What 107 owners told NHTSA about the 2023 Kia Sorento Plug-in Hybrid

Was driving on Dallas North Toll way when my vehicle lost acceleration. Had to pull over and engine started smoking and lit a flame under the hood. Car is now at Clay Cooley Kia in Irving, TX. Car has been there for over two weeks and I still have no answers or information regarding the plan to fix it. Major dealership delay and all they keep saying is “Waiting on a Kia Engineer to come out but we don't have a date.”

The vehicle was purchased new. From day one, there were issues. When it was delivered from the factory, it was discovered to be partly unpainted. This raised quality concerns. So far, the most serious has been that the motor blower failed at approximately 29,700 miles. This resulted in the vehicle filling with noxious fumes. It then had to be abandoned on the side of the highway. This led to a fire dispatch and later urgent care visits. Prior to towing, it was discovered that the AC was not working and the engine coolant reservoir was at ~ 1/4 of the minimum line. Ultimately, the vehicle was towed to King KIA. They held the vehicle for 2 weeks. They drove the vehicle 16 miles. However, they did not diagnose the problem. The only action that they took was to refill the engine coolant reservoir. Prior to pick-up, we notified the KIA Customer Service Escalation Case Manager in writing that the vehicle had not been fixed and continued to represent a safety risk to our family. They took no further action. After pick-up, the vehicle was driven approximately 35 miles before the smoke started to fill the engine cabin. It was taken to two independent mechanics along the side of the highway. One was Vienna Auto Care and the other was Jiffy Lube Auto Care. Both identified that the motor blower resistor had likely failed. The JLAC manager also identified white material on the engine manifold believed to be engine coolant. All was documented in writing. The vehicle was towed back to King KIA. Prior to towing, the JLAC manager told us that melted motor blower casing was highly toxic. (Later, the KIA Case Manager informed us that he would admit that our family was put at risk by being told to pick-up the unfixed vehicle.) He also told us that if the motor blower failed then it likely was not an isolated case. This time, the motor blower failure was reproduced. However, the engine coolant issue has yet to be resolved. We are now being instructed to pick-up the car again.

I was driving down the highway on cruise control going 67 on a 65. The car started revving up and then proceeded to go faster. I turned off the cruise control but its continued to speed up. I stomped on the brake 4 or 5 times with no effect. I rammed into the back of a bus at 110 mph.
