This car was equipped with the theta ll engine and I believe that-€™s what caused it because it was an electrical smoldering. The car has been signed over to the insurance company, it was totaled. If this had happened 30 minutes sooner, I would have been burned. Me and my daughter had luckily just got out of the car. No the problem has not been confirmed by a dealer. It has not been inspected by the manufacturer, but has been inspected by police and insurance. There was not any warning lamps or messages prior to the incident.

Car ran perfectly. No indications on the dash cluster until the check engine light started flashing and car went into limp mode. Got to safety off freeway to a gas station lot. Parked car. Took video of the car running while recording the dashboard. Pushed the gas while in park to hear Rod knock. It was 10pm. Had car towed home. 2 days later towed to dealer. Between time it broke down and I had towed to them. I found out about the knock sensor. I also joined a group on Facebook with hundreds of people getting screwed over. There I learned about class action and oil consumption issues. Not on any oil change was I made aware of low oil. I check my oil levels and have a high class mechanic change my oil. So first the dealer calls me and says. Technician states no oil in engine. I ask. Well why was there no oil light on? I said if there was. I-€™d had had my car checked. I said only thing in was flashing check engine light at the moment of failure. He advised. No the engine lights not on but oil light is. I emailed him my dash cluster video. He calls me and says. Oh you-€™re right. Sorry miscommunication with technician. I also sent picture of oil dipstick that showed there was oil filled to The top indicator. Advisors Response was basically a shrug. They asked for most recent 6 oil change receipts. I furnished 8. They said sludge in engine. I asked for pics. After 6 requests I received 2 pics that do not match up with pics I took of same part. So at this point per at least 200 people and myself. Kia and Hyundai are voiding warranties and not backing up their crappy engines. WE NEED HELP URGENTLY. I have not paid car payment since breakdown. I am $3700 in the hole paying for rental that I was told would be reimbursed once engine replacement was approved. Well they SUCK. Many more in my position or worse now. This is criminal and fraudulent

We own 2 2019 Kia optimas, one my 20yr old daughter drives. On her way to school she smelled a burning smell. On her way home at a dangerous intersection she smelled a strong burning smell & the car just stopped. I told her to get out of the car quickly, she had to climb to the right side as it was too unsafe to exit from the left. Thankfully she wasn-€™t on a 55 mile/hr road bc it just stopped abruptly & surely would have been hit as brake lights would not have warned. The car was towed to the dealership where it was purchased & under warranty on Friday 3/18/22. Saturday 3/19/22 I went to inquire what happened & was told by the service advisor that it started once, there was a burning smell coming from the engine & the engine was only running on 2 cylinders & stopped. He said they created a ticket, which I came to know that they were conferring with Kia engineers by Kia consumer affairs & I also created a case with. We did research & found a class action suit that was settled describing the exact problem that we experienced, however bc it was settled, Kia was never had to issue a broad recall, so if your 2019 optima experienced this very serious problem of engine failure & fires after 11/30/2021, they say Kia will be handling the cases on a rolling basis, however we just got the run around & the car remains there today 3/26/22 unfixed & the dealership is trying to say it-€™s just a fuel pump & if that was the case, they wouldn-€™t need 8 days waiting for Kia engineers to be fixed. In the settlement, Kia was also noted to be denying proper fixes for this serious issue with cars still under warranty. We were denied a rental car & they will not call us. This is my daughter-€™s life, please help us. The other 2019 Kia Optima that I drive was brought to the same dealership under warranty complaining of the engine sputtering & jumping, they did nothing & said it should be fine however it-€™s still doing it & my daughter is now driving this potentially dangerous car to school. This vehicle has been there since 03/18/22 & it-€™s 0

I purchased on my 2019 Kia Optima on 6/19. And since then off and on the car has experience intermittent starting issues. Now I have taken the car to two different dealers and neither one can find the problem. When pressing the stop/start button the car would hesitate to start no lights or codes are stored in the computer. I have contacted Kia about the issue all I was ever told was take it to the dealer and let them inspect it. The dealer would reset and update firmware. That would last for a minute but eventually the car would go back into the same thing of hesitating. The car has been into the dealership multiple times for the same issue Kia has opened case after case but no solution. The car is considered a lemon by state statues. Not one time has Kia offered to take the vehicle the only thing I'm told that if it happens again bring it back. I would spend more and miles taking the car to the dealership. There is also an issue with the wheel alignment the left rear wheel always need to be aligned I'm not sure why but when I take the car for an alignment that wheel is always out of specs.

The contact owns a 2019 Kia Optima. The contact stated that while driving at 45 mph and merging onto the highway, the vehicle stalled without warning. The contact pumped the accelerator pedal several times and the vehicle responded. The vehicle was not taken to be diagnosed nor repaired. Neither the dealer nor the manufacturer was notified of the failure. The approximate failure mileage was 74,800.

I bought my 2019 Optima brand new back in November. It is now June and I have had it back to the dealership 3 times for randomly not starting on me. I get the same answer every time. They don't know what it is, nothing comes up on the computer when they plug it in. They say, "if it happens again, call us and well take it in". buying this car brand new and my payments being that of a range rover, I am extremely upset. To top it off, the back windshield is slipping down. I am over this car and I will never buy another Kia again. But, my fight is not over, something will have to be done. It also hesitates at times, feels as though it is struggling to go. Also, two times while I was driving the car, the dash lit up with almost everything like, I was in a crash, the exclamation point, etc.
