2019 Kia Stinger Powertrain & Transmission Problems

My 2019 Kia Stinger GT2 with approximately 25,000 miles has been out of service since February 12, 2026 for diagnosis and repair of a system issue. The vehicle has remained at the dealership for over two months. Multiple repair attempts have been made, including escalation to Kia corporate engineering. Despite these efforts, the issue has not been clearly diagnosed and no permanent repair has been completed. The vehicle is currently unusable, and the inability to identify the root cause raises concerns that the issue could result in unpredictable or recurring system behavior. Given the reliance on electronic and computer-controlled systems, there is concern about safe and reliable operation if the vehicle is returned without a confirmed fix. The manufacturer has not provided a clear resolution or timeline.

MY VEHICLE WAS STOPPED AT AN INTERSECTION COMING OFF INTERSTATE THIS EVENING AND MY CAR JUST JUST DOWN AS THE LIGHT TURNED GREEN. I TRIED TO START IT 3X AND 4TH TIME I OPENED THE DOOR AND SHUT IT AND THEN IT STARTED. 3 DAYS AGO I GOT A VOICE WARNING SOMETHING IS WRONG W THE ENGINE CONTROL SYSTEM. TOOK IT TO DEALERSHIP AND THEIR SYSTEM IS DOWN BUT SAID IT COULD BE BECAUSE FUEL WAS LOW AND DIRT COULD HAVE CAUSE THE WARNING. THEY CALLED SATURDAY TO CHECK ON ME AND IT WAS FINE UNTIL TODAY. I WILL HAVE IT TOWED TO DEALETSHIP. THIS HAPPENED BEFORE ABOUT SIX MONTHS AGO AND THEY CHANGED BATTERIES IN KEY FAUB AND HAS BEEN FINE TIL TODAY. OTHERS SHARING ON FORUM HAVE HAD SAME ISSUES. ONE HAD BODY CONTROL MODULE REPLACED FIRST TIME AND SECOND TIME THEY REPLACED WIRING HARNESS. I HAVE A FEELING THE AUTO STOP IS INVOLVED

ON FEB 18, 2020 THE CAR HAD A THROTTLE HESITATION AND CUT OFF IN TRAFFIC WHILE TURNING THROUGH AN INTERSECTION AND WHEN STARTED AGAIN HAD CHECK ENGINE LIGHT AND CAR WENT INTO LIMP HOME MODE. CAR HAD ERROR CODES P061B, P0172, P0175, P2180, P2178. KIA ADVISED TO NOT DRIVE THE CAR AND HAVE IT TOWED TO DEALER. I WAS TOLD THERE WAS A LOOSE WIRE CONNECTION AND DEALER SUPPOSEDLY FIXED IT. ON MARCH 23, 2020, CAR WAS RUNNING WITH ROUGH IDLE AND CHECK ENGINE LIGHT CAME ON PULLING CODES P0108 AND P0068. CAR WAS ABLE TO BE DRIVEN TO DEALER AND DEALER COULD NOT FIND THE ISSUE. ON SEPTEMBER 25, 2020, CAR HAD ROUGH IDLE AND CHECK ENGINE LIGHT AND PULLED CODE P0068. CAR WAS ABLE TO DRIVEN TO DEALER AND DEALER COULD NOT FIND THE ISSUE. DEALER SAID MAYBE IT WAS RELATED TO K&N AIR FILTERS SO AT THEIR ADVICE AND REPLACED THEM WITH STOCK AIR FILTERS. JANUARY 26, 2021, CAR HAD THROTTLE HESITATION ON THE HIGHWAY AND WHEN ON THE EXIT RAMP THE IDLE WAS JUMPING BETWEEN 1000 AND 1500 RPM. CHECK ENGINE LIGHT CAME ON AND CAR WENT INTO LIMP HOME MODE AND PULLING ERROR CODES P061B, P0172, P2178, P2180 WHICH WERE THE SAME CODES FROM FEBRUARY 18, 2020. CAR WAS TOWED TO DEALER JANUARY 27, 2020, AND FOR TWO DAYS THE DEALER HAS NOT BEEN ABLE TO FIND THE ISSUE. I DO NOT CONSIDER THIS CAR SAFE TO DRIVE. THERE'S AN ELECTRICAL ISSUE THAT CAN NOT BE FOUND AND NOT KNOWING IF CAR IS GOING TO STALL OR GO INTO LIMP HOME MODE IS A TERRIFYING WAY TO DRIVE.
