2019 Lexus Rx450h Safety Ratings

The 2019 Lexus RX450h stands out in the MotorCaliber dataset for a specific combination: a clean zero-recall record paired with a five-star overall NHTSA crash rating and a full 10 out of 10 avoidance-tech score, the last reflecting standard equipment of both forward collision warning and lane departure warning across the lineup for this model year. Crash protection contributed 61 of a possible 70 points to the 86/100 Safety Index, a strong but not perfect sub-score that reflects the four-star frontal and four-star rollover results pulling slightly below the ceiling. No prior-year Safety Index is on file for comparison, so year-over-year movement cannot be measured here. The defect record sub-score of 14.5 out of 20 is the one area with room to improve, driven by 36 unverified owner complaints. Notably, Forward Collision Avoidance accounts for 11 of those alleged reports, an unusual concentration on a system that simultaneously earns full credit in the avoidance-tech scoring. That tension is worth watching: the technology is standard-equipped and scores well in the structured rating, yet a meaningful share of unverified consumer reports question its real-world behavior. Service Brakes at 9 alleged reports adds another layer of attention for prospective buyers.
