I purchased a used 2019 Kia Optima from a dealership in January 2025 with 103,000 miles. 11 months later it's burning oil. Every 2 weeks I have to add a quart of oil. I took it to my mechanic and they found cylinder 4 has been burning oil. They also found a technical service bulletin related to engine oil consumption. They recommended replacing long block assembly. They referred me to a Kia dealership. Currently, my vehicle is at a Kia dealership. They performed a "leak down test" and found cylinder 4 has been burning oil and recommend a long block assembly. I have a 3rd party warranty on my car. They are currently reviewing this claim. If they decide to replace the long block assembly, there will be additional uncovered costs that I feel Kia should be responsible for. I have only put 7,000 miles on this car since I bought it 11 months ago. The car currently has 110,500 miles on it. I understand this is a used vehicle but engines should last 200,000+ miles. I'm trying to figure out my rights. By law isn't the dealership responsible for this oil consumption loss and long block assembly replacement?

I recently had the engine replaced less than a year ago due to an engine recall on this model car, today 11/11/2025 the engine caught fire. We’ve kept up with oil changes on time and I had no alerts in the vehicle on the dash claiming the engine was hot.
Nov 11, 2025
Over the past couple years, the check engine light has came on and I immediately had a mechanic look at it. The first time they said it was my spark plugs and changed them. Then this year, a year later, the check engine light came on and it became hard to accelerate on my way to a mechanic. Once again, they said spark plugs, so they changed them and claimed that they didn't look to had been changed before. Now here I am a couple of months after that, my check engine light came back on and my car started making a funny noise on my way to work. I turned back around and went home since I was closer to home than work. It sounds like rocks popping when you start it or hit the gas. I had someone check the codes and it said engine 1 and 4 coils. All 4 coils and spark plugs were changed again. That did not fix it. The sound is still there and the engine light is now blinking. I have kept up with the oil changes and everything. There is no recall. I still owe on the car and it is not able to be driven.

I purchased this car off the show room floor in 2019 with only 10 miles on it. At some point in 2022 my car was slow to accelerate. I received the recall letter September 16,2022. no appointments until 08/09/2023. It didn't help .It was still stalling two weeks after. I have talked to the manager numerous occasions. He said it sounds like the transmission. The parts manager told me he will keep it overnight so his mechanics can drive it the following morning. That didn't happen. This car is a safety hazard. I can't pull out in front of anyone due to the car stalling. My family like to have lost our lives this weekend 05/31/2025 due to the car failing to accelerate(stalling). I have filed complaints with KIA head quarters twice. They keep telling me that if there's no warning lights on they can't identify the problem. On 01/06/2025, the manager and parts manager agreed to keep my car for a couple of days. I paid for my oil change/tire rotation and they sent me on my way. the bottom line is this car will be the death of me. God forbid!!

I own a 2019 kia that is garage low milage 35,757 when not driving. the paint had a spot of paint missing on the hood and i ordered touchup paint to protect and before it arrived i noticed a larger spot. I drove to town and a large spot flaked. I call the dealer and they said they didn't handle that. I called kia customer service and they said would write a work order and i haven't heard any thing from them. i have gone to computer to see if any recalls and none. there are a lot of complaints from owners but no help from Kia . I read an article from Kia that they had stopped using the pearl white paint due to so many complaints. This need to be address and something done. I took to a reputable body shop today and received estimate and it was not just my hood found spots on right fender and trunk with estimate of almost $4,000.00 . I can not make Kia repaint my car and i can not leave it to rust nor can i afford a new car. Canada did recalls on this matter the United States needs to stand up for the people of the United States.

On October 30th 2024, I purchased a 2019 Kia Optima from San Diego Chrysler Dodge Jeep Ram. On November 26th the car was stolen from in front of my house, while the alarm was activated and the key was in our possession. I went online to the Kia website to find some information and found that there was a recall on that vehicle to install an anti-theft device. San Diego Chrysler did not have this done. I contacted them in regards to that not being done and they replied that they offered me to purchase a GPS system. They don't seem to feel anything was done wrong but if a car has an open recall, it would seem that a dealer needs to have that done PRIOR to selling a car to a consumer who is unaware of the theft problem. I had the car for three weeks, lost my trade-in, deposit and still have it financed. Big conglomerates need to be held accountable.

I own a 2019 Kia Optima whose paint is peeling off rapidly. The paint began peeling in a tiny spot that I thought was a chip from a rock but has now grown to several spots peeling all over. I first noticed this in 2020 I visited my dealer on January 2024 to no avail. Not only was their technician rude, but he also said the paint was not covered under KIA’s bumper to bumper warranty. I have bought the extended bumper to bumper warranty at the dealer. I’ve owned several cars in my life and have never had this problem with any of them. I currently own a 2003 Toyota whose paint is in much better condition than my 2019 Kia. I believe this is a factory defect with this paint color and would like you to further investigate and help to restore my KIA so that the peeling stops. I’m attaching several photos for your review. The color is Snow White Pearl.

Clear coat paint is peeling rapidly on the driver side door. This is the only affected area and this car has never been in an accident, so it’s the original manufactured part. Car has 59K miles on it

AIR BAGS
10 complaints
I brought my Kia Optima into the dealership in October 0f 2024, because my airbag light came on. It has not been there over 6 months because my passenger airbag module is not operable and rending all my airbags useless; it is also on backorder with no ETA. The dealership wouldn't help with my escalation it has taken me 6 months to get to the escalations department and now they will not offer additional support with payments or a buy back "due to warranty". I feel helpless and like my investment has been thrown in the trash and lit on fire as my car is sitting in the parking lot in the AZ sun, not being moved and not protected from the elements. They continue to offer no real resolutions and tell me to wait for a piece that has absolutely no ETA.

FORWARD COLLISION AVOIDANCE
10 complaints
It was snowing and an icy day Jan. 21 in Atlanta, Georgia. I was driving on Buford Spring Connector going southbound. I was on a bridge and it was completely white and icy. I saw there was a car stopped in front of me. I tried to put on my breaks and my car would not slow down. I was getting closer to the other vehicle still trying to break. I tried to use my electronic emergency brake and it did not engage. The car did not even try to break for me which it normally does if I moving faster than a stopped car in front of me. I rear ended the person in front of me. I just wanted to let someone know as the forward collision did not work in this case and the accident could have been avoided.

The contact owns a 2019 Kia Optima. The contact stated that while her son was driving at an undisclosed speed, the Forward Collision Avoidance system inadvertently activated, prompting the vehicle to inadvertently stop. The contact stated that there was no other vehicles or objects nearby during the failure. The vehicle was taken to the dealer, who advised the contact that an unknown obstruction on the Forward Collision Avoidance sensor had possibly caused the inadvertent activation. The vehicle was not repaired. The manufacturer was not notified. The failure mileage was 54,000.

Pearl white paint peeling prematurely
Sep 08, 2025
I am the owner of a 2019 Kia Optima SX Turbo in Snow White Pearl (SWP) paint. At approximately 100,000 miles, I observed bubbling and peeling of the paint—no collision or exterior impact occurred to trigger this. The peeling area has since enlarged, exposing the underlying primer or bare metal, which is visible in an attached photo. I contacted Kia around 115,000 miles when I fully realized the paint failure. Kia declined to offer any repair or goodwill assistance, citing that the vehicle is no longer under warranty. However, this is a widely reported defect affecting many Kia and Hyundai vehicles with the Snow White Pearl paint. Numerous owners have experienced similar peeling and flaking without misuse or accidents. This is clearly a manufacturing defect in paint adhesion, rather than normal deterioration. It compromises both the vehicle’s aesthetics and resale value, and it may lead to rust or more serious long-term problems. There are pending class-action lawsuits in Canada for identical issues with SWP paint. Yet, U.S. owners are left to manage this defective condition on their own, without support from Kia. I respectfully request the NHTSA open an investigation into this paint failure issue involving Kia vehicles painted in Snow White Pearl, including the 2019 Optima, and consider issuing a recall or a mandatory repair campaign.

SERVICE BRAKES,FORWARD COLLISION AVOIDANCE
6 complaints
I just recently purchased my 2019 Kia optima sx turbo. After purchase, I immediately began experiencing issues with the braking system and the forward collision warning light coming on. The cruise control stopped working as well. I googled and saw that there was a recall on the forward collision warning system but the local Kia dealership to me says there is not one. I almost had a head on collision in this car with my granddaughter coming from daycare as I completely lost brakes. I have put so much money into purchasing this car believing it to be a good car.
Nov 16, 2025
I was doing 65 on the hwy when Forward collision started so sound off and slowing down car when there was no other car around me this happened on several occasions
Feb 24, 2024
I was driving and tried to brake but my car did not stop and ended up hitting guardrail. A couple weeks later I was driving and there was nothing in front of me but the car abruptly stopped in the middle of road
Feb 04, 2024
On October 11,2022 I was involved in a vehicle collision that resulted in damages to the front of my vehicle and the rear of another. My two children and I suffered injuries that we were not able to recover fully from. The driver of the other vehicle was uninsured and has not been accessible!
Apr 04, 2023
To begin, there was a recall on the forward avoidance collision system. The fix was to have the system reset at the dealership. Almost like a system update. I had that done after multiple lights appeared on my dash. 5 months later, the lights would illuminate again periodically, but turn off after a few minutes of driving. Two months ago, the lights came on when I was traveling on our highway at about 45 MPH. There was no cars in front of me, nor any objects. The automatic brake applied itself as I was turning off of this major highway. I hit the gas to try to turn off of the highway after the brake was applied, and my car wouldn’t accelerate. Since then, the light has stayed on every time I turn my car on, and for the remainder of the time I’m driving it. The brake has also self engaged itself twice since then. It’s a huge safety risk as someone could hit me from behind. The system update obviously didn’t fix the issues. The Kia dealership in my area, Tameron Kia, said that there was nothing they could do for me since they did the computer update. She was certain that it was a different issue, but it isn’t. My car has 60,000 miles on it and have been dealing with this specific issue since 3 months after I purchased the car. It’s not safe for my children and I, and something has got to be done about the issue.

THE BRAKES DID NOT ENGAGE WHEN APPLIED. THE ROAD WAS DRY. SPEED WAS 30 MPH OR LESS WHEN I ATTEMPTED TO STOP AT A LIGHT. THERE WERE NO CARS AHEAD OF ME, AND I HAD PLENTY OF TIME AND ROOM FOR A REGULAR STEADY DECELERATION. THE BRAKES DID NOT ENGAGE. JUST BEFORE I CROSSED INTO THE CROSSWALK THE CAR BEGAN TO BUCK AND THE BRAKE PEDAL FORCIBLY KICKED BACK EXACTLY FOUR TIMES, AND THE CAR FINALLY CAME TO A STOP. THIS HAPPENED ON A STATE HIGHWAY THAT ALSO SERVES AS A MAIN STREET RUNNING THROUGH DOWNTOWN. I WAS TRAVELING ON A STRAIGHT SECTION OF ROAD. I HAD THE CAR TOWED TO THE DEALERSHIP. I HAVE OWNED THE CAR, PURCHASED NEW, FOR 19 MONTHS. MILEAGE IS 17,325. THE DEALERSHIP CAN FIND NOTHING WRONG AND SAYS THE COMPUTER DIDN'T REGISTER THE EVENT. WE ASSUME THE BRAKES FAILED AND ANTILOCK BRAKES ENGAGED IN AN EXTRORDINARY MANNER. I HAVE NO DOCUMENTATION AS THE CAR IS STILL IN THE SHOP 37 ODD DAYS LATER. THEY STILL SAY THEY HAVE NO IDEA WHAT MALFUNCTIONED.

FUEL/PROPULSION SYSTEM
4 complaints
After routine maintenance replacing the valve cover gasket, the low pressure GDI fuel line developed a leak in an area away from where the maintenance had occurred. After a 10 minute drive, the car developed a fire in the engine compartment. Upon investigation by an independent auto mechanic, it was determined that the fuel line had become brittle and developed a crack that had sprayed fuel into the hot surfaces of the engine compartment. This appears similar to the scenario affecting earlier Kia Optima models with the 2.0L Turbo engines. The heat from the fire caused the brakes to start to fail and the amber check engine light to come on within about 5 seconds before smoke was observed coming from the engine compartment. Fortunately, the fire occurred as the vehicle was pulling into the owner's driveway and a fire extinguisher was nearby and used to put out the fire. The vehicle's occupants were able to exit the vehicle with no injuries.

2019 Kia Optima EX - 59,000 miles - car miss fires and shakes on start. After a few seconds the car calms down and I can drive. Very dangerous since the fuel can stop flowing and the car can stall at any speed. Very dangerous!! Looks like several Kia's from 2019-2023 have been recalled for the same issue - High Pressure Fuel Pump - if my car is having the same issue at 59,000 miles why is this car not recalled, Very Dangerous! The Kia K5 which took over for the Optima is on the list why not the Optima EX.
Sep 30, 2025
Our 2019 Kia Optima has now stalled twice at a stop light in the past year. When it happens, we're able to restart the engine. In addition to stalling, the car struggles to start on some days and runs lumpy (minor surges in power) on other days. The symptoms match a problem Kia is aware of and for which it has provided an extended warranty (15 years/150,000 miles). Below is the wording from the extended warranty letter (2016-2020 MY Kia Optima Vehicles Low-Pressure Fuel Pump New Vehicle Limited Warranty Extension dated Sept 9, 2022): "If, at any time within the extended warranty period, you experience intermittent reduction in engine power, stalling while at idle, and/or inability or difficulty starting your engine, your authorized Kia dealership will diagnose the cause at no cost to you." When I took the car in after both incidents, the Kia dealer is not able to replicate the issue because it's an intermittent issue. There is no fault code thrown by the vehicle computer. The dealer and I have separately called Kia to get authorization to replace the low-pressure fuel pump (the most likely culprit), but Kia has denied the request because the dealer isn't able to replicate the issue. This is non-sensical given the fact that Kia in its letter admits that this problem is intermittent. I'm afraid that the next time the low-pressure fuel pump fails, it will be in a far more dangerous situation (e.g. highway) than at a stop light. I believe Kia should replace the low-pressure fuel pump for those owners who report the symptoms of a failing low-pressure fuel pump even if the failure can't be replicated at the dealer. Kia is basically saying they're not going to replace the low-pressure fuel pump until it malfunctions and stays broken which could very likely leave us stranded somewhere or worse without engine power in the middle of driving.

The morning of 9/26/2023 as I was driving on the freeway road and I experienced an intermittent reduction in engine power and had to pull over on the side of the freeway road. This was a very traumatizing experience and I was very lucky that I was not hit while awaiting to be towed. After my mechanic inspected my vehicle we received error code P1233 and advised me to call the dealership as this is something covered under an extended warranty. I scheduled an appointment for 9/27/2023 however, I dropped my car off on 9/26/2023 since I was able to arrange dropping it off a day earlier. I received a call very early on 9/27/2023 from Chuck, one of the mechanics at Westside Kia and he stated that my car was working perfectly fine. After I informed him of the issue I had he stated they would need to keep my car for about 48 hours until they could determine the issue. I received a call from Chuck on 9/28/2023 and he stated that the issue with my car was not covered under the extended warranty and that I would have to pay $1,200.00 to get the issue fixed. He agreed that the issue was in relation to the low pressure fuel pump and should be fixed at no cost however, he stated the only way this could be fixed is if they received approval from Kia Consumer Affairs. On 9/27/2023 I opened case number [XXX] and after a month they denied my case stating that they will not fix my car free of charge because the fuel pump needs to be replaced and the recall only takes care of replacing the filter and not the pump itself. I have argued with the dealership and Kia Consumer Affairs that if the fuel pump goes bad due to a bad filter that has been recalled then it is their responsibility to cover the cost.

The contact owns a 2019 Kia Optima. The contact stated that while driving at an undisclosed speed, the oil pressure warning light illuminated. The contact stated that shortly afterwards, the check engine warning light illuminated, and the vehicle started losing motive power while attempting to accelerate. The contact stated that the vehicle was shuddering and jerking while driving. The contact also stated that the Forward Collision Avoidance sensors activated inadvertently while driving or the vehicle was parked. The vehicle was taken to a local dealer where it was diagnosed with excessive oil consumption and the contact was advised that the failure with the Forward Collision Avoidance sensors was the regular function of the vehicle. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 57,813.
Jul 31, 2024
The engine is consuming oil very fast and needing oil way before the next oil change. The oil consumption test Kia did stated that it was 2 quarts low after the first 1000 miles. Car does not have extended warranty but this a manufacturing defect. Suggestion was new motor. Also it's recall for the forward collision safety feature but my car vin is not included even though it goes off when nothing is in front of me. They want me to pay for these issues the motor cost the same as the payoff of car. This is ridiculous, I purchased Kia due to having a older model that almost got 300,000 miles on it before transmission died. I got a great payment and a newer car but didn't expect to have this motor issue or safety problem with no help from manufacturer. I'm stuck keeping oil in car so it's burn out & cutting safety feature off so it stops breaking when nothing is in front me. Both of these issues or manufacturing defects and should be fixed by KIA.
Apr 05, 2024
The second month after I purchased this vehicle the master warning light and forward collision light popped up and car vehicle started de-accelerating in the middle of the freeway and I had to pull over and then the car died. Repeatedly took my vehicle to the Kia dealership and no one still has been able to help me. They claim no one at their corp. Office in California what that means so it has been going off ever since and I don't want my vehicle to died again. PLEASE HELP!!!

This car was equipped with the theta ll engine and I believe that’s what caused it because it was an electrical smoldering. The car has been signed over to the insurance company, it was totaled. If this had happened 30 minutes sooner, I would have been burned. Me and my daughter had luckily just got out of the car. No the problem has not been confirmed by a dealer. It has not been inspected by the manufacturer, but has been inspected by police and insurance. There was not any warning lamps or messages prior to the incident.

My vehicle is consuming oil excessively. I have to put a whole quart of oil in my vehicle every 2 weeks. I am adamant about getting regular maintenance oil changes as well. My car had to be towed to a local auto shop due to the engine stalling and accelerator not working. They had to replace all 4 coil packs and 4 spark plugs due to dark, tarry oil covering the parts. The repairman told me my engine was at risk of failing, and that the repairs he did would not last without a new engine. I am worried about the car stalling or failing while driving, which puts an accident occurring at greater risk. My complaints resemble symptoms tied to previous Hyundai/Kia engine recalls. I am requesting investigation and manufacturer action related to this issue.

Subject: Complaint Regarding Excessive Oil Consumption and Engine Hesitation in 2019 Kia Optima SX To Whom It May Concern, I am writing to formally lodge a complaint regarding my 2019 Kia Optima SX. Despite meticulous maintenance and care, I have been experiencing significant issues with the vehicle that are concerning, especially considering its relatively low mileage of only 107,000 miles. The primary issues are as follows: 1.Excessive Oil Consumption: My Kia Optima SX has been burning an excessive amount of oil, necessitating frequent top-offs well before the recommended oil change intervals. This is not only inconvenient but also raises serious concerns about the long-term health and reliability of the engine. 2.Engine Hesitation: The vehicle exhibits extreme hesitation during acceleration. This hesitation occurs sporadically, making it difficult to anticipate and presenting a potential safety hazard, especially when merging onto highways or attempting to overtake other vehicles. These issues are unacceptable for a vehicle with such low mileage and are not in line with the quality and reliability I expected when purchasing a Kia. Given the prevalence of similar complaints from other owners of the same model, it is evident that these are not isolated incidents but potentially indicative of broader manufacturing or design flaws. I urge the National Highway Traffic Safety Administration (NHTSA) to investigate these issues thoroughly. Owners of the 2019 Kia Optima SX should not have to endure such significant and potentially dangerous problems with their vehicles. Thank you for your attention to this matter. I look forward to your prompt action and response.

I am writing to bring to your attention a critical safety issue with my 2019 Kia Optima SX 2.0 GDI Turbo, which has accumulated approximately 103,000 miles. This vehicle has recently developed several serious problems that I believe pose significant risks to both my safety and the safety of other road users. Firstly, my Kia Optima has been burning an excessive amount of oil. Specifically, it consumes over 5 quarts of oil within just 2,000 miles of driving. Despite thorough inspections, even from Kia Dealers there are no visible oil leaks, making this issue even more perplexing and concerning. Moreover, the vehicle has begun to shake violently while driving on the highway, which has led to a substantial loss of power in the middle of traffic. This unpredictable loss of power is extremely dangerous, especially at high speeds, as it compromises my ability to maintain control of the vehicle and poses a significant hazard to other motorists. Additionally, the car now emits a loud knocking noise, which appears to be related to the engine's internal components. This issue further exacerbates the vehicle's performance problems and raises serious questions about its reliability and safety. I urge the NHTSA to investigate these issues promptly. The problems I am experiencing are not isolated and may affect other Kia Optima owners, potentially leading to widespread safety risks. I believe it is crucial to determine if there is a manufacturing defect or other underlying cause that needs to be addressed to prevent accidents and ensure the safety of all Kia Optima drivers. Thank you for your attention to this matter. I am hopeful that the NHTSA will take immediate action to investigate these serious safety concerns and provide a resolution to protect both myself and others.

My paint job is peeling away. I can not even wash my car with out it flicking off.

The skid plate under the vehicle has two pieces. The main larger piece and a small piece that comes off to change the oil. The screws used to hold up the smaller part of the skid plate tend to puncture the oil pan because one of the screws holding the skid plate is directly underneath the oil pan. If people are unaware of the oil being gone it can seize the motor and stall the vehicle. After researching and looking at different forums, this is a common issue that takes place.

Two thefts of my 2019 Kia Optima in less than one year; 9/12/2021 and 7/30/2022 due to Kia's negligence in fixing a very obvious security flaw and lack of engine immobilizer. I have spent approximately $2,500 of my own money between insurance deductibles and replacing items that were stolen from my vehicle in addition to the actual vehicle theft. The thefts caused over $13,000 of damage between the two claims, and surely have depreciated the value of my car significantly. Thousands of Kia customers are negatively affected by this negligence, and we are being punished and violated for owning compromised vehicles. I feel incredibly unsafe driving my vehicle anywhere knowing full well it could be stolen at any moment.

I HAVE A 2019 KIA OPTIMA. IN DECEMBER I WAS GOING UP A HILL AND THE VEHICLE STARTED VIOLENTLY SHAKING. I WAS PRESSING ON THE GAS AND NOT GOING ANYWHERE. I HAD TO PUT IT IN REVERSE TO BACK DOWN 2 RODS TO GET BACK TO MY DRIVEWAY. HAD IT TOWED TO DEALER AND THEY SAID THEY COULD NOT FIGURE OUT WHAT WAS WRONG. IT WAS NOT SHOWING ANY "CODES". THEN ON 02/26/2020 THE CHECK ENGINE LIGHT CAME ON. HAD IT TOWED TO KIA DEALER AND THEY SAID IT WAS SHOWING A BUNCH OF CODES. THEY SAID THEY CLEANED THE "KNOCKER" AND WAS COMMUNICATING WITH THE TECH LINE AND WAS TOLD TO CLEAR DATA AND RELEARN SYSTEM. ONCE THEY DID THAT THE CHECK ENGINE LIGHT WENT AWAY AND NO MORE CODES DISPLAYED. ON 03/07/2020 THE CHECK ENGINE LIGHT CAME ON AT NIGHT. DEALER WAS CLOSED BY THEN AND THEY ARE CLOSED ON SUNDAY.

Brought vehicle in for Recall-SC340 Theta II 2.4L GDI ECM S/W Upgrade. After service was performed I took my vehicle back home and noticed that my down shifting was different, jolty and clunky. Prior to the upgrade my vehicle shifted flawlessly. Took my vehicle back in to have them check it out and they told me that they couldn't feel it and that the upgrade wouldn't cause that. Called Kia Corporate and filed a complaint.

On March 2022 Forward Collision Warning System, Blind Spot Warning System, ABS braking System and other systems associated with a bad passenger rear wheel sensor not working. On March 17, 2022 rear passenger wheel sensor repaired under warranty by local Kia Dealer. In September 2023 same issue with the above warning systems occurs with only another 2,000 miles on car after previous repair. Local Kia dealer states both rear wheel sensors need to be replaced. Kia dealer states vehicle is no longer under warranty and will cost in excess of $800 to repair. After checking similar complaints online, I believe there is an inherit defect with this type of vehicle's wheel sensors and a recall is needed to enforce Kia to stand by their product and ensure the safety of the vehicle and their customers.

The contact stated that his wife was driving at approximately 35 MPH when she heard an abnormal "booming" sound from the passenger side rear tire. The contact stated that his wife pulled into a parking lot and called the contact. The contact stated that when the tread delaminated from the tire part of the rear passenger wheel well was cracked by the debris. The contact was able to replace the damaged tire with the spare and drove the vehicle back to the same tire dealer. The contact stated that the dealer advised that the tire manufacturer would be contacted because the dealer reported that other customers were having tread separation failures with the same tire line. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate vehicle failure mileage was 47,800 and the tire failure mileage was approximately 10,000.

Dear National Highway Transportation Safety Administration, I am writing to express my extreme dissatisfaction and concern regarding the Goodyear Assurance Weather Ready tires, size 235/45R18, installed on my 2019 Kia Optima SX. These tires have proven to be defective, failing to meet the standards of safety and durability promised by Goodyear. I would like Goodyear to refund for the defective tires! Despite being well within the mileage limit of the 60,000-mile warranty, Goodyear has refused to stand by their product. Instead, they have absurdly attempted to shift the blame onto me, suggesting that frequent alignments are necessary at every oil change. This is not only an inconvenience but also an unjustifiable expense for a supposedly high-quality product.I have diligently maintained my vehicle and have documentation to support the fact that the tires are defective. However, Goodyear has shown a complete disregard for customer satisfaction and safety by failing to address this issue adequately. I urge the National Highway Transportation Safety Administration to investigate this matter promptly and take appropriate action against Goodyear for their negligence and failure to uphold their warranty obligations. Plus to have the tires taken off the market as they put myself and my families lives at risk. Consumers deserve better than to be burdened with faulty products and dismissive customer service.

I have had my AC have 4 problems now and continue to have different problems since I bought the car a little over 6 mo ago. KIA is a pain and I'm constantly taking my vehicle in. The first time it wasn't major, the second time it was something electrical with the AC that tore apart my whole dashboard. Now I have a mold and mildew smell in my car and water leaking excessively under my car. My daughter who is 5 yrs old hasn't had ac for multiple weeks and now we are inhaling mold and mildew. I changed the cabin filter that was in the car and it had water stains all over it. This is a safety concern for the health of me and my child and I want things made right.

I was just driving then noticed lack of acceleration and the engine light flashing. Loosing acceleration mid driving posed a great safety risk because no other drivers would know the issue I was experiencing and risked causing an accident. The vehicle was taken for a fault code reading which indicated a knock sensor code, later it was inspected at the dealership who confirmed an ECU issue. The police or insurance have not inspected the vehicle for this particular issue.

While at the dealer service department for failed A/C system, we questioned the excessive oil consumption and engine replacement. We were told they found nothing wrong. Having to top off oil every 1,000 miles or so. It does not make it to the next oil change before the light comes on. No oil leaks. Mechanic said known problem with this engine. Most recently the starter went bad, alternator, and battery. Replaced with a second brand new battery and car won't start again. Dash is lighting up erratically, new battery dead. As if something is drawing all power and draining brand new batteries. This car has a little over 86,000 miles and one thing after another is failing. The car lost power and power steering in a curve leaving us in a dangerous situation after replacing the starter. Dash lighting up erratically with front end collision warning message on the display. We had it towed to our residence which our auto insurance reimbursed us for. Replaced alternator and battery yesterday, and the car lost all power again turning back onto our street, again with the Dash lighting up erratically.

My 2019 KIA optima with 116,021 odometer on mileage. Stop in the middle of High Volume Traffic , Because of Software Issues , I suspect . All Forward Collision Warning Detection , Also Rear Collision Warning Alerted on dashboard!!! Which Causes my Car to stop in the middle of Traffic Completely shut down. I was able to get my vehicle towed to KIA West Dealership Located in lithia Springs GA . I requested a diagnostic test and was informed by my service advisor and service manager that my vehicle has a burned out wire located in the left right rear sensors radar assembly, bumper area . Which will eventually have caused a fire or actually already did, I asked how did it happen? I was told it just simply burnt out. !!!! I was told the assembly box junction box needed to be replaced, which I agreed at that moment in order to diagnose the vehicle. Second the electrical problem was revealed, which is the big problem now currently for 1 , the vehicle is not safe for a midsize sedan on public roads and highways the if this make and model car causes random fires. secondly the parts very expensive and suspicious. I’m currently still doing my investigation. Unfortunately I had to agree for the sensors to be replaced and fixed because personal reasons I need my vehicle to get back-and-forth to work, etc.. I’ve been in contact consumer regional services, No one is able to find a recall with my Vin number the car never been in a accident ever. I have a picture of the hazardous burned out wire the technician showed me as well. As they claimed randomly caught fire.

I like kids however I purchased a Kia used in 2021, I started to notice that all consumption was going out fast before oil changes was due. I still have this ongoing problem but they say there's no recall on these GDI motors however other people I see informs or experiencing the same issues. I now have to try to get an appointment with Kia for an oil change before it's time for the oil change and to do a oil consumption test and then hopefully the main factors or kia will replace this motor even though there's no warranty on the car. I might also have a issue with the front collision feature because I have been noticing in the past few weeks that this feature comes on even when there's no car in front of me it will start to break however it says that my car is not a part of a software upgrade so I got to ask them about that as well. There is definitely a issue with the GDI motors and Kia really needs to recall them all and replace the motors it should not burn all the way that it does I've never had any car of any brand or manufacturer burn oil the way that this car is burning oil. I cannot financially afford to go out here and trade this car in and get another car with the type of payment that I have for this car since I had my bank finances car.

Dear National Highway Traffic Safety Administration, I am writing to file a formal complaint regarding numerous premature defects in my 2019 Kia Optima, which have led to serious safety hazards and compromised driving conditions. Firstly, the premature valve cover gasket leaking has resulted in dangerous fumes infiltrating the cabin, posing a significant risk to my health and safety as well as that of any passengers. This issue has not only caused discomfort but also raised concerns about potential long-term health effects. Additionally, the premature turbo gasket leaking is a further cause for alarm. Not only does this compromise the vehicle's performance and efficiency, but it also presents a potential fire hazard, particularly if the leaking oil comes into contact with hot engine components. Furthermore, the premature defect of the axle shafts and axle boots is a critical safety issue. This compromises the vehicle's stability and handling, increasing the risk of accidents and potential loss of control while driving. Moreover, the premature engine knocking and abnormal shaking and lag are indicative of underlying mechanical issues that significantly impact the vehicle's drivability and safety. Engine knocking can be a precursor to more severe internal damage, while abnormal shaking and lag compromise the vehicle's responsiveness, especially in critical situations such as merging onto highways or overtaking. These issues collectively present a clear pattern of premature defects that pose significant safety risks to both myself and other road users. As such, I urge you to investigate these matters thoroughly and take appropriate action to ensure the safety and well-being of Kia Optima owners. I look forward to your prompt attention to this matter and a swift resolution to address these critical safety concerns.

Dear National Highway Transportation Safety Administration, I am writing to bring to your attention a grave safety concern regarding my 2019 Kia Optima SX. Despite diligent maintenance and care, my vehicle has experienced persistent alignment issues, particularly on the right side. Additionally, I have encountered premature axle shaft and axle boot failures, all of which have occurred well before reaching 60,000 miles. These issues have not only posed a significant financial burden but have also jeopardized the safety of myself and other road users. The repeated alignment problems have resulted in the rapid deterioration of tires, leading to baldness within a month of replacement, creating a hazardous driving condition and increasing the risk of accidents. The premature failure of axle shafts and boots is unacceptable for a vehicle of this age and mileage. Such failures not only compromise the vehicle’s performance but also raise serious concerns about the overall quality and safety standards of the Kia Optima SX. I urge the National Highway Transportation Safety Administration to conduct a thorough investigation into these recurring issues affecting the 2019 Kia Optima SX model. Immediate action is necessary to ensure the safety of consumers and to hold Kia accountable for any design or manufacturing defects contributing to these alarming problems.

Since I have had the vehicle I have had to have multiple Spark Plugs and Engine Coils replaced, literally every 4-6 months. One diagnosis said there was a problem with the motor, when I told Kia, they did not come back with the same diagnosis, well they sort of did, but did not noter it as an issue. Also, my car burns oil way too fast. I'm having to put in 2-23 quarts every 2-3 weeks. I have been told that the GDI motors are the culprit for this. Have even heard Hyundai had a enough complaints and has recalled the motor, but Kia did not, so we are still running around here paying excessive amounts on oil and repairs.

ABS light came on for no apparent reason and took car to Kia dealership and was told it needs ABS Issue: “Your car is going to need an ABS Actuator, this controls how the ABS modulates the brakes when under dangerous braking conditions so that your brakes don't lock up..$2676.56 just for that repair if you'd like us to replace it” and I searched online and do see that some 2019 Kia models had a recall for this very issue, but my VIN is not showing up as affected. The lights came on about 6 mos ago, cleared and then came back on again. Car is at Moritz KIa in FW, TX right now.

I just think theres some sort of a tech issue with my electronic dashboard. My passenger seatbelt sign goes on and beeps incessantly when there is no passenger in the seat. My caution alert button comes on saying I have low tire pressure when it’s only one number less than all the other tires. My oil change reminder never comes on. Today I was driving normally and the car in front of me barely tapped their breaks (and I was not close to them at all) and the collision alert started beeping. My car randomly gets cold and the AC smells like it’s on, but it’s not (the button isn't lit nor did I turn it on) It normally doesn’t allow me to turn the outside air button on/off. Like in the winter when it’s freezing outside and I wasn’t to press the button to only circulate the inside air in the car, it doesn’t allow me and I have to freeze and be uncomfortable in my own car.

I WAS DRIVING UP A HILL AND AS I REACHED THE TOP OF THE INCLINE, MY CAR STOPPED ACCELERATING. I THEN ATTEMPTED TO USE MY BRAKES AND I BARELY TAPPED THEM, BUT THEY REACTED AS IF I SLAMMED ON MY BREAKS. I TOOK MY FOOT OFF OF THE BRAKES AND I BEGAN ROLLING BACKWARDS EVEN THOUGH MY CAR WAS STILL IN DRIVE. MY BRAKES WERE THEN LOCKED, I PUT MY CAR IN PARK AND THEN TURNED OFF & THEN BACK ON MY CAR WITHOUT REMOVING THE KEY. I THEN PUT MY CAR BACK INTO DRIVE, HOWEVER, MY GAS PEDAL WAS STILL NOT WORKING. I THEN TURNED MY CAR OFF AGAIN, REMOVED THE KEY, PUT THE KEY BACK, THEN RESTARTED AND WENT BACK INTO DRIVE AND IT BEGAN TO WORK AGAIN. THERE WAS NOT AN ISSUE AFTER THAT.

I PURCHASED ON MY 2019 KIA OPTIMA ON 6/19. AND SINCE THEN OFF AND ON THE CAR HAS EXPERIENCE INTERMITTENT STARTING ISSUES. NOW I HAVE TAKEN THE CAR TO TWO DIFFERENT DEALERS AND NEITHER ONE CAN FIND THE PROBLEM. WHEN PRESSING THE STOP/START BUTTON THE CAR WOULD HESITATE TO START NO LIGHTS OR CODES ARE STORED IN THE COMPUTER. I HAVE CONTACTED KIA ABOUT THE ISSUE ALL I WAS EVER TOLD WAS TAKE IT TO THE DEALER AND LET THEM INSPECT IT. THE DEALER WOULD RESET AND UPDATE FIRMWARE. THAT WOULD LAST FOR A MINUTE BUT EVENTUALLY THE CAR WOULD GO BACK INTO THE SAME THING OF HESITATING. THE CAR HAS BEEN INTO THE DEALERSHIP MULTIPLE TIMES FOR THE SAME ISSUE KIA HAS OPENED CASE AFTER CASE BUT NO SOLUTION. THE CAR IS CONSIDERED A LEMON BY STATE STATUES. NOT ONE TIME HAS KIA OFFERED TO TAKE THE VEHICLE THE ONLY THING I'M TOLD THAT IF IT HAPPENS AGAIN BRING IT BACK. I WOULD SPEND MORE AND MILES TAKING THE CAR TO THE DEALERSHIP. THERE IS ALSO AN ISSUE WITH THE WHEEL ALIGNMENT THE LEFT REAR WHEEL ALWAYS NEED TO BE ALIGNED I'M NOT SURE WHY BUT WHEN I TAKE THE CAR FOR AN ALIGNMENT THAT WHEEL IS ALWAYS OUT OF SPECS.
