Consumer Description

At 79,000, the engine started running very rough. I took it to the dealer. It’s got a cylinder that won’t fire. I have an extended warranty( big $!) but I’m getting the runaround from Kia. It’s been almost 3 weeks. They’re dragging their feet because they know these Theta II engines are JUNK! I’ve maintained my own vehicles my entire adult life, and I don’t drive crazy either. It also had a knock sensor recall, which most likely kept this issue from being a recall
