What's wrong?
The driver's air bag module in the 2021 Mercedes-Benz Glb 250 is the unit inside the steering wheel that inflates the driver's air bag during a crash. It has to match the steering wheel, vehicle configuration, and market equipment so the air bag deploys with the right shape, timing, and force for that vehicle.
On affected Glb 250 vehicles, the wrong front driver's air bag module was installed during production rework. Mercedes-Benz traced the issue to a production deviation, where air bag modules from different vehicles were interchanged during steering wheel replacement work. The installed module does not meet current production specifications for the vehicle. That mismatch means the driver air bag is not confirmed to perform as designed if it has to deploy.
There is no warning sign before failure. The driver will not see a warning light or message tied to the incorrect air bag module before the vehicle needs the recall repair.

What's the safety risk?
An incorrect driver air bag module can fail to restrain the occupant properly in a crash, or detach from the steering wheel during deployment. Either failure increases injury risk in a crash. There is no warning sign before the air bag fails to work correctly, so confirm by VIN and schedule the inspection soon. Repair is free at any franchised Mercedes-Benz dealer.

What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the front driver's air bag module and replaces the air bag if it is the incorrect module covered by the recall. The inspection, replacement part, and labor are free under the recall. Out-of-pocket repairs already paid are handled through the new vehicle warranty, not through a separate reimbursement program, since the involved vehicles remain under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
