2018 Kia Optima Hybrid Problems

The contact owns a 2018 Kia Optima Hybrid. The contact stated that while operating the vehicle, the message "Turn Engine Off Immediately" was displayed, and the vehicle decelerated to 35 MPH and stalled. The vehicle was towed to the local dealer who diagnosed that the engine was faulty and needed to be replaced. The engine was replaced but the failure reoccurred. The manufacturer was notified of the failure. The failure mileage was 100,000.

While driving down the road the car said it had a major voltage failure and was shutting down. I was in the middle of the street and thankfully was able to coast to the turn lane before the car came to a total stop. since the gas pedal didn't do anything. the car then said there was multiple failures and the hybrid system needed to be immediately shut down. The car then wouldn't start or move after that. about 20 mins later the car like dashboard and screen would turn on but the engine would not. when it turned back on there were even more warnings along with other failures like emergency braking and transmission and the hybrid communication. when the tow truck came and took it it would go into neutral to get on the truck but wouldn't even do that when we got it to the dealership it had to be manually taken out of park to get it off the truck. there were lots of warning lights but the oil, engine, and another light I not sure what it meant were always on even when the others would go away after a while.

I brought the vehicle into Kia service for the recall including a computer operating system upgrade. After the recall work was done the car driving at high highway speeds failed, and immediately slowed down, almost causing a rear collision. The computer system turned off the drive mechanism and I was left with only the electric motor to propel the car. The car barely limped off the highway. The car was brought to the Kia Dealer and no defect was found and the computer was reset. This problem occurred two more times, at highway speeds (70 mph) and Kia was contacted to find out why the problems occurred and how to fix it. To date, Kia has not responded to how to fix the problem and has ignored all phone calls and emails. The car has been in the shop for 3 months. The problem occurred only after Kia upgraded the software due to the recall. Additionally, the recall work was done. I do not know why the recall work was not reported.
