2018 KIA OPTIMA Unknown Or Other Problems

It started with the oil. I constantly have to add oil. when it first started that’s what I was doing just adding oil. Then it got worse the engine light started to come on and it no longer gives me the low oil warning. I took it to the dealership and it was there for about three weeks. They said that the car needed a system update, they updated it and i took it home after that. Its been about a year since then and my car is still having the same issue and getting worse. I had to change the spark plugs a few times since then i also have oil coming out the back pipe and it’s been doing this since before I took it to the dealership. I also had to spend money on a rental car while it was at the dealership.

I was sold an unsafe vehicle at J and J Auto house 6446 Wilshire Bl LA,CA 90022. Dealer withheld condition of car . Had car three months and was stranded on highway. Car was towed to Kia dealer and diagnosed with complete engine failure. Dealer will not honor limited warranty, shady sales practices withheld recall info during sale, won’t allow his mechanic to look at car, dodged calls, denied request to return car for refund

Paint on all four door handles are bubbling and chipping. I rarely use the backseat handles and passenger door, which makes it more likely to be a malfunction in whatever paint was used for the handles. There is no fading, chipping, or bubbling on other parts of my car.

Trunk latch broke leaving it impossible for someone in the trunk to get out and very difficult for someone on the outside to open the trunk

I’ve had the 2018 Kia Optima for a little over a year. I purchased it as a used vehicle. I’ve noticed that the car is utilizing an excessive amount of oil. Each time I get an oil change for the vehicle I am having to purchase oil to refill the vehicle about 2weeks to a month after. I’ve made multiple road trips where I’ve gotten the oil changed before leaving and I drove around 350 miles; halfway through the drive the oil was half empty on the dipstick. The first time this happened I was unaware of this issue and when I arrived to my destination after around 350 miles of driving, the car had little to no oil. I will provide store receipts of each time I had to purchase oil for the vehicle. I will also provide service interval receipts upon request. Dates of oil purchase are as follows: 1.7/18/23 2.8/16/23 3.10/20/23 4.12/18/23 5.2/7/24 6.2/29/24 7.3/18/24 8.5/4/24 9.5/11/24 10.7/9/24 Service intervals for oil changes are kept up with every 3-5k miles and can provide maintenance receipt.

Sudden loss of acceleration at freeway speed. Unable to start after incident. Unknown cause. Shop unable to diagnose.

In case of a vehicle lockout and keys are locked in the trunk when car is opened by locksmith there is no way to unlock the trunk from inside of the car the locks become disabled and you have to reset the master switch very inconvenient for emergencies. There is no trunk release or emergency Button to open the trunk from inside the vehicle. 2018 kia optima lx

Was driving on the interstate. The only light on was the ABS light and the car started smoking. Had to come to a stop as they were sparks coming from out under the car through it into park at around 15 mph steel jumped out of the car and within a minute the car was fully engulfed in flames.

Trunk latch is broken. Car doesn’t alert that trunk is open.

Excessive oil consumption 1-1.5 months approx. 1,000 miles into new oils change. It is available for inspection. Safety was put at risk due to not knowing there was no oil in my vehicle while constantly driving it as it did not display the oil warning sign on the dash board. The oil change dealership has confirmed an oil consumption issue two separate times. I am familiar with multiple people having this same issue with Kia and hyuandia vehicles. The dealership is requiring multiple steps to be paid out of pocket prior to using the full warranty i purchased to cover the issue even though they know what the issue is and how to fix it.

When we drive the car it hesitates as if it’s going to cut off and it keep burning oil. We have to put in at least 2-3 quarts in per week.

Ever since I got my car I’ve had black oil since the start . Second my car breaks on its own at times 3rd my car system keep breaking down as the sparks leaking in some where has this issue since bought it 2 years ago low miles

At around 40,000 miles my car started burning oil rapidly. No leaks were found and I would get an oil indicator light then the car would shut down while driving. I couldn’t get it to accelerate. Mechanic said Kia’s and Hyundais have been having those issues. I have needed oil changes every 3 weeks to keep in functioning.

Rough idle, chugged along before killing engine power. Has happened a couple of times. No check engine light has come on

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.

My car was stolen

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.

Me and my family just returned home from the laundry mat and took 2 children inside our house and turned around for our belongings and clothing/bedding for the family as the wheels spun out being followed by a silver hyundaii. Just a matter of seconds to 2 minutes. The keys were not in the vehicle. 2 childrens carseats and almost ALL of my family's belongings were stolen inside of the vehicle. 2018 kia optima dark slate grey in color with dark tinted windows and sun strip at the top of windshield, black rims.

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 what it is but I need this car fixed, the service manager came out and said I’ll take a a ride with you and we’ll see if maybe I can see what the problem is we didn’t even get out of the parking lot and it jerked so hard at the service manager noted it in the file had me drop it back off and leave it it’s still wasn’t fixed. I took it in again after that the new service manager took it on an hour drive on the freeway hooked up to a computer with Kia and of course it didn’t do anything while h

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.

WHEN I GOT IN MY CAR THE CHECK ENGINE CAN ON. I STARTED DRIVING MY CAR TO WORK, BECAUSE I WAS NOT SURE WHY THIS LIGHT CAME ON BECAUSE THIS WAS/IS A NEW CAR. I HAVE LESS THAN 19K MILES ON MY CAR. AS I ATTEMPTED TO GET ON THE HIGHWAY THE CAR REFUSED TO SPEED UP. THE MAX THAT I COULD DRIVE WAS 60 MPH. I HAD TO PULL OVER TO THE SIDE OF THE ROAD BECAUSE MY CAR WOULD NOT PICK UP SPEED. SO I CALLED THE SERVICE DEPARTMENT, WHO INFORMED ME THAT WHEN I BROUGHT MY CAR IN FOR AN OIL CHANGE IN JANUARY THAT THEY HAS PLACE A SAFTEY FEATURE ON MY CAR TO KEEP THE ENGINE FROM BLOWING UP. ACCORDING TO THE DEALERSHIP, THERE IS POSSIBLY SOMETHING WRONG WITH THE ENGINE, HOWEVER, THEY ARE STARTING OUT BY CHANGING THE WIRING FIRST. I CAN NOT EXPLAIN HOW DIFFERENT THIS DRIVES SINCE THE WIRES HAVE BEEN CHANGED. IT IS THE WORST DRIVE. THE CAR IS VERY LOUD IT DOES NOT PICK UP SPEED WHEN IT SHOULD AND IT DOES NOT SLOW DOWN AS FAST AS IT USE TO. NEEDLESS TO SAY, I AM HAVING ISSUES WITH THIS CAR AND SEEMINGLY EVERY TIME I TAKE IT IN FOR REPAIRS, THE CAR GETS WORST. I WILL NEVER EVER BUY A NEW/USED KIA AGAIN.

THIS HAS OCCURRED ON 3 TIMES SO FAR. I WAS AT A GAS STATION FILLING UP THE TANK, THE KEY WAS IN THE IGNITION, THE CAR WAS IN PARK, THE ENGINE WAS RUNNING, AND MY CAR DOOR WAS CLOSED. WHEN I FINISHED GETTING GAS, I TRIED TO OPEN THE DRIVER SIDE DOOR AND IT WAS LOCKED. ALL DOORS WERE LOCKED. I WAS 20 MILES FROM HOME FORTUNATELY SOMEONE WAS AT HOME TO BRING A SPARE KEY FOR ME TO OPEN THE TRUNK, PUSH THE REAR PASSENGER SEATS DOWN AND CLIMB THRU TO THE FRONT TO TURN THE IGNITION OFF AND UNLOCK THE DOOR. THE SAME SCENARIO OCCURED THIS PAST WEEK WHEN I HAD GONE OUTSIDE TO WARM UP MY CAR BY TURNING ON THE DEFROST FOR THE FRONT AND BACK WINDOWS. ONCE AGAIN, THE ENGINE WAS RUNNING AND I CLOSED THE DOORS. ONCE THE CAR WAS WARM, I TRIED TO OPEN THE DOOR AND IT WAS LOCKED. I HAD TO GO IN THE HOUSE TO GET THE OTHER SET OF KEYS, OPEN THE TRUNK PUSH THE BACK SEATS DOWN AND CLIMB THRU THE TO THE FRONT, TURN OFF THE IGNITION AND UNLOCK THE DOOR. THIS LAST OCCURENCE WAS ONCE AGAIN AT A GAS STATION, THIS TIME IT WAS LATE AT NIGHT, IT WAS 20 DEGREES OUTSIDE AND HAD TO WAIT FOR SOMEONE FROM MY HOUSE BRING THE SPARE KEYS. THE QUESTION I HAVE FOR MYSELF IS, WHAT AM I GOING TO DO IF NO ONE IS AT MY HOUSE TO BRING THE EXTRA KEY. SURELY, I DONT PLAN TO BRING TWO SETS OF KEYS WITH ME. EVERYTIME I'VE TAKEN IT TO THE KIAOFDAYTON SERVICE CENTER, I AM TOLD THEY CANNOT RECREATE THE ISSUE. I'VE TAKEN IT TO THE DEALERSHIP TWICE. IT'S VERY FRUSTRATING. IN EVERY INSTANCE THE CAR WAS IN PARK, THE ENGINE WAS RUNNING, AND THE DOORS WERE UNLOCKED WHEN I HAD EXITED THE VEHICLE. WHEN I ATTEMPTED TO GET BACK IN, I COULD NOT BECAUSE THE DOORS HAD LOCKED BY THEMSELVES.

THE VEHICLE IS STATIONARY. THERE IS NO EMERGENCY TRUNK RELEASE FROM THE INSIDE OF THE VEHICLE EXCEPT FROM INSIDE OF THE TRUNK. MY KEYS WERE STUCK INSIDE THE TRUNK THERE IS NO WAY TO OPEN IT. THE TRUNK RELEASE BUTTON FROM THE DRIVER SIDE DID NOT RESPOND. THE TRUNK RELEASE BUTTON FROM THE TRUNK ITSELF DOES NOT RESPOND. THE REAR SEATS CANNOT FOLD FROM THE INSIDE EITHER, BECAUSE IT CAN ONLY BE ACCESSED FROM THE TRUNK
