I have read similar reports of the same thing happening and under the recalls it lists this as a complication. I have called Kia and was told that my VIN number doesn't have a recall on it and was told that any repairs would be out of pocket. …”

When I contacted both our local dealer and Kia corporate, I was told that this particular VIN is not included in the recall, although the recall clearly states that it does meet the parameters. Upon further research, it appears that many others have experienced the same problems and been given the same information. …”
