2019 Kia Optima Owner Complaints

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 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 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.

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.

The engine of vehicle repeatedly failed, causing the vehicle to stall while driving, which posed a serious risk to my safety and others on the road. The vehicle had approximately 65,000 miles and was maintained routinely and on schedule. The failure first occurred before November 18, 2025, when I reported stalling issues to Kia authorized service & parts. The vehicle was returned as “fixed” on December 12, 2025, but the engine stalled again during normal operation. The vehicle was returned to Kia authorized service & parts multiple times (December 12, December 18, December 23, January 9, January 12, 2026, and March 4, 2026), with repeated assurances that it had been repaired. Each time, the car continued to stall, including during a test drive at Subaru, demonstrating that the failure persisted despite repeated dealer intervention. The stalling created a significant hazard, as the car could lose power while on public roads, including highways, potentially leading to accidents. There were no consistent warning lights or messages prior to the engine stalling; the first symptom was intermittent loss of power while driving. The failure has been reproduced and observed by multiple service personnel at Kia authorized service & parts and by Subaru during the trade-in test drive. The component(s) causing the failure were inspected by Kia authorized service & parts staff, but no effective repair was made. Documentation of repair orders and dealer inspections is available for review.

The vehicle experienced a sudden engine failure one day after undergoing a manufacturer emissions/service campaign at an authorized dealership. Prior to service, the vehicle operated normally with no warning lights, knocking, or drivability issues. After the failure, the dealership denied coverage and declined to inspect the engine oil. The vehicle was towed for an independent inspection, which found metal shavings in the engine oil, indicating internal mechanical engine failure. The sudden failure created a safety risk due to unexpected loss of engine function. The issue has been confirmed by an independent service center and the vehicle remains available for inspection. No warning lamps or symptoms were present prior to the failure.

The contact owns a 2019 Kia Optima. The contact stated that while the vehicle was parked, there was sputtering sound coming from the engine compartment, with the check engine warning light illuminated. The contact stated that while driving at an undisclosed speed, the vehicle was running rough. The vehicle was taken to the independent mechanic where it was diagnosed with a cylinder misfire and burned spark plug, and that there was oil inside the cylinder and on the spark plug. The contact was informed that the parts needed to be replaced. The vehicle was repaired but the failure reoccurred months later. The vehicle was taken back to the same independent mechanic where it was diagnosed with oil consumption, oil intrusion into the firing chamber, and that another spark plug needed to be replaced. The vehicle was repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 112,000.

I purchased this vehicle on [XXX], with approximately 170,150 miles. On [XXX], during a routine oil change at approximately 172,636 miles, it was discovered that the engine had no oil present. Shortly afterward, the oil warning light began flickering intermittently while driving. On November 4, 2025, at approximately 175,495 miles, a certified mechanic again confirmed that there was no oil present in the engine. At no point were there visible external oil leaks, indicating excessive internal oil consumption. This condition creates a serious safety risk, as sudden engine failure while driving could lead to loss of power, stalling, or accidents. Based on my experience and publicly known issues involving Kia engines, this appears to be a systemic defect rather than normal wear. I am requesting that NHTSA document and review this issue as a potential safety defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
