“I bought Genesis at march 24.2015, and I am not owner right now because I sold that car. When I bought car, there were noise at engine at new car. After cheking the car, Hyundai engineer said short block problem . It is exactly same problem of sonata (theta 2 engine). I think Genesis engine(rhamda 3.8) also have problem. I will attach related paper. Thank you.”
