Mercedes-Benz is recalling certain 2019-2022 CLS450 Coupe and AMG E53, 2019-2021 AMG CLS53 Coupe, and 2021-2022 E450 cars. Dealers will secure the battery at no charge.

Where do I find my VIN, and what do I tell the dealer?

Your VIN is the 17-character code on the lower left of the windshield, on your registration and usually on your insurance card. 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 22V733000.
