I've been searching for information on the transferability of the 10 year/100K mile powertrain warranty of Kias and keep finding conflicting information. I am looking at a 2007 Sorento being sold by a Kia dealer that is NOT currently certified. I told them that I'm interested but only if they will certify it because I was under the impression that the only way I would get the balance of the warranty was if it was sold as such. They told me that this was the case and that they would be willing to work with me on the price. Forgive me, but I regard car dealers as a necessary evil and don't trust them very much. Can someone confirm that if a certified pre-owned Kia is bought from a Kia dealer that the balance of the factory warranty transfers? If so, what do I need to do to make sure that this happens? Do I need something in writing? Do I need something directly from Kia stating that this is the case, etc...?
