Went to service my truck with 2,000 miles on it for a check engine light. The vehicle is still under warranty. The problem was that an EGR valve needs replacing. Should take half a day to replace once part came in. So, it should be roughly 13 hours to get done. The dealership had the vehicle for 30 hours to replace one valve. Take your vehicle somewhere else if you want warranty work done in a timely manner.
