I was driving on a back road to my next destination when suddenly my steering wheel became stiff. The eps and esc lights were on in the dashboard. I was able to pull the car over. Turned it off and back on. Seemed ok. Power steering returned. Eps and esc lights off. Went up a few feet to stoplight. Lost power again. Did not feel safe. Stopped the car. Called for tow truck. Towed to nearest Hyundai dealer. They did diagnostic tests. One tech said it was steering column assembly. They said to follow up with regular dealer next week if it happened again. On 4/7/15 car brought into dealer again for same problem. They did an eps update. On April 15, 2015 my husband was driving us. He almost lost control of the car on the highway because he lost power steering. He pulled over restarted car twice. Then steering came back. Eps and esc lights went off. Called Hyundai dealer today. He said to bring it in. I had it towed in.
