ACURA RLX vs LEXUS IS 300

The ACURA RLX (2014–2018, 5 model years) carries 158 NHTSA consumer complaints and 5 safety recalls, while the LEXUS IS 300 (2001–2022, 13 model years) carries 156 complaints and 3 recalls. Severity indicators for the pair split as follows: 6 vs 32 crashes, 0 vs 7 fires, and 0 vs 0 reported fatalities.

Raw complaint counts favor whichever nameplate has fewer vehicles on the road, so the cleaner lens is components: which specific part families concentrate each model's filings? For the ACURA RLX, the leading complaint category is steering (53 filings), followed by suspension and electronic stability control (esc). For the LEXUS IS 300, it is unknown or other (18), ahead of vehicle speed control and tires. When the two vehicles cluster around the same component, the problem is likely a shared supplier or a shared federal standard under stress; when they diverge, each nameplate has its own defect signature independent of the other.

NHTSA's New Car Assessment Program gives the ACURA RLX an average 5/5 crash-test rating versus 5/5 for the LEXUS IS 300, aggregated across all model years with published scores. Use the side-by-side table below as your scorecard, but do not treat it as a verdict. Recall counts tell you how many defects the manufacturer has already been compelled to remedy; complaint counts tell you what owners are still flagging today; and safety ratings tell you how the vehicle performs in standardized barrier tests, three different lenses on the same underlying question.
