Complaints filed with NHTSA name the vehicle system involved. For the 2016 Hyundai Sonata, engine & cooling issues stand far above everything else.
"I am concerned that the engine may seize or stall without warning while driving, creating a risk of crash, injury, or death. The Theta II engine defect is known to cause engine seizure, stalling, and fire. Hyundai has denied warranty coverage based on mileage and second-owner status — both of which are explicitly prohibited as denial grounds under the Settlement — leaving me driving an unsafe vehicle."
"Cylinder 3 misfire code and rough idle/driving car tries to stall out, engine is consuming a quart of oil every 500 miles and has 30psi compression in cylinder 3. Car only has 129k miles"

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.
As of October 26, 2026, owners have filed 726 complaints about the 2016 Hyundai Sonata with NHTSA. The most-reported system is engine & cooling.
The 2016 Hyundai Sonata has 6 NHTSA recalls on file. Recall repairs are free at any dealer.
NHTSA gives the 2016 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 October 26, 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.
