I have replaced the headlights in my 2011 Kia Optima multiple times but no matter what without the brights on, the road is not at all illuminated making it impossible to see at night. When you look at the car head on the lights look as if they would be incredibly bright, but I believe due to faulty reflective lining on the interior of the headlight housing, even though the bulb may shine brightly, it does not get reflected properly onto the surface of the road causing serious safety concerns.
NHTSA complaint #11741618 — an unverified report by a vehicle owner.
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.

The engine is a problem and all I’m ever told us “ this vehicle is know to have engine problems. This is dangerous to have in the road. Kia is aware of this. Why sale the vehicle knowing this and not disclosing this info to the consumer upon purchase. There is no truth in lending. It’s plain sight robbery. What if I’m far from home and stranded because vehicle set fire or broke down in hazardous condition weather. I constantly needing oil changes because of this engine. The dealership is aware. They tell me to trade it in or get rid of it because it’s going to go for a fact. I’ve never missed oil changes. I put oil every time the oil indicator light comes on. Now for the 3rd time the check engine light is on. 2 times for misfire code. The vehicle engine holds sludge no matter how much you get oil changes. The mechanic told me this year make and model is known for this very fact. I want my money back. Kelly blue book don’t give enough. I was scammed into this car but I managed to pay it off. A car the sales person scammed me and wouldn’t take the vehicle back. I complained to the general manager. They always act like he wasn’t available. They kept claiming new ones started. After almost a year of those games I had to move and the case never got solved. But even when I complained their maintenance person stole my rims. They told me prove it. Just all bad experience. I just want my money. Even if they gave me another engine. It’s still going to be the same problem. A bad engine. 2016 Kia optima’s should not have been continuously sold with them knowing it has bad engines. Even the headlights don’t work. Very dim. Car smells like burning fumes when driving. Please please help. This isn’t fair lending practice. People trust them and they are dishonest sellers.

I’ve gotten my vehicle fixed four times now thinking it was an electrical issue, not aware of the recall. Did my research this fifth time when my brake lights completely went out and smoke at some point in times come through my air-conditioning. I’ve spent more money trying to fix the vehicle with no idea that there were issues already about it.

Subject: RECALL VIOLATION: Kia on the Boulevard (Philadelphia) - Refused Remedy, Charged $199, Returned Unsafe Vehicle Vehicle Information: [Year] Kia Optima Hybrid Dealership Name: Kia on the Boulevard Dealership Address: 11295 Roosevelt Blvd, Philadelphia, PA 19154 Complaint Description: 1. The Safety Incident: While operating the vehicle, I experienced a catastrophic engine failure. Thick smoke poured from the engine compartment, followed by immediate stalling. This presented a severe fire risk and safety hazard. 2. Dealer Misconduct & Illegal Charges: I towed the vehicle to Kia on the Boulevard (11295 Roosevelt Blvd, Philadelphia) for the active engine recall remedy. The dealership: * Refused to perform the recall repair free of charge. * Forced me to pay a $199 "diagnostic fee" just to look at the recall-related defect, which should be covered by the manufacturer. * Threatened me with $45/day storage fees if I did not pay the $199 and remove the vehicle immediately. 3. Current Status: Under the threat of accumulating storage fees, I was coerced into paying the $199 and towing the vehicle back to my residence. The dealership knowingly released a vehicle with a catastrophic engine failure (smoke/fire risk) back to the owner without performing the federally mandated remedy. The unsafe vehicle is now sitting at my home unrepaired. 4. Conclusion: I request an immediate investigation into Kia on the Boulevard's refusal to honor the recall and their practice of charging customers for recall-related inspections.

The headlights and brake lights have been VERY dim for a while. I've had to replace both headlights and brake lights an excessive amount in the last several years. This year alone since December 2024, I've had to replace my headlights 3 separate times. I do not drive more than 10,000 miles per year, or use my vehicle on roads that would lead me to believe the issue is from road conditions.

I own a 2017 Kia Optima. My vehicle was brought in for the tail light recall at Lupient Kia, but the dealership only replaced a bulb and refused to replace the harnesses. I was told by the service advisor (Brad Baranowski) that my tail lights had “nothing to do with the recall” and that I would need to pay $210 for a diagnosis, even though I am still experiencing the exact defect described in the recall (shortage/failure in the harness causing tail light malfunction and warning lights). This incomplete recall repair is a safety hazard my tail lights continue to fail, and I have received tickets because of it. I request that NHTSA investigate Kia’s failure to properly complete this recall. Lupient Kia 6030 N Green Bay Ave Glendale, WI 53209 Phone: (414) 351-3000

Vehicles Low-Beam headlights are very poor. Brought for service/adjustments and was advised that they were properly aimed and that nothing more could be done other than installing brighter headlights. While driving at night I need the fog lights or the high-beam lights on for proper visibility which could cause issues for other drivers on the road.

When I turned the ignition on the car wouldn't start. But the ABS light and all other lights flickering when trying to start the car. The alarm kept going off. Passenger side front and rear windows won't function. Smell like something was burning. This is the second incident ([XXX]). Fuses had to be removed to silence the alarms on the first incident on [XXX] because the lights were still flickering on and off when car wasn't on. I had my car serviced at the West Broad Kia Dealership in Richmond, Va. Thank you! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Power train: at low idle or while slowing down, the car will lose power for a minute until you get on the accelerator and it all comes back on. Alternator had been replaced. And is going to be replaced again soon. Not sure if it's just a bad part. Power steering pump was replaced. The pulley seized. Unrelated. Lighting: third brake light constantly flickers. All Lighting including head lights flicker on and off. Worse when slowing down. Lights on dash board, dome, rear light and head light Bulbs have been replaced. At night when the head lights flicker I cannot see the road. Airbags: the air bag light on dash is always on. Codes have been ran and there are so many. Tried resetting codes it comes back on soon after. Not sure how to go about trying to fix it. All of this has been happening since I purchased the car in November 2024.

Low beam head lights visibility maybe reaches 3-4 feet infront of car at max. Have upgraded bulbs twice to higher lumens but still must run hibeams at night. I drive mountain passes daily and must use hi beams, not safe for oncoming traffic.
NHTSA complaint #11643250 — an unverified report by a vehicle owner.
The contact owns a 2014 Kia Optima. The contact stated while driving at night, the low-beam headlights were very dim. The contact stated that the high-beam headlights had to be used while driving in poorly lit areas. The contact had called a local dealer and was informed that a diagnostic test was needed to check the headlights. The contact had taken the vehicle to an independent mechanic and was informed that the reflective coating in the headlight assemblies had deteriorated to the point that there was an accumulation of reflective material debris on the headlamp floor and that other reflective material was peeling away from the sides of both headlight assemblies. The contact was advised by the mechanic that the heat of the light bulbs was degrading the reflective material. The headlight assemblies were not replaced. The contact changed the light bulbs and both headlights were still dim. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 135,000.

My 2012 Kia optima headlamps are extremely dim, even though I’ve replaced the lightbulbs with the highest possible lumens, multiple times, the headlamp assembly continues to dim. This requires that I ride with my high-beams on to drive at night. The lights have been dimming for more than 20,000 miles, but they are almost useless at this point.

Kia Optima headlights turn off randomly while on automatic. This dangerous issue has been investigated on other Kia models by the NTSB, which them prompted Kia to issue a recall. I have found many, many posts on car and Kia forums about headlights shutting off while driving at night with the Kia Optima (as well as other Kia items). It's very scary and very hazardous. This is a widespread issue.

After getting HECU recall done , it has caused issues with the HECU module to where the brake lights no longer work and the ESC light comes on the cluster panel. Up on reading the code C2130, it says Brake lamp relay error. Mind you that my car was in working order before this recall was even done. This a huge safety issue not having your brake lights work. I can get rear-ended and i have kids in the car. This has been a issue since July when i got the recall done and KIA has yet to find a fix for this matter.
