2020 Hyundai Sonata: True Cost, Problems & Verdict
175 NHTSA owner complaints · 4 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. 2020 specifically: a year the record favours — 175 complaints, score 82/100. The caveats in the note apply to other years of this nameplate more than to this one.

Car was in reverse and all parking sensors were blaring when the car was found minutes later.
Blower motor malfunction at night. Smelled something burning. Extremely hot and humid outside. Windows fogged up inside which greatly reduced visibility. Checked the multifuse which controls the ABS, oil pump, cooling fan, & Blower. I discovered a burnt connection on one of the terminals for the blower. This is a huge safety and fire risk and needs to be addressed ASAP!!!! Upon my research, I’m finding several Hy…
The reverse camera only shows a black screen and will put drivers in danger while not being able to see behind them while reversing. This needs to be recalled and repaired. Especially in situations where a person is reversing out of a driveway onto a major/busy road. Sometimes it works, but a lot of the time it is just a black screen with the green, yellow, and red lines to indicate how far your wheel is turned. But …
