Type: Vehicle, Vehicle: 2023 KIA K5, Manufacturer: Kia America, Inc.

Sep 2025

While driving at about 70 MPH the right rear tire locked up temporarily causing loss of control of the vehicle. Luckily there were not other cars around as the car was in 3 lanes prior to coming to a complete stop. If this happened in traffic it could have caused a significant accident. There were no warning lamps on dash before or after the incident. After inspecting vehicle on side of road I could not see any issues. Drove about 15 yards and heard a grinding noise. Vehicle was towed to dealership. Dealership has inspected vehicle and advised it was caused by a failed awd coupler. The repair will be covered by warranty.

Transmission is itself in neutral while driving. Resulting in irratic RPMs, hesitating acceleration and rough transition to gears. Took care into dealership service department. They seemed that I would need a transmission replacement. Kia approved the request. Still waiting on transmission to be put in.

WHEN DRIVING MY CAR WILL SEND OFF ALL DASHBOARD LIGHTS, SOUNDS. LOSE ACCELERATION. PULL OVER, RMPS FLY UP AND WON. TURN CAR OFF AND TURN BACK ON TO REGAIN ACCELERATION. ENGINE LIGHT REMAINS ON. I KNOW THERE IS A RECALL FOR THIS FOR MY EXACT CAR TYPE, BUT THE RECALL DOES NOT SHOW UP UNDER MY VIN. AFTER A PHONE CALL WITH NHTSA, I WAS TOLD TO REPORT MY VEHICLE TO THE WEBSITE. MY SAFETY AND OTHERS IS AT RISK FOR OBVIOUS REASONS. THIS CAN EASILY CAUSE A CRASH. THIS HAPPENED ONCE AT 5K MILES, DEALERSHIP SUPPOSEDLY FIXED IT. BUT IT HAPPENED AGAIN THE OTHER DAY AT 19K MILES. THERE ARE NO WARNINGS PRIOR TO MY VEHICLE GOING INTO SAFE MODE.

My wife was driving down the highway with her cruise control set to 75. She noticed she was only doing 71 and pushed the gas pedal manually. The rpm's increased to between 4000-5000 but there was no acceleration with the car. The car then dropped to 68 mph and would not accelerate at all. After pulling over and turning the car off and then restarting it started working ok. This seems to match the transmission recall of the 2023 Kia K5 GT-Line but this car is not currently included in that recall. This recall should be investigated and possibly expanded.
