My engine was replaced due to a recall for hesitation/lock up in November 2017. Not long after replacement the new engine begin to hesitate like the old engine. It has continued to do this, becoming worse. It is usually a double hesitation. In other words the car hesitates slightly, starts moving then hesitates again more seriously. The last time in December, 2018 the car did this I was making a turn. It was serious to the point that an oncoming car had to stop. This is exactly the same as the first engine. I'm very concerned about the safety of driving this car. The car has 34,000 miles but only 5,000 on the replaced engine.

I was driving the vehicle when the battery light came on and then the car started to overheat and then just cut off. I tried to start the vehicle but would not start. Had it towed to Kia wich told me it was the pulleys froze up and shredded the belt. Now Kia just replaced my engine from the recall. Now I always have the oil changed every 3,000 miles and I take it to the same place everytime now when they changed the engine they said I would need a new alternator but that was it. Not to mention I just had it at Kia for a oil change and a free inspection. Which the inspection stated nothing about the belts or pulleys which are supposed to be inspected. So that is twice they missed a worn out idler pulley. Now the mechanic I had looking at it told me it was so worn that it broke off and that there is no way they missed it.

I have been having repeated issues following the Kia theta II engine recall replacement (SC147) since June 2018. My car is practically new with 53K +/- miles, purchased new, and had all the recommended and required maintenance performed. I took my car to rick case Kia (dealer code:GA083) to have my engine replaced midsummer 2018. Since then I have been experiencing persistent check engine light (cel) issues for the same engine diagnostic code(P2191). Each time I take my car to the dealer for resolution, technicians give me different reasons for what they "think" could be the root issue. Thus far, I have been told the issue was due to bad gas, an O2 sensor gone bad, a leak, history code from another dealer not clearing the recall, and now a fuel kit will be replaced. It is my assumption that if Kia technicians truly knew what the issue was I would not have so many repeated trips for the same issue. To this date(December 14th 2018) they still have not provided a clear resolution. In light of recent events surrounding Kia vehicles, specifically Optima, catching on fire and engines randomly blowing up this is something that needs an immediate resolution.it impacts my safety as the vehicle owner and those driving around me. I have expressed how uncomfortable I am driving this car in the current state (with the engine light on) and my concerns are being dismissed. I am told that it is not a drivability issue and I can drive it away with the light on. It should be no surprise why that is not a comforting diagnosis as I have been back about 6-7 times now. I am currently making attempts to engage/escalate this with the Kia corporate office. In an attempt to be proactive I am seeking help!
