During all of the 5 incidents in 2009 the engine misfired violently. At times 35mph was max speed. Cronin Kia had my vehicle over 30 days in 5 visits in 2009. They have replaced; two cat. Converters, the ignition coil pack and spark plugs, a leaking fuel injector and associated wiring. Please note the error codes for visits 1 and 5 (3/17/09 and 7/14/09); P0300-P0303-P0305-P0273. Visit number1 also had codes; P0420-P0430 and P0170. The duplicate codes indicate the problem affects "bank 1 only. Code P0170 spells out the problem; "fuel trim malfunction-bank 1".the destroyed catalytic converters were the result of the fuel trim problem. The same for the leaking fuel injector. I believe it is only a matter of time before the other bank 1 injectors fail. The fuel trim must be a function of the vehicle's computer. I believe the "bank 1 fuel trim malfunction" and/or the electronic stabilization program (esp) and/or the vehicle's computer are the source of this dangerous problem. There is a recall on the esp; SC-044 - March, 2005. "the esp system may cause the engine to reduce power and may cause a braking action at one of the wheels". "brake application caused by inadvertent esp activation may result in loss of control and a crash".the front brake pads on my vehicle were worn out at 41,000 miles. I asked Kia customer service in an initial letter if this was premature. Of course, I received no answer. After the number 5 incident(July, 2009) the engine would stall even after a leaking fuel injector and associated wiring were replaced. It stalled less than a mile from cronin and three times the next day. During the number 5 incident the esp shut itself off; "esp off" appeared in the instrument panel. I passed this information to jeff wyler Kia service department. This was ignored. The final (number 6) attempt to repair the problem consisted of a joy ride after which they declared; "all operations are normal" they consider this problem amusing. They refused to contact Kia!

: the contact stated the check engine light illuminated. The dealership inspected the vehicle a total of eight times. Each time the engine light has been reset however, the light illuminated again. The dealership has been unable to determine why the engine light continues to illuminate.
