engine light came on, having no problems with vehicle, all maintenance done. Took into the dealer in Albuquerque New Mexico while traveling through. Reported that the catalytic convertor was going out as well as the Hep lock Vac filter, which was not covered and some other parts (450.00 later). When I left the vehicle at the dealer it was getting 32 MPH, when I left the dealer after working on the vehicle it read 12mph, Dealer was notified and vehicle brought back in. Dealer wanted me to pay to remove the engine top and look inside. When asked about why this happened, twice for this vehicle. YES twice.. They did not know. Now also paid another 200.00 dollars to replace another filter and have the fuel injection cleaned as well. Now gets 33 MPH but hesitates when going 30. Dealer in Sioux falls thought the above filter would fix this. KIA never responded back to us to follow thru on why this vehicle needed 2 catalytic convertors at 27,000 miles and then again at 73,000 miles. And I am left with a car not running as well since the repairs were done. Car now hesitating. Vehicle was bought in 2008 new off the show room floor.
