My new Tucson with less than 400 miles is now displaying check engine lite, for the 2d time! I embarrassed the dealer into fix it first time because all the dealer prep was not done prior to delivery, Now the light is on again and I must wait 2 weeks for an appointment in Phoenix. Called another dealer and they want 3 weeks delay. My scanner code reports P2181,power train cooling system performance. It is 110+ F. In AZ now, isn't this ridiculous? Beautiful cars, can't get service in acceptable Time? Any ideas? Thanks
