Hyundai and Kia are going to have class-action law suit(s) soon if their dealers are insisting owners must use OEM oil filter to have engine warrantied.
"Owners who bring their Kia vehicles to the dealer with complaints about engine noise should be aware that one step the technician must follow, per TSB ENG 114, is to check to see if an aftermarket oil filter is installed. If a nonapproved filter is in place, the technician will perform an oil and filter change and bill the customer, regardless of how recently the oil was changed by the owner."
Is there a list of "Hyundai(or KIA) Approved Oil Filters" ? Or the list has only Hyundai(or KIA) OEM filter on it ?
