2024 Kia Sportage: multiple warning lights

Filed Oct 21, 2026 · Driver assistance, Electrical · FL

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.

On Tuesday, July 14th I started my vehicle around 6:30 am and started to drive. Once I was driving, I had multiple warning lights on my dash showing and my power steering failed on me. I stopped the vehicle, put it in park and turned it off. I restarted the car and still had the various warning lights and no power steering. The car was driving fine with no warning lights at 4:50 am that morning and again at 6:15 am that morning. I managed to drive the 2 miles home at a low rate of speed with no power steering since there were not many cars out. I called the Kia dealership and contacted a tow truck to take the vehicle in. The tow truck driver saw the warning lights as well and had to maneuver the car with no power steering onto his truck. Once Kia did the initial inspection, they said there were no warning lights and the power steering worked. They were going to conduct a more thorough inspection on Friday to see what the issue was. I called end of day Friday and was told they would need more time to inspect since they could not find any issues with the car. The know the warning light had shown up but if they could not recreate the issue then the car would not be looked at further. This is the 3rd issue with this vehicle that the dealer could not recreate. I've had the vehicle stall on me at a light when I was stopped or at a stop sign as well as not accelerate when I was at a high rate of speed in an emergency situation. This issue puts me and my family at risk if I were to be driving during a busy period or on a highway. My car is only 2 years old and has under 32k miles, I drive it frequently to visit family 4 hours away. I am to pick up my car from the Kia dealer and I am scared to drive this car. I feel it's a deathtrap and an accident waiting to happen. Kia said I can always trade it in for a new car, but no thank you.

On December 24, 2025, while driving in traffic, my Kia Sportage experienced severe lurching, bucking, and jerking, causing the engine to shut down. All dashboard warning lights illuminated, including a message prompting me to "turn engine back on." The vehicle would not restart, necessitating a tow to Horne Kia. After several days of diagnostics, it was determined that a blown ignition fuse and a bad fuel pump relay were the issues, along with a battery replacement. However, just 19 days later, while attempting to merge onto the freeway, the vehicle again bucked violently, and the engine shut down with all warning lights flashing. The police had to assist in moving my vehicle out of traffic, and it was towed to Courtesy Kia in Mesa, AZ. Once again, no error codes were found. After further diagnostics, it was discovered that the same ignition fuse had blown and that the catalytic converter had "shattered." The catalytic converter was replaced. Upon picking up the vehicle from the dealership, and driving less then 5 miles on freeway, the vehicle was bucking and hard shifting once again resulting in a third tow to dealership just 48 hours later after the previous service. The dealership ran several diagnostics under Kia's tech line, which revealed that the engine pistons are slipping and not functioning properly, resulting in loss of compression. Per Kia's tech line, a new engine long block was ordered and replaced.

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. ????
