2024 Kia Sportage electrical problems

Filed Oct 21, 2026 · Electrical, Engine · AR

The vehicle experiences an intermittent, severe safety malfunction tied to the Idle Stop & Go (ISG) auto-stop system. When brought to a complete stop at intersections or red lights, the engine shuts off normally to conserve fuel. However, when releasing the brake pedal, the engine completely fails to auto-restart and stalls out in live traffic. The vehicle locks up, flashes an error message on the instrument cluster instructing the driver to shift to Park or Neutral to restart, and requires a hard manual key cycle to get the vehicle moving again. This intermittent defect has occurred over the past year, creating an extreme hazard for rear-end collisions in high-traffic intersections. The component is available for inspection upon request. The vehicle was presented to an authorized dealership on October 21, 2026, at 31,985 miles specifically for this stalling defect. The technician documented the complaint on the Repair Order but was unable to duplicate the stalling during a brief road test, noting that values were within factory specifications at that moment and taking no repair action. The manufacturer has not yet issued a recall or permanent remedy for this generation of vehicle stalling.

1. COMPONENT & INSPECTION: Electrical System / CAN-Bus network architecture and gateway modules. The vehicle and parts are available for inspection upon request. 2. SAFETY RISK: The CAN-bus drops communication while driving at road speeds. Critical safety systems—including Forward Collision-Avoidance, Blind-Spot Monitors, and Electronic Stability Control—instantly shut down mid-trip. Losing active stability and driver assists while moving on public highways poses an immediate, severe crash hazard to myself and others. 3. DEALER CONFIRMATION: Yes. An authorized Kia dealer scanned the vehicle and confirmed multiple logged historical network communication error codes (U-codes), verifying a system-wide network failure. 4. OTHER INSPECTIONS: Inspected only by the Kia dealer technician. However, because the failure is intermittent, the dealer simply cleared the fault codes and released the vehicle without performing physical diagnostics or repairs. Kia America Corporate opened a consumer case but has since ghosted all communication. No police or insurance inspections have occurred yet as a crash has not yet happened. 5. WARNING LAMPS & FIRST APPEARANCE: No advance warnings occur. The failure happens instantly mid-drive. Symptoms include a sudden, simultaneous "Christmas tree" illumination of warning lights (Stability Control, Braking, and Lane Assist). These symptoms first appeared in September 2026 and recur intermittently.

My 2024 Kia Sportage X-Pro Prestige has experienced at least 3 intermittent, unexpected engine shutdowns while driving or in traffic. The cause remains unidentified. The first occurred before [XXX] (exact date unknown). While stopped at a red light in Drive, I realized the vehicle had completely shut off. The engine was not running and all screens/displays were black. There was no warning. On [XXX], the same failure occurred without warning at approximately 60 mph during a longer highway drive. The engine shut off and all screens went black. I nearly collided with an 18-wheeler. No collision occurred. I was directed to call 911, and the vehicle was towed from the highway to a Kia dealership. The cause was not diagnosed. On [XXX], during a long-distance drive from Asheville to Wilmington, NC, the vehicle again shut off while I was still in Drive and slowing normally toward a red light. Warning lights/chimes appeared and the engine shut off BEFORE I shifted to Park. After shifting to Park, the display stated, “Auto Stop is Off. Shift to P or N and start engine manually.” I restarted the vehicle. A picture documenting the vehicle immediately after this event is included in my attached evidence packet. The cause remains unknown despite extensive testing and Kia Tech Line involvement. On [XXX], I drove approximately 40 minutes with a Kia master technician and diagnostic flight recorder, at speeds up to approximately 80 mph; the failure did not reproduce. On [XXX], I was told Tech Line wanted me to drive the vehicle for approximately 2 weeks with a flight recorder to capture another occurrence. After these repeated shutdowns, particularly the ~60 mph near-collision, I no longer feel confident driving the vehicle or transporting my family while the cause remains unidentified. I am concerned another shutdown could occur where I cannot safely avoid a collision. Detailed chronology and supporting evidence are attached.

I purchased a used 2024 Kia Sportage EX Gas that showed signs of trim peel at 5,000 miles. My extended warranty said they do not cover trim. I noticed multiple cars in our parking lot experiencing the same issues on 2024 or older models. In addition, the low gas indicator does not appear on the infotainment system after the Kia Connect expired despite gas being as low as 32 miles projected (avg. 24 mpg normal range). The Sportage lane assists yellow indicator comes on sporadically when changing lanes without or with the turn signal on. The steering assist will turn off when you go through a intersection and is not reliable enough to even turn on as it will give you a false sense of protection and intimately turn off.

Sudden Unintended Acceleration – 2024 Kia Sportage – Safety Hazard. Incident Date: April 18, 2026. Location: Parking lot. While pulling into a parking space at low speed, I brought the vehicle to a complete stop with my foot on the brake. Immediately after stopping, the vehicle suddenly and forcefully accelerated forward on its own without my foot on the accelerator. I was actively pressing the brake pedal, but the vehicle did not respond as expected and continued to accelerate. The acceleration was strong enough that the vehicle jumped over the parking bumper with both front tires and struck a fixed post. Even after impact with the post, the vehicle continued to push forward as if still accelerating, until it hit another barrier and finally came to a stop. At no time did I press the accelerator pedal. The vehicle’s behavior felt completely uncontrolled and unsafe. This incident could have resulted in serious injury or death if it had occurred in traffic or with pedestrians in front of the vehicle. The vehicle has been towed to KIA dealership and is pending inspection. I am reporting this as a serious safety defect. No injuries. Front-end damage after collision with post. This event was sudden, unexpected, and not driver-induced.

A month after buying my vehicle in February of 2024, while driving my vehicle the screen behind my steering wheel will black out and come back on and do a system check as if I had just turned my car on. It happens at all times of day, at all speeds. I kept a log of some of the incidences and there are no two that are the same. I have even been in park with the car on and it will happen. When you are driving with cruise control on and it does it the cruise control shuts off then comes back on after it has done the system check again. This is extremely dangerous while driving on the interstate and a line of cars around you. I have taken it to the dealership and they have worked with Kia to try to figure it out and still have not been able to. I am now going on almost two years of this happening without any resolution. Below I put the last time it happened but this happens ALL the time and is not one isolated incident. I have attached a log I kept for two months of the incidences.

Since day one of my purchase I noticed All warning light turned on and goes off while driving over an hour I thought it was normal as it’s my first Kia so continue to drive and it did same when ever I go on long drive and after 2 months it started vehicle to loose power and I always has to stop and restart the engine. Continued with same issue and all of a sudden it stopped on interstate and this time the car bogged out and engine shut off which was a dangerous situation for my whole family as cars behind would have hit us and cause multiple car collision I called my dealership to add this issue on my appointment for first service so it can be taken care of and I dropped off the car at dealership and after road test they confirmed that yes it has issue where multiple lights comes on and off so they don’t really know what’s causing the issue but will try to change the infotainment screen which they think is the issue might solve it so they kept my car for more than 90days and got my car back with scratches on dash and digital display bit shaky but according to milestones look like they tested if the issue been solved. ????
