Airbags Vehicle recall #19V352000 · 2019 · 5,079 vehicles
What's wrong: The driver and passenger knee air bag assemblies May have been improperly folded and assembled.
Why it matters: An improperly folded and assembled air bag May not deploy as intended, increasing risk of injury.
The fix: Bmw will notify owners, and dealers will replace the knee air bag modules, free of charge. The recall began July 8, 2019.
Fuel system Vehicle recall #20V666000 · 2020 · 21 vehicles
What's wrong: Fuel injectors May have been installed without a damping component which is used to reduce vibration. If a damping component is not present, vibration will increase at the connection between the fuel line and the fuel rail, which over time, can result in damage at the connection.
Why it matters: A damaged connection between the fuel line and the fuel rail could lead to a fuel leak and, in the presence of an ignition source, increase the risk of a fire.
The fix: Bmw will notify owners, and dealers will inspect the fuel injectors and if a damping component is missing, the injectors and the fuel rail will be replaced, free of charge. The recall began December 18, 2020.
