2004 Kia Sorento Owner Comments

problem #1

Sep 252006

Sorento 4WD 6-cyl

  • Manual transmission
  • 45,814 miles


I had back firing and the possibility of stalling. Of course I did report this to lawleys, but their response was, well we can't find the problem, so when the check engine light comes on, then bring it back. I had traveled to el paso, tx. And when I was ready to come home, I started this vehicle and it had a very loud clicking noise. I had no oil in the car and there was no warning. As far as the verification of oil changes, I had some, but I didn't have a recent one because it was not time to change the oil until I got back home, but they did not care. Well, the second time that I had a problem I was in willcox, AZ. It's about 50 miles outside of Sierra vista. When I got out there the check engine light came on, and if you read your manual, then you know not to drive the Kia with the check engine light on. They said to drive it home. This was on a Saturday. I had to wait until Monday to bring it into the shop. Come to find out, there was a very big problem with the engine. The lack of power, the backfiring of the engine, it all came from a cylinder misfire. There were dents in the piston top, cylinder wall was damaged, and valve damage, to include metal shavings in the cylinder. It is stated in my report that there were concerns about this problem being in the intake manifold with other vehicles. This caused the damaged areas that I recently mentioned. This of course caused problems with the performance of the engine. If you are having the same problems with your Kia and your dealership tells you they can?T find the problem, then mention the concerns about the intake manifold. Every dealership knows that these vehicles are badly made and they will find any reason to not have to pay to fix your vehicle. Make sure you have your receipts or they will not be willing to help you at all. After my dealership diagnosed it, they said that because I was missing an oil change, I would have to pay $350 (for the fluids needed) and that they would replace the engine.
