Reliability and safety are the two dimensions that matter most for long-term ownership costs.

With 7.0/10 for performance, this is a car tuned for daily driving rather than excitement — perfectly capable on the commute, unremarkable on a back road. At 7.7/10 for technology, the infotainment and driver-assist package does its job without setting benchmarks — check which features cost extra on lower trims.

At 7.8/10 for value, it delivers fair pricing for what's on offer, though the best alternatives in this price range score slightly higher. At 5 years old, it's worth checking whether a newer generation or refresh has addressed any weaker dimensions — compare it to the current model year before buying.
Verdict: Nothing about the 2021 Hyundai Sonata SL will scare a sensible buyer off. It scores consistently across the board, and it does what a good sedan should — quietly and competently.
