2023 Kia Seltos electrical problems

Filed Oct 19, 2026 · Brakes, Electrical · TX

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.

To the federal safety agency, I am writing to formally submit a safety complaint regarding my 2023 Kia Seltos, which exhibits a recurring, dangerous defect involving the engine stalling without warning. This defect results in a total loss of power while the vehicle is in operation or attempting to accelerate, posing a critical safety risk. The failure manifests in two primary scenarios: * **Remote Start Failure:** The vehicle frequently stalls immediately after utilizing the remote start feature when shifting into drive. * **Auto Start/Stop Instability:** The Auto Start/Stop system contributes to the engine shutting down unexpectedly when lifting off the brake or attempting to accelerate from a stop. When this occurs, the dashboard illuminates multiple warning lights (e.g., battery, oil, "key not in vehicle"), and the vehicle loses all forward propulsion. On inclines, this defect causes the vehicle to roll backward, forcing the driver to rely solely on emergency braking to prevent a collision. ### Evidence of Widespread Concern My research indicates this is not an isolated incident; numerous Kia owners report identical, dangerous symptoms: * Drivers across various models report the engine shutting down and the vehicle rolling backward on hills, requiring a full power cycle to resume operation. * Some owners report losing all ability to accelerate at traffic lights, accompanied by critical dashboard warnings. * Others report the vehicle shutting off on its own while driving or refusing to start despite the dashboard indicating it is running. I have attached evidence documenting these experiences: **image.png**, **image_2.png**, **image_3.png**, **image_4.png**, and **image_5.png**. Given the frequency of these reports, I urge the federal safety agency to launch a formal investigation into this apparent software or engineering failure. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The gages fall all the way down, I’m not able to accelerate, engine light, traction light, tire pressure light, crash detection light, and other lights come on and prevents me from being able to drive. This happened on the interstate and almost caused an accident.

Incident Date: October 26, 2025 Summary: On October 26, 2025, while merging onto a highway at high speed, the vehicle experienced a sudden and total electronic safety system failure. Without driver input, the Forward Collision-Avoidance Assist (FCA) system engaged the brakes (phantom braking), causing a dangerous, unprompted deceleration in active traffic. Simultaneously, the Electric Power Steering (EPS) assist failed, making the steering wheel extremely heavy and difficult to maneuver while trying to merge. Dashboard Alerts: The instrument cluster displayed a "Check Forward Collision-Avoidance Assist system" message, and the following warning lights illuminated: Master Warning, ABS, Traction Control (ESC), and Forward Safety. Attempted Remediation: I pulled the vehicle over and let it cool down for over an hour, but the warning lights and system failures persisted upon restarting. Per manufacturer-recommended troubleshooting found online, I thoroughly cleaned all exterior sensors and was forced to manually disable the collision-avoidance and alert systems via the vehicle's computer settings just to be able to drive the car home safely. Current Safety Concern: Since this event, the vehicle has exhibited increased skidding and inconsistent traction during normal driving conditions. This instability occurs on any road at any time, specifically when performing routine turning maneuvers, and is not limited to winter conditions. This suggests a deeper mechanical or software failure within the ABS/ESC/AWD control modules that cannot be resolved by the driver. This VIN currently shows no active recalls, but the symptoms match the known defects in the SC275 and SC336 campaigns exactly.

Vehicle acts like it’s going to die. No maintenance lights well maintained. Rattle noise and acts like it’s misfiring. Went to turn at traffic light and almost got into a wreck due to no horse power. This has been happening since less than 40,000 miles but car dealership keeps saying “nothing is wrong” because there isn’t a warning light on! It’s getting worse!

One night I started my car and my screen on my Kia seltos had a bunch of gibberish on the screen and then I went to power off the radio and tried to power back on and screen wouldn’t turn on and one usb won’t work. Tried to hard reset and check fuses and still no luck. I keep reading a bunch of people saying how they had same issues as I did on my radio . My friend is sales guy at car dealer and he told me not first time a radio on a Kia took a poop. So how comes there is no recall yet on this part of the car. It’s crappy because warranty on radio is only up to 36,000 . And my car I have only had for 3 years almost and I have 50,000 miles on it now . After disconnecting the battery and plugging back in like the dealer told me to do and now I have a loading symbol behind my wheel on the dash

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.

On 4 different occasions my vehicle applied the brakes forcefully on its own at high speeds. The dash flashed with the message "check forward collision avoidance assist system." as well as displayed the following icons: master warning light, hill climb assist, traction control, forward collision, and the Auto start/stop was flashing. These continued until I was able to stop and turn the car off. When I was trying to slow down and stop my brakes were not working correctly as I had to push the pedal all the way to the floor for a long period to stop all the way. When the car was put in park the engine was revving up until it was off. The car was towed to the dealership after first incident and the following codes were in the history: C164202 C161308. Dealership had my car for 6 days, opened a tech line case and without an answer of why this happened nor remedy, my car was released back to me resulting in 3 additional instances. It is now going to another dealership to hopefully get an answer and repair.

Unknown. Was told there was a recall when i took it in for my first oil change over a year ago, was told that they would call me when the part came in, then never heard from anyone. Just took it back in couple months ago and mentioned it again and nothing was ever said. They did confirm that it had a recall but werent too concern about it
