2024 Kia Sportage

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.
