Misfire-?" oil on the spark plug caused misfire. check engine light came on. OBDII scanner show a P0302 trouble code. Eventually the engine misfired enough and lead to a backfire. This also led to Decreased Fuel Mileage, Catalytic Converter Damage, and Blue Exhaust Smoke.
Rear passenger window failed in June 2021 and cost $700 to fix, not under warranty per dealer. Replaced the window regulator unfortunately, I did not ask for the old part. One week later the rear window on the driver side failed in the same manner. Motor can be heard running and window drops down on it's own. My first fear was I was ripped off and dealer only switched the two parts because what are the chances? Having just spent $700 I did not return immediately but within 2-weeks, before making the appointment the passenger front window breaks! So at that point I start thinking a there must be a recall and start checking. I don't learn the cause of the issue until last month, Sept when the final window gave up as well. Not having the driver door window in FL where I drive on bridges is a hazard. I learned that a "plastic on plastic gear mechanism" fails over time. I am single and rarely have anyone in the rear seats so those gears crumbled from lack of use! KIA changed the design in 2018 due to failures but is failing to take care of earlier models costing owners thousands in repairs. I am the original owner, the car was 5-years old Feb 2021 and the car is garaged at work and home. These should be recalled no one should have to pay thousands in repairs when clearly this is defective and dangerous. All of the windows broke while the car was driving down the road. I live in Florida and this happened during storm season. Very luckily for the interior it wasn't raining as the windows were in the down position when they would not return to closed. I drive over Tampa Bay every day for work so not having working windows is dangerous. Someone should hold KIA accountable they know they are defective. I heard from a Hyundai owner they have the same problem, no surprise KIA owns Hyundai! I bet they changed that design too! My car is garaged work & home so likely helped mine from crumbling under warranty. Please recall window regulators!
Here in Wisconsin Kias are being stolen at an alarming rate. It-??s the most stolen car. It is being stated that this is due to how the cars were made and that Kia knew this but didn-??t disclose it. My car was stolen at work, along with other coworkers. This is beyond insane. How many more cars have to be taken due to manufactures negligence for something to be done.
I'm about to replace my THIRD window accuator on this car. The first one that failed was the rear passenger side at 54000 miles. The window was rarely if ever used, failed any way. The second failed at 60,000 miles.. driver side rear. Like the first, rarely used window. Now the third has failed at 66,000 miles. Cost to replace, over $300 because a $5 sprocket fails. Windows failing is definitely a safety issue.
While driving at night with the "auto" function for the headlights on they turn off at random. This has happened numerous times during the past year. Very dangerous on dark roads. Dealer could not replicate situation to repair. No warning lights appeared.

All 4 of my windows have stoped working and fall down while driving it started pouring down my driver window fell down and I almost wrecked I see a lot of people having the same issue
Having trouble with my driverside window it let's down but will not let back up i called kia and they want over $200 to diagnose it plus labor to fix it from what I have been reading online alot of people are having the same issue
All four of my car windows fall down unexpectedly due a defect in the window regulator part, and window motor. The windows do not respond to door controls and I've now had to spend approx. $3500. and many trips to the dealer repair shop to get these windows fixed. I live in Florida, and when a window opens unexpectedly in the middle of a severe rain storm and cannot be closed, this is a safety hazard. I've had to pull over when there is very limited visibility on the road, and try, usually unsuccessfully, to close the window. The glass windows are fairly heavy and my attempts to tape them shut do not work. I've contacted KIA consumer affairs and have filed a complaint with the Better Business Bureau, but so far KIA has done nothing and has not responded to the BBB (according to the last BBB email I received). The 4th window is being fixed today at the dealer, and another window is getting re-repaired, I don't know if any of the repairs will last, as every few months another window breaks.
The cars headlights turn off while driving under normal conditions. This has happened at least four times in a one month period. This is extremely dangerous as some areas are not well lit or an oncoming car may not see us. I have looked online and I see that this very same issue is occurring with this make and model dating back 6 or more months. It makes no sense that the bulbs would be defective since all lights go off and come back on randomly.
Three of the window regulators failed at the same time and the forth two weeks later. I had them repaired for a almost $ 2000 since the the vehicle has 62K miles and the warranty was good till 60K miles.
I started having problems with the oil disappearing not long after I got the new car Kia Optima year about February 2017 I keep pouring everyday more and more oil as I drive but it disappears. On or about August 28,2020, I received an email for a Kia engine class action settlement federal court that advises suffer from a defect that can cause engine seizure, stalling engine failure and fire etc. And that the engine can be dangerous Kia have been found liable for these claims. They said they gave me extra warranty but if it catches on fire or explodes then they would not help me and by then it is too late!! I told them that I am scared since I am a girl and keep adding oil and you never know what the engine machine malfunction can do. I could check the oil before going some where but you never know when the oil will all of a sudden disappear completely it is unpredictable. I have called Kia manufacture phone at 1-855-951-0807 and they are giving me the round around I am afraid to drive the car that one day it may do something and catch on fire. Please I would appreciate another car that will not catch on fire and be dangerous. See attached Kia engine settlement class action
I was just getting on to the highway and my sunroof exploded! it took me a second to realize thats what had happened it sounded like a very loud pop or gun shot almost I pulled over and seen my entire sunroof had exploded
My oil pressure light continues to turn on and off even after replaced parts! burning at least 2 quarts of oil per week! brake lights stop working if headlights are on! had to start using super to eliminate a rattle while accelerating uphill! engine shakes!!
The cluster started blinking out while driving then eventually goes out completely. At the start of the problem it would go out at times then pop back on for about two weeks.
The windows fall on their own and not operative while driving. It has happened to me twice so far and took the car to dealer. I am trying not to lower my windows at all for now. It is serious when it rains & water gets inside the car, I live in Florida and it rains a lot. Any solution ?
Since I bought 2016 Kia Optima ex, there has being windows problem on this model. Either window regulator or module panel or some thing else cause windows to drop down while your driving, or malfunction does not operate at all. At least 4 times I took to dealer to fix it, but in short period of time happens again, it is not one window happens to all of them. I am sick & tired of going to dealer to waste my time. It is serious problem with Kia and should redesign the operating window system.
