DATANot crash-tested
The 2021 BMW M4 does not carry a federal Safety Index score or star ratings, as NHTSA has not subjected this model year to crash testing. This leaves its structural and occupant protection performance unrated. The federal record shows a limited recall and complaint burden: two recall campaigns have been issued, and one unverified owner complaint is on file. This overview is incomplete due to the absence of crash-test data.
The 2021 BMW M4 was not crash-tested by NHTSA and carries two recall campaigns plus a Light recall and complaint burden band, according to federal data published by NHTSA.

ANALYSISHow safe is the 2021 BMW M4?
The 2021 BMW M4 receives a Light burden band rating, indicating its combined recall and complaint volume is low relative to the broader vehicle population. Federal data show two recall campaigns. One addresses seat-belt hardware across several 2021 BMW models. The other concerns hydraulic brake components shared with certain 2020 to 2021 8 Series vehicles. The single reported owner complaint also points to the service brakes, creating a narrow but notable thematic overlap between the recall record and the unverified owner report for this year. The absence of NHTSA crash-test data for the 2021 M4, and the lack of tested sibling years in this guide, means the Light band is the sole federal safety signal available. Shoppers should treat this as a partial picture, not a comprehensive safety assessment.
NHTSA // RECALLSDoes the 2021 BMW M4 have any recalls?
