THE FUEL PUMP HAS AN ACTIVE RECALL. TOOK ITIN TO DEALER AND WE ARE BEING ADVISED KIA WILL NOT COVER THE COST. THEY HAVE AN ARTICLE OUT THAT CLEARLY STATES THEY WILL COVER THE COSTS. THE CAR WREAKS OF THE SMELL OF GAS AND WE ARE SCARED IT WILL CATCH FIRE.

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.

I slowly pulled into the parking lot at work coming around a corner with my break song slowly to see if anything was coming from the other side, pull it around to THE back looking straight ahead to pull into my parking spot as I pulled into my parking spot mind you I have had my foot on the break before. I got there and I got into the park spot. I hit the brakes and the brakes went to the floor multiple times and the car just searched straightforward into the brick wall of the building.

I purchased my 2018 Kia Optima directly from the dealership, brand new. I've had the vehicle since then and have followed all of the warranty guidelines and only went to them for oil changes & other maintenance issues. Since February 2023 I've noticed where i've been having oil loss, but no sign of an oil leak. When I first noticed this, I would take a turn and my oil light would come on. I'd check the oil and it'd be low so I would refill my oil. However, this was happening 2 months after my last oil change which wasn't normal. I took the vehicle to Kia and they did an "Engine Consumption Test" where I had to drive for 1000 miles with a seal on the drain plug. After the 1000 miles, I came back and I was only 1/2 quart low. According to Kia it didn't meet the guidelines for engine replacement so they topped off my oil and I left. About 2 weeks after, my oil light came back on. I went back to Kia and spoke with the Shop Manager who stated I was 3 1/2 quarts low! He added oil to my engine and we did another round of the consumption test. When I came back in after that, I was 2 quarts low so that meant I qualified for a "Consumption Cleaning". They kept my vehicle overnight & I had to drive another 1000 miles. When I came in after my 1000 miles again I was only 1/2 quart low and therefore Kia said there wasn't an issue. I've reached out to multiple auto repair shops who state it is a Kia problem, that the engine is using it and processing it out of the exhaust. I don't know what

Excessive Oil consumption. Manufacturer specs 1 quart of oil to every 1000 miles to be added. I'm adding 1 quart for every 500 miles. Advised kia and had oil consumption test and was told nothing is wrong. I am having to add extra oil 0so engine does not seize causing a safety issue for people in car. The car randomly spits smoke out.

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

What component or system failed or malfunctioned, and is it available for inspection upon request? ******Speed Control- Vehicle will stall while on road/ highway causing rear vehicles to brake. How was your safety or the safety of others put at risk? *****Several times I was forced to pull over to side lanes to avoid being rear ended. *****Has the problem been reproduced or confirmed by a dealer or independent service center? I have called dealership several times in regards to this issue, all I was told was to do not use A/C or heater as that will make the vehicle lose power. Refused to conduct was full inspection of vehicle. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? *****No, no it has not been inspected Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? *****No warning lamps not symptoms of the problem prior to the failure.

My engine is under a million mile warranty because it burns 1qt oil/1,000 miles. My engine burns just under 2 quarts of oil about 800 miles. For long trips, this is very unsafe because my engine is going seize or burnout on the highway at some point. This will put my life and possibly that of other drivers at significant risk.

Vehicle stated was consuming a large amount of oil by burning it. this was able to be determined by the lack of oil or residue anywhere on the engine or engine compartment. It was then taken to the dealership were it was determined an engine oil consumption test needed to be done. the test was done and was determined that it needed an upper engine combustion cleaning to correct issue. The vehicle was then scheduled to have this procedure done. upon completion of this procedure the vehicle continued to burn oil as it could be seen out of the tailpipe upon acceleration. a second oil consumption test was performed and was found to be within dealer specs of acceptable oil consumption at 1qt per 1000 miles. When the next oil change was done by an independent garage, it was noted that the vehicle was now leaking oil from what appeared to be the oil drain plug. The dealer was then informed with pictures of the oil leak. The vehicle began leaking more and more oil now at a rate of 1/2 qt a day as of writing this the independent garage inspected again and found that there was a crack in the oil pan just to the side of the oil drain plug. After doing some research it appears to be a very common problem. The vehicle in question is supposed to be taken into dealership to have the issue checked out on the 4th of October 2023. todays date is 9/26/2023.

Car will NOT go pat 60mph and i haven’t had this car just over 6 months. And the camshaft sensors are gone out. Smoke comes out the pipe when mash on gas…. It is really a bad vehicle. And Southeast auto refuses to fix it. I really honestly think the motor is bad in it. Because I been having issues with it since I had it

Car is burning to much oil and have to change oil every three thousand miles

Leaking gas at the firewall when running.

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.

Purchased my car in june of 2019. Ive scheduled regular oil changes and maintenance until june of 2020 where the engine light began to flicker and the car would shake. I took to Koons Kia owings mills md and it was repaired. Next year same thing. Oil compression issues all year round where i have to keep putting oil in. Now my car starts and shakes violently. the kia service modurator on the car indicated there were an engine issue. I cannot keep dishing money into this car with so many recalls (current fuel pump recall and anti theft issue) is also included. Please help

I'm reporting these issue pertaining to the engine within the first 3 weeks AFTER the engine replacement recall was serviced and completed. The vehicle was exhibiting the same defects and major health and safety hazards as before the new engine. Intermittent engine failure, even worse, while i was trying entering the hwy at speeds of 45-50 miles it jerked very violently and loss total power while vehicles were behind me nearly rear ended. Prior to this I reached out multiple times to have it serviced at again. The original service department didn't respond, so I called other service departments and was told it needed to be serviced by the original dealership/service department that replaced the engine. I had the vehicle in normal working conditions a few days before it began exhibiting the same problems as before the engine replacement. It was in operable condition but still stalling and refusing to crank unless primed, until it ultimately just would not crank at all and is back in the same condition it was before the new engine but it is not locked up currently. The time frame and Milage between first experiencing the issues to now, March 2023-64745 Started shuddering, loss of power while driving, but would crank right back up without issues. Happened a few times, charged up battery thinking is was am electrical issue. April 2023 More frequently the issues occurred, still same severity levels. May 2023 Began happening every time at an idle, whether I was at a fast food in dr

My vehicle is under a engine / oil consumption recall, I have contacted kia multiple time in regards to this issue as the vehicles are having engine fires due to this. I was advised by kia that my vehicle is under recall and has lifetime warranty but they will not fix or swap the motor until it goes out. This is a huge safety risk I am literally scared to drive my vehicle due to not knowing if the engine is going to go out at anytime or start on fire in the middle of the expressway.

The braking system "catches" at 13mph regularly. It feels like the brakes are being applied or the vehicle is downshifting when it is decelarating to around 13mph without any actual braking being manually applied. So far no safety risk, but if the brakes fail at any point for any reason, there will be potential for great risk. The local Kia dealer was able to reproduce this but had no explanation, no recommendation, and no further advice or assistance was offered. At this point, the Kia dealership is the only entity to inspect this issue. There are no warning lights or indicators of failure or problems, but this issue has been ongoing since the vehicle was purchased.

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.

Was driving vehicle on freeway, around 65 mph, smooth road, no bumps, no indication of any road debris and suddenly heard a loud cracking/exploding noise which was extremely startling. After hearing some outside wind noise and the sound of glass pieces rattling, I realized that the glass panoramic sunroof must have broken somehow. Luckily I had the interior fabric shade closed, so no glass pieces entered the cabin to injure anyone. After getting out of the car, I could see around a 12 inch diameter hole in the sunroof glass. The remaining glass that was still attached was full of cracks. I have created a case with Kia Consumer Affairs and waiting to hear back from them. The vehicle has not received any outside inspection as of yet for this incident. There was no prior warning to this issue, no creaking noises or visible cracks.

Engine failure just like all the other optima’s.

MY ENGINE STARTED MAKING A HORRIBLE NOISE AND JUMPIMG. THE OIL WAS JUST CHANGED AND IS FINE. HAVING TO REPLACE ENGINE AND ONLY HAD CAR 2 MONTHS

Knock sensor detection system. Driving and all the sudden felt like it hard down shifted… car behind me almost hit me. Engine light started flashing so I pulled into autozone and plugged it in and got the knock sensor code. It’s had oil consumptions issues for a while. It’s so dangerous to drive with limited power and speed

I purchased this vehicle used in April 2023 with 3,000 to go prior to another oil change. I returned home from a trip and the oil light would come on only while turning or braking. When checking the oil there was no oil in the motor. The reservoir was filled and two weeks in the engine is low on oil again. There are no leaks. The car jerks at lights as if it wants to stall out. I feel unsafe driving this car.

High injector fuel pump top engine mount went out at 68000 miles. It caused the vehicle to stall and lose power and basically cut the car off while driving.

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

-Knock Sensor Detection System - ECU Logic Improvement - I Was driving with my infant son in the backseat. I was going 70 mph when my car started rapidly losing speed. This happened again with just myself after receiving the car from mechanic. There was heavy traffic and I had to swerve to avoid being hit by an 18-wheeler. - I can see on the website where I received the car from, there is a recall for my exact make and model with the same code but they say there is no recall for my specific car. - The check engine light started flashing and Kia Systems starts talking.

Car smoking white , and driving slow after I hit a pothole when it was raining hard.

My car had been consuming 2 quarts every 1,000 miles for the past 3-4 months and the kia dealership told me that the best thing i could do is keep getting an oil change. So one day i tried starting my car and it starting shaking and turned off so i turned it back on and it shut off again. I jump started it and it shut off again and i jump started it again but it never turned on. All of the problems that i have has been confirmed by the dealership (Open Road Automotive) My engine is all the way messed up, my fuel pump was messed up .My engine light came on after this and i just keep having problems with my car. I seen that kia keeps having these problems but i chose to get my car anyways because I love kias cars but I will have to switch if these problems are not solved with my car and i get new parts on my car because these are failing parts not because of me. I’m having So many problems with my car right now and it’s been costing me a lot of money .It’s at the shop right now and it’s been at the shop for maybe 2 weeks now. I can’t get a rental because they are only covering $40 a day and they are charging me $200 a day. So please help me with these problems and get these problems fixed.

Consistently getting oil changes. if the car doesn't rcvd an oil change before 3000 miles the check engine light comes on and then the light removes after oil change. in between the time period of getting oil changes it may run junky or you hear the catalytic converter trying to push air thru and it rattles.

My car engine burns oil EXCESSIVELY. After an oil change, 2 weeks later i had to put more oil in. The dealership is no help even with a warranty. The car burning oil is also causing other mechanical problems that are a hefty price that are only a temp fix. I have to put oil in every single week. 2-3 quarts a week. Due to the oil being burnt off, it has affected my spark plugs and has caused a misfire in the same exact cylinder for when it misfired for this same problem, a year prior. I took it to a kia dealership last year and they performed a combustion chamber cleaning ($650+) and it only worked for 3 months before my car was back to performing poorly due to power loss from misfiring again. This car has put me in a VERY TOUGH financial situation and the dealership and corporate are absolutely no help. a year apart, this car has misfired on the same cylinder twice. the dealership just tells me to do a combustion cleaning but due to it being very pricy and with how much oil i have to buy, it’s not an option for me due to my financial situation. right now i’m just hoping something will be done for the millions of people that are effected by this.

The engine consumes all the oil within 1000 miles. The oil light comes on around 800 miles after oil change. The dealership did the 3 separate tests and they all failed. Dealership stated the engine is faulty however Kia corporate denied the claim. There is already a class action lawsuit in progress in California.

Headlights randomly turn off while driving. To get them back on you have to switch on and off before they turn back on. Very dangerous for my 17 yr old daughter driving down a highway at night. The lights will also turn on in the middle of the night and if we happen to notice, we have to go to the car and turn the lights on and off to get them fixed. There are numerous reports on this when Google. I am not the only one. Really dangerous!

2018 KIA OPTIMA EX A/T. MY WIFE DRIVE THIS CAR TO WORK EVERY DAY, 45-50 MILE ROUND TRIP FOR THE PAST COUPLE YEARS. WE HAVE NOTICED THAT OIL CONSUMPTION IS STARTING TO BECOME A PROBLEM. IM UNSURE THE EXACT AMOUNT IT GOES THROUGH BUT IT SEEMS TO BE ALMOST 3-4 QUARTS BETWEEN OIL CHANGES. EVERY NOW AND THEN IT WOULD RANDOMLY BE A QUART LOW, BUT NO LEAKS, NO NOTICEABLE SMOKING, NO CHECK ENGINE LIGHTS. MY WIFE HAS HAD A FEW TIMES WHERE THE CAR WOULD RANDOMLY LOOSE ACCELERATION NAD SLOW WAY DOWN. THE CAR WOULD COME BACK UP TO ACCELERATION AFTER PULLING OVER TO THE SHOULDER OF THE FREEWAY WHEN IT HAPPENS. IM WONDERING IF IT MIGHT BE RELATED TO THE OIL CONSUMPTION, BUT NOT SURE. IT HAS THE RECAL FOR THE KNOCK SENSOR UPDATE WHICH WE ARE WAITING FOR FEB 28TH, THATS THE TIME THE DEALER CAN GET THE CAR IN FOR IT. OUR CLOSEST DEALER IS 150 MILES FROM HOME. WE HAVE OWNED IT SINCE NEW AND THIS IS THE ONLY PROBLEM WE'VE HAD WITH IT. I HOPE WE CAN GET THIS RESOLVED. NO NEW CAR SHOULD GO THROUGH THIS MUCH OIL AT ALMOST $6 A QUART OR MORE.

Front brake calipers seize and burning smell and smoke coming for front wheels. Have replaced the rotors, calipers and brake pads(twice) and it does not seem to fix the problem.

Excessive oil consumption will burn through around 4qts of oil before 1k miles

Normally, when the doors are open my car will tell me. The doors notify me that they're open but my trunk was not showing that it was open. It blinks when it is. Due to that I was driving and my trunk seemed closed and it just flew open. So the problems I'm having is that my trunk will not show its open but it also will not close AT ALL due to the latch. I literally had to bungee it closed. This is dangerous. I have seen many recalls in other kia's and hyundai's just like this. This is very dangerous and needs to be recalled and/or fixed.

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.

UNKNOWN When slowing to a stop, the vehicle spontaneously makes a sudden jolt, throwing passengers forward. It’s as if the the transmission malfunctions when down shifting and results in engine braking.

The contact owns a 2018 Kia Optima. The contact stated that when the vehicle's oil will be as low as half a tank or lower the engine would suddenly stall. The vehicle would immediately regain power and function as expected. The failure occurred at various speeds with the highest speed being 60 mph.

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

Just Started Having Problems On It’s On The Car Only Has 38,000 Miles

My car is consuming 2 quarts of oil for every 1,000 miles. This falls under the oil consumption that needs a motor replaced and I am getting a run around from the dealership about getting it replaced. They are saying that Kia does not like to replace the motors and I'm better off trading it in. I bought this car intending on keeping it long term, not purchasing a new one. All of the regular maintenance has been done on the vehicle. I've been into the dealership a multitude of times a month due to issues with the car.
