Every Sonata model year from 2004 to 2025, scored on reported failures weighted against how many were sold — and ranked against every other Mid-Size Passenger Car of the same year.
Across 22 scored model years the Sonata needs fixing less often than its class, and repairs cost about what you would expect. The spread between years is what matters: 2010 is its strongest, 2011 its weakest.
Longer bar is better. Rank is against every Mid-Size Passenger Car sold that same model year.

The line has moved around across 22 model years, with its weakest stretch in 2011–2023. The recent trend is upward. This 2025 car falls in a middling stretch.
All 12 systems, measured against the class average for each model year.
Every Sonata model year is scored across 12 separate systems — engine, transmission, brakes, electrical, steering and suspension, structure, interior, and five more. Each system is compared against how often that same system fails on the average Mid-Size Passenger Car of the same year, so a common failure is judged against how common it is everywhere else.
Across the last three model years (2023–2025), the trouble concentrates in one place: engine. That system draws issue reports more often than the same system on the average Mid-Size Passenger Car of its year — which changes what you should be inspecting before you buy.
All 18 Mid-Size Passenger Cars from 2025, plotted by how often they need fixes and what those fixes cost.
2010 is the strongest Sonata model year on record, ranking #15 of 46 Mid-Size Passenger Cars that year.
2011 is the weakest year in the model's history, ranking #48 of 48.
The 2025 Sonata ranks #6 of 18 Mid-Size Passenger Cars — the upper half of its class.
Failure reports filed with NHTSA — submitted by vehicle owners and repair shops alike — weighted against US sales volumes so a high-volume model is not penalised for selling well, then benchmarked within segment and model year.
