About the 2018 Hyundai Sonata Base

Our scoring places the 2018 Hyundai Sonata Base at 7.5/10 overall, which translates to a Recommended rating for this sedan. Its strongest dimension is Safety at 8.1/10, while Performance at 6.8/10 is where it trails the competition most noticeably. It's a solid all-rounder that delivers across most dimensions without obvious deal-breakers.

Reliability and safety are the two dimensions that matter most for long-term ownership costs. We score reliability at 7.8/10 — better than most direct rivals, if short of the segment's best. The safety score of 8.1/10 is solid mid-pack territory. If advanced driver aids matter to you, compare standard equipment carefully and verify ratings at nhtsa.gov.

Performance at 6.8/10 is a genuine liability and a score that should factor heavily into any buying decision. The powertrain and chassis dynamics trail class rivals by a meaningful margin — don't overlook it. Tech rates a reasonable 7.0/10: the essentials are covered and well executed, but rivals at the same price often include more as standard.

Priced from $23,575–$28,731, 26 MPG, seating 5, the Hyundai Sonata Base sits in the budget-friendly tier of the sedan market. The 7.7/10 value score says the pricing is fair rather than generous; cross-shop the segment before signing anything. At 8 years old, resale value, parts availability, and whether a successor model has improved on its weak points are all worth investigating before committing.

Our take: The 2018 Hyundai Sonata Base is a solid, well-rounded sedan that covers the essentials without obvious deal-breakers. The main caveat is performance — worth checking if those dimensions are priorities for you. For most buyers in this segment, it's a safe, dependable choice.
