 In my earlier post I described the problem with the differential. The dealer replaced it with a unit from California. When they test drove it, it didn't sound right so they are now replacing that unit with a new unit from Washington. By the time they do that, they will have had the vehicle longer than I have. Anyone considering buying a new 2013 Sportage should get down and inspect the rear end for any signs of a fluid leak prior to purchasing it.
