This is my 3rd or 4th complaint on here with NO RESPONSE, HELP, OR ACKNOWLEDGEMENT! My 2020 finally got engine put in and car does not drive the same. Steering wheel acts weird, the engine has a sound, the anti collision lights went off twice, but could be due to weather. Kia told me that it's my responsibility since my yr is not on recall. I'm surrendering this car asap to give me piece of mind before another engine is due. I met several people at kia that are on their 2nd and 3rd engine and the mechanics told me they know I will be back for another engine! This is wrong and now I'm out of alot of money and surrendering this will add more negative factors. I have my receipts but im not posting publicly

I was driving my car and all of sudden it lost power. It would not go over 25-30 miles an hour. Then a loud, banging or knocking sound started. It has not been driven now for almost a year because of the knocking sound and no power. I-??m paying for a car that does not work and to no fault of mine. It seems to match the other recall complaints but mine isn-??t covered? This seems to be really unfair. If it is having the exact same issues as the year before mine it would seem to be the problem was never fixed. I will never buy another Kia due to this issue. It is such a huge safety concern and it seems like until someone is injured or worse then they might do something about it. They should be proactive on issues that seem to be going on with the same vehicle when it-??s the exact issue that is going on with the year/s prior to my car.

The contact owns a 2020 Kia Optima. The contact stated while driving 30 MPH, the vehicle went into LIMP Mode. There was no warning light illuminated. The vehicle was taken to an independent mechanic, who diagnosed that the engine consumed an excessive amount of oil and determined that the engine needed to be replaced. The vehicle was then taken to the dealer, where it was diagnosed that the transmission fluid, knock sensor, and spark plugs needed to be replaced, and a complete fuel system cleaning was needed. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 80,000.

My 2020 Kia Optima had engine failure and engine is being replaced now. I've had this car for 1yr/84k miles. It went limp on the freeway 2 mos ago and I could've caused an accident when it shut down. Would not go over 30 mps, engine light kept blinking and had knocking sound. Diagnostic code as the other recalls, Engine is same for the other recalls 2.4 Theta, oil was black and almost empty & just had oil changeI called kia corporate and they told me that they are not covering it since its not a recall. I have extended warranty but CNA National Warranty will only approve a used engine and a new one I would have to pay $3,000! I have made 2 car payments for a car that is immobile, $200+ for deductible, and $600+ for car service, this is not right at all. How can I get Kia to correct this. I do not want this car or any other kia! I cannot afford xmas this year all because I chose the wrong car maker!!

Oil plug fall out at highway speeds, engine failure. Engine stalled while driving, got vehicle to side of road, called tow truck after attempting to restart. When tow truck driver pulled vehicle onto the flatbed a massive amount of oil came out. After driver towed vehicle home he looked for a hole in the block found where plug had fallen out and advised us to look in the skid plate to see if oil plug was there, if we were lucky we could put it back in, fill with oil and restart. That is when it became obvious that the oil came from drain plug site and oil plug was found. Put plug back in, filled with oil and let the vehicle sit for a while before attempting to restart. Engine would not crank. Had vehicle towed to KIA service center by neighbor and dropped off where it was"lost" for two weeks. After they "found" my vehicle they scheduled a time to look at it. They called needing permission to put in a new starter and told us if they installed the started and the engine failed the test, engine repair would be covered under "this campaign". They put in the starter, ran an engine test and confirmed a new engine was needed. They called later that day, said it was not covered under warranty or campaign. I could not afford the engine replacement so had it towed back home by neighbor after paying for the starter. Car is at home parked and has not been touched since getting it back here. Plug fall out was 4,000 miles after last oil change. Vehicle went into limp mode one time, did need a boost a few times and the day off plug fall out my son was on his way home from work, headed to auto parts store to have them check battery, starter and alternator.

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

My engine is failing as of right now. It has yet to completely fail, but I was told by KIA today that it-??s failing and they don-??t know how long it has left. I just thought I would try and get a re call on it to get it fixed instead of putting myself or others at danger if/when the engine does fail.

- Nashville, TN, USA

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.

My engine needs to be replaced

- Phenix City, AL, USA

On July 4th 2023, I was driving with my son in car, when unexpectedly the check engine light came on and car lost power. We were on a highway with a 65mph speed limit. I was able to pull over to side of road. Car did Start back up, however was missing and misfiring. Shaking especially under acceleration. My engine has been consuming oil for many thousands of miles, it is documented; however only an oil consumption test was performed. Hyuandai and Kia has serious engine issues and they know it. This could've been worse. Luckily I still had some brake pressure to get off the road. With this stalling on the highway, it is very dangerous.

Owner's manual states the 1.6Turbo requires 4.75 qrts of oil with filter change. The car reads full after adding 4 qrts. Still reading full after double checking after 250 miles..Owner's manual typo". Incorrect dipstick during final assembly?.Following the manual could lead to overfilling/foaming issues and thus engine failure/safety issues. Perhaps a TSB needs to be done" Note: I used a Fram filter. Slightly smaller dimensions than original but in no way accounting for 3/4 qrts.
