When headlight switch is set to automatically come on, the light will sometimes randomly turn off. No warning or indicator on the dash appears showing that they are off. Technicians are unable to reproduce the issue in the shop. Have recommended replacing the entire headlight switch on the turn signal stick.

Excessive oil consumption. Dealer says it is normal to burn a quart every thousand miles. At that rate I would have no oil left before my next oil change. That is not normal and could cause overheating and engine lock up. The car only has 45,000 miles.

I got out of my car to talk to someone and my car was running With my purse and phone in the car and the trunk open.i was meeting someone to buy a vacuume from Facebook marketplace. I decided to put the vacuum in the back seat instead so closed the trunk. When I went to open the door all the doors were locked. I was locked out in the rain for an hour. The person I bought the vacuum from called kia and they sent someone out to unlock my car. Several people have said the car is supposed to recognize that the key is inside the car and not lock it. And that this is an issue. I do know it has only started doing this recently because I live 8n the country and never lock my car in my garage. And recently I have noticed it is licking itself now every time I get out. So I have been leaving the windows down at home but it was raining today when I got out and I didn't think about or remember that it is locking itself .... Also I have never gotten out of the car to get something with it running and the windows closed since this issue came up.

FIRST INCIDENT OCCURED WHEN I WAS DRIVING TO WORK. THE ENGINE MADE A NOISE AND LOSS POWER WHICH ALMOST RESULTED IN A CRASH. I CONTACTED KIA, THEY EXPLAIN TO ME THAT A KNOCK SENSOR NEED TO BE INSTALLED AND SOFTWARE NEEDED TO BE UPDATED. THEY INSTALLED IT AND RETURN THE CAR TO ME. NOW AGAIN WHILE I AM ON THE HIGHWAY I HEAR A LOUD KNOCK, LIGHTS FLASHING IN THE CAR AND THE CAR HAS LOSS POWER. I ROLLED OFF THE EXIT PULL OVER AND CALLED A TOW TRUCK. WHILE WAITING I CHECK THE OIL IN THE CAR THINKING MAYBE THE ENGINE IS LOCKING UP. THERE IS NO OIL IN THE CAR, WHICH IS STRANGE BECAUSE TWO MONTHS PRIOR KIA JUST DID AN OIL CHANGE. I HAVE DOCUMENTS TO PROVE EVERYTHING. KIA HAS BEEN THE ONLY DEALERSHIP THAT SERVICE THE CAR. THEY NOW BEEN IN POSSESSION OF MY VEHICLE FOR FOUR MONTHS NOW AND NOTHING HAS BEEN DONE. I CONTACTED COOPERATE AND THEY HAVE FAILED TO GETTING BACK TO ME AFTER NUMEROUS ATTEMPTS TO GET ANSWERS. PLEASE SOMEONE HELP ME.

Hello, My Kia was stolen lastnight. The criminals apparently the “KIA BOYS” took my car, it wasn’t until after I spoke with my daughter she expressed to me that she saw a video on social media about Kia’s and another car, being stolen excessively. So after doing my research I was sent to this page to share my story. I am sure Kia is aware of the situation, so much so to where they are/have made a change in their 2022 model. But those of use who have a Kia model that is not a 2022, we are screwed. I make monthly payments on a vehicle engineered by adults, but what I’ve just found out is the criminals are mainly middle school age children who takes the cars for a joy ride. It is hard to process this oversight by Kia, I love my car, I’ve had 2 Kias. But this will be my last. Especially if they (Kia) doesn’t own this oversight. To have my car stolen hurts, I didn’t leave the key in, nor the door unlocked. I parked my car, activated my alarm, only to wake up and my car gone. I see there is a lawsuit in a state (I forgot the state) against Kia. I hope and pray the state of Georgia can start one as well. My car wasn’t the only Kia, taken lastnight. There were 3-4 others taken from this complex.

Didn’t have any transportation for over two months and car hasn’t moved since the day I dropped it off. I’m really getting impatient, as I am making monthly payments on a car that I can’t even use.

Engine overhead and stopped working in addition to it consuming massive amounts of oil without physically putting oil in. I've went to 2 dealerships who refuse to provide me with a new engine even though I'm covered under the engine extension warranty due to me having the knock sensor update done. I am now involving my attorney and will go to the news channels to inform how kia manufacturer has become a disgrace with not providing quality engines in their vehicles and don't want to be responsible for it. there's already a settlement going on for kia optimas and other cars they've made because of faulty engines. They can better believe I'm coming for them next with a lawsuit.

The headlights on my 2018 Kia Optima have been turning off and on randomly by themselves while in motion. Each time it's happened has been in different areas at different times of the night. The headlight switch is kept in the auto position most of the time. When the headlights turn off, the screen in the dash for the headlight function switches from auto to off by itself. Sometimes if the turn signal switch is jiggled the lights will come back on. Other times the headlight switch, located on the end of the turn signal switch, has to be turned to the on position to get the lights to turn on. The car has been in for service but each time the technician is unable to reproduce the fault. It is occurring more frequently and becoming a safety issue.

When driving with headlights set to Auto the headlights turn off whenever the blinker is used. I've found many complaints however my vehicle has not been inspected. This poses a hazard of driving at night with no headlights, then having to fiddle with the switch to turn them back on.

I purchased my Kia optima brand new I believe it had 7 miles on it when I purchased it, shortly after it was purchased it started having a problem with the transmission, I would go to takeoff and it was lunch and jerk pretty hard to where it was very noticeable. I took it into the shop they thought that it was something a computer program could reset they performed that I did not fix it, I don’t drive my Kia very much I barely have 25,000 miles on it right now I am a real live in care provider so I don’t drive very much my job is at home. I have taken the car into several dealerships repeatedly to have it fixed, IA really was at a loss and did not know what to do because I had taken it to two different dealerships and the problem was never resolved. I contacted an attorney they got nowhere because apparently I needed to take my car in one more time within a timeframe for them to be able to do anything about it? And any right, still to this day the car does the same thing it’s been in the shop four or five times for this problem. One time I took it to Kia and Elk Grove they kept it looked at it said they couldn’t find the problem. Every time I’m renting a car paying for the insurance going through the inconvenience of renting a car paying extra insurance etc. just to have nothing done with my car. When I went to pick up my car from the Elk Grove dealership I threw a fit because I was tired of it and I said look somethings wrong with the car I’m not a mechanic I can’t tell you

We would like to know what Kia is planning to do to address the fact that Kia built a car without the basic immobilizer circuit making it very easy to steal. Over the last few months, local and national news reports, as well as many social media sites, have reported on this security flaw which likely emboldens others to attempt a theft of a Kia and/or Hyundai. As I do not live in Milwaulkee, I would like to know how the company will fix this problem for the rest of us. It will not be restricted to just one city. There are numerous articles by victims that have detailed how their car theft cost them thousands of dollars in insurance deductibles, rental cars, and repairs. Many of the articles explain how thieves as young as 12 years old are able to still these cars in under a minute in broad daylight and driving recklessly creating a serious safety hazzard. Please advise what Kia will do to negate this serious security flaw.

While driving, car in motion, Front Passenger Seat belt Audio Warning Periodically goes off without reason. Indicating seat is occupied & seat belt needs putting on. When seat has been unoccupied / clear from any type of weight on seat to trigger sensor. Audio warning will continue until seat belt is latched over the empty seat. Local KIA Service Dept was informed & could neither confirm or deny its faulty behavior for it did not present itself during time of service. They said, wiring looked fine but did no further testing. To be honest they showed no interest into seeing any real importance for my concern for them to feel any further investigation was warranted. Its happened again twice since that service visit be it last incident Aug 7th. My concern is.... if there is faulty wiring or sensor signals being crossed somewhere, whats to say there is a passenger or no passenger in that seat, to ensure the correct signal is getting to the passenger side air bags of when to correctly deploy if an accident should happen with passenger in seat? This situ is only recent starting about a year a go. So something has changed from being fine for 2 yrs up to the last year that's now showing some kind of seat belt / sensor failure. I'm unfamiliar with how that wiring system works & linked within it for me know what other things I might need to pay more attn to, looking for other signs that could be saying is direct cause to the prob.

While driving at highway speed my children (11, 7, & 5) and I were almost rear-ended when my Kia Optima 2018 (79k) without ANY warning loses power, jerks and then regains power. A number of vehicles behind us had slam on their brakes to avoid a pileup. My Optima almost resembled the feeling when a vehicle runs out of gas but much more abrupt. The drink my son was holding was thrown out of hand due the vehicle jerking to an almost stop and jerking back to power. No warning light, battery & alternator both test good and tank was half full. Two days pass and the same system fail while driving with the same similarities (no warning lights). My Optima is no longer under warranty and I have no financial resources for repairs.

Driving at night, was getting onto the freeway. Entrance to the freeway was on a curved street, as I was taking the turn leading into the freeway the lights turned off, Then suddenly turned back on and then off again all while I was merging onto the freeway. I quickly took the light out of “AUTO” setting. Very scary as I almost got hit by the truckers already on the freeway. I’ve had issues with the blind spot warning as well. It fails all the time so of course I never put my trust on that. The lighting situation is very scary, as it was happening you could see the dashboard setting itself to AUTO and randomly going up and down the list of options as if it was being controlled by someone else. I could’ve caused an accident. Please check this issue.

Back in September of 2020, my car randomly went to limp mode while driving at highway speeds. Had the car towed to the dealer. Dealer advised of apparent “software issue” to correct the problem. Well this happened two more times after that twice the software was updated which didn’t work. The third time the replaced the knock sensor and so far I haven’t went to limp mode, however, the car has not drove the same and seems to get worse each passing day. Rough shifting, engine vibrates more than usual. Car struggles at times to go up hills, when giving gas a though way speed the car has a few second delay. Sometimes it feels as if the transmission is skipping. The car is up to date on all recommended services, I.e transmission flush and fill etc. There are also times when the vehicle is started but struggles. Almost as if it want to loose power but it doesn’t. Has happened numerous times however recently it actually didn’t start. Struggle to turn over a couple time but then finally did. A check engine light came on but then went away the next day after driving. I have an appointment with the dealer this week to look at this and other issues, again, hoping for some progress at that point.
