VERDICT

The 2021 Lexus RX 450h received a NHTSA Safety Index of 85/100, placing it in the Strong safety band. This standing is supported by its full crash-avoidance suite and an absence of recalls. However, this model year represents a two-point decrease from the 2020 RX 450h. Furthermore, a concentrated pattern of owner complaints regarding the vehicle's air bag system merits careful consideration.

The 2021 Lexus RX 450h received an overall 4-out-of-5-star NHTSA NCAP crash-test rating and a NHTSA Safety Index of 85 out of 100, derived entirely from NHTSA crash-test, recall, and complaint data.

ANALYSISHow safe is the 2021 Lexus RX 450h?

The 2021 Lexus RX 450h stands out for its complete absence of recalls. No service campaigns were opened against this model year, a meaningful distinction that separates it from years where even minor service actions can weigh on the defect record. This contributed to its overall NHTSA Safety Index score of 85 out of 100, placing it firmly in the Strong band, though this marks a two-point retreat from the 2020 model's 87. The decline traces to a defect-record sub-score of 14 out of 20, reflecting the index's weighting of complaint volume against sales exposure. Crash protection remains robust, with a sub-score of 61 out of 70. This is anchored by a 5-star rating for side impact and consistent 4-star marks in both frontal and rollover categories from NHTSA. The vehicle's avoidance technology sub-score achieves the full 10 out of 10, as forward collision warning, lane departure warning, and electronic stability control are standard equipment. A notable anomaly in the reported data is a cluster of 47 airbag-related complaints out of 69 total unverified owner reports; these unverified consumer allegations warrant attention despite not constituting established defects.
