Last week, during an oil change, I was told that my transmission cooler hose was leaking and needed two new ones. In addition to that I would have to pay for the cooling service which would be a total of about $200. No telling how long the car was without coolant, but my car has never over heated. Coincidentally, I received an email that there is a recall on the kia/2011 for the same issue! I was told that there was nothing kia would over if it was not included in the recall which it most likely should be by looking at online reviews. Please investigate.
