My son changing the oil on his 2013 Sonata. Took it over from his sister who bought it before I was familiar with the Theta engine. Through some incredible persistence of my wife she worked with a local dealership to have the recall work done free of charge which resulted in I believe basically a new bottom end.
Car has 163k now and while the consumption is greatly improved I still keep it on a tighter 3-4k OCI schedule. Along with my daughter’s new Civic, these are the only two DI engines in the family.
