NHTSA Complaint #11529341 — 2014 HYUNDAI SONATA

The contact owns a 2014 Hyundai Sonata. The contact stated that while driving at various speeds, the check engine warning light illuminated with a burning odor and a knocking sound coming from the engine compartment before the vehicle stalled. The vehicle was later driven to the local dealer who discovered metal shavings inside the engine and engine oil and informed the contact that the engine needed to be replaced. The engine was replaced, and the vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 150,000. The mechanic stated in the engine evaluation notes rings in the engine bad, and the metal shavings would indicate the rings on the piston were not correctly installed or shimmed to tolerance, causing them to scrape the inner wall of the piston chamber. Further stating it is a mechanical issue and not the negligence of the owner.
