So ive never had any problems with my kia ceed untill i took it to my local indy garage,It went in for its service oil change fuel filter air filter,I was told it looks like the fuel filter has never been changed not good for a 7 year old car. It was running fine after the service but the second day i pulled out of my driveway and a couple of yards down the road the engine jerked and then cut out, engine light came on,Took a few more turns than normal to start it. But after that the car was running fine. The fault code was insufficient fuel supply. But a couple of days later i started to get loss of power it wasn't pulling like it would normally but the problem is on and off some days its fine other days i get lack of power,If i turn the car off and restart then i get full power back,But then it returns a couple of days later. The garage have replaced their fuel filter but its happened after that so it cant be the fuel filter but they have no idea whats wrong as no other fault codes have been logged in just that once when the engine light came on. It has jerked and stalled for a second time but no engine light came on this time when this happens it takes longer to start up again. The garage had my car for three days taking it out three times a day but the problem never happened with them.
