I purchased a 2003 Kia Sedonna with 15000 miles on it 6 weeks ago. Since that time, the "check engine" (emission control systems) light has come on three times. The 1st time the dealer indicated that this was caused by failure to tightly close the gas cap after fueling. The second time, after I assured the dealer that I had been diligent in making certain that the gas cap was tightly closed after each fuel stop, they replaced an emmission control valve and put on a new gas cap. Less than two weeks later, the light has once again come on.
All three times the light has come on I have been traveling in slow traffic, usually at speeds of less than 30 mph. The car has been in Drive with the Overdrive turned off.
Has anyone else experienced this problem? Any insight or advice? Other than this I absolutely love my Sedonna, but am beginning to worry that I have purchased a "Lemon"! Any suggestions?
