 I bought my 2011 Sorento with 18k on it in 2013. It has been a great car for the past three years. This year it was at just over 90k. I have always done everything I am supposed to. Plus I am a slow accelerator, typically I cruise at 2000 RPM in the city and 2500 on the highway not passing 3000 during acceleration. Then last month I heard a god awful metal sheering sound and the car skidded to a halt. Had it towed to the mechanic and was told the cylinder tubes had corroded and the cylinder heads were shifting and scraping the sides and that the engine could no longer be started. Cost for a used engine with the same amount of miles is right around $4500. If I want a re-manufactured one it is even more. Warranty is not an option because it cancels at 5/60 on used purchases. What is worse to me is a I still owe $14k. I did some research and it looks like this is a common problem in 2011 and 2012 Sorentos. I had planned on buying a Kia again in the future but I think I will stick to brands I have had good experiences with. I don't know if I will repair it at some point or turn it into a $14k paper weight. I would steer clear!
