Known issues on the 2025 GLB250. NHTSA records two recalls for the 2025 GLB250. In the first, the right-side front and rear tires may have sidewall damage that can cause a sudden loss of tire pressure; dealers inspect the tires and replace them as needed (campaign 24V780000). In the second, the micro-switch in the driver's door lock can corrode and fail to detect an open door, so the automatic parking brake and Auto-Park may not engage and the vehicle could roll away; dealers replace the driver's door lock (campaign 26V481000). One owner complaint is recorded, citing the electrical system, the service brakes and forward collision avoidance. Tire and wheel specifications, the door lock and the mild hybrid circuits are all covered.
