2016 Kia Optima Electrical Problems

The engine almost caught on fire. Windows are all down .

Engine failure; oil consumption, misfire, smoking, losing sped, no acceleration. Problem has been diagnosed by 3 mechanics in a mechanic shop. Only warning was the check engine light

Heavy oil consumption , unintended acceleration , car jerks . Back window occasionally won’t roll down .

The body shop later informed me that there is a recall for engine fire recently,but my year/make is not listedin the info obtained online. The car started stalling while driving down the off. Smoke started coming through the vents. I pulled over to the side of the highway. A passerby told me that the car was on fire. Called 911. To note I had just picked the car up from Jim marsh Kia for battery replacement and problems with steering after the car was stolen in July. I had no previous issues with my car other than routine maintenance which I have records for.

On July 4th, my vehicle lost engine power and flashed a quick prompt of "engine warning" before turning off completely, smoke from under the hood which resulted in a fire. I was able to extinguish it fortunately. I have since discovered there are three open recalls, which I received no notification about. I frequently check for recalls and all sites say there are none.

*The vehicle is burning oil at a very speedy rate....much quicker than normal. Perhaps more than a quart per 1000 miles. The car is available for inspection.

I was driving at night lights turned on of course then all of sudden they turned off I couldn't see I had to slam my brakes on almost crashed and this is the 3 time this has happened I usually don't drive at night so I didn't notice this problem as a problem I was thinking maybe it was the street lights were to bright and caused them to turn off but on a very dark street with no lights and it happened again then I realized this is a serious problem but this has happened the times I have drove at night.

My 2016 kia optima bursted into flames while stationary in front of my home.

As I began crossing the intersection (highway) I ended up getting t- boned halfway through the intersection by a pickup. He was speeding going roughly 60mph in a 45mph zone my kia optima sustained passenger side/ and frontal impact damage. The impact of the accident sent me skidding across the highway and none of my frontal airbags activated nor did the seatbelt lock up.

My vehicle has been having engine & electrical issues, I originally took the vehicle to a secondary mechanic after Kia Baltimore stated it would be a couple months before they could diagnose the issue. The secondary mechanic was changed spark plugs, and other fixes but advised the vehicle engine was still shutting down and he believe it was related to the Kia engine recall issues.

I have a 2016 Kia Optima within the 2nd year all my window motors fail within a 6 month timeframe. My car in the 4th year started to burn oil quickly the oil light would not appear until I begin to hear a knocking sound. Also, in the 4th year of having my car there has been cracking in my passenger side (I think it is where the airbag is located).

My car stalled while waiting at a stoplight. When going to accelerate I was unable to. However, I looked at the current recalls for my car.

The drivers side running light went out one day and my car alerted that it was out. I changed the bulb and that did not fix the problem. The fuse appeared ok, however I replaced it just to be sure.

Every window regulator is broken, 2 of them in the middle of the highway and the other 2 when I parked the car.

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.

This will be the second time this has happened to my vehicle my vehicle just randomly stopped while driving and will not start back up. It keeps showing on the dashboard “check hybrid system stop car and turn off engine” this happen 4 years ago and then a safety recall came out for it to get fixed this should have been fixed from the safety recall and never happened again unfortunately it happened again. The dealership is booked with appointments so my car will not get fixed for about a month or two. It is very dangerous for the car to just caught off in the middle of the road.

Soonroof/Moonroof closed rattle noise. When the Soonroff/Moonroof is closed at highway speeds or windy weather it make a rattle noise to inside of the car, I try to do their reset method and nothing worked, I being looking in kia forums and most of the people had complained about this issue, and that kia doesnt wants to fix.

Complete power window failure (driver and 2 rear windows). Estimated repair cost is $2,084.90. This model has a history of power window defects that Kia Motors is well aware of.

All four of my window regulators/and or motors have died within months of each other. First it was my back two, now my front two have gone and don’t stay up. I don’t have children nor frequent passengers.

First my driver side back window wouldn’t roll up or down. It just sags and falls down everytime I drive so I duck taped it until I could afford to get it fixed. Now a month later, the passenger back seat is doing this exact same thing.

Air bag light came on after I also began having issues with blind spot detection warning lights. ABS lights on as well. Took vehicle to Kia Dealer in Gainesville GA and they told me it was the left rear wheel sensor.

I was driving the car on the high way when I suddenly heard a strange noise from the engine with a shake in the car then the car completely switched to the hybrid engine from the gas one. The hybrid battery was depleted within a minute or two but I was able to put the car on the side of the high was before it completely stopped moving.

Since purchasing this car I’ve had to have electrical repairs done every year. If it’s not the seat it’s the window. If it’s not the window it’s the dash.

About 3 weeks ago my headlight Auto dash notification would flash on and off for probably 8 times. It was day time so I didn't think anything of it. Last week I was driving in the dark and my head lights turned off completely.

2016 kia optima has an issue with the vehicle headlights. They are turning off by themselves while driving. Today was a close one for me, it was 9:10pm and I was going about 50mph and all the sudden my lights went out and I had to break rapidly, I couldn't see anything in front of me.

Three of the window regulators failed at the same time and the forth two weeks later. I had them repaired for a almost $ 2000 since the the vehicle has 62k miles and the warranty was good till 60k miles.

My oil pressure light continues to turn on and off even after replaced parts! Burning at least 2 quarts of oil per week! Brake lights stop working if headlights are on!

In june 2020 after ordering food at a fast food drive through my driver side window would roll back up. I didn't think much thought maybe the window was off track.

I've been having car problems with my car for a over a year, the steering wheel get stuck, my brakes wasn't working good, so I got new breaks, however my car still doesn't make a quick complete stop, I'm also having electrical problems, my headlights bulb have to be changed once a week, I also have to changed my oil every well, today my car is at the dealership waiting on a engine, it's been there for over three months.

In august 2018 I noticed that the camera on the front grille of my 2016 kia optima was producing a blurry image. It did not do this the night prior when I used the camera to park in my garage (where I did not hit or bump anything, I was not even near the wall at the front of the garage). The lens had a crack.

I'm driving the car shuts off but comes right back on and sometimes the radio just shuts off and comes back on plus all the lights inside goes off.

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.

3 of windows do not roll up.

The front and rear windows come down unexpectedly. The power controls do not control the windows. This is especially dangerous when younger children are riding in the car and can reach their hands out the windows because the windows just come down.

At 95000 car had problem accelerating and then all of a sudden on the side of the road did that 2 had 2 engine rebuilds done no but the problem is still there and the fuses all look burnt and half my lights don't work.

Three power window regulators have failed over the course of a year. Without warning the window suddenly drops down and cannot be let up. On each occasion, the regulator gears appear to have just desecrated.

While driving down major highway the engine failed and the electrical system started blinking and I lost all power. No warning, dashboard just lit all up and engine seized up.

Every window in my car has come off track within a 3months time period . The motor steady runs in the door and the window will not move up or down.

Car was stolen off of the street. No alarm went off, keys were with my person. Back window was busted on the ground and all that was left.

My headlights have gone out 3 times in the last four months. I've never encountered this type of problem with any other vehicle. This car is s 2016 kia optima and had left me without headlights .I notice others have complained about the same exact problem.

All 4 of my windows will not go up or down. This happened within weeks of each other. There is no cheap solution.

It began when we would try to start the car it seemed to have battery issues and have trouble starting, and finally the battery did drain but isn't holding charge but took it in to get checked and battery is fine. The headlights will randomly shut off while driving at night like if the sensor were in the day time.

The cluster started blinking out while driving then eventually goes out completely. At the start of the problem it would go out at times then pop back on for about two weeks.

The headlights will randomly turn themselves on and off in day and night time. This only happens in the 'auto' option for the headlights. I have seen numerous other reports on this on here.

Fourth window regulator to stop working in the past year. The window rolled down and would not roll up.

The wiring in this vehicle is soy-based and is attractive to rodents. I have experienced rodent damage twice now totaling about $3000 in damages. I have contacted kia and they suggested making a claim on insurance.

Three out of four windows have stopped working. It started with the rear passenger window about 6 months ago, then the rear driver 3 months ago, and now the front passenger about a month ago. Did some research to find it's a pretty common problem on kia's for the regulators to break.

My rear driver's side window started falling down all of a sudden. I had to replace the regulator and the motor. Now, just a few months later, the passenger rear window is doing the same thing.

I am having an issue with the second window motor on this vehicle. From reading reviews, it's a common problem.

My optima seems to hesitate or studder when accelerating from a stop. It reminds me of a gear slipping but my car only has 11,145 mi on it so there's no way that's possible. This has been an ongoing observation for months now.
