I am unsure what part of my car malfunctioned. I had my foot on the brake when my car began to surge forward and accelerate itself, crashing me into a tree because the steering completely stopped working as well. It is available for inspection upon request. My safety and the safety of others was put at risk because I was in the middle of the street. The problem has been confirmed by an independent service center. A couple days after the incident, the same exact malfunction happened to an employee at the independent service center. The vehicle was lightly inspected by the manufacturer but there isn't a concise conclusion as to what caused the issue. There was not any warning lamps or messages before the incident. My airbags did not deploy during the incident even though there was significant damaged to the body of the car. A couple days prior to the incident, I was at a complete stop at a traffic light. As I had my foot on the brake, the car began to surge and jerk forward itself.

Since November 2025, this vehicle has experienced repeated loss of power, severe shaking during acceleration, jerking between gear shifts, abnormal humming/grinding noises, and multiple check engine light events. The condition is most noticeable between approximately 40-70 mph and has repeatedly occurred while driving on highways. On multiple occasions, the vehicle struggled to accelerate properly and would not respond normally to throttle input. During one occurrence, the vehicle had difficulty accelerating beyond approximately 55 mph while on the expressway. The shaking became severe enough that I feared mechanical failure could occur while driving. I was forced to pull off to the shoulder of the highway because I no longer felt it was safe. The inability to maintain speed and accelerate normally created a safety risk for both myself and surrounding traffic. The vehicle has been returned to the dealership six times for the same recurring issue. Repairs have included replacement of the ECU, catalytic converter, ignition components, fuel injectors, and other engine related components. Despite these repairs, the problem continues to return. The condition has been repoduced and documented by the dealership, and a manufacturer field technician was involved in the most recent diagnosis process. Most recently, after the vehicle was inspected and believed to be repaired, the check engine light illuminated again while the service manager was moving my vehicle to be washed inside of their garage, as I waited (today, June 11th 2026). The recurring loss of power, repeated check engine light events, and inability to permanently correct the defect raise significant safety concerns while operating the vehicle. I have all documentation in my notes, as well as the dealership repair documents.

*The end of March, my car suddenly started making an awful grinding noise, jerking, slowing down even with foot on excellerator. Towed to nearest Lia in Leesburg. Couldn't find anything wrong. Happened two more times didn't take in. Next time it happened in April towed in. *My engine was replaced in April of 2025. *Was fine until 12/10/25. Same grinding, etc. Was worse than before. Found out my 5 yr. warranty ended on 12/09/2025. Had it towed to Ocala Kia where I bought car. Updated software to what it was before replaced engine. Found out engine only had warranty for 1 year. That has expired. I thought I had purchased 5 year extended warranty when I bought out lease but I don't. So I don't know what I paid for. I do not feel confident that it is fixed nor do I trust dealer. *I have asked both dealerships to give me a written explanation on what they have tested for and dates and serial # on parts. I was told that info was only for dealer and won't let me know. I want to know if any damage to parts that were source of grinding. I have all or most of paperwork for service. I am taking car to another reputable auto repair to check it over for so I can decide to get rid of it. *I want to make sure it is on record that I have let you know that fixes haven't worked. Problem is sporadic and unpredictable. I cannot find out what they have checked. This was my last car. I like it but no longer trust it. [XXX] [XXX] CP [XXX] .

The car makes a jumping/jerking movement & at times, something that seems like a misfire happens. All lights go on and the car will do that jerking issue & become un drivable. This happened to me on the road and I was afraid for my safety as I couldn’t get my car to a safe place immediately. Brought it to my mechanic and he gave me forms of a recall regarding 2021 Kia Seltos which is what I have.

DEATH TRAP! Point blank~Engine will STILL Jerk, Skip, Not Do Anything Or even Shut Off Without Warning!!! The Driver's Screen will still Flash and go out but only once in a while now. Dealership didn't understand that. They told me Radio was Fine Now. I told them Screen Directly in Front of Driver's with Speedometer on it. IT'S HARD TO FIND GOOD HELP. EVEN HARDER, to FIND a SAFE RELIABLE VEHICLE that YOUR KIDS CAN BE IN!!! 💯% 🎯 RUST {definitely} up under Near the License Plate Bracket. ALSO, the Windshield WIPERS STOP WORKING WHENEVER THEY CHOOSE!!! The Best part is, the Dealership CAN'T DO ANYTHING about ANY OF THIS. Why? Pretty much because KIA REDID the TEST so that ALL the Vehicles PASS Now. It makes it LOOK like the Engines are OK, when in Reality they are 💩. I bought this Vehicle 12-30-24 with 44,068 miles on it. My Daughter and I thought we were going to Die in it on 4-26-25. We didn't even have it a full 4 months Before We Found Out WE HAVE A LEMON from KIA. There were 3,310 Miles put on it. Come on... I was told there was No Way to NOTE My Account at the Dealership for the Different Times {Everytime} this NEGLIGENT 💩 STUFF Kept and Still Does Happening. That's OK. I just Hope and Pray for KIA's sake, that Nothing Ever Seriously Happens to Anyone because of How THIS 2021 KIA SELTOS VEHICLE Operates DEFECTIVELY in So MANY DIFFERENT WAYS that ARE SAFETY HAZARDS. IF they were Smart, they would REPLACE ALL OF THEM with a Brand New Vehicle to AVOID A POSSIBLE SERIOUS FATALITY. I only say this because that's what WE experienced more than once. We fear this Daily. We ended up with this Vehicle after our Honda CRV-EXL was Totaled by Someone running a Red Light. It was the OTHER PERSON'S FAULT, but after paying off car... Kia was all in could afford. I had NO Choice but to get this KIA. Being a Single Mom on Low Social Security Disability Income, I did what I had to do! I have to have a GOOD RELIABLE AWD VEHICLE to get to Doctors Appointments. THIS ISN'T ONE.

[XXX] [XXX] [XXX] [XXX] 2022 Kia Seltos [XXX] 54,000 mileage I am reporting two serious safety defects with my 2022 Kia Seltos: Engine Shut Off / “Push Engine to Start” Warning: Date(s) of occurrence:[XXX] Location: Throughout Portland, OR Description: While slowing down and stopping at intersections, the vehicle starts beeping very fast, then displays the “Push Engine to Start” warning, and then shuts off completely, creating a high risk of collision. Cruise Control Unintended Acceleration: Date(s) of occurrence: [XXX] Location: Throughout Charleston, SC and Charlotte, NC Description: While cruise control was engaged, the vehicle accelerated without any driver input. This happens infrequently. On two occasions, I was on straight open roads and watched to see how fast the speed would increase - 80 mph and 100 mph. I used the brakes to stop the increase in speed. This is a severe safety hazard. The transmission stutters at low speeds, causing the car to lurch: Ongoing issue - a few times a month since purchasing the car. Previous Claims / Service History: I have previously filed a warranty claim for other issues with this vehicle. The current issues have been reported to the dealership but have not yet been repaired or reproduced. Additional Information: No video evidence is available, as the events are intermittent and stop before a camera can capture them. I am concerned for my safety, the safety of passengers, and the safety of other drivers. Action Requested: I request that the federal safety agency review this complaint for potential safety investigation and recall consideration.

We first noticed that the car was sputtering and jerking when accelerating at highway speeds. It wasn't consistent at first but continued to get worse over time and at more regular occurrences. White/grey smoke was spotted from the tailpipe whenever the vehicle was accelerating, either from a stop or when "resuming" on the cruise control. We brought the vehicle in to the dealership as the "service engine" light came on and explained what was happening with the car. They told us that there was an "intake valve" that was plugged and need to be replaced and that the on-board computer needed to be updated. We also had some routine maintenance done as well and they sent us on our way. Quickly after getting the car home we noticed that the original problem persisted and actually got worse. We checked the recalls on our car and noticed that there are other recalls on other VINs for the same Make, Model, Year and engine type as our car and the symptoms of those recalls were exactly the same as our symptoms in our car. We returned the vehicle to the dealership and again the "service engine" light had come on. This time they got the code that says something to the effect of "cylinder scoring" and that we needed to have the engine replaced. The recall for the 2.0L Nu engine for 2023 Kia Seltos' that doesn't currently include the VIN for our vehicle is SC336. We had to replace the engine out of our own pocket and would like to see this VIN included in the recall that affects other vehicles of this similar Make, Model, year and engine type.
