What owners say about the exterior lighting

Verbatim from NHTSA complaints, newest first
“Vehicle was purchased in 2023. AC blower failure occurred for the first time in June 2024 and was repaired by PepBoys. On 4/2/2025 the ve3hicle had an active recall event when the engine seized on the highway because of a faulty oil pump/filter, Engine was replaced 4/17/2025 under that recall. Kia advised at the time that the wiring harness should be replaced due to electrical issues at the time but said that there was no recall for that work. At the time, there were no electrical failures of steering, brakes, all power etc. Nor did we know that those were a possibility. The wiring harness quote was $7,000, over the cost of the vehicle. It was decided to continue repairing the electrical issues as they came up, it was assumed that the fuses would blow before there because a safety or total vehicle failure, as automobiles are designed that way. 8/4/2026 the vehicle experienced a complete and total loss of power resulting in a traffic crash into another vehicle as the brakes felt like you were trying to push a wall rather than a pedal. There was minimal physical damage to the other car and the kia, the other driver got my husband's insurance information and then…”

“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…”

“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.”

“My high beams and low beams are starting to shut off randomly. When it happens, my dash shows that i am trying to turn my headlights from auto to another setting, which is not the case. It has happened at night and that poses a danger because i cant see the road and people cant see my car. I have not had it looked at yet. I do see multiple complaints online for multiple different kia models and years. There is no recall and i do not see a TSB.”

“Headlights will randomly turn off when driving. I then have to quickly turn the headlight switch from auto to off to on to get them to come back on. There are numerous complaints online regarding this very same problem with Kia Optimas and other Kia vehicles. This is extremely dangerous.”
