I have a 2006 KIA Sportage 2.7 v6 4x4. I like the car but lately it has not been good. I only have 19000 mile on it and keep it in a garage. At 18000 miles the engine started to miss and the check engine light came on. I took it to the KIA dealer and after 5 visits and changing parts that did not fix it and paying for them, they finally fixed it by changing the plugs and the ignition wires. I was charged 5 times the price I would have paid at Auto Barn or Pep Boys. For what KIA charges for the plugs and wires they should last a lot, lot longer then 18000 miles and they should have changed them first. These parts should have been changed under the warranty.
