Kia K5
NHTSA safety across every Kia K5 model year we cover.
Across the 6 model years of the Kia K5 we cover (2021 to 2026), the strongest crash-test showing is the 2026 at 90 on the NHTSA Safety Index, and the lowest is the 2023 at 76. 20 recalls have been issued across those years.
The Kia K5 is a front-wheel-drive midsize sedan aimed at value-conscious buyers who want a stylish, well-equipped alternative to the Honda Accord or Toyota Camry. Replacing the Optima nameplate for 2021, the K5 targets younger commuters and families seeking modern design and competitive pricing in a crowded but important segment.
The Kia K5 carries a mixed but ultimately serviceable safety record across the 2021 to 2025 model years covered here. At its best, the 2025 model earns an NHTSA Safety Index of 86 out of 100, a score that lands in the 'Strong' performance band and represents meaningful progress over earlier years that fell into the 'Average' band. Crash-test geometry tells a nuanced story: the K5 earns a perfect 5 out of 5 stars in the side-impact test, which reflects solid structural engineering on the flanks. The frontal and rollover ratings, however, both sit at 4 out of 5 stars, pulling the overall picture slightly short of class-leading status. The recall count of 19 across five model years is a number shoppers cannot ignore. That averages to nearly four recalls per year, which is elevated for this segment and suggests Kia has had to address a range of engineering and manufacturing concerns since the K5 launched. Owner complaints total 434, with 32 alleged crashes, 5 alleged fires, 49 reported injuries, and 3 reported deaths among the unverified allegations on file with NHTSA. These are allegations only and have not been proven, but the volume warrants attention. The honest bottom line: the K5 has improved its safety index meaningfully by 2025, and its side-impact protection is genuinely strong. However, the recall frequency and complaint volume give pause, and shoppers should verify whether any open recalls affect a specific vehicle before purchase.
WHAT REVIEWERS SAYReviewers generally praise the K5 for its sharp styling, composed ride, and strong value proposition within the midsize sedan segment. Most consider it a credible challenger to more established rivals, citing its feature content and driving dynamics as highlights. Safety technology availability tends to receive positive mention, though some reviewers note that the K5 trails top-tier competitors in overall refinement.
- The 2025 K5 reaches an NHTSA Safety Index of 86 out of 100, placing it in the 'Strong' band, but earlier model years in this generation scored in the 'Average' band, so year selection matters when shopping used.
- With 19 recalls across the 2021 to 2025 model years, the K5 has an above-average recall frequency for its segment. Always run a VIN check through NHTSA's recall database to confirm all outstanding recalls have been remedied before buying.
- Side-impact crash protection is a genuine strength, earning a perfect 5 out of 5 stars, but frontal and rollover protection both come in at 4 out of 5, meaning the K5 is not uniformly top-rated across all crash modes.
- The 434 owner complaints on file with NHTSA include unverified allegations of 32 crashes, 5 fires, 49 injuries, and 3 deaths. These figures are unconfirmed allegations, not proven incidents, but the volume is worth monitoring through NHTSA's complaints portal as you evaluate a specific model year.
