Known issues on the 2021 GLB35 AMG. NHTSA lists eight recalls for certain 2021 GLB35 AMG vehicles. The most mechanical involves the integral carrier supporting the front axle on certain vehicles, which could corrode until it failed and took steering control with it; dealers inspect and replace the carrier as needed. Another found that on certain vehicles the driver-side window airbag might not be mounted properly at the lower A-pillar, so it might not protect as intended. On certain vehicles, a corroded switch in the driver's door lock could also miss an open door, keep the parking brake or Auto-Park from setting and let the SUV roll away. Owners filed 5 complaints, including wheels, visibility/wiper and hydraulic brakes. Front axle torque values, airbag procedures and wiring diagrams are covered.
