Jim Click Hyundai Automall

Not sure if it's a reflection of the dealerships service abilities (incompetence) or the Hyundai vehicles quality, or both. Tried to schedule a service for a code that came up during emissions. My local mechanic diagnostic indicated a Technical Service Bulletin for the electronic computer module requires a reset/update by the dealer before vehicle can be properly diagnosed. Earliest availability is 3 months out. Either service at this location is poor and slow and/or Hyundai vehicles are trash. Service tech indicated they have a lot full of vehicles waiting service and could not get me in any earlier. The vehicle is a 2012 Elentra purchased used for reference. Car drives fine but cannot get emissions/tags prior to expiring until vehicle is services in 3 months. I will be out of a vehicle and service dept is of no help.
