Reliability, what owners report, and what it costs to keep.
AVOIR's read: it scores well across the board with no single weak engine.
Owners have filed 69 complaints with NHTSA about the 2021 Lexus RX 450h, and it carries no recalls. These are owner allegations rather than confirmed defects, but the pattern of what people complain about is the most useful signal a used buyer has.

What stands behind each score for this car:
Owners have filed 69 complaints with NHTSA for this model-year, and air bags is the most reported area with 43 of them (62%). No recalls are on record for it.
AVOIR scores its reliability 96/100 (excellent) from NHTSA recall campaigns and complaint density. That figure is a raw complaint count, not yet adjusted for sales volume, so a high-volume model scores worse than it deserves.
AVOIR scores its longevity 90/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 2021 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
AVOIR's read: buy, because it scores well across the board with no single weak engine. Its overall ownership score is 80/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
