The contact owns a 2016 Kia Optima. The contact stated that while driving at an undisclosed speed, the daytime running headlight would inadvertently blink on and off and turn off. The contact was unable to drive the vehicle at night due to the failure. Also, the rear driver’s and passenger’s side windows were inoperable. The vehicle was taken to the dealer, but the dealer could not replicate the headlight failure. The dealer replaced both rear windows. However, the failure recurred with the front driver’s and passenger’s side windows. The vehicle was not repaired. The manufacturer was made aware of the failure and informed the contact to take the vehicle to the dealer but provided no assistance. The failure mileage was approximately 90,000.

There have been 2 occasions while driving at night with the headlights on auto that the lights have gone off for no apparent reason. The vehicle is available for inspection upon request. I was driving on a major highway and was not able to get to the side of the road. The entire dash went out. This was very dangerous as I could not see anything in front of me. After jiggling the turn signal switch the lights did come back on. I have taken the car into a dealership and also into an independent service center to have the problem addressed. Neither location was able to reproduce the incident. The best guess from the dealer was a headlight switch and from the independent service center their guess was possible an ignition switch. Both of the estimates were unable to confirm that replacing the switch would correct the problem. There were no warning lamps, messages or other symptoms prior to the failure.

The contact owns 2016 Kia Optima. The contact stated that after an oil change on the vehicle, the mechanic informed the contact that there was only a ½ quart of oil in the engine prior to the oil change. A few weeks after the oil change was performed, the check engine warning light illuminated. The contact pulled the vehicle over to the side of the road and checked and noticed that the oil level was very low. The contact added 4 quarts of oil to the engine to fix the failure however, the failure recurred. The contact was concerned about the excessive oil consumption. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 100,000.

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

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

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.

2016 Optima with 111K miles: 7/17/19 car received ECU upgrade for the KSDS system. After upgrade, on 5/23/2020 at 90K miles, the car started to shake/knock, engine light came on, car went in to limp mode, car was taken back to the Kia dealer, code was recorded as P1326, another update was performed, and due to excessive damage bearings were replaced. Car performed ok until 9/22/21, again the car started to shake violently (bucking), loud knocking sound, engine light came on, went into limp mode, was pulled over immediately, dealership contacted, car driven directly there (3 miles). Notified at 4:30pm "there was a complete failure of the 'Fuel Injector System' and needed replacement". Was told that the "entire fuel injector system failed allowing fuel to soak and flood into the cylinder and spark plugs". This was ALARMING. Luckily, we knew to pull the car over and keep the RPMs below 1500, and only traveled a few miles. Had we been driving for a while, or the engine had been hot I do not think a rupture of the entire fuel injection system that again is located in the cylinders of the engine would have ended well. Kia Service now telling me the "Lifetime Warranty" on engine is not applicable bc a code did not get captured. The fact that my car previously captured that code speaks to the fact that the engine was faulty on production, misaligned, allowing damage to occur from mile 1 on. ECU upgrades and replaced bearings do not remove the damage that was previously sustained by the migration of metal shavings throughout the engine compartment for the 90,000 miles before it was detected and repairs were made. While the "Lifetime Warranty" speaks to engine replacement and engine repairs the original class action suit was due to engine fires, which you all (NHTSA) determined in its reporting that the exact cause of the fires in all cases was “undetermined”; noting dealers should be looking at fuel and or oil leaks within the engine. This is alarming to say the least.

Without heavy use (I don’t often have passengers in the back seat), driver side rear window regulator/motor failed in May, causing the rear window to fall into the door while driving. This is a major safety issue as anything can go through the car - rain or debris. It was roughly $600. This weekend, the same thing happened to another window out of the blue while having my dog in the back who nearly jumped out after it fell into the door. Now, the part is backordered and the Kia dealership has said it could be months before the window can be repaired and they offer no solution on how to keep the window up in the meantime. This is an expensive safety issue and should not be failing in multiple windows. My car only has 65k miles on it.

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. The issue occurred twice 9/15/2021, and once previously on an unknown date. There were no warning signs, dashboard lights, or any other indication of malfunction.

Here in Wisconsin Kias are being stolen at an alarming rate. It’s the most stolen car. It is being stated that this is due to how the cars were made and that Kia knew this but didn’t disclose it. My car was stolen at work, along with other coworkers. This is beyond insane. How many more cars have to be taken due to manufactures negligence for something to be done.
Air bags, Sep 14, 2021
A straight line crack about 4 inches long appeared suddenly on my dash. Upon doing some online research, I found that the crack is directly over the dash mounted airbag. I took the vehicle to the local KIA dealer and they said it was not covered by the warranty. My concern is that the crack may impede the deployment of the airbag in a critical situation. I feel it should be investigated because there are a lot of exact same complains on the internet concerning a crack at the same location.

I'm about to replace my THIRD window accuator on this car. The first one that failed was the rear passenger side at 54000 miles. The window was rarely if ever used, failed any way. The second failed at 60,000 miles.. driver side rear. Like the first, rarely used window. Now the third has failed at 66,000 miles. Cost to replace, over $300 because a $5 sprocket fails. Windows failing is definitely a safety issue.

While driving at night with the "auto" function for the headlights on they turn off at random. This has happened numerous times during the past year. Very dangerous on dark roads. Dealer could not replicate situation to repair. No warning lights appeared.

Headlights turn off and on randomly when headlight switch is in auto mode. Dangerous in the dark when suddenly the light disappears.

My dash told me I have a headlight out. The headlight seems to come on and off from time to time. Now it says both are out. Every now and again they both come back on. It seems as though I have an electrical issue going on all of a sudden. But could be due to the engine running poorly causing disconnections In the wiring harness. The engine is shaking pretty bad and awaiting my scheduled appointment.

The engine is sputtering. Dealership can’t get my car in for two weeks due to their full schedule. They stated as long as the check engine light isn’t flashing it’s ok to drive. The motor sounds like a farm tractor.

As I was driving on the highway my vehicle started to decelerate without warning. I was able to move to shoulder and when the car came to a stop the temperature gauge immediately went from cold to hot and the engine light came on and the dash displayed engine overheating. While researching what to do if your engine overheats, I came across the issues Kia has been having with their engines. I had the car towed to the dealership for inspection and was told my vehicle would not be covered because I didn’t do the product replacement which I had no knowledge of. After calling the manufacturer and talking to several reps I was ultimately blamed for the defect and not knowing about the problem so therefore it’s not Kia’s responsibility to fix my vehicle. One rep told me that Kia sent out notices according to DMV records, which means I should have received a notice. Another rep discovered that they did not have a correct address for me on file and said that it was my fault because I am supposed to update my address when I purchased the vehicle. I was also told by a supervisor that customers that buy new cars get priority in being contacted and that used car costumers are supposed to notify the manufacture when they buy a car so that’s why I received no notification of the recalls or product replacement. I received less than adequate customer service, and being blamed for a problem that resulted for Kias negligence is totally unacceptable.

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.

All four of my car windows fall down unexpectedly due a defect in the window regulator part, and window motor. The windows do not respond to door controls and I've now had to spend approx. $3500. and many trips to the dealer repair shop to get these windows fixed. I live in Florida, and when a window opens unexpectedly in the middle of a severe rain storm and cannot be closed, this is a safety hazard. I've had to pull over when there is very limited visibility on the road, and try, usually unsuccessfully, to close the window. The glass windows are fairly heavy and my attempts to tape them shut do not work. I've contacted KIA consumer affairs and have filed a complaint with the Better Business Bureau, but so far KIA has done nothing and has not responded to the BBB (according to the last BBB email I received). The 4th window is being fixed today at the dealer, and another window is getting re-repaired, I don't know if any of the repairs will last, as every few months another window breaks.

When I was driving at 4:45am it was total darkness still out my exterior headlights shut off and I could not see. It is always set on auto. It just happened out of no where and I could not see. I could have had an accident. Now i have read that a few people have had this same problem. About a month ago they kind of went off then on again bit i thought maybe they were switching to daytime lights. Now today they just shut off in total darkness. This needs to be looked into! Especially if many people report same problem. Now i did pull over where I could then switched the lights to just the on mode and they worked fine tell I got home but I don't know what's happening. Does this mean they will work on the on mode or lights eventually wont work at all?? Is it a fuse or relay? Idk please check onto this.

The contact owns a 2016 Kia Optima. The contact stated while driving 40 mph, the vehicle would not accelerate when the accelerator pedal was depressed. The vehicle was towed to the dealer and diagnosed as engine failure. The dealer informed the contact that the manufacturer had not approved the vehicle for an engine repair because the software update had not been performed on the vehicle. The contact stated that she had not received a notice from the manufacturer for the software update. The vehicle was not repaired and remained at the dealer. The manufacturer was made aware of the failure and initially informed the contact that the engine would be repaired under the warranty coverage however, the manufacturer later informed the contact that because the software update was not performed, the warranty coverage would be declined. The failure mileage was approximately 111,000.
