DATANot crash-tested
The 2021 Mercedes-Benz CLS-Class presents an anomaly in federal safety data, with no NHTSA crash-test ratings on file and, consequently, no computed Safety Index. This absence of critical performance metrics means the vehicle carries neither an endorsement nor a red flag from the federal crash-testing program; its crashworthiness remains unassessed by that agency. The record does, however, show a Clean burden band, with zero recalls issued for this model year. A single owner complaint was reported to NHTSA, a notably low figure.
The 2021 Mercedes-Benz CLS-Class was not crash-tested by NHTSA, carries zero recalls on file, and falls in the Clean recall and complaint burden band according to NHTSA federal safety data.
