Complaints filed with NHTSA name the vehicle system involved. For the 2015 Hyundai Sonata, engine & cooling issues stand far above everything else.
"The engine failed due to the known recall defect, dealer confirmed loss of compression in cylinders 2 & 4. I am a federal employee stationed overseas on official duty orders, and Hyundai Motor America is delaying safety recall remedies and buyback negotiations since June 9th."
"I bought this car new in 2015, when I was at 97000 miles they had to replace the motor and turbo, I am now at 155844 and they are telling me that basically all 4 cylinders have low compression, cylinder 3 is the worst. They are telling me that this car has to have a new motor. I have not done anything to this vehicle to cause no compression. They want me to pay around 8800.00 to get this fixed."
For most vehicles, complaint volume spikes early and tapers off. The 2015 Hyundai Sonata peaked later than usual, in 2022.

NHTSA crash ratings measure how the car protects occupants in a crash — a separate question from the reliability complaints above. A vehicle can be both crashworthy and trouble-prone.

NHTSA gives the 2015 Hyundai Sonata an overall crash rating of 5 out of 5 stars. Crash ratings measure occupant protection in a collision; they do not measure reliability, which is what the complaint data above reflects.
All figures come from the U.S. National Highway Traffic Safety Administration (NHTSA) public APIs: the Office of Defects Investigation complaint database, the recalls database, and NCAP safety ratings, retrieved September 7, 2026.
Complaints are self-reported by consumers and are not verified by NHTSA or by this site. A single complaint may cite multiple vehicle systems, so system mentions can sum to more than the complaint total. Complaint volume is influenced by fleet size, media attention, and recall notices, and is not by itself a measure of defect rates.
