I have a 2012 Sorento. We have had the engine just quit multiple times. We've had it to the dealer and a Kia tech rep from Kia National checked out the car. They can't diagnose or duplicate the problem. Im tired of not getting the problem fixed. There is something wrong with this car. I just contacted the National Highway Traffic Safety Administration and filed a complaint. There number is 888-327-4236. I know many other people are having the same issue. If you are having the same problem please give them a call and file a complaint. Thanks.
