What's wrong?
The integral carrier on these 2019-2021 Mercedes-Benz AMG GLB35, Glb 250, and A 220 vehicles is a structural front-axle support. It helps hold the front suspension and steering attachment points in the correct position, so the front wheels stay aligned with steering input and road loads.
On affected vehicles, a supplier production deviation left certain integral carriers with corrosion protection that was below Mercedes-Benz specifications. Once that protection is not strong enough, corrosion attacks the carrier and reduces its strength. If the carrier fails, the front axle support no longer does its job as designed.
There is no warning sign before failure. The driver does not receive an alert or a clear symptom because of the way this part fails.

What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the integral carrier that supports the front axle and replaces it as needed. The recall repair is free, with parts and labor covered. Out-of-pocket repairs already paid are handled through the new vehicle warranty, not through a separate reimbursement program, because the involved vehicles remain covered under that warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
