I need an immobilizer installed on my car so I will be able to get insurance. Please recall these vehicles. This problem is because something wasn't installed on the car that it needs. PLEASE help us.

I purchased my 2020 kia optima 8/2022. On 10/21/23 I was on the freeway and the engine light started flashing, car made a knocking sound, went limp, speed dropped from 75 to 32 quickly while I was changing lanes, and Would not go over 32 mph. I made it home and started researching online and found out about the recalls. My car is not one since it's a 2020. I removed the car from my garage and parked it at end of my driveway and it's still sitting there as of today 11/13/23. I ordered a diagnostic reader and it stated code 1326 for engine. My car has done same things as the other recalled cars, same code, and same 2.4L Theta ll engine. I called Kia Corporate office on 11/13 (case #15978041) they stated my car is not one of the recalled cars, my warranty expired at 60k, and everything will have to be paid out of my pocket! I asked to speak to a supervisor and was given their voicemail. I called Kia here in Conway, Ark and they stated to bring car in for them to test it. Towing and testing would be at my expense. My insurance might cover towing and since I have extended warranty then they will need that information. I am not involving my insurance since alot of companies will not cover my vehicle due to the recent theft issue defect. They could drop my car to avoid possible liabilities. I should not have to involve my extended warranty since this is a Kia problem and I do not have money for a deductible for new engine. They knowingly put those same raggedy engines in the 2020 kia's, settled the recall case and now expect the consumer to come out of pocket for their fraud. Kia needs to come tow this car, provide me a rental, and replace the engine. They need to pay my car note and insurance for the months its not driveable, but thats legal issue I will address

I was told by me dealership recently that the Kia Optima is not designed for high mileage. It-??s been consuming oil and my dealership was aware of the issue. Yesterday smoke came out from under the hood and the engine and front half of the car was engulfed in flames.

The vehicle is incredibly easy to steal. A simple flat head screw driver in the hands of a child will steal this vehicle. My car was stolen from Daytona Beach Florida on July 8 2022 by 2 14 year and one 15 year old kids. No key, no fob needed, who knew it'd be so easy to steal? They learned it on TikTok. This is a problem nation wide and social media seems to spread the issue even further. I provided a link to one of many news stories regarding this problem below. https://www.usatoday.com/story/money/cars/2022/06/30/police-rise-car-thefts-kia-hyundai/7776099001/
