I purchased this vehicle Dec. 2017 with 318 miles. Vehicle began to sputter when trying to start. First time, towed in was told nothing was wrong. Went home, next morning the vehicle sputtered to start. After 3rd try & loud sounding, I popped the hood & the entire engine was shaking in its cradle. Towed in again, dealership diagnosed coils misfire & replaced. Vehicle duplicated the same problem a week later. I replaced the battery. Vehicle would not start again the next day. Third time, dealership diagnosed fuel pump but ended up replacing the entire fuel injection system because replacing the fuel pump did not fix the matter. They had my vehicle for 2 full weeks. Had the vehicle back 2 days, vehicle would not start but continued to sputter. Dealership has now had my vehicle 5 weeks, first said they couldn't get it to duplicate the problem but kept my vehicle anyway. Then said coils were bad even though they just replaced them 3 months ago something is causing the coils to misfire. I have no answers. Even with kia consumer affairs involved, no one has an answer. At one point kia consumer affairs called to ask me how the vehicle was running because the dealership told them they did not even have my vehicle anymore. I thought I was going to have to make a report to my insurance carrier. My vehicle has 30,000. I've maintained regular oil changes & other required maintenance as suggested, faithfully.
