The 2021 Hyundai Sonata N achieves a NHTSA Safety Index of 90 out of 100, placing it in our "Exceptional" band, a rating underpinned by perfect sub-scores in crash protection and avoidance technology.

ANALYSISHow safe is the 2021 Hyundai Sonata N?

The 2021 model year is the debut year for the Sonata N variant in the NHTSA dataset, so no prior-year Safety Index exists for a direct comparison. What defines this specific year is a split story inside the Index itself: crash protection and avoidance technology both score at their respective ceilings, 70/70 and 10/10, reflecting the perfect side and rollover stars plus a full suite of standard crash-avoidance technology including forward collision warning, lane departure warning, and electronic stability control. The drag on the 90/100 total comes entirely from the defect record sub-score of 10/20, a direct consequence of four active recall campaigns touching the fuel system, powertrain, and windshield. The fuel delivery recall is specific to the 2.5L turbocharged engine fitted to this N variant, making it particularly relevant here rather than a fleet-wide carryover concern. The 118 reported complaints, with Engine and Power Train among the top categories, align thematically with those recall components, though they remain unverified allegations. The Exceptional band rating is real and data-supported, but the defect-record penalty is equally real.

NCAP // CRASH TESTHow did the 2021 Hyundai Sonata N perform in crash tests?

The 2021 Hyundai Sonata N achieved a perfect 5 out of 5 stars in NHTSA's side impact and rollover protection tests. Its rollover risk was assessed at a low 10 percent, and the dynamic tip test indicated no tip. It should be noted that overall and frontal crash ratings were not published for this specific variant; this indicates an incomplete assessment by NHTSA, not a poor performance in those categories.

USED BUYERWhat should used buyers know about the 2021 Hyundai Sonata N?

Owners of the 2021 Sonata N should verify that all four of its open recall campaigns have been addressed.

  • NHTSA awarded this variant perfect 5/5 scores in side and rollover crash protection, with a 10 percent rollover risk and a passing dynamic tip test, but overall and frontal crash ratings were not conducted for this specific body configuration.
  • The defect-record sub-score of 10/20 is the sole reason the Safety Index sits at 90 rather than higher, making recall remedy status the single most important safety variable for a used buyer of this exact year.
  • All 118 owner complaints on file with NHTSA are unverified allegations, with Engine, Power Train, and Fuel/Propulsion System accounting for the majority of reports, categories that overlap directly with the active recall subjects for this model year.
