The Integrated Thermal Management System (ITMS) failed/ malfunctioned. Available for inspection. My car completely lost power on the interstate and it was 70 mph speed limit, I had a semi behind me. I-??m taking to the dealer when I-??m off in 3 to 4 weeks. Problem has been reported by other owners, as well as Hyundai Sonata N-Lines. Also video evidence. Not been inspected yet, but that-??s the problem. No warning lights. Could see the temp gauge moving up when I accelerated. Problem happened when it was cold outside, popped the hood and engine wasn-??t overheated at all, ITMS failed.

Within 2 months of buying the car, it has stalled in traffic twice with engine revving. During the first time, it was unnoticeable until my car did not react when pushing the gas pedal. The car stayed at a stop until I restarted it twice. Kia dealership was informed, however, they could not find an issue or code. Recently, the second time was different and more scary. It stalled once again and as soon as I noticed, my car would not accelerate and started rolling and revving with high rpms. I immediately put my hazards on in the middle of a 5 lane road in heavy traffic and was able to let the car roll into a parking lot. I left the car there, turned off, for 30 minutes before restarting it to have someone follow me back home. During this scary trip, the car shook violently and my foot was to the floor on the gas pedal and the car still would not accelerate unless on a slope. A five minute drive turned into a 25 minute trip while backing up traffic. (So, very high rpm-??s, slow to almost no acceleration, shaking and revving, NO engine light or warning lights triggered). Engine continued loud revving and moving idle in park that evening. Since then, car has been in mechanic once again with no solutions, codes, or lights to help the dealership figure out the issue because they say -??it-??s driving perfectly now-??. They are the only ones to inspect the vehicle each time.

While you're driving you hear weird squealing sounds and when you slow down the transmission tends to rattle. 2: After you start the car, there is a very loud sound like track and the car tends to move back and forth.

On December 28th 2022 between the 6:30 am to 8:00 my car was parked and caught on fire. I have filed a complaint with Kia and since then I have gotten the run around about them looking into the vehicle and seeing what cause the issue. My car was still under the manufacture warranty

The transmission is experiencing a loss of power and getting heavy/stuck at about 20-30 mph before It begins to accelerate somewhat faster. The car is also not accelerating properly. Engine light came on as this began. Oil changes on vehicle are up to date as well

I was traveling normally, exiting a highway ramp when my car acceleration system malfunctioned. It seemed as if it was a power train issue or engine issue. I was not able to accelerate or slow down properly due to this malfunction and it caused me to crash. My car was totaled.

Randomly, the cars engine rev is really low, it-??ll go up down up down over and over and over and then shut off, sometimes while in motion. Other times, when you-??re finished driving and you shift into park the engine will shut off the moment you hit park. My safety is at risk due to the fact that when I was in motion and it did that it could-??ve caused an accident. The dealer claims they are unable to re-create the issue, even though I am video recording proof. Many warning messages appear on my dashboard when this happens, but they all go away. Once you turn the car fully off and back on.

I bought a 2022 Kia K5 on 06/18/2021. On 12/31/2021, the check engine light came on, it shows code P088000 in the Kia Access app. Transmission control system issue. It started to jerk slightly when shifting into reverse. The engine is working twice as hard as it should when trying to pick up speed, using gas at double the normal rate. It will not downshift unless I actually release the gas pedal so it runs at high rpm's at all times. Driving at 55-60mph, the rpm's are at 3-3.5K and it will not downshift at all. (Unless the gas pedal is released). I have called for a service appointment, and my dealership (Joe Myers Kia/Imports) in Houston, TX. And there is a 2 week service wait. I was told there was nothing they could do, they do not have loaner cars any longer. I have to wait to get the code diagnosed.
