Mileage when the problem started
Owner reports
Selected complaints filed with NHTSA by 2023 Kia Seltos owners, lightly cleaned up (personal details are redacted by NHTSA).
I had two incidents with the Kia listed above involving the feature where the engine stops when at a light, and then turns back on when foot is removed from brake. The first instance happened in a parking lot while I was maneuvering into a spot. The accelerator sensor sent my car forward at a high rate of speed, and I missed a brick wall by inches. The second incident was much the same, maneuvering into a parking spot in my apartment building. Spaces are very tight and there is a lot of stopping, reversing, going forward. Again, I took my foot off the brake and the accelerator sensor sent my car speeding into the car parked in front of me. I did serious damage to my neighbor's car and go mine. I can turn off this feature, which I now do.
The contact owns a 2023 Kia Seltos. The contact stated that while driving at 10 MPH, there was an abnormal fuel odor coming from the vehicle. The vehicle was stopped, and the contact became aware of smoke coming from the engine compartment. A dealer was contacted. The vehicle was towed to the dealer to be diagnosed, and it was determined that the catalytic converter, turbo, and engine needed to be replaced. The vehicle was not repaired. The contact associated the failure with NHTSA Campaign Number: 25V099000 (ENGINE AND ENGINE COOLING); however, the VIN was not included in the recall. The manufacturer was notified of the failure but offered no assistance. The failure mileage was 62,000.

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. …
3 times in the last 24 hours my vehicle has completely stopped while in motion. Once on the highway and twice in residential areas. There was no precursor problem to let me know this would happen, no strange noises and no check engine light. It just fails and the engine stops while I'm driving. It's extremely dangerous and quite frankly very scary. When I called kia today to tell them what happened all they said to me was that since the check engine light wasn't on, that it was safe to drive and they couldn't get my car in for several weeks. Then the other kia dealership in the area said they would get me in next week but again that my car was safe to drive. It is most certainly NOT safe to drive!! This is happening while I'm driving and in motion. Twice at about 10 mph and once going 60 (thank god nobody was behind me)
Issues with idle stop and go. On 11/8/23 was at a light and stop and go was on. Light turned green took my foot off of the break and nothing happened then engine staled. Check engine light came on and then all other panel lights. Took two tries to get engine started again. I was in a busy intersection at rush hour. This is a huge safety issue. It has clitched at other times where took foot off break and engine took a moment to restart, but this is first stall. I now have a note in car to turn off every time I drive. I live in a high density area with lots of stop and go traffic and lights and cannot afford to get stuck or worse in an accident because of this. Kia needs to address this issue.
Car has stalled 3 times after driving short or long distances in hot weather (near Great Lakes, not even southern heat). Twice in 2024 and once in 2025. It is 2023 Kia Seltos with only 10,000 miles. Dealer inspected it 2024 (possibly not knowing of other recalls) and said nothing wrong. It's the turbo engine, while I see the regular engine versions have a recall. Could be the rings, crankshaft sensor, ISG, electric oil pump controller, etc. It stalls while at a red light or stop, and is dangerous if on a hill as it does not accelerate and starts to roll backwards when take foot off brake and step onto gas pedal. It has also stalled in traffic on a bridge and then needed to be restarted.
My 2024 Kia Seltos, with approximately 50,000 miles, experienced a sudden shutdown while traveling at highway speed, cannot accelerate. The dashboard warning appeared as no key not detected and the brake pedal became extremely hard, making the vehicle difficult to stop. The vehicle subsequently restarted normally. This is a serious safety concern. I am requesting a thorough investigation into the cause of the shutdown, including the main electrical system, power distribution, engine controls, and brake-assist system. Please document this as a highway-speed shutdown with loss of normal braking assistance and provide a written diagnostic report before releasing the vehicle.
Dear, I own a 2024 Kia Seltos and have experienced a recurring issue. While driving, I stopped at a red light, and the vehicle's automatic stop system activated as usual. However, when the light changed and I pressed the accelerator, the vehicle completely shut down. To restart it, I had to turn the key to the "Off" position, shift to "Parking," and then turn it back on. This issue has occurred four times now, and I'm concerned it may compromise driving safety. I would appreciate your guidance in resolving this matter. Looking forward to your response. Best regards, [redacted]
