ELECTRICAL SYSTEM

I bought my car brand new in July of 2020. In Spetember of 2023 roughly around 60,000 miles the engine started consuming large amounts of oil. The dealership put me through the so-called warranty process 3x over a years' time. They refused to file warranty paperwork within the year I was going through the process. I have documentation clearly showing the engine burning 2 qtrs. every 1000 miles. I still have a car that I am paying on that needs a new engine that should have been replaced under warranty, but KIA failed to honor the warranty. I have been left stranded on the side of the road multiple times with my 3 children needing oil. Not to mention the car will lock by itself with it running and no one in the car. The screen where the radio is will just go blank.

I was driving down the interstate and all of a sudden the blinking lights of the check engine light came on and automatically I went from 75 mph down to 63 mph and when I looked up what it was, it was the knock detection system of the 2020 Kia Optima. I could not accelerate beyond 63 mph and I fear that the engine might stall on me so I went to O’Reillys and have them check it and it says it’s the P1326 Code

Hi, thank you for taking the time to look over my complaint. On Saturday march 22 while driving down the highway going about 75 mph, my car died. The check engine light was flashing and so was the oil light. I pulled over to the shoulder and when I tried cranking the car it sounded like a rumming noise and the car would not stay on. I had the vehicle towed to Texas Star Auto Shop. On monday march 24th i spoke with the mechanic and he said there is an internal engine problem . Since I am a 2nd owner and the car has 105,736 miles kia will not honor their extended warranty and I am left to pay out of pocket for repairs est cost 10,000+. I am now without a reliable transportation. This has left me annoyed and unhappy with the assistance from Kia.

I got a CEL (code P1326), three different times. Each time has been after a hard rain or a car wash. I have had to pay to have the knock sensor replaced each time, twice by a mechanic and once by a Kia dealership. There’s a recall for this issue on model years older than my 2020. I was told that Kia is aware but that there aren’t enough people having the issue to warrant them to investigate.

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.

April 30, 2023 my 2020 Kia Optima was stolen. The thief or thieves broke my backside passenger window to get inside. Once inside they started my car using a USB cord/ charger block. I purchased the car in Feb 2023. I wasn't aware of made aware the car's antitheft software needed to be upgraded which would've deterred or made it difficult for thieves to steal it. I wasn't notified by the dealership nor Kia about this needed upgrade. My insurance has denied my claim and I'm stuck paying for damages well over $4000. What can I do to prevent my car from being stolen again should I decided to keep it? I've reached out to the dealership where I purchased the car and Kia neither of them were concerned nor had answers

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/
