KIA Seltos electrical problems

ELECTRICAL SYSTEM

My 2024 Kia Seltos (leased, approximately 19,800 miles) received an over-the-air (OTA) software update on [07/03/2026]. The vehicle's screen prompted me to approve the update and stated it would complete with the ignition off. I approved it and exited the vehicle as instructed by Kia's on-screen directions and owner's manual. Immediately after this update, the vehicle developed an intermittent no-start condition, and the 12V battery went completely flat, accompanied by an ESC (Electronic Stability Control) warning. The vehicle had no electrical or starting problems of any kind before the update. The vehicle was disabled and could not be started without a jump start, which is a safety concern — this could strand a driver in an unsafe location or in extreme weather. The dealer (Car Pros Kia Glendale, RO #531279, dated 07/25/2026) performed a full system scan, found no DTCs, and confirmed the 12V battery failed testing. The dealer's repair order documents the customer complaint as "intermittent no start condition and battery went completely flat after the software update." The battery was replaced at my expense. The vehicle's software version after the update was NNK-02-0118 (previous resident version NNK-02-0108). Kia America has acknowledged partial responsibility by approving a 50% goodwill reimbursement. I am reporting this because a manufacturer-initiated OTA update that discharges the battery and disables the vehicle is a safety defect that may affect other vehicles.

My Kia has been stalling, shaking, and just driving extremely badly for the past year. This day, I was driving on 55, and the car just stopped and stalled in the middle of highway near Berwyn, IL. This was extremely dangerous and could have honestly been life threatening. I pulled over, turned the car off and on, and was safely able to drive it to Berwyn Kia. Unfortunately, this was not the only time that this has occurred and I’m assuming will not be the last. In addition, I was charged $500+ to replace piston rings that were recalled on other models that were not recalled on my model, even though the same year was recalled.

ELECTRICAL SYSTEM

My 2022 Kia Seltos is equipped with Idle Stop & Go (ISG), which shuts the engine off when stopped and restarts it when the driver releases the brake/presses the accelerator. ISG stopped functioning about a year ago (the engine stayed running at stops). I didn't think anything of it because the ISG had worked sporadically from the day I bought the car. (I purchased it new.) It began working again, sporadically, about a week ago. Since then, on 3 occasions, when stopped at a red light with the engine auto-shut-off via ISG, pressing the accelerator to proceed causes the engine to fail to restart as I accelerate, and the vehicle stalls. The dashboard displays a "Press Ignition Button" message. I lose power to the engine, and the vehicle stops accelerating, coasting briefly on momentum until I manually restart it via the ignition button. I have not confirmed whether warning lights were illuminated, as my focus was on regaining control. This appears consistent with documented ISG restart failures reported by other Kia owners online, suggesting a possible pattern rather than an isolated defect. I checked my VIN on NHTSA.gov; zero open recalls. Kia customer care was closed when I called (today is a weekend day). I plan to call on Monday for a diagnostic appointment. This is a safety concern because the stall occurs unpredictably at the exact moment of accelerating from a stop, particularly hazardous at intersections in traffic.

To the National Highway Traffic Safety Administration (NHTSA), 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 NHTSA to launch a formal investigation into this apparent software or engineering failure.

ELECTRICAL SYSTEM

The infotainment head unit display system suffers from persistent firmware connectivity defects that cause severe system lag, complete screen freezing, and constant Bluetooth/phone disconnections. This directly compromises vehicle safety by rendering mandatory hands-free voice operations completely inoperable while driving, creating an intense electronic driver distraction. Furthermore, the system instability occasionally causes the central display screen to lag or fail to transition, impacting the reliability of the backup camera display. The manufacturer (Kia America) does not provide a functional consumer download path to patch the firmware build, and the local franchised dealer (Arapahoe Kia) explicitly refuses to service or update the component, leaving the vehicle with an ongoing electronic defect.

Under extremely cold temperatures, approx 10° the main display does not work. The MPH & other vehicle information will not display. KIA service requires the vehicle to be brought to the facility while condition exists in order to troubleshoot, however once the vehicle warms up, the non functioning display begins to operate normally and the problem does not exist. Speaking with the service advisor and service manager in charge, they are aware of the problem and know of other vehicles with this display problem.

ELECTRICAL SYSTEM

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.

ELECTRICAL SYSTEM

While driving in traffic, my 2024 Kia Seltos suddenly shut down without warning again. I lost propulsion while the vehicle was in motion with passengers inside, creating an immediate safety hazard. The issue appears electrical or powertrain-related. This occurred during normal operation and could result in a serious crash. My vehicle shutting down in active traffic with passengers is unacceptable, and there is no recall remedy in place to correct this hazard. I am requesting a manufacturer-level resolution under Ohio Lemon Law and the Magnuson–Moss Warranty Act.

ELECTRICAL SYSTEM

The dashboard goes completely black and will not work when it is really cold outside. This is a dangerous problem because I cannot see my speedometer, how much gas I have in my car, or the engine temperature. I have been to the Kia dealership 3 or 4 times for this problem and have them report it to Kia. They always tell me that they cannot replicate the problem so they cannot fix it. I have video evidence of this happening and have showed it to the dealership. This has happened now for 2 winters. There have been no warning messages or anything before this happens.

When the temperature is around zero my dashboard will not come on. I have been to the dealership 5 times for this issue. It takes me an hour to get to the dealership and by the time I get there it comes on. Dealership (Ken Ganley) states they can’t find the problem if it’s on. This is total bullshit, they know they have an issue and can fix it. Bought the car brand new. I believe it’s a safety hazard when I have no speedometer, gas guage or indicator lights. This has been going on since I purchased the vehicle in July 2024.

Instrument cluster does not turn on upon ignition, when in cold weather. this has been a repeating incident, first of which started only 2 months after the purchase. even after 7 separate incidents, and handful dealer visits, car was deemed "okay" because they could not replicate the issue. employees at the dealership have taken pictures and videos but have yet to find a solution to fix this issue, and they further "ask" that if the incident happens again, drive as is so they can see the issue. this is a serious safety issue since nothing is visible including speedometer, rev meter and gas tank indicator, etc. the most recent incident will be dated on the report, but i will attache multiple pictures from different dates as i can recall and recollect.

ELECTRICAL SYSTEM

Piston oil ring recall update complete in July 20 25. A month later key fob battery dies. Replaced key fob battery every other month since recall. September 20 25 had brakes and rotors changed at dealership since then anti-slip alert has triggered twice on dry roads. Light comes on then immediately goes off. Remote car starter stopped working in December. Dealership had no resolution for key fob issues and has not been able to replicate anti-slip issue. Dealership currently has vehicle to attempt to replicate issue and to look into the remote car starter issue. This is unsafe because the car automatically shutters and feels uncontrolled slip comes on also causes issues when key fob consistently dies every other month and get alert, letting me know that the key fob has died. And while the remote car starter is not a safety issue, it is all tied in with the electrical issues that are happening. The issues started after the recall was added to my vehicle.
