What's wrong?
The front wheel arch cover on the 2020-2021 Mercedes-Benz Glb 250 is the molded trim around the front fender opening. It helps cover the edge of the wheel opening and stays clipped to the fender while air, road spray, and vibration move around the front wheels. The part is not a drive component, but it still has to stay attached at speed.
On affected vehicles, the front wheel arch covers were not installed to current production specifications after certain assembly plant rework. If the cover is not fully seated or secured, normal driving forces can loosen it. The cover can then separate from the fender and detach from the vehicle while driving.
Before that happens, an owner can notice a gap between the wheel arch cover and the fender. That visible gap is the warning sign to mention when calling a Mercedes-Benz dealer.

What's the safety risk?

What should I do?
- Check your VIN to confirm your 2020-2021 Mercedes-Benz Glb 250 is included in this recall.
- Contact a franchised Mercedes-Benz dealer to schedule the free front wheel arch cover inspection and correction, which secures covers that detach and create a road hazard.
- Bring the recall notice if Mercedes-Benz mailed one, or reference recall number 21V232 when you call.
- Avoid driving with a loose or missing front wheel arch cover; contact the dealer before taking the vehicle in.
What happens at the repair
At the dealer, a Mercedes-Benz technician checks how the front wheel arch covers are installed on the front fenders and corrects the installation when needed. Parts and labor are covered under the recall. MBUSA is not providing a separate reimbursement notice because the involved vehicles were not previously subject to this condition and remain covered under the new vehicle warranty. If you have prior repair paperwork, ask the service desk how warranty coverage applies.
