10/2021 Drove to store (about 20 minutes). Shopped for about 1 hour. Started to leave parking area and enter ramp to highway when the engine stopped. Everything went off. No warning. No check engine light, no maintenance light, nothing. I was able to steer back into the parking area. Put car in park and waited about 4-5 minutes. Started the car (it started without a problem) and began driving in the parking lot. when it began hesitating and feeling as if it would stall again. there was a gas station next to the parking area. pulled in & filled tank (tank was 1/2 full) and just barely pulled into a parking spot in front of gas station convenience store. Got towed to our local garage. They changed the oil and checked external systems and thought it was working fine. When my husband picked the car up it was still hesitating and almost stalling on the way home. Next, took it to local Kia dealer. Same situation. Couldn't find anything, said it drove fine for them. Same thing happened to my husband on the way home. Stalling in traffic. Having to restart the car in an intersection. Very dangerous. Brought back to dealer and they said it would cost $600-1000 to diagnose. Then it might cost $5000 - $10,000 to fix (replace or rebuild the engine). I reached out to Kia Customer Service but they did not offer any solutions other than to talk to the dealership in question. We are at a stand-still and have not been able to drive the car since October 2021.

I was driving down the highway going about 75-80 MPH, and my car started acting funny. No lights came on or smoking or anything to indicate something was wrong other then it acting funny. Pulled off the highway and my car died, had it towed (after waiting for awhile) got it towed to a AAA service center where they told me my engine was blown. Towed it back to Kansas (I was traveling on vacation when this happened and was 2.5 hours from home) to a kia dealership where now my car will not "throw the code" for the engine to be covered by warranty

- Newton, KS, USA

Kia dealer confirmed that the engine is seized, like a bearing. Has been approved for engine replacement under warranty and previous class action settlements through Kia. We were traveling down the highway at 80MPH in the process of passing another vehicle when the engine suddenly seized. No warning before hand; no noise, no overheating, nothing. Car was running normally. No warning lights came on. We lost all acceleration power. We were able to navigate traffic to the side of the highway where the cars engine quit and would no longer start. 2 hours stuck on the highway with traffic zipping by at 80 MPH, $300 tow bill.

This product continually needs oil. The engine smells all the time as though it may be burning. I have spent hundreds of dollars on oil. It is not able to have consistent oil changes due to there often times being no oil in the veh to change. The low oil indicator never shows. Also, The brake lights are constantly blowing out. On one occasion A bulb burned into its housing and had to be pried out in order to replace it. I have complained to Kia to no avail. It-??s stopped twice. Yesterday most recently. It started shaking and making a clinking noise and shut off. It-??s being towed to the dealership. Kia is aware of the fire potential and has sent written directives on where not to park.

On March 11, 2022 I was driving my 2015 Kia Sorento when the engine died. I was driving on a major road when all of a sudden my brakes locked up and all the warning lights and sounds went on and my car stopped. If it would have happened on the highway I could have been seriously injured. The problem has been confirmed by a dealer and an independent garage both saying that my vehicle needs a new engine. It has been meticulously maintained. Prior to the engine failing there were no warning lights indicating any low oil or service engine lights. The dealership stated that it was not my fault. I contacted the Kia manufacturer and they said there is nothing they can do because it is over the 100,000 mile warranty. It only has 110,000 miles on the car.

Car was sounding funny. Had recently did oil change about a week ago. I took car to Kia and they said I had recalls that needed to be done. Kia did all the recalls on my car and installed knock system. They called me to pick up car and the car shut off of them. Called Kia and they first approved the dealer to purchase the new engine. They then sent an email denying the purchase of a new engine. This has been going on for several weeks. They are saying engine had failed when car went to dealer but why would they perform work on a car's engine that already failed. They are refusing to fix car.

December 28, 2021 On Hwy 85 right next to Auburn, Alabama, on my way to Houston, Texas, I began to notice that as I accelerated with my 2015 KIA Sorento there was a sound as if my muffler had a hole in it. Within just a couple of minutes, the car wouldn-??t accelerate well. I then pulled off the highway onto a ramp and at the intersection the oil indicator light lit up and then the engine light and then there was a rattling noise and then the car quit. I checked the oil and it was a little bit low-??.not much though. A passerby took me in his car to an auto parts store where I purchased two quarts of oil. I put in the oil and started the car. The oil indicator light was now no longer on but there was a little bit of a rattling sound or knocking sound. The passerby said he knew a mechanic that was just a quarter mile down the road at a full auto service shop and that he would follow me if I wanted to take the car there. It was very close so I drove there. As I got closer the rattling/knocking sound got a little louder and then as I was about ready to pull in to the shop the car shut off and wouldn-??t turn on. I had the car pushed the rest of the way into the auto shop. The mechanics looked at it and said it was -??locked up-?? and would need a whole new engine. One mechanic said that KIA engines sometimes do this with little to no warning. I was shocked. I had never had any problems with my 2015 Kia Sorento before. It had now 96,000 miles on it and I only really had to do the oil changes every four months or so. A few hours later I had it towed to the KIA dealership in Auburn and they looked at it and determined it needed a whole new engine and new starter. The price would be $9,700 dollars. The KIA service people mentioned a Theta Engine Class Action Lawsuit that I might be eligible for. I filed a claim and the website showed that my VIN indicated I was eligible for this claim. I have been told KIA will make a determination on the claim in 60 days.

Car continually trying to over-heat. Had to keep pulling to shoulder every 1/4 mile or so, and letting car cool down again. Mechanic diagnosed as a head gasket problem, but upon further research it looks like it may have actually warped the engine block itself. When mechanic calls around to multiple junkyards, found many 2015 kia sorentos, but no engines available due to the same problem. Vehicle is at approx 133,000 miles, and Kia is stating that the vehicle is not in the extended engine warranties effected by this problem (apparently happens more so in another model of kia, I believe they said Optima, but I didn't pay that close of attention since my car is a Sorento.)
