Car began hesitating and stalling, particularly from a stop. Engine light came on. Took the car to the KIA dealership for diagnosis. Was told by svc coordinator that the diagnosis indicated a bad knock sensor. The technician replaced the knock sensor, then test drove the car. It failed immediately. I was told that it would likely need engine replacement. After a few days, svc coordinator called and said that KIA recommended replacing the knock sensor (again) and perform a tuneup. They declined to replace the engine. The car runs in "limp home mode" (Kia's terminology), hesitates and stalls so as to make it very unsafe to operate. The engine on this car was replaced about two years ago for excessive oil consumption. There cannot be more than 30k miles on the new engine. KIA stated that there is a lifetime warranty on the replaced engines, but are apparently not going to honor the warranty. Car is serviced regularly and is in otherwise excellent condition.

This is how I am feeling and the reason for being an unhappy customer. I shouldn't have to keep buying gallons of oil to put in my car every other day. Oil change was done on Sept 6th along with spark plugs put in due to oil consumption. Took my car again to Kia on Sept 21th because there was no oil in my vehicle, so they put oil in. Then on Sunday Oct 2nd I had to spend $44 on a gallon of oil because there was no oil in it once again. It’s a recall and should be fixed regardless if it doesn't shut off while I'm driving, hearing the knocking noise, and or the check engine light comes on. First I was told to bring it or call if the check engine light comes on and stays on now I am told it has to come on and stay blinking. I can be on the highway with my family or infant grandchild and my car shuts off what if I cause and accident, kill someone, or myself or family dies in my car. Would you rather have a lawsuit or fix the problem before that happens. I have talked to other mechanics that have went through it with their customers and they fixed the issue with the Kia's before it gets to this point. Still has of now every two weeks I am buying $44 worth of oil to put in my car. Even from the advisor that I have been dealing with at Kia named Beau stated that my spark plugs issue was from the oil, and he always stated oh its getting close to the motor going out. Now my car is hesitating and its doing the same thing as it was before the new spark plugs except the check engine light isn’t on. I can’t afford to keep putting oil in it and constantly getting oil changes. Just from the receipt the Kia Manufactured attached isn’t the only time that I have been to Kia or contacted the manufactured company regarding this. It took me to take it to a different shop when I can’t stating to Kia the issue than finally they said it’s a recall on the car. It’s also a recall on the fuel pump and I advised them and still didn’t order the part or fix that as well. Still having issues now
