2014 Hyundai Sonata 2.4 Dealer oil change on 8/3 (dealer where i purchased vehicle) Today, after 15 min of driving, i hear a weird rattle from under the car. I get under as far as i can and it sounds like it's coming from the filter area (covered in plastic with a narrow access hole so not 100% sure). I pull into the Hyundai dealership near my office (different dealership) and they take a look. Sure enough, the filter is the issue. After the tech removed the oem filter and changed the oil, the noise vanished. He showed me the filter and it had a small dent on the bottom (where bypass valve relief spring sits). They used QSGB since they are one of the Quaker State preferred dealerships and changed the filter (he showed me the one he was installing). This dealership's concern (and mine) is that the dent 'may' have been there during the initial installation because it is almost impossible to get a dent like that where the filter sits, but it is 'possible'. Anyway, check those filters if you have someone else change the oil. Just in case.
