All, I have read the posts about the 2017 Kia Niro jerking/shuttering problem. My Niro has been at the dealer for nearly 3 months. I was experiencing the same jerking/shuttering problem. They have narrowed it down to the EGR (exhaust gas recirculation) system. They have a new short block, head and EGR valve. Now they are waiting on an EGR 'tube'? I'm hesitant to take this car back. They can't yet tell me if the corrections they have made will fix the problem. Has anyone else had these fixes and did they work?
