DATANot crash-tested
The 2021 Hyundai Nexo presents an unusual profile: it has not been crash-tested by NHTSA, leaving its occupant protection unrated by federal star safety scores. Nevertheless, its record shows a significant recall and complaint burden. Two active recall campaigns have been issued, both of which instruct owners to park their vehicles outdoors due to issues with the hydrogen fuel system. This is a severe directive that demands immediate attention. Further, a small but notable number of owner complaints are on file. The absence of crash-test data means no federal safety index can be computed, and it also means that, while the hydrogen system concerns are clear, the vehicle's crashworthiness remains an open question for consumers.
The 2021 Hyundai Nexo was not crash-tested by NHTSA, carries a Heavy recall and complaint burden band, and has two recall campaigns on record per NHTSA data at nhtsa.gov.

ANALYSISHow safe is the 2021 Hyundai Nexo?
Hydrogen fuel system integrity defines the 2021 Hyundai Nexo's safety profile, a fact underscored by its recall record. Both of the vehicle's two recalls address this critical area, one focusing on pressure relief devices and the other on leak-detection sensors. Notably, both recalls carry "park outside" directives, the most urgent consumer action language issued by NHTSA. For a fuel-cell vehicle, such issues are structurally significant. This is true despite the low total recall count. The vehicle's two owner complaints, though few, also touch on the Electrical System and, importantly, the fuel system, echoing the concerns highlighted by the recalls. Without crash-test data for sibling years, a comparative safety reference point for the model is unavailable.
NHTSA // RECALLSDoes the 2021 Hyundai Nexo have any recalls?
Both recalls for the 2021 Nexo target the hydrogen fuel system and both carry park-outside directives. The first, covering 2019 through 2024 Nexo vehicles, involves a thermally activated pressure relief device that may break or crack, posing a hydrogen release risk. The second, covering 2019 through 2021 Nexo vehicles, involves hydrogen gas detection sensors that may fail to detect leaks. Owners should treat both campaigns as urgent given the park-outside designation.
