 I bought this as an upgrade to my 2011 Sportage LX. The LX's 2.4L engine wasn't quite up to the task of pulling my 1,155lb camper. It would struggle up hills while the A/C was running. I figured I would get the 260hp turbo one, and alleviate that issue. Well, I was VERY wrong.@3,00 miles - detonation sounds in engine.Dealer told me it was normal@5,500 miles - Total spark plug destruction while towing 1,700lb trailer@6,500 miles - Again, spark plug failure, and hole in cylinder #3 while towing 1,155lb trailer.Kia blames overloading, yet the car has a 2,000lb towing capacity.Had to file lawsuit, which is currently pending Kia's response.
