2024 Hyundai Sonata: True Cost, Problems & Verdict
45 NHTSA owner complaints · 1 recalls · data-computed verdict. No opinions — public data only.
Editor's note
The sixth-generation Sonata (2011–2014) is the car that brought Hyundai's Theta II engine problem into the open. Connecting-rod bearing failure in the 2.0 and 2.4-litre engines leads to knocking, stalling and, in the worst cases, fire; Hyundai recalled 2011–2014 Sonatas in 2015 and 2017, extended the engine warranty, installed a knock-sensor detection system, and in 2020 paid a civil penalty to the federal regulator over the timing of the recalls. Read the full note on the model page. 2024 specifically: a year the record favours — 45 complaints, score 88/100. The caveats in the note apply to other years of this nameplate more than to this one.
