Hyundai Sonata (2011–2019): what actually fails

The documented failure patterns on used Hyundai Sonatas — the mileage window where each shows up, and what the repair typically costs at an independent shop. This is the same data NoLemon's Brief checks against every VIN.

2011–2019 TYPICAL 60k–160k MI $3,000–$5,500

Theta II engine failure / seizure

Theta II engines suffer rod-bearing failure; huge recalls and an extended warranty exist. Verify the knock-sensor software update and any engine replacement records — a replaced engine is a plus.

BEFORE YOU BUY
Ask for repair records covering this item. If it hasn't been addressed and the car is in or near the mileage window, price the $3,000–$5,500 repair into your offer — or make it the seller's problem.
