What's wrong?
The front wheel well area on the 2020 Mercedes-Benz Glb 250 sits around the front tires and is supposed to keep road spray out of the cabin. Body sealant in that area closes gaps between metal panels so water stays outside the front foot wells, where wiring and electrical components are located.
On affected Glb 250 SUVs, the vehicle body was not sealed to Mercedes-Benz production specifications. Water can enter through the front wheel well area and collect in the front occupant foot wells. Once water reaches electrical components, the instrument cluster can go blank, or the engine can stall while driving and fail to restart.
Owners can notice wet carpets in the front foot wells or fogged windows. Those signs point to water intrusion and should be treated as a warning that the sealing problem is already allowing moisture into the cabin.

Not every 2020 Mercedes-Benz Glb 250 is on the list. Check your VIN to confirm whether your specific SUV is included.
What's the safety risk?
A blank instrument cluster display can hide critical driving information, and an engine stall increases crash risk. If you notice wet front carpets or fogged windows, schedule service soon and drive cautiously until the dealer checks the vehicle. Repair is free at any franchised Mercedes-Benz dealer.
What should I do?
- Check your VIN to confirm your 2020 Mercedes-Benz Glb 250 is included in this recall.
- Contact a franchised Mercedes-Benz dealer to schedule the free wheel-well sealing and front foot-well inspection that addresses water intrusion tied to a blank instrument cluster or engine stall.
- Bring the recall notice if Mercedes-Benz mailed one. If not, reference recall number 20V246 when you call.
- Drive cautiously until the repair is complete. Pull over safely if the instrument cluster goes blank or the engine stalls.
What happens at the repair
At the dealer, a Mercedes-Benz technician seals the vehicle body in the wheel well area, then inspects the front foot wells for water intrusion. If water has damaged covered parts, the dealer repairs what is needed under the recall. Parts and labor are free. Out-of-pocket repairs already paid are handled through the new vehicle warranty, not through a separate reimbursement program, because the involved vehicles remain under warranty. Ask the service desk how that warranty coverage applies to prior repair paperwork.
