    After the rod bearing engine replacement was preformed. My engine light came on a few days after picking it up from dealer. I immediately reported it to the dealer that I need to bring it in mainly for smog check, and no response. 2 weeks later I told them about it again. No response. 3 weeks later began a fuel smell and I immediately reported that as the smell got stronger. No response. 3 days later the fuel smell was really bad and I was really worried about a fire. This time I called general manager and he never provided any advice or return call. 3 hours later the engine caught on fire. Car is totaled and I could of been seriously injured. I sent pictures and thanked them for their negligence. He finally gave me a phone number for consumer affairs. showed no remorse and claimed that the new engine they just put in has no warranty and they are not responsible. If they would of directed me to bring back in. Or bring it somewhere. Or tell me not to drive it. But completely ignored me. And had the nerve to let me know that was their 4th fire this week. Kia management needs to step it up. I was denied a loaner or rental. And they will try to get back to me by Friday. You must put a stop to this behavior asap!

    Vehicle suddenly cut off and lost power. Upon cutting back off check engine was blinking as well as oil light. Was left to sit over night as it wasn’t safe to drive home and would not restart. The following morning the car started but was hesitant driven less than 20 miles home which struggled to accelerate and check engine light was illuminated along with oil light coming on . Oil was in the car at the time. Parked in front of home additional oil added oil light then oil light cut off until ac is turned on . Car was turned on and sitting and a knocking noise began . Left to sit the next day then taken to jiffy lube where a reading came on the scanner that it was the crank shaft was then ordered to go to a repair shop where it was diagnosed the engine is blown and that oil was basically being burned even with a maintain of oil changes therefore this caused metal to metal contact . The engine is now seized up and the vehicle is sitting outside of home. Vehicle is unsafe to drive upon further research cars 2011-2019 with the same engine have caught fire or failed . Due to this there is now a class act suit theta ii with Kia .

    My vehicle has been smelling like fuel inside of the vehicle and cannot take it to a kia dealership due to them being backed up. There are no visible leaks inside or outside of the vehicle but it is unsafe to inhale fuel and every time i fill it up, the smell gets stronger.

    My car caught on fire while driving from somewhere near the engine. The fire was so severe that fire department nor my insurance company were able to determine cause of fire and I’d only had vehicle for 45 days, it was a single owner with no accidents and maintained its entire life up to that point. I am requesting someone to examine vehicle and tell me how this possibly happened.

    I took my car in for the air bag recall in 2018. When I picked up my car the air bag light was on. I called the Kia service line and they told me the light should go off on its on. So I drove home. I drove to work and back home and the light was still on. So I called the Kia service again and they told me to bring in the vehicle which I did. They checked and told me that they had no way of turning off the light. So I just drove home thinking everything was ok. Fast forward 2022, I had a seperate problem that forced me to take my car back to the kia service shop. They checked things in my car and I was shocked to learn that my air bag would not work in case I was in an accident. I told them this light has been on since after they did the air bag recall work but I did not feel supported here. the price tag to fix it is $1470.65. I feel that I am being treated wrong here because their initial work caused this light to turn on and they told me it was not related but now this vehicle check says it is a big concern if it is not fixed. I drive my three children to school in this vehicle. I am afraid for them and myself. I don't know what to do. This was part of the air bag recall and they caused this light to turn on and they need to fix it for me.

    The speedometer quits working, the car will not shift into gear after parked and turned off, all the dash lights come on. You have to hit the reset button on the gear shift to get the car to do anything.

    I was driving my 2012 dia optima approximately 55 mph and without warning the engine died killing power to steering and brakes.....tried starting it back up heard the fuel pump kick on good ground all the basics then I began to google possible issues and saw there were serious engine issues where the car either spews high pressure gas and potentially catches fire or bearing wear where the engine will shut off without warning.....I typed vin in said my vehicle was part of the theta II GDI engine recall so I called the 800 number where they told me that there were 2 recalls that needed to be done "before" the engine fails and that my vehicle had only had one of the two so I would have to pay to have it towed (315$) to local dealership to have diagnosed and tech line opened. I dropped it off on Saturday the 28th of may and was told due to holiday weekend it would be Tuesday the 2nd they would call well finally yesterday june 15th they finally called and the fella told us it wasn't covered and it would cost 8000$ for them to put an engine in or I could sell it to them for 300 or 400$. I called corporate immediately after speaking with ole dude the lady asked what the diagnostic came up with because my car is covered under lifetime warranty for the bearing issue in fact and doesn't matter about the fuel issue. She seems to think that he never even put on diagnostic machine she tried calling him 4 times from headquarters and was ignored each time. They never tried contacting me which was a registered owner or my wife who is now and even as far back as my little brother who I bought the car off of it was still registered in original owners and according to what I read they were supposed to actively seek out vehicle owners through registration etc because of danger and then in my opinion dude tried to hustle me knowing the car was actually covered telling me no and giving 400 then turn it in get new motor and make 10k....I did not smell fuel when I popped hood so I know
