ENGINE
The dealer stated my engine repair is not covered under the recall/warranty because an ECU software update was not performed. I was quoted $8500 for engine replacement (Long block). I have owned this vehicle for 2 months, going on 3. I am requesting a review of whether this vehicle qualifies for any engine recall or safety-related warranty coverage, as the explanation provided by the dealership appears inconsistent.

ELECTRICAL SYSTEM, AIR BAGS, STEERING
The horn stops working, steering heat stop working, control functions and air bag warning. I changed the clock spring and it fixed all those issues the first time but within 6 months all those issues happened again. Is there something more wrong?

ENGINE
We were told by the mechanic that the engine was locked up after the car refused to drive faster than approximately 23 mph. We had to have the car towed from Boone, NC which was about 200 miles. The car is at our house and is available for inspection upon request. I have made repeated calls to different Kia dealers asking for a call back to assist me with direction but there will never be a returned phone call. As far as I know, there has been no inspection of the engine or vehicle.

EXTERIOR LIGHTING
The low beam headlight assembly failed on my 2019 Kia Optima LX with no prior warning, while the high beams and LED daytime running lights continue to function normally, indicating an isolated component failure within the assembly. Notably, the headlight assembly shows no physical damage whatsoever, and both independent licensed repair facilities that inspected the vehicle were unable to identify or repair any specific failed component — both independently concluded that a full assembly replacement is necessary. The fact that no specific component could be identified as the cause, combined with the absence of any physical damage, suggests this may be an internal failure not consistent with typical wear and tear. Prior to complete failure, the low beam would intermittently illuminate and then cut off unexpectedly during normal operation, which was the only symptom present before the headlight stopped functioning entirely. This creates a genuine safety concern as low beams are the primary source of nighttime illumination and cannot be substituted with high beams in normal traffic conditions. The failure occurred suddenly during normal nighttime driving and could not be fixed with bulb or pigtail replacement as both were in good condition. The vehicle and component remain available for inspection upon request.

ENGINE, ELECTRICAL SYSTEM
Drove roughly an hour from Roseville MI to Temperance MI. Car was fine. No issues on the drive. Gauges were all fine. Got to my friend’s house and took my stuff inside. Came back out immediately and saw dark smoke now coming from the hood. Attempted to open, but couldn't unlatch the hood after it was popped. Saw flames and called 911. Entire car burned down to the back seats. Car seat, Reading glasses and personal items destroyed. Fire fighters put it out and police took report. KIA after review states they dont know why it happened. Also has taken forever and not offered to compensate me in any way shape or form. Received their “findings” a day ago, April 30. Date of fire was Feb 11th 2026.

ELECTRICAL SYSTEM, ENGINE
A issue with the Valve cover gasket leaking into the engine causing a misfire. Making the car suddenly stop while driving which is very unsafe. I took the car to the dealership and they want to charge me for the repairs. I have 2 kia optima hybrid and both cars have the same issue around the same mileage. There were no warning lights during the time it was at the shop. However one day the check engine light did come on and the OBD code P1326 came up. When I took it to the shop the check engine light disappeared and the dealership said they will not check my engine unless they see the code on their end. I believe later down the line the engine will stall out and it should be fixed now while under warranty. However I received no help from the dealership unless I am willing to pay upfront. In addition to this there are electrical issues the front seats aren't moving immediately when the button is pressed. The steering wheel buttons barely work along with the radio. This is a huge problem that needs to be fixed.

ENGINE, POWER TRAIN
Sudden engine failure while driving with no warning. Vehicle began jerking, shaking, and losing power. RPMs dropped unexpectedly and the engine stalled intermittently. Multiple misfire codes were present (cylinders 1, 3, and 4), and the engine was found to have low or no compression in cylinder 1. The condition rapidly worsened to near complete engine failure. The vehicle was operating normally prior to this incident. This failure is consistent with known Kia engine defects involving internal engine damage, including rod bearing failure. This is a safety concern due to sudden loss of power while driving.

ENGINE
The contact owns a 2013 Kia Optima. The contact stated while driving 75 MPH, the vehicle went into LIMP Mode and failed to exceed 60 MPH. The check engine warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the knock sensor and the harness had failed and needed to be replaced. The vehicle was repaired; however, the failure recurred on several occasions, and the vehicle was driven or towed to the dealer as needed. The dealer cleared the diagnostic trouble codes and informed the contact that a recall repair would not be completed unless the engine made loud knocking sounds or seized. The contact stated that while driving at an undisclosed speed, the engine made an abnormally loud sound and seized. The vehicle was towed to the residence. The vehicle was then towed to the dealer, where the contact was informed that the engine was not eligible for replacement due to a lack of maintenance records because the contact did not have all the oil change service records available. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 297,000.

ENGINE
2018 Kia Optima LX, 2.4L GDI Theta II engine. Approximately 128,000 miles. Reporting severe internal oil consumption that has progressed to engine misfire and shaking, consistent with late-stage Theta II connecting rod bearing failure. The vehicle is now unsafe to drive and has been parked. Timeline: Purchased as a Certified Pre-Owned vehicle in December 2021. Excessive oil consumption began shortly after purchase. For approximately 4.5 years I have added about 1 quart of oil every 2 weeks to keep the engine from running dry. No external leaks have ever been found by any mechanic. Multiple independent mechanics attempted diagnosis and repair over this period. None resolved the issue. The vehicle has now developed a pronounced shake and apparent engine misfire, the textbook progression to rod bearing failure documented in NHTSA investigation PE19-004 and prior recalls/campaigns 17V-224, SC147, and SC172. Safety concerns: Sudden engine seizure or stall at highway speed creates a serious crash risk for me and surrounding traffic. Theta II 2.4L GDI rod bearing failure has been associated with under-hood fires. The defect develops gradually with no warning to the driver beyond elevated oil consumption, which is frequently dismissed as normal until catastrophic failure occurs. I am filing this complaint to document the failure and to add to NHTSA's data on the Theta II GDI 2.4L engine in 2018–2019 Optimas. This model year was excluded from the original 2017 recall but is included in the Hyundai and Kia Engine Litigation class settlement and the lifetime engine warranty extension. My vehicle's symptoms match the defect pattern exactly. I will pursue warranty engine replacement, but I want this safety failure on the federal record regardless of how Kia responds.

STEERING, UNKNOWN OR OTHER, SUSPENSION
While driving my KIA Optima on the interstate the rear subframe suffered catastrophic structural failure, resulting in the steering wheel going out of alignment, the rear passenger side wheel tilting with the bottom of the tire being far out compared to the top. This resulted in the rear of the vehicle swaying side to side and being difficult to maintain in a straight path. This vehicle was previously serviced under KIA Campaign SC141 (internal subframe corrosion) at Griffin KIA on April 27, 2017. Despite this safety remedy being performed the subframe rotted through and snapped. This is a remedy failure. The anti-corrosion was applied by the manufacturer failed to prevent the exact structural failure it was designed to mitigate. I have physical evidence (Repair Order #92144) proving the remedy was performed and photographic/video evidence of the subsequent structural break. The manufacturer (KIA) has denied assistance, claiming the failure is "unrelated" to the corrosion campaign despite the part being the exact component covered by the campaign." SC141 involved the inject of wax into the metal components of the subframe of the vehicle and was KIA's response to the NHSTA's concerns about the metal components of their vehicles being unable to withstand salt in the Rust Belt states. The campaign only was for the vehicles in the rust belt states. KIA was very aware this was a safety issue and attempted to avoid a recall by issuing this campaign. The campaign failed and as a result my life was put at risk. I asked KIA for a good will repair of the rusted subframe but they refuse indicating the believe the part that clearly broke due to rust is unrelated to the safety campaign. Several of their employees stated it was very clear the part broke due to rust with one indicating he had a list of rusted parts needing replaced. I'd like the NHTSA to review this failed campaign and ensure the safety of all vehicles relying on this failed safety measure.

ENGINE, FUEL/PROPULSION SYSTEM
My vehicle burns oil too quickly. I schedule my regular oil change based on the feedback from the auto repair shop. During my last oil change he said I practically had no oil left, but it has been less than 5,000 miles since my previous oil change. The tech informed me he's seen this happen a lot within Kia's including the optima that I currently drive. Fast forward a few months i noticed my oil light illuminate for a moment and immediately turn off. I still want to get it checked out just in case so i brought it back to the same shop. They informed me my oil was very low even though, but I still have another 1,500 miles before my next due oil change. He looked around and confirmed there were no leaks or damage that would affect the consumption rate. He highly recommended me look to see if there were any recalls on my specific model of vehicle that would warrant both an explanation and reason for replacement. In the meantime he topped off my oil and i was all good to go.

STRUCTURE:BODY
I am submitting a defect complaint regarding the paint on my vehicle, which has been progressively deteriorating. The issue begins as small bubbles in the paint, which eventually lead to peeling and complete paint loss in affected areas. This condition is currently present on the trunk, roof, and rear sides of the vehicle, and early signs are now appearing on the hood. This defect is more than cosmetic. As the paint peels, it exposes the underlying metal panels to environmental elements, increasing the risk of corrosion and rust. Over time, this can compromise the structural integrity of the vehicle. Additionally, significant peeling—particularly on surfaces like the roof or hood—can create glare or release debris, posing a potential safety hazard and distraction to both myself and surrounding drivers. I initially brought this issue to a Kia dealership, where the manager advised me to contact Kia Customer Affairs. Upon doing so, I was informed that the issue falls outside the warranty timeframe. However, after speaking with other Kia owners experiencing similar problems—especially with the same paint color—it appears this may be a widespread manufacturing defect rather than normal wear and tear. Furthermore, a professional paint specialist evaluated the condition and indicated that the bubbling and peeling are consistent with poor paint adhesion or a defective clear coat/mid-coat application during manufacturing.
