NHTSA has not crash-tested the 2021 BMW M340i, so it carries no Safety Index and no star ratings from the agency. Without that data, MotorCaliber cannot assign a crash-safety standing. What the record does show is a Light recall and complaint burden band, six recall campaigns spanning seat belts and back-over prevention, and ten unverified owner complaints with no reported crashes, fires, injuries, or deaths in the NHTSA complaint file.

ANALYSISHow safe is the 2021 BMW M340i?
The 2021 M340i's Light burden band reflects a recall and complaint volume that sits toward the lower end of what MotorCaliber tracks across the broader vehicle population. The six recalls are notable in that four of them involve seat belts, a restraint system that is directly relevant to occupant protection in a crash. The seat belt buckle assembly campaign, which was specific to 2021 330i, M340i, M3, and 330e xDrive vehicles, is the most model-year-targeted of the group. The back-over prevention camera recall adds a driver-assistance safety dimension. The ten unverified complaints show no reported crashes, fires, injuries, or deaths, and the engine-heavy complaint pattern does not intersect with the recall topics. No NHTSA-tested sibling years exist in the data provided, so there is no crash-test comparison point available for this nameplate.
NHTSA // RECALLSDoes the 2021 BMW M340i have any recalls?
The six recall campaigns for the 2021 M340i target two distinct safety systems. Four campaigns address seat belts, including a front buckle assembly bolt that may not secure properly and broader seat belt concerns shared with other 2021 BMW models. One campaign covers seats. One covers the back-over prevention sensing camera system. NHTSA issued no park-outside or do-not-drive directive in the campaign summaries provided, but shoppers should verify remedy status by VIN at nhtsa.gov.
