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. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
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.
While driving, the vehicle engine shut off while making a turn. Before the engine stalled, the engine began to sputter as I made the turn. I was stranded on the roadway as I could not restart the vehicle. For my safety, I stayed in the vehicle as there was no shoulder and many vehicles including dump trucks. Several attempts to restart the engine were unsuccessful - the engine would try to turn over and then stop. I contacted roadside assistance and the car was towed to the dealership. Diagnosed as a faulty fuel pump/bad connectors. Approximately 8950 miles. This is the second time the car stalled while driving.
While in use, the vehicle engine shut off while making a turn. Several attempts to restart the engine were unsuccessful - engine would try to turn over and then stop. Vehicle was pushed off the road and roadside assistance was contacted and car tower to the dealership. Diagnosed as a faulty fuel pump. <900 miles.
