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. I will like an investigation of this issue and if you can start a repair campaign recall due this soonroof parts are really pricey. And I think is a manufacturer problem.

Failure Date: 01/01/2023

I was driving my car and it just slowed down on the freeway and wouldn’t go pass 60mph I went to my nearest autozone and received code p1326 I was told it was the knock sensor and got it changed. I checked my oil and noticed it was low even tho I got an oil change not even a month before. However the problem didn’t change. I decided to go to the internet and notice many other kia have had these problems and have received a recall.

39 Electrical System problem

Failure Date: 10/27/2022

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. Over time, this defect becomes increasingly severe until you have a complete without warning failure like in my case. Kia motors refuses to acknowledge problems and stated there is no recall by NHTSA. I want a full reimbursement for my out of pocket payment for untimely repair cost.

40 Electrical System problem

Failure Date: 10/26/2022

On sept. 21, 2021, my kia Optima hybrid ex shut down and would not start. I took it to king of hybrid ev auto repair where they ran a diagnostic test and found that there was an issue with the hybrid system affecting the transmission and the high-voltage system. I paid $3,000. 00 out-of-pocket. On October 26, 2022, while driving 75mph on hwy 15 to las vegas, my car randomly shut down. The dash warning lights read "stop vehicle to charge battery". I was in an unsafe position with cars speeding past me. I was afraid that I would be rear-ended by another car. I had to have my car towed. I believe that these cars have issues with faulty high voltage systems and transmissions. Please investigate. Thank you.

41 Electrical System problem

Failure Date: 10/17/2022

2016 kia Optima was towed to kia dealer after it became inoperable; on 10/22/22 diagnostic done and found engine failure. Kia motors denied claim for repair/replacement. Not sure why not covered under class action settlement, and/or extended warranty, or subsequent technical bulletins regarding kia's defective engines.

42 Electrical System problem

Failure Date: 10/13/2022

Was driving my car and it just lost all power and cut off. It will not start now. It only has 1 click. The car has used a lot of oil since I've owed it. I do regular oil change and the oil lights still go off and on. I researched why it had power failure and replaced the starter but that didn't work. I started looking into the engines for 2016 kias n found out some have a recall. I hope my car falls in that recall bc I need it fixed . My car gave no warning signs that anything was wrong . Just cut off all of the sudden and will not start . Had to have it towed to my home.

43 Electrical System problem

Failure Date: 10/05/2022

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). All of the areas could put my life in some type of danger or a family member if kia doesn't see fit to remedy these areas. In 2018, my warranty was out and I didn't know until I received my bill the service person didn't advise me of this issue. So, I ended up paying $700 for a battery installment when I advised him that it was the issue, he insisted I get a diagnosis done.

44 Electrical System problem

Failure Date: 08/21/2022

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. The car windows are rarely let down. The passenger side rear was the first to fail. The driver's side rear failed 4 months later. The passenger side front was the third to fail 3 months later. It seems like this is a very common problem, but kia has not set up a recall. Instead, they are raising the price of the window regulators. Interestingly enough, the new regulators have a blue gear instead of a white gear.

45 Electrical System problem

Failure Date: 05/26/2022

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.

46 Electrical System problem

Failure Date: 05/22/2022

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. From video evidence, we can see that all it takes to steal a kia is a screwdriver and a usb cord. Kia’s stolen are driven recklessly and harmfully to pedestrians (see #kiaboyz on tik tok or instagram). Problem has not been acknowledged by kia or Hyundai. Insurance providers are aware of the situation.

47 Electrical System problem

Failure Date: 05/06/2022

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.

48 Electrical System problem

Failure Date: 03/28/2022

My steering wheel locked while I was on my way to work early Monday, March 28,2022. I was driving down county road park avenue around 30mph and suddenly, I was unable to move the steering at all. Luckily, I was already in the right lane =; however, it was very challenging to steer to get off the road. I called the local dealership and they suggested I bring the car in for inspection to determine what the cause is. I took the car to the dealership and I was informed the vehicle was not drivable because the steering wheel column assembly and ecu needs repair. They also informed there was no recall on the vehicle. The mileage at the time was 67,400 miles which was very surprising. I received a letter from Kia Motors in February 2022 (6 years after the car was manufactured about the recall however, most cars at this point were out of warranty and kia was aware no car met the warrantee qualifications). I was told by Kia Motors customer service that my vehicle was out of warranty at the mileage. I paid $3386 for repairs which should have been covered years in 2019 and 2020 according to other reports of the same incident occurring to other 2016 kia Optima models.

49 Electrical System problem

Failure Date: 03/16/2022

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. *today was the second time that I was surprised to find that there was not enough oil to even register on the dip stick. I don't yet know if there was any permanent damage to the engine. My experience seems to be very similar to many other people who have posted online. . . . A possible flicker of the oil light before finding out about the oil deficiency. It concerns me that others said that this led to their car faltering and/or freezing up while driving. That is certainly a safety risk for the drivers/passengers and other motorists. Some people indicated that their engine was ruined and needed to be replaced. Was the valvoline mechanic that told me today that there was an issue with these engines causing high oil consumption. *I have not yet had the engine inspected. I just emailed the kia dealership to inform them and ask about a possible repair. Last year was the first of two instances where I experienced the low oil level. The first time, I had noticed the oil warning light flicker when I rounded a corner a few times during a week or so. I then took it in for an oil change. Today, I noticed one flicker and went right to valvoline and there was almost not oil remaining. My second issue of concern is that my headlights have randomly turned off when I am driving at night. The first time I thought that I might have accidently touched the switch. However, it has happened two more times that I am aware of and I am sure that I did not touch the switch. I'm not sure if the headlights would have gone back on on their own because I turned the switch from on to off and back again and the lights went back on. There might have been more instances which I have not bee aware of. I just sent an email to kia about both of these issues. This is item has not been inspected.

50 Electrical System problem

Failure Date: 02/18/2022

The contact owns a 2016 kia Optima. The contact stated that on four occasions while the vehicle was parked and the window switches were depressed on all the windows, the windows failed to roll up or roll down as intended. The vehicle was taken to a dealer where it was diagnosed that the driver's side window regulator had become dismantled, allowing the glass to move up and down. The contact was informed that the window regulator and panel assembly needed to be replaced. The vehicle was repaired each time. The manufacturer was not notified of the failure. The failure mileage was approximately 21,000.

51 Electrical System problem

Failure Date: 12/14/2021

#1headlights & break lights going out often. Bulbs can’t be replaced anymore due to wiring burnt ( 1 headlight ) took it in and they didn’t even look at it. Have do documents to back that up #2 engine light coming on, diagnostic testing indicated spark plugs need to be replaced . Had to do this two times with oil on plugs took it in and they never look at the spark plugs #3 car burning excessive amount of oil anywhere from 1 quart a week to 3 1/2 quarts after driving 600 miles. Took it into the shop for oil consumption testing only to be told that their warranty would not cover it and it needs a new engine. I have a 10 year or 100,000 mile warranty on my car! and at the present time I only have 88496 miles on my car I have documentation to back up my claim, I have been a loyal kia owner for 18 years and they have absolutely treated me horrible in regards to this saying that it was lack of maintenance and they never checked the issues that led up to their findings. They indicated that there was sludge in my engine but could never prove or show me anything that they did to document the sludge and trying to blame it on me. This car is a safety hazard as I am aware of Mini other kia Optima’s dad have either caught fire or repaired to have their motors replaced due to the same issues. Anything you can do to help me with this issue ! I’m 60 years old and know how to take care of my car.

52 Electrical System problem

Failure Date: 11/10/2021

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. There is over 100 articles of people talking about this exact problem with 2016-2017 kia Optimas and I read apparently kia is even aware as they sent out an alert to dealerships about it or something along those lines? well that’s all great and dandy but what about the people who already have the car and are dealing with the problems? I have 2 kids under 2 and it’s a tough financial time. Even with the duct tape, it doesn’t always hold and the window will fall down on the highway and my son starts screaming crying cause its loud and the hard wind hits his face. This should be resolved. It shouldn’t take more than like 5 people complaining about the same thing for it to be deeply looked into and fixed. There’s well over 100 people talking about online like I said.

53 Electrical System problem

Failure Date: 09/23/2021

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. A couple of days ago my husband said he noticed that the oil in the car was running low really fast. We had just done an oil change on the car not even 30 days prior to this. We were driving late at night back from a work trip when al of a sudden the check engine light came on and the motor started to shake and a thudding noise was getting louder. We were able to pull over and saw that there was literally no oil in the car. No warning nothing. Again we had just had an oil change not even 30 days prior. My father had to come tow us home an hour and a half away because he was worried with the sounds it was making that it might blow. There was smoke coming from the exhaust and the motor was shaking like it had no control. I’ve read multiple issues just like this one and of course my car just passed warranty. I’m not even done paying the car off. This should be an issue kia has to fix by now with so many similar complaints. It’s dangerous and fraud. I’m just lucky the car was able to pull over safely as my husband and our 8 month old were in the car with me. Please help get this fixed. I’m now out of a car that’s only 5 years old and not paid off.

54 Electrical System problem

Failure Date: 09/21/2021

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. After that whenever I press on the gas pedal nothing happened there was zero propulsion. I took the car for inspection the hybrid battery was depleted so it got replaced but then the engine itself isn't working and apparently there is a metallic parts in the oil my car is available for inspection if needed it was definitely unsafe to break down in the middle of the highway I believe the normal non hybrid car had a recall issue with the engine and the hybrid has the exact gas engine the 2. 4l one the car wasn't inspected yet by the dealership as it is hard to get an appointment the car had 2 codes before breaking they were p0014 and p0420 they appeared approximately 2 weeks before the incident.

55 Electrical System problem

Failure Date: 09/09/2021

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. This is very dangerous for this to happen it is going to cause someone to lose their life if it hasn't happened already. This really needs to be looked into a recall for this issue. Please fix.

56 Electrical System problem

Failure Date: 09/01/2021

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. Wanted $800 to repair ( no longer under warranty). Took vehicle to my mechanic, who ordered the part and replaced sensor. Abs lights & bsd lights went off for almost 2 weeks, then came back on. Air bag light has not gone off.

57 Electrical System problem

Failure Date: 08/18/2021

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. I was able to get them back on. I started doing research and other people have had the same issue stating that it is the multifunction switch. Again this morning driving in the dark they turned off completely again. This is dangerous for not just the driver and passengers of the car but also other drivers if you can not be seen. This needs to be recalled and needs to be fixed sooner than later. Please help.

58 Electrical System problem

Failure Date: 08/07/2021

Since 08/07/21 I’ve been having intermittent issues with my oil light and engine light coming on. I have had all repairs recommended by the mark kia scottsdale, az dealership yet my oil consumption has increased significantly and the oil light continues to come on 02/14/24 I took my car to a local auto repair shop to get a second opinion due to the oil light coming off and on; they found the engine oil very low and only 1 quart came out when doing the oil change; they also recommended injection induction service which I’ve had done twice previously with the kia dealership.

59 Electrical System problem

Failure Date: 08/05/2021

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. I find it mind boggling that all four of my windows have to be repaired. It is completely unsafe that my windows just drop at any given moment, especially if it’s pouring raining or even at night when it’s locked my personal stuff isn’t safe inside.

60 Electrical System problem

Failure Date: 04/14/2021

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. This safety issue needs to be investigated . Very dangerous to drive without headlamps. Someone please make note of this serious situation immediately!!!!.

61 Electrical System problem

Failure Date: 03/29/2021

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. This has been an ongoing issue with this car, and it seems to be a common issue for other owners. I asked my local dealership about fixing the headlights, they told me it was going to cost $400 and they are aware of this being a defective issue with other owners. I am not going to pay for something that is a manufacturer defect. Please take a look at this issue, every efforts should be made to make this a national recall issue.

62 Electrical System problem

Failure Date: 12/03/2020

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! had to start using super to eliminate a rattle while accelerating uphill! engine shakes!!.

63 Electrical System problem

Failure Date: 10/06/2020

Sometimes when I start the car it only runs at about 500rpm and the digital speedometer starts going up in numbers when I'm in park and I have no power steering. I can put the car in drive and park or open the door and it starts acting normal. It also acts like it's going to shut off when I come to a stop. I am aware that the rpms drop when you stop almost like a gas saver but with in the last 20 thousand miles it has gotten really rough. It burns oil like crazy the dealership is aware of this but can't do anything with the engine tell it throws a code and they can't duplicate any of my other issues, the front end has made awful noises for the last 50 thousand miles or so and has had the front suspension replaced but that didn't fix the issue. Iv has the knock sensor replaced but I'm convinced it was just a gimmick so the car won't throw codes anymore because it should be with the issues I'm having. Like when the electronic steering goes out I get no dash light. I wish kia would own up to their issues.

64 Electrical System problem

Failure Date: 09/24/2020

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.

65 Electrical System problem

Failure Date: 09/10/2020

All 4 of my windows will not go up or down. This happened within weeks of each other. There is no cheap solution. Kia wants $150 deposit and I was quoted $225 per window. This is insane. I am driving a car where the windows are all wedged up which is a safety hazard. I am not the only one with this problem. Are there any recalls for this?.

66 Electrical System problem

Failure Date: 09/07/2020

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. In addition to that the car doesn't respond to the key fob most of the time even with brand new battery in the fob. Step dad has the same car with same issues with the key fob.

67 Electrical System problem

Failure Date: 07/15/2020

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. About a week or so later while driving on a local street in my town my driver side back passenger window slid down I began hearing and feeling wind come through the window I called my dad who lives in miami he told me to put a flat head screwdriver down in the window to keep the window from sliding down and possible breaking and to call the dealership. I called the kia dealership I was told to make an appointment to have the windows looked at. (which I did) a couple days later while picking my daughter up from work I was backed into a parking spot. I rolled the back passenger side window down to let her know I was there since she was more to the back side of the car then the front and all behold the window would not go back up. I called kia 1st thing the next morning and was told my car had a recall for the electrical but they could not do anything about my windows unless I paid out of pocket because the recall did not cover the windows. I'm upset because I do not have money to fix 3 windows had I not had that electrical problem my windows would still be working.

68 Electrical System problem

Failure Date: 07/09/2020

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

Failure Date: 03/11/2020

3rd window motor that has failed in just a few months! first my back two window motors and housings needed to be replaced and now my front driver side window is down and will not roll up. On the way to work this morning it stopped working and now my car is sitting outside at work unsecured. Kia contacted me regarding my last complaint and is working to see if I can be reimbursed for the second window. I am waiting for a response now to my email and call this morning regarding this third window.

70 Electrical System problem

Failure Date: 02/01/2020
