What's wrong, in plain English

Some AMG GLB35, A220, and GLB250 vehicles have a part called the integral carrier that supports the front axle. Over time, this part may corrode and eventually fail. If the carrier fails, the driver could lose steering control, which increases the risk of a crash.

What you should do

1. Check your VIN at nhtsa.gov/recalls to see if your vehicle is affected. 2. Contact a Mercedes-Benz dealer, or call MBUSA customer service at 1-800-367-6372. 3. Inspection and replacement of the carrier, if needed, is free.

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 21V990000.
