Consumer Description

Vehicle has been repaired due to broken valve. Vehicle was unsafe to drive. Valve burnt at 70 mph. Car threw misfire code P0303 and started shaking. This issue could have caused an accident. Valves were replaced at Young Hyundai in Ogden Utah. Valves were not covered under the lifetime rod bearing recall. Several people have had this failure on the Engjne issue group page. I have a photo of the valve. It is missing a chunk of the valve head. That piece was not located during the valve rebuild. The vehicle had 116,000 miles at time of failure and is consuming 1 quart of oil every 500 miles.
