My oil light has been coming on and blinking then disappearing. Current on oil change and oil level is full on dipstick. Noticed little oil stain on driveway but oil level remains good and full. A couple times now my car has lost acceleration. One time on the highway and once in my neighborhood. When I press the gas it does not accelerate. It will lose speed and after a few times of stepping on the gas will eventually get to speed.

Engine began making very loud noised while driving on an expressway. Pulled off of the road and engine would not start. Had to get towed to a local repair shop. I found out that my engine is blown. There have been recalls on the Theta II engine, but, mine was not involved in the recall. There are many reports of these engines that were not involved with the recall having MAJOR issues. Please investigate further into these engines.

We believe the connecting rod bearing in the engine is bad and needs to be replaced. The vehicle is available for inspection upon request. When the engine failure occurred, luckily we were in a neighborhood and not traffic because the engine speed was drastically reduced and the vehicle failed to accelerate in a reasonable manner. The vehicle has not been reproduced or confirmed by a dealer, but a home computer diagnostic was done on the vehicle giving a "Cylinder 3" misfire code. The vehicle has not been seen by anyone other than the owners of the vehicle, we are currently in the process of trying to get an appointment with a kia dealership. There were no warnings prior to the failure, but as soon as the failure occurred, the check engine light turned on and was blinking.

While driving as normal on the way home the engine stalled and would not pick up as I was getting on the highway with traffic behind me. I was able to get on and begin doing 50-55mph getting good onto the highway and pick up speed trying to get to 60mph never got to go past 55 as the car slowed down instead of picking up speed. EVERY warning light popped up onto the dash as I panicked to get off the highway unable to pick up speed and move out of the way of flying cars it slowed down to a complete stop I had just made it off the highway onto the side of the highway with cars flying by the grace of God my kids were not with me. I was not able to start the car up and had no idea as to why it happened I had no issues with my car and just brought it from Crown dealership not even a full 2 years of having the car. It was confirmed by a licensed mechanic that the engine is gone and no known reason as to why. The manufacture states it is beyond warranty as the car was purchased from crown they keep telling me to call and speak to Kia. Kia states it has no recall because of my VIN. I am not the first and not last to have this unexpectedly happen. I keep the up oil changes, tune ups, new tires and more done. now to know the engine is gone an it is not my fault no help and additional 5,000 for repair I am still making payments on the car and can not even drive it. I could have died on the road or highway due to the car just stopping on it own while driving the warning lights didn't come on until after the car was done going. I had no choice but to get over quick still risking to get hit and unable to do or know anything. This is crazy how you can take car of the car and not be able to do anything other than pay more on the car that was not even close to the total being added on now. The lawsuit filed I should have called for help because now I am stuck and blessed not to be hurt or killed due to this issue.

While driving the car on 5/14/2021, the warning light came on and in 30 seconds, the engine quit. The car was taken to Steve's Tech Senter, Foley, AL. The starter was replaced and still would not run. Steve told me the engine was seized up. I contacted Team Gunther Kia, Daphne, AL, and was told by Cassandra that the car was not under warranty because it had 130000 miles and I had missed the deadline on the recall notice. I have never been notified of a recall notice on the car at all. I did receive a Northern California District document telling me of a class action suit settlement (approximately one year ago). I had no problems with the car at that time and did nothing. There was a timeframe for reporting of 4/12/2021 to the their document which also stated that the engine warranty would be extended. I had no hint of a problem with the car until the engine seized on 5/14/2021.

On 5/27/2021 I stopped at a red light. When safe to proceed, I turned right. Within ten yards, the car slowed, a "hybrid system malufuntion" warning was displayed, and all power was lost. Car towed to Kia of irvine, where safety plug assembly, hybrid battery, and complete fuel system service were performed, total cost to me $1,647.31. Kia technical operations document PS515 appears to state fuse installed by Kia originally improperly rated at 125 amp, as it is replaced with 150 amp fuse. Why is this not a tsb, and thus a repair covered by warranty?

I have had my vehicle for 3 years. I have never has any problems with this vehicle. Almost two months ago, my vehicles engine seized while I was driving on the highway with my four children in the vehicle. I had the vehicle towed to Clay Cooley Kia in Irving, Tx. They went on to tell me that they have to fix the other recalls with the vehicle before they could summit anything about my engine which also has a recall on it. After 30 days of having my vehicle, they told me that they could not cover the recall on my engine because I have a salvage title. I was told by their own employee, that it should not matter if my vehicle has a rebuilt title or not. They are being very rude to me and refusing to get me over to higher people at the company as a result.

Vehicle is burning oil very fast and reving up uncontrollably. Was informed last summer of a recall on engine. Toon vehicle to Kia and they confirmed the vehicle engine was burning oil way too fast. Vehicle was burning oil almost completely empty in only 1,000 miles. When I finally took the vehicle back to have Kia uphold the recall I was told that they updated the recall 2 days before my appointment and they would no longer fix my engine despite discovering that there was an extreme oil consumption malfunction. Have talked to many people and was told by Kia to contact the better business bureau if I was not happy with their decision. Have been in contact with multiple people since last summer and keep being told that they would get back to us soon. Received a call today saying that I could pay to get a new engine and then when they finally make the recall they would pay me back if they could prove that I needed a new engine because of Kia
