2015 Kia Optima Problems, complaints & recalls

I was driving to work when all of the sudden I was pressing my gas, but I wasn't accelerating. I noticed my brakes and steering wheel were hard to push and turn. My car stopped in the middle of the road. I turned off my car and tried to turn the ignition and all I got was a single click. My engine, battery and oil lights were now on. They were not before. After 25 minutes in the middle of the road a sheriff came and pushed me to the side. When I put my car in neutral it was hard to steer and my brakes were hard to...

There is a known issue with this vehicle and the fix by KIA is not safe nor fair to the consumer. Kia's knock sensor recall centers on the Knock Sensor Detection System (KSDS) software update for Theta II GDI engines. The update listens for rod bearing wear, triggers a check engine light and limp mode via Code P1326, and extends the engine warranty up to a lifetime or 15 years/150,000 miles.

My 2015 KIA optima experienced a catastrophic engine fire while I was driving. There was no warning, I just heard a boom in the engine bay the breaks stopped working and all electrical cut out. As I'm coasting, because I'm unable to stop, flames started to come in through under the dash. I couldn't turn the car off, nor put it in park so the doors stayed locked. The driver window was opened just enough for me to grab the top and break it, allowing me to crawl out. The car coasted itself to the shoulder then blew up (I had a full tank of gas.). All this happened in the manner of 30 to 35 seconds. It's important to note that KIA just replaced the engine 2 months prior to this incident.

The dealer had not yet provided a cause for the oil leak. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 123,000.

The engine in my vehicle failed while putting the car into reverse to back into my garage. I thank God I wasn't on the road when this happened. I took the car into a mechanic who confirmed that the engine was locked and that the car was very low on oil(even though I had my oil changed by him a few months prior). There was an undetected oil leak that led to the engine failure. The warning indicators didn't appear on my dash until after my engine failed.

My girlfriend was driving on interstate 95 to pick me up from the metro. The engine suddenly cut off in a manner that appears to have melted the wiring harness of the vehicle, risking fire. She was able to safely get to the side of the road and call a tow. After taking it to a local repair shop, they diagnosed the issue as related to the KSDS recall. We had it towed to the dealership that has also confirmed it is related to the recall. The engine is completely seized following this incident and it's worth noting that Kia is completely denying the engine repair claim as the KSDS update was not installed prior.

I was driving on the freeway and a system warning came up "check hybrid system" and the car went limp. Thankfully I was able to get off safely from the momentum this time, but it has stopped in the middle of the street before. This is the second time it's shut down this year. I took it in last year for the same problem. I took it to the Kia dealership and they stated there's nothing no wrong with it.
