The reservoir on my 2003 kia Sorento ruptured and all the coolant leaked out while I was driving. I pulled off the highway and into a gas station and the let the car cool. I then added in anti- freeze and filled it with water and drove another 10 miles and dropped the car at a repair shop. The next day the car would not start. The kia dealership is saying it is not covered under warranty.
