What's wrong, in plain English
This recall affects certain Mercedes-Benz AMG CLS53, AMG E53, and AMG G63 vehicles. The connectors for the side-impact crash sensors may come loose. If that happens, it could delay the airbags and seatbelts from activating the way they're supposed to during a side crash, which means they may not respond as quickly as needed when the vehicle is hit from the side.
What you should do
2. Contact a Mercedes-Benz dealer, or call MBUSA customer service at 1-800-367-6372.
3. The repair is free.
