model-year 2018 Mercedes-Benz E300, E300 4Matic and E400 4Matic sedans; model-year 2018 E400 and E400 4Matic cabriolets; model-year 2018 CLA250 and CLA250 4Matic coupes; model-year 2019 CLS450 4Matic coupes; model-year 2018 Mercedes-AMG E43 4Matic and E63S 4Matic Plus sedans; and model-year 2018 CLA45 4Matic coupes
The Problem: In all but the cabriolets, the occupant classification system may not be properly calibrated, resulting in the front passenger airbag not being deactivated if a child seat is in the front seat.
In the cabriolets, the Latch system may not have been properly installed. As a result, in the event of a crash, the Latch console may partially detach from the car body. Both defects increase the risk of injury.
The Fix: For the occupant classification system defect, dealers will replace the front passenger seat cushion. For the Latch system, dealers will inspect the Latch console and replace it if necessary. Both repairs will be done for free.
What Owners Should Do: Mercedes-Benz will begin notifying owners Oct. 3. Owners can call the automaker at 800-367-6372, the National Highway Traffic Safety Administration's vehicle-safety hotline at 888-327-4236 or visit its website to check their vehicle identification number and learn more.
