I heard a ticking while travelling to MA on 684 north of CT when the noise got louder. I stopped and had to tow the car home. When I when on in the hundai Sonata forum there were a lot of folks talking about the problem. They mentioned talking to the dealers but no one heard of a recall on the engine. So I just like them had to fix the engine by the way which is the most expensive 4 cylinder engine out there. I also called the manufacture about it and they told me that there's no recall yet and I have to fix it myself. Well I went to got the bearing and craft and a oil pump. This is when I learned that they heve redesigned a oil pump that car 06 07 08 09 mdels. I asked the guy why would they do that, cause it means you have to buy a new oil pan and bolts, he said there is a deffect in the original oil pump. So I said it's costly for us so why they dont do a recall? he said no one is complaining and it's very costly for the company. So I ask can someone look into it . Really why would they redesign a oil pump for a car as old as just five yrs old.
