2020 KIA OPTIMA Engine Problems

Car has been excessively consuming oil for the past year. Black smoke blowing out of exhaust pipe. Engine siezed up which almost caused an accident, had to veer off the road to keep from causing myself and the other party harm. Kia is stating no recall but there is tons of motors having this same issue. The actual motor in car is a 2019 model engine.inspected by Kia dealership with no help stating out of warranty even though this has been going on for over a year.

I purchased my car used in 2022. It had a metal clanking noise in the engine. I took it to KIA they said there was no recall open for them to check it. The sound is getting worse and the engine is now burning oil but KIA won’t do anything unless I pay them $1,200 to clean the heads and another $187 an hour to scope the engine. This has been a problem since I purchased the car and I am sure it has to do with the engine recall but they refuse to fix it or look at it. I have had regular oil changes and maintenance done at appropriate intervals.

I was driving in the freeway to my girlfriends house and suddenly my check engine light came on and started flashing, I got off the freeway as soon as I could and parked to check what was wrong and while driving to park I noticed I couldn’t accelerate past 2000 RPM and when shifting my car was skipping and it felt like gas wasn’t getting to the engine. I checked my oil levels and they were at normal levels, the battery was fine, and the car was turning on without a problem. I ran a diagnostics code and it came up with the P13-26 Code

Oil leaking at drain pan and won’t come out.

While traveling on the highway at the stated rate of speed between 65-75 mph, my vehicle experienced what I described as a downward surge causing the vehicle to suddenly lose speed immediately followed by a consistent blinking engine light. Fortunately, I was in the slow lane and there wasn't a vehicle behind me, or I could have been rear ended. I tried to accelerate; however, the engine acted as if it was choking. I backed off acceleration and allowed the engine to pick up speed on its own. Fortunately, I was almost home and stopped by the Auto Zone in my neighborhood and they attached the device that will generate the code. The code generated P1326 which points toward the knock sensor. KIA need to address this issue and be made to correct these dangerous issues before someone is in a major accident where they may find themselves in a...

June 29th I was driving home and car suddenly went into limp mode. Had this car less than 2 yrs. I'm the second owner so I don't have 100,000 engine warranty. Its at 91 000 miles. Gets maintained regularly. But the cart consumes a lot of oil and after I google and read all about P1326, i find out there is a campaign by kia fixing these engines. Unfortunately my make and model, even tho same engines didn't make the cut. From the list of complaints from people online seems to me that there will be more legal action taken. These are the same crappy engines. I will never nor let anybody I know by a Kia/Hayandai ever again, if I can help it.

Leased this Kia by force from rightway auto here in Indianapolis in. Had for about 1 1/2. First notice after filling up my tank gas was depleted within 3 days on driving 12 miles to and from work in town. Then oil start disappearing a week after oil changes. .around Jan 8,2024. Check engine light start flashing driving the highway to work. Speed jumped down to 45. Engine start shaking if I tried to go faster. Got a engine light scan says needs knock sensor. Had it replaced. 6 months later. Car did the same thing. Same code. Knock sensor. Had it re replaced. 3 hours later car did the same thing. Each time while driving the highway almost got me rear ended. On June 27,2024 took it to ray skillman dealership. Found out knock sensor needed to be replaced again, this time along with plugs n worse apparently knock...

Cat consumes excessive oil. Smokes.

Oil consumption is absurd. 5 quarts in 2k miles.

On April 19 of this year I was driving on the freeway and I noticed my car was losing power and my engine light came on and I quickly had to merge over to the emergency lane while my car was jerking back and fourth and making a knocking sound. I’ve only had the car for about 5 years and I took it to the dealership and explained to them that my oil would burn faster now and I think it was messing up my engine but they didn’t care. They said I need a new engine now and it’s going to cost me $6200 to fix and I’m still financing on this car.

Unknown all I know is my check engine light came on . And was told from O’Reillys that my knock sensor was bad. And I have warranty so I reached out to you guys but still haven’t got a call back

Engine is burning 1-2 quarts of oil per week. I work from home so it only get driven once or twice a week max. I’m still making payments on a car that is unsafe to drive, eating oil, and running potential for the engine to lock up due to it being the exact same engine with the exact same issues as what is in prior years but for some reason to 2020 was not included in the recall. I am a single mother of 4 and can’t afford to put thousands of dollars worth of work into this car, that’s why I bought newer for reliability and I can’t even confidently put my kids in this car and am stuck with it for another 4 years. Kia needs to address this!!

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 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...

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...

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...

The contact owns a 2020 Kia Optima. The contact stated that while her husband was driving at an undisclosed speed, the vehicle was shuddering. The contact's husband was able to drive to the residence. The vehicle was then towed to the dealer, where it was diagnosed with DTC Code: P0304 “Cylinder # 4 misfire). The contact was informed that the engine needed to be replaced. The dealer informed the contact that the warranty had expired. The vehicle was not repaired. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA Hotline. The failure mileage was approximately 123,000.

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 .

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

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.

Dealers claim pistons are bad and engine is stalking eating through 2 quart every thousand miles or less. Properly maintained and everything not sure why the pistons would be bad already, also replaced a pcv sensor to fix problem but did not change anything.

The contact owns a 2020 Kia Optima. The contact stated that while the vehicle was in for routine maintenance, it was discovered that the engine oil level was extremely low. The vehicle was taken to the local dealer who performed an oil consumption test. The cause of the failure was not yet determined. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 60,000.

The passagen side seat belt comes on and beeps and stays on sometimes and other times it dont Then the check engine one day started flashing on me lost of power wouldnt do no more then 60mph

Car burns through 3 quarts of oil per week with just normal usage. Confirmed there are no oil leaks.

2020 Kia Optima with 39,000 miles. Check engine light came on for knock sensor and put into limp mode. Before the check engine light came on I've been noticing a faint noise during acceleration from the engine. Waiting to hear back on the overall problem.

Vehicle was tampered before purchasing, transmission mounts broken, evap hose gas tank and engine.. car was claimed as a lemon vehicle, dealership sold me a vehicle that’s unsafe to operate. Dealership refuses to fix…

The Kia optima 2020 2.4 every 3000 to 4000 miles oil change is metal shavings in the old oil. The clicking noise stared it around the 10000 miles mark and now is getting worse with 60000 miles ,everytime I hit the gas and goes over 30 miles loose a lot of power and a clicking noise come out ,now is getting worse. Is a new car. Already change a ABS pump and I keep my oil change to the date. I m afraid the car is breaking . Help.

I was driving in the freeway nearby San Jose, CA with my family in the car. I was doing 67mph. It was high elevation curvy road. I experienced engine stalling. The car suddenly stop accelarating and speed drop to 35mph despite pressing on gas.

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.
