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 HYUNDAI SONATA HYBRID, the leading complaint category is engine (331 filings), followed by electrical system and unknown or other. For the KIA NIRO EV, it is unknown or other (28), ahead of electrical system and power train. 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 HYUNDAI SONATA HYBRID an average 5/5 crash-test rating versus 0/5 for the KIA NIRO EV, 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.
