2023 Kia Sorento ELECTRICAL SYSTEM,ENGINE

While driving vehicle looses throttle power, goes into limb mode. Does not throw any codes. Turn the car off then back on and drives fine for a little bit. Has happened numerous times. Multiple trips to the dealership but since no codes pop up nothing can be fixed. Major safety issue!!!!

The contact owns a 2023 Kia Sorento. The contact stated that the engine START/STOP feature was malfunctioning. The contact stated that while at a complete stop, the engine START/STOP system caused the vehicle to restart, and then to stall, nearly causing a crash. The battery warning light was illuminated and the message "Shift to Park to Start Vehicle" was displayed. The contact stated that the failure had been recurring intermittently. The vehicle was taken to the dealer however, the failure could not be duplicated. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 1,200.

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.

Twice while driving on the highway the engine power went off and all the safety lights flash and I could not accelerate. I was able to pull Over in neutral and restart the engine. When taken in for inspection, no problems were found. It happened again in June after the 7500 mile inspection on May 9th. This issue is life threatening as it could easily cause a fatal crash if I was not in the right lane, on flat ground, with a shoulder. There was no warning light.

The contact owns a 2023 Kia Sorento. The contact stated while driving at various speeds, several unknown warning lights and messages flashed on the instrument panel. The contact was forced to pull over and restart the vehicle due to the failure. The failure was intermittent. The vehicle had been taken to the dealer on multiple occasions; however, the dealer was unable to determine the cause of the failure. The manufacturer was notified of the failure and a claim was filed. The vehicle was not repaired and remained in the possession of the dealer. The failure mileage was approximately 2,000.
