2018 Kia Sportage Driver assistance Problems

My 2018 Kia Sportage (VIN [XXX] ) experienced complete engine failure due to low compression/internal combustion chamber failure. The vehicle lost power while driving on Sept 30, 2025, and had to be towed to [XXX] Kia in Dayton, OH. This same dealership previously performed an oil retention test in Aug 2024 which failed, identifying a defective engine. Kia was aware of the issue but declined to replace the engine at that time. The failure pattern matches Kia’s known engine defect. Kia Consumer Affairs (Case #25572677) has denied goodwill assistance despite this safety-related engine failure and prior diagnostic documentation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

UNKNOWN. A warning light on dash comes on. It stays on up to 20 minutes then goes out. There doesn't seem to be any trigger causing the problem. It does this everyday at ant speed.

With the cruise control set at highway speed (65pmh, etc) If you push the foot controlled parking brake it will not cancel the cruise control. The vehicle increases the acceleration to maximum and overrides the parking brake input. If using the parking brake in an emergency you would stomp on the parking (emergency brake) and not be able to slow down unless separately cancelling the cruise control.

ALL OF THE LIGHTS ON MY DASHBOARD COME ON AND WHEN THIS HAPPENS IT'S GENERALLY NIGHT TIME. I CAN'T DRIVE MY CAR WITH THE HEADLIGHTS ON BECAUSE IF I CUT THEM ON MY CAR WON'T MOVE AND MY REAR VIEW CAMERA WILL NOT WORK. THE FIRST TIME THIS HAPPENED IT WAS 05/18/2019. I WAS DRIVING IN THE EVENING HOURS TO PICK MY SON UP FROM WORK I NOTICED THAT THE CAR STARTED TO SLOW DOWN AS I HAD MY FOOT ON THE ACCELERATOR, I PULLED THE CAR TO THE SIDE BEFORE IT STOPPED AND TURNED EVERYTHING OFF. I WAITED A FEW MINUTES CUT IT BACK ON AND EVERY LIGHT ON THE DASHBOARD WAS ON. I COULDN'T MOVE MY CAR I CUT THE HEADLINE OFF AND IT PROCEEDED TO MOVE. HOWEVER AT THAT TIME OF NIGHT I NEED LIGHTS. THE NEXT MORNING I TOOK THE CAR TO BERWYN KIA IN BERWYN ILLINOIS AND WAS TOLD THAT A SOFTWARE UPDATE WAS NEEDED, TOOK 30 MINUTES AND I WAS GONE. A WEEK OR TWO LATER I WAS RIGHT BACK WITH EXACT SAME ISSUE AND WAS TOLD IT WAS A HARNESS PROBLEM AND HEY WOULD GET IT FIXED. MY CAR WAS HERE FOR A MONTH. I PICKED MY CAR UP AND 07/03/2019 IT HAPPENED AGAIN AND I HAVE VIDEO FOOTAGE FOR EACH INCIDENT. I CALLED KIA CUSTOMER SERVICE AND SPOKE WITH THEM AND I AM NOW BEING THE CAR BACK AGAIN ON 07/17/2019 BECAUSE ALL OF THE ISSUES HAVE HAPPENED AGAIN!!
