I had a recall on my engine back into 2018. They replaced my engine due the engine block being defective. Check engine light came before it stalled out. Now currently the vehicle is undrivable due to the head gasket blowing out on same engine that was replaced. They're telling me there's warranty on the engine they can't fix it.

Engine, Aug 11, 2022, fire
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 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 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

My engine seized up while driving with no warning or prior issues. My safety was put at risk because this happen while I was driving down a public road and could have gotten into an accident due to the cars malfunction. Kia has inspected the car but has refused to reimburse me for their engine failure although they had recall campaign for my model vehicle and other models of Kia vehicles. The only warning I was given was right before the engine failed the car said "hybrid system failure, do not drive"

I had went out of town and when driving back home the car start stalling and I pulled over to the side of the road. I tried to start it again but it wouldn’t start. After waiting on the side of the road for two hours I got the car pulled to a car shop. After they checked it the man told me that my motor was gone and I would have to get another one. I had called the Kia place about the recalls 3 weeks earlier and I haven’t heard back from them.

Engine replaced under the recall campaign after failure and have had issues since with the car wanting to start. Turns over several times before finally getting it to start. Fuel pump and fuel line replaced out of pocket as well as a sensor out of pocket and still having the same issues intermittently then today while driving approximately 35 to 40 MPH the car just shuts off in the middle of the highway in morning traffic and almost caused an accident, without warning. Still took several times to crank before car finally restarted and made it maybe 4 miles before shutting off again while driving without warning and then smelled as if something was burning. Car has had scheduled maintenance as advised by KIA for warranty on motor but if something is not done about all of these same complaints then someone is going to get killed. Very unsafe!

My engine failed. Dick Withams here in Waterloo, IA was paid by Kia to replace engine for free due to my warranty. Dick Withams rushed the process and allowed me back on the road with no coolant plug( which was detected immediately) I returned the car and Dick Withams attached a plug so my coolant wouldn't spill over on the ground. Every time I pressed my brakes THERE WAS A HORRIBLE SOUND LIKE MY DRIVE AXIAL WAS NOT PUT TOGETHER WHEN Putting the engine back. Kia is allowing Mechanics to fix these recalls of MAJOR SAFETY ISSUES FOR myself and my family. I then returned vehicle to Cedar Falls, IA Dick Withams to fix issue Friday morning. They have yet to communicate anything with me. Now I'm just without a vehicle even though it's covered under warranty. It should be against the law for the car dealership to return a recalled engine without driving the car to see if they rushed the service and failed to put vehicle back together CORRECTLY.

I was driving on the highway and suddenly lost acceleration, the check engine light began flashing. The car went into limp mode. I got it to an auto parts store and had them put it on the scanner. It is showing code P1326. I have it scheduled to be assessed at Kia. Research on this code with the Kia says, it could need a system update, knock sensor replaced, or the engine replaced. Kia does have a recall out for this issue but my car doesn’t currently fall under the recall. My car has always been mechanically maintained at appropriate intervals by Kia. This is a problem.

My car lost power going 70mph and the engine light came on. I had it scanned and the code was P1326. Now my car will not move. This was a reported recall on Kia Optima from years 2011-2014. My car is a 2012 Kia Optima. I called dealership and they said my VIN is not under this recall but I am having the same exact problem as the recall reported in 2018.
