The 2021 BMW M440i has 5 recalls, the most serious being two safety issues: a seat belt retractor that may not function properly in a crash, and a battery connection that can develop high electrical resistance and raise the risk of a fire.
On the convertible specifically, the side head-thorax airbag may not deploy correctly in a side-impact crash, reducing protection for the occupant. There is also a rearview camera software issue where the image can disappear or degrade while reversing, leaving the driver without a full view behind the vehicle. Rounding out the list, a software fault in the audio module can prevent the audible seat belt reminder chime from sounding, meaning the driver may not be alerted that their belt is unfastened.
