The 2021 BMW M440i has 5 recalls, the most serious being a fire risk from increased electrical resistance in the battery system, alongside an airbag that may fail to deploy correctly in a side-impact crash, raising the risk of injury.
The seatbelt system has two separate concerns. The seatbelt retractor on certain vehicles can fail to function as intended during a crash, which means the belt may not restrain the occupant properly when it matters most. Separately, a software issue in the audio module can cause the audible chime that reminds the driver to buckle up to stop working, removing a basic safety prompt before the vehicle is even moving. On the visibility side, the rearview camera can display a reduced or missing image while reversing, leaving a driver who depends on that view without a clear picture of what is behind the vehicle.
