    My 2021 KIA Sorento, has literally cut off on me several times in the last 3 three months, when I am at a stop ight/sign the vehicle will just shut off, it will not turn back on, after 3-4 attempts of trying to get the vehicle to start it would, but later on the same day it would do the same thing. On the third incident I took the vehicle to the Kia dealership in Victorville, Ca. After keeping the vehicle for several days, they said they could not find anything wrong and that i should replace the battery because it had a low cell. So I bought the battery and paid for the diagnostic. the same day I picked of the vehicle drove to Las Vegas , Nevada, the vehicle did the same thing it would not start, we had to get a jump to get it started, was terrified to drive the vehicle back to California. Call the dealership about the issue but never received a call back. Now here it [XXX], the vehicle cuts off at a 4 way stop light, we were in the turning lane!!!! the vehicle would not start, there virtually no power, had to move the vehicle to a parking lot around the corner, called a tow truck and had the vehicle towed to the Kia dealership. They are saying it will take 3-5 days before they can get a diagnosis done. There is something going on with this vehicle, and I do not feel safe driving it even a short distance. This problem needs to be investigated before some get hurt/accident. I have not a seen a recall on my VIN number but there is something on wrong very similar to the transmission problems the Kia is having. I would like to have this issued looked at immediately to find out the root cause of this problem with a resolution. Will be awaiting a response, my vehicle is still at Valley Hi Kia, Victorville, Ca INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

    Today, our vehicle began making a chiming noise and displaying the words "Stop Safely Immediately." We were nearly in a car accident as our car stopped working in the middle of the road. We had to abandon the vehicle because it would not move. Upon coming home, we searched our VIN and found that there was a recall on the vehicle that Kia had never informed us of: SC250. Kia is mandated to inform clients of recalls that may endanger them, yet Kia chose not to do so.

    I was driving my car on Friday, September 29 at approximately 12:30 pm. As i was driving the vehicle ot started to feel as though it was jerking and stalling while driving in driving on a busy road. I reached a parking lot and pulled over and shut the car off when i restarted it a warning came up on my infotainment system that there was a promblem with the transmission and i needed to contact my dealer immediately. The check engine light also came on. I own a 2021 Kia Sorento with 11,712 miles. I was afraid to drive vehicle after this incident as I feared for my safety.

    My 2021 Kia Sorento X-Line Prestige comes with Driver Assist features. One is for steering. Without warning it will disengage, particularly on a 2-lane highway, or when entering a curve in the road. This is dangerous. It needs to come with a warning that Driver Assist can flake out on 2-lanes and on curves, and is fairly useless unless you are on a straightaway on an interstate. This has happened to me multiple times since I bought the car from the Heiser dealership in Wisconsin.

    My 2021 Sorento randomly gets stuck in between gears, slipping into neutral and rev'ing up to 4000-5000 rpms. This is at lower speed usually within a mile or so of leaving my house. It's very frightening and has happened to me dozens of times, but I live in a rural area over an hour from a Kia dealership, and they do not offer loaners. This issue first arose for me after the transmission oil pump recall was already addressed. I am the 2d owner, and suspect this could be why the previous owners sold the car, which I bought through Autotrader from the Heiser dealership in Wisconsin. After the latest episode, I finally arranged alternate transportation and took it in to the Serra Kia dealership in Jackson, TN. They have had it over a week and not been able to replicate the issue so far. No computer codes show up on it either. They say there's no technical advisory on the issue, and have no idea what's going on with the transmission. Serra Kia is saying that Kia corporate will not approve replacing the transmission without an error code. From reviewing other owner reviews in Kia forums, the Kia 2021 Sorento slipping into neutral while driving appears to be an issue for others as well. It is dangerous, as I could be rear-ended. Quite honestly, it’s terrifying, and I am afraid to drive the car again without this issue being addressed.

    The automatic start/stop function (ISG) stopped functioning. The light turned from green to amber and flashes intermittently. When the light is flashing the vehicle has a loss of power. On 8/28/23 I was accelerating to get on the interstate. Suddenly the speedometer dropped from 40 mph to 24 mph. I had to quickly exit the on ramp as to avoid being hit from behind by a huge white pickup truck. I drove the side streets, staying under 40 mph, to the dealership.You cannot disable the ISG at this time. There is no warning of when this may happen. I've had it in the dealership 3 times, 8/10/23, 8/24/23, and 8/28-9/16/23. The first two times they could not replicate the problem, so nothing was done. On the third visit a high pressure sensor was ordered and replaced. The ISG is still malfunctioning. Now the ISG kicks itself back on after it has been disabled. The light is still amber, not green, indicating there is still a problem. Loss of power has happened twice 6/25/23 and 8/28/23. I have service reports and videos of flashing lights. Unfortunately, I was not able to load at this time.

    My Kia Sorento has the Nightfall trim package on it and currently has 13K miles. The paint on the trim around the windows has started to come off, sort of looking like acid rain effect. The dealership said this is not covered as it is an environmental and wash problem. We live in Hawaii. However, this is a widespread issue with Nightfall trim packages on Kia vehicles all around. I believe it is a manufacturing defect. Even if it is a wash or environmental problem, there was no warning when buying it could happen

    I had reported a momentary loss of power when driving the first time I took my vehicle for an oil change. Dealer said the car was just getting accustomed to my driving habits. I said I was in an intersection and the car lost power for a moment and I was almost rear-ended. It has happened many more times and it seemed as though it usually happened between 25-30 mph. Recently it has become more frequent. It’s happening at all speeds. Yesterday it seemed like it was choking like when you’re out of gas (it had 3/4 tank of gas). Today I was making a turn at a heavily traveled intersection, when rounding the corner vehicle lost power then banged into gear. I’ve never heard it bang like that before. Seems to be getting progressively worse and I’m now concerned for myself and others safety. I work 45 miles from home and depend on this vehicle. This is my 3rd Sorento and have always liked and recommended them. I’m making an appointment for a diagnostic service soon but can’t afford to be without my car. I saw there was a recall for “loss of power” but my VIN isn’t included. Please help.
