2019 Kia Optima

Car smelled of what seemed like motor oil while driving. Parked, saw white smoke, and confirmed an engine fire. I was clearly in life threatening danger, especially with a full tank of gas. Fire developed rapidly into a roaring blaze. Entire front of car melted. Car is currently being investigated by manufacturer and cause is unknown. No warning lamps illuminated.

On XXX, Towbin Kia Service (Henderson, NV) officially diagnosed my 2019 Kia Optima (VIN: [XXX], Mileage: 118,325) with a critical component failure: "LOW PRESSURE FUEL PUMP IS LEAKING FROM TOP HAT" (Invoice #XXX). Despite documenting a severe, volatile raw fuel leak that presents an immediate fire and explosion hazard, the dealership refused to keep the vehicle. They explicitly released this active safety hazard back to me. The service department even arranged a third-party Lyft ride to transport my children and me to the dealership to pick up the leaking car and force us to drive it home. The vehicle is currently parked outside my residence, actively leaking raw fuel and filling the cabin with toxic gas fumes. It is entirely un-driveable and a public safety threat. Kia Corporate must immediately bypass standard dealership timelines, authorize a flatbed tow to retrieve this fire hazard, and directly provide an emergency corporate rental vehicle line (Enterprise/Hertz) for my family's safety today.

The vehicle experienced a sudden and severe loss of engine power while being driven on the interstate at highway speeds. The vehicle lost the ability to accelerate normally beyond approximately 60 mph, the Check Engine Light began flashing rapidly, and the vehicle entered “Limp Home Mode.” This sudden loss of power occurred in heavy traffic and created an immediate risk of a high-speed rear-end collision. The vehicle was subsequently inspected by an authorized Kia dealership service center. Diagnostic testing confirmed DTC P1326 (Knock Sensor Detection System). The dealership performed the manufacturer’s Bearing Clearance Test (BCT), and the dealership paperwork documents a “NO PASS BCT” result. The dealership paperwork also documents that Service Campaign SC340 (Theta II 2.4L GDI ECM Software Upgrade) was performed on the vehicle. Despite the documented P1326 condition and the manufacturer’s “NO PASS BCT” result, the dealership is refusing to provide the engine replacement as a covered repair and has instead quoted approximately $9,000 for the engine replacement. I am requesting that NHTSA review this matter because the vehicle experienced a sudden loss of power at highway speeds, followed by a documented “NO PASS BCT” result from the manufacturer’s diagnostic procedure. The vehicle remains an unresolved safety concern. I am also requesting review of whether Kia is properly applying the applicable P1326/BCT engine-replacement procedure and associated coverage to this vehicle. The vehicle and all diagnostic and service paperwork are available for inspection upon request.

On December 26, 2023, this vehicle received a complete engine assembly replacement at an authorized dealership under a manufacturer warranty repair order. Following the engine overhaul, the vehicle developed a severe, raw gasoline smell entering the passenger cabin through the climate control AC vents while sitting at an idle.The vehicle was brought back to Kia Store East on September 10, 2026, specifically to report this volatile safety issue. On September 17, 2026, the dealership technician explicitly duplicated and confirmed the raw fuel odor coming from the engine area in writing. Despite confirming the gasoline smell, the dealership is refusing to perform a manual high-pressure fuel system pressure-drop test to isolate the physical vapor leak. Instead, they have listed a high-pressure Fuel Pipe Assembly (Part # 35305 2GGA0) on a customer-pay estimate paired with an unrelated $1,819.12 timing cover oil seal repair.The dealership is claiming the failure is out of warranty and is holding the vehicle while forcing daily rental car fees onto me, refusing to isolate the active fuel leak unless I authorize the out-of-pocket repair. The vehicle currently sits un-repaired at the dealership as an active cabin fire and occupant chemical exposure hazard that the manufacturer and dealer refuse to properly diagnose or cover under repair workmanship guidelines.

My car was parked when my Kia Optima Panoramic sunroof exploded. It was between 8:00-8:30 a.m. Friday XXX. It sounded like an explosion. I was sleeping and the explosion woke me up. The sunroof was closed and the car was parked. We r not aware of anything coming in contact with the sunroof. Actually the sunroof exploded from inside the car. The broken glass was pointed upwards. I’m concerned that this is a serious hazard if it occurs while I was driving it would have caused a serious accident or even a death. I notified KIA Customer Care Center. XXX Case # XXX. I also sent them a letter concerning the event with photos. I have found information that other reported KIA panoramic sunroof failures and concerned that this may be part of a bigger problem. Customer Care rep [XXX] told me to take the car to a dealer. Cannot see me for 3 weeks and charge $209.99. Called customer care again talked to Risha, told me not to take to dealer and not pay anything. Then wait for someone to get back to me. That was XXX. If I haven’t had any contact from Kia I’m supposed to call back XXX. Still waiting. I am asking NHTSA to document this incident and review whether there is a safety- related defect or pattern involving panoramic sunroofs on KIA vehicles, including the 2019 KIA OPTIMA. Car is 7 years olds an 72,400 mi. The warranty is 5yrs -60,000. Please include this complaint in NHTSA’s records concerning the 2019 Kia Optima and Panoramic sunroof failures. I authorized NHTSA to share my complaint and identifying vehicle information with Kia if that is necessary to investigate the issue.

While driving, my vehicle suddenly began shuddering and shaking. The vehicle lost power and would not accelerate properly. I had to press the brake pedal unusually hard. After parking, the vehicle would not move properly in reverse or drive. I turned the vehicle off and restarted it, and it moved only a short distance before shuddering again and losing power. The engine was making a loud buzzing or scooter-like sound. The vehicle became undrivable and had to be parked. I am concerned about a potential safety defect involving sudden loss of power while driving.

The contact owns a 2019 Kia Optima. The contact stated that while driving at various speeds on two occasions, the vehicle lost power with the check engine warning light illuminated. The vehicle was driven over to the side of the road and then towed to the dealer twice; however, the failure was not duplicated on the first visit. During the second visit, the vehicle was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 146,000.

Strong smell of gasoline from the rear of the vehicle started around 60,000 miles . Car dealership said it’s normal but I don’t smell other cars like this

Unknown was just driving to go to my husband to work and it came on when I was coming back home and when I went to pick my husband up from work and was stopped at a stop sign the lights came back on

Oil is needing added on a weekly basis to keep up with how much the engine is burning, Spark Plugs and Coils have been changed excessively, the dealership says we may end up being covered by a recall but the engine needs to completely fail first.

The paint on my car is delaminating. There are bubbles throughout the car and a few huge bubbles have popped and now the bare body is visible. I have called Kia corporate and they have denied my request to repaint the car. They are telling me that the is a three-year warranty on the paint. My car is only seven years old, and the paint should not peeling/bubbling. I have taken my car to a collision center, and they believe it is caused by a defective manufacturer paint. After looking online, it is a nationwide chronic problem with snow white pearl. Kia is totally aware of this and doesn't want to address the problem. I do know there are many lawsuits against Kia for this particular problem. I am seeking help to get this resolved. Pictures attached.

I was driving down the highway when I kinda noticed speed changed. ABS lights, foreword collision light, and rear end lights, so I turned around went back home. I rarely drive my car and I never had any problems with it. I purshased it brand new.

I am reporting a recurring safety hazard involving my 2019 Kia Optima following a repair for diagnostic code P064A (Fuel Pump Control Module). Despite the dealership attempting to repair the fuel system, the vehicle remains in a 'limp mode' state. While driving, the vehicle began shaking violently and lost significant power, refusing to accelerate above 50 mph. This creates an immediate safety risk, as the vehicle cannot maintain highway speeds or safely merge, increasing the danger of a rear-end collision. The P064A code and subsequent 'limp mode' symptoms persist even after professional service. I am concerned that the existing Kia warranty extensions (such as WTY028 for the low-pressure fuel pump) or current repair procedures are insufficient to resolve this underlying mechanical/electronic failure, leaving the vehicle unpredictable and hazardous to operate in traffic.

Engine failure, metal leaking into oil which caused engine to fail

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.

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.
