Hyundai Sonata problems, by model year and system
2,997 complaints owners filed with NHTSA about the Hyundai Sonata 2016–2027, and the 6 systems the record is deep on — engine (1,524), electrical (462), fuel system (319), transmission and drivetrain (306), steering (215). Each system has a page across the years; 13 model-year pages go deeper still. Every figure is a linked federal record; none is a failure rate or a verdict on one car.

Complaints owners filed with NHTSA naming each system, per model year; a bold count links the year’s own page on that system. Counts scale with sales and with time on the road; nothing here is a rate, and NHTSA’s headings are coarse (“Power Train” is the transmission and the driveline).
Common questions
Source: NHTSA complaint databaseWhich Hyundai Sonata system draws the most complaints?
Engine: 1,524 complaints across 12 model years, 51% of everything owners filed about the Hyundai Sonata. A count, not a rate — it says nothing about how many were sold.
Which Hyundai Sonata year has the most complaints?
2016 (883), 2017 (876), 2018 (382). Older years have had longer to collect them; the year pages show each year's share by system.
