Headlights, set in AUTO, randomly will briefly go dark at night while the vehicle is in motion, putting driver at risk of night-time crash. Headlights can be re-illuminated by turning the lights off and back on. This issue has not been by dealer, service tech, or any other party.

Headlight malfunction shut off problem. At night when in motion on various city streets the front and rear lights will, suddenly and randomly, with no driver input whatsoever, shut off completely both in the back and in the front of the car! The headlamps and rear lamps will, at that point stay completely off with absolutely no exterior lighting function except the brake lights!!

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.

The headlights failed and yes it can be inspected . The headlights while my 16 year old daughter was driving at night. She could not see the road there were no streetlights. She had to hit her brakes turn the car off and restart and the lights came back on . This put her life in danger I cannot believe there are no recalls . We have called numerous mechanics to fix and they have not heard of the problem. I do not trust Kia to fix this . She could have died . Before this happened the dash showed the lights changing themselves from auto to on to off . This also happened to me while driving at night . We now do not drive this car at night out of fear .

Kia Optima Hybrids from 2014-2016 and most likely the two previous model years all have defective taillights. I know this because I've had two Optimas and I've had to replace 9 taillights in 4 years. The Kia dealer service department told me that that was quite typical of these cars.

Mid september, 2020, I began to notice that my headlights would turn off as I was driving. They would cut off for no more than 15 seconds and turn back on. I didn't think anything of it, until I started having issues with other components of my 2016 kia optima.

Headlights randomly turn off when set to "auto" position when signaling. Does not happen frequently but any time it happens is too many times for your headlights to randomly turn off. Happens while driving at night and happens when signaling to change lanes.

So I just took my wifes car to our local mechanic who normally does our oil changes. The prior weekend I moved her car to mow the lawn and her oil light came on then went right off. I let it go because we where due for an oil change and didnt think anything of it( considering it's a 2016 and thought maybe the oil light would come on stating it needs an oil change).

Whilst the vehicle is in motion on any road the headlights will shut themselves off for a few seconds and then turn back on. This happens when the switch setting is set to auto or is in the on position. When I google search the issue I see that there are many people with this issue.

While driving at night the headlights will go off by themselves while I have the switch in the auto mode. This has happened several times on both highway and back roads.

I was driving at night when both of my lower beam headlights went out at the exact same time. My high beams work but not the low beams and it wasn't a blown fuse. Also, my engine has been consuming 2 quarts of oil every 1,000 miles since it hit roughly 58,000 miles.

Headlights shine only on the road straight ahead.side lighting is so bad you can't read the road signs on the side of the road. This is the first time that I have driven the car at night on country roads. The headlights do not fan out on the road ahead at all.
