What's wrong, in plain English
Mercedes-Benz is recalling a number of 2021 and 2021-2022 models, including the G550, E350, E450, CLS450 and several AMG versions. The rear seat belts have a locking feature used to hold a child seat tightly in place. That lock may switch off too early, which can keep the child seat from being held securely. Because of that, these vehicles do not meet the federal rule on protecting people in a crash. Dealers will check the rear seat belts and replace them if needed.
What you should do
2. Contact a Mercedes-Benz dealer to have the rear seat belts inspected. MBUSA customer service is 1-800-367-6372.
3. The inspection and any replacement are free of charge.
Where do I find my VIN, and what do I tell the dealer?

Enter it at nhtsa.gov/recalls to see whether this recall is still open on your car. When you call the dealer, say you have an open safety recall and give them NHTSA campaign number 21V483000.
