Review on 🔒 31010-3L600, 310103L600 Gas Cap Replacement – Compatible with Hyundai Accent, Azera, Elantra, Elantra GT, Entourage, Equus, Genesis, Genesis Coupe, Santa Fe, Sonata, Tucson, Veloster, and More – Improve Fuel Cap Performance by Matt Travers

Should pay more attention to other reviews. Whilst this item appears to fit, the one I received does not make the required 'click' even though it is stamped on the item. I took the car to the mechanic and they checked where the gas cap would be and they said there was no problem so the problem is in the cap itself.
