 I bought my Kia used. So of course the 100,000 mile warranty was not valid. I have poured so much money into this vehicle over the 3 years I've owned it. I maintain it properly, oil changes, new tires, etc. Well, I just found out the entire rear axle and differential completely rusted/rotted away to nothing. The only thing holding up the car was a shock! I truly believe this car was made poorly with cheap metal. Kia will not help me or stand behind the cars they build. When replacing the rear axle the mechanic found a part that was manufactured wrong in the factory and put on backwards. Again, KIA stands behind nothing! I could have purchased a rental car with all of the times I've had one.
