The 2020 BMW M4 has two recalls, the more serious being a fuel injector assembly missing a vibration-dampening component that can cause the fuel line connection to wear and crack over time, creating a fuel leak and fire risk.
The second recall involves the driver and passenger knee airbags, which may have been improperly folded during assembly. If either airbag deploys in a crash, it may not open correctly, reducing the protection it provides to the occupants' legs and knees.
