The Sonata is not free of rattling noises; I replaced its engine with a rebuilt one, and there is a six-month engine warranty. The motor is not free of rattling noises. For your information, I swear to God the engine cost around 6 thousand. Also, the oil pump is the known defective manufacturer issue with Sonata oil pumps. Motor mileage is 228800. And I request between brackets the tape: I don't see them between brackets (any Yemeni from Al-Shifa dealers made a tape on my head, you can plug it with you). God bless everyone..
