2025 Kia Niro Safety Rating

NHTSA gives the 2025 Kia Niro 4 out of 5 stars overall, below the 5-star median for the 13 comparable 2025 vehicles NHTSA rated in this class. That places it at the bottom of its tested class. Four stars overall is a solid result, though the sub-scores are where the meaningful differences sit.

NHTSA published results for every NCAP test in this program, so the overall star rating rests on a complete set of crash and rollover results.

NHTSA's dynamic test put this vehicle's rollover probability at 11.8% in a single-vehicle crash — the figure behind the rollover star rating, published here because the star alone hides how wide each band is.

Across the 3 model years we hold for the Kia Niro, the figure ranges from 4-star (2025) to 5-star (2023), so the 2025 car is best read against its own model history rather than in isolation.
