2020 Hyundai Sonata problems
What owners reported to NHTSA, at what mileage, and every safety recall for this model year.

- No denominator: popular cars get more complaints. Counts are not failure rates; a best-seller will show more reports than a rare model.
Most reported problems
Complaints by component. One complaint can name more than one component, so these add up to more than 181.
When problems show up
Reports by odometer reading at the time of the problem, top components. Each bar is a 25,000-mile band, labeled by where it starts (0 = 0–25k miles). Reports without mileage are left out.
