Engine connectors c144 (throttle position sensor), c129 (mass air flow sensor) and c146 (idle speed actuator) lose circuit continuity with movement of the engine causing engine hesitation, loss of power and false "check engine light " indication on the instrument panel. Wiggling the appropriate connector restores continuity temporarily but it will recur again shortly within a day or two of operating the vehicle.

Continuation of complaint.... I then checked the federal safety agency website for recalls or service campaigns and found 3 recalls that fit in my VIN range. I immediately called kia's 800 number and asked if my vehicle was included and was promptly told no. I believed this response since it was coming directly from the manufacturer and not the dealer. About 2 months later, I received a disturbing call from a representative from kia consumer affairs telling me to immediately stop driving the vehicle because the same 3 recalls I saw on the federal safety agency website and called to inquire about included my vehicle. The recalls were: brake line recall-the steering intermediate shaft coupling can contact a hydraulic brake pipe causing fluid leakage. This condition can cause a loss of rear brake increasing the risk of a crash. Electrical wiring- the wires connected to the c123 and c124 connectors can be put under tension by movement of the engine, thus pulling the wires and connectors, loosening them and resulting in a loss of circuit continuity. This condition can cause engine stalling, increasing the risk of a crash. The third recall was an obd label. I could not believe that kia put my family and me in so much danger by telling me that my vehicle was not involved. The kia representative told me that kia would provide me with a loaner vehicle. Since I knew that I could possible die by continuing to drive this vehicle, I took a day off of work and took the vehicle back to the dlr. By this time, I had kept a timetable and log of everything that had gone wrong with the vehicle and presented it to the dealer. The list included, of course, the check engine light on, hesitation on acceleration, vehicle shakes severely when the wheel is turned, the idle surges when the vehicle is stopped, the rear window defogger had come off of the vehicle, the radio had started to static and turn on loud even when it was turned off, the volume knobs on the radio worked intermittently, the windows rolled up and down
