  1. Electrical system, Visibility, Engine, Jun 3, 2024

    The contact owns a 2016 Kia Optima. The contact stated while starting the vehicle, there was a loud knocking sound coming from the engine, with the check engine, oil, and battery warning lights illuminated. Additionally, the contact noticed that all four windows failed to function properly and failed to roll up. The dealer was contacted; however, the cause of the failure was not yet determined. The vehicle was not repaired. The manufacture was made aware of the failure. The failure mileage was approximately 124,000.

  2. Electrical system, May 4, 2024

    our ac keeps blowing relays. every month. and they other day we have to force power bank to the blower motor just to get it to work. half the inside and sometimes the even the outside lights works.

  3. Power train, Electrical system, Engine, Apr 20, 2024

    The Hybrid Battery continues to malfunction and, randomly shuts down at any speed (even after short engine block was "repaired" by Kia Dealership). Also, an odor of burnt oil happens often while driving the car. It is available for inspection, if need be. Safety of all drivers at risk because car shuts down on freeways and highways. It's dangerous where cars driving at speeds of 65 mph are unable to break and avoid collision. Kia calls their RECALLS "CAMPAIGNS". The Kia dealer has acknowledged this problem and has performed maintenance, however the problem still persists. I have the recent receipt of service/ maintenance on my 2016 Kia Optima Hybrid on hand. The first time it happened was on September 25, 2021. There were no warning lights or messages, the car simply shut down and had no power and was not drivable. I took it to a hybrid mechanic who ran a diagnostic test. The hybrid mechanic repaired my car. 6 months later, while I was driving my car seized on me while I was driving on the freeway going 65 miles an hour. This time a warning on my dashboard showed that there was a problem with the hybrid control system on the car. We took it to a Kia dealership and they performed a diagnostic test and said that I needed a new short engine block and hybrid battery replacement. (I have the receipts for the maintenance performed by Kia Dealership) It took 3 months for The Kia dealership to rebuild the engine block and replace the Hybrid battery. On March 7, 2024, my 2016 Kia optimal hybrid seized on me while I was driving 40 miles an hour. The message/ warning now says "Battery Management System Failure" "Possible BMS Condition." "Check Hybrid System". Kia does not acknowledge that there is a problem with the hybrid system in the Kia Optima hybrids. I've called and tried to file a complaint, however they tell me there are no problems with the Kia Optima hybrids. Please investigate. Thank you for your time and attention to this important matter.

    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: 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

  9. Electrical system, Visibility, Feb 8, 2024

    The contact owns a 2016 Kia Optima. The contact stated that while driving at an undisclosed speed, she became aware that the driver's side window was not functioning. After which, all the windows in the vehicle failed to operate as needed. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with all four window regulators. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 70,000.

  10. Electrical system, Engine, Fuel/propulsion system, Jan 8, 2024

    My Kia Optima randomly stops working while driving. I get a notice that says, "HEV: Check Hybrid System. Stop Vehicle and Turn Off Engine." Also the gas pedal stops working, leaving me to try to coast to safety. The car essentially stops working in the middle of driving, without warning. Once this happened and blew out the spark plug, requiring a new one. Then, a day or two later, the car returns to normal. The Kia dealership could not reproduce the problem, nor could my service center. They say it's fine. I took my car in for previous recalls, and it is currently "up to date." This appears to be the same electrical issue as a recent recall for electrical failure, but the dealership told me the spark plug was fine and that I should change the battery. I did and this still happened. I do not feel safe driving this car, and Kia won't help me find the problem.

  11. Electrical system, Wheels, Engine, Nov 20, 2023

    We have had two motor replacements in less than 6 months that we have owned this vehicle for the first one started started a knocking noise right after a flashing check engine light both Kia is by us totus will we can't get it in today wouldn't give us a rental and was going to charge us for a diagnostics fee right up front and told us it would still be a few days before they could get it in so we had no choice but to continue driving it not even 2 days later left my fiance on the side of the road wouldn't start wouldn't do nothing engine seized Kia dealer number one put the motor put it back together wrong and then when it seized again in less than 5,000 mi try telling us that they weren't responsible well if we did the engine again give it back to us notice that the ignition coils were not put on properly and orbital down properly You're still an electrical issue and the engines are starting to do the engine is starting to do the same as engine one and two. What I don't understand is why don't Kia just completely recall the entire car and take it off to fucking market and replace the people replace the cars that have that still have people owning them

  12. Electrical system, Structure, Engine, Oct 23, 2023, fire

    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.

    The engine was has blown twice the first day 95000 miles and again at under 6000 miles. And there is still a bad knock and major vibration and ticking noise coming from the car. We told the car we no longer have faith in this car and didn't want it no more and all he did was see if he could get us another loan to trade it in. We're now scared to really ride in to and can't get no one to help us on this my man is about to lose his job over this car

  15. Electrical system, Sep 6, 2023

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

  16. Electrical system, Exterior lighting, Aug 23, 2023

    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.

  17. Steering, Electrical system, Jul 24, 2023, crash

    I was driving and the car’s electrical completely cut out and locked my steering wheel up and ran us off the road and we hit a big rock on the driver side and then the power kicked back on and the steering yanked super hard to the right about 4 times and caught a fallen tree on the right side then completely died with me and my young kids . Took it to Kia to be serviced and got it back and it started to do it again

  18. Electrical system, Engine, Fuel/propulsion system, Jul 8, 2023, fire

    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.

  19. Electrical system, Engine, Jul 2, 2023

    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.

  20. Power train, Electrical system, Engine, Jun 4, 2023

    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.

  21. Steering, Electrical system, Jun 4, 2023

    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.

  22. Other or unspecified, Electrical system, May 15, 2023, crash

    We received a recall notice for our KIA Optima to get the software upgrade to restrict operation of the vehicle without a key. We took the car to the dealership on 5/5/2023 for the recall and picked it up on 5/5/2023 from the dealership at 3:30pm. On 5/8/2023 our car was stolen out of our driveway. It was recovered on 5/12/2023 by our local police dept. and it was stolen by using a USB cord and starting it without the key. Obviously the recall does not work. There is now damage inside and out of my car. I did notify KIA corporation last week that it had been stolen and have not heard from them. I also sent an email this morning letting them know that the car was returned and confirmed that they stole it they way the recall was suppose to fix so that it could only be started with the key in the ignition. Obviously that did not work.

  23. Electrical system, Structure, Apr 25, 2023

    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.

  24. Electrical system, Visibility, Mar 11, 2023

    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.

  25. Electrical system, Other or unspecified, Engine, Mar 10, 2023

    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.
