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.

Lost power while driving. Likely seized engine.

While driving home on the interstate the vehicle had a sudden loss of power. No warning lights or check engine lights were on prior to this incident. The vehicle would not start and I had it towed to a dealership who told me that the engine was low on oil and that KIA would not be covering the engine replacement. I provided the dealership/KIA with all of my service records showing that I had performed all maintenance to my vehicle at KIA dealerships and that I had never skipped any recommended repairs. I also pointed out that there was never any notes made that I should be monitoring for excessive engine oil consumption or that I had a leak anywhere to be found. Despite having all of my records in order, all of my services performed at a KIA dealership and in a timely manner, no low oil lights that came on to notify me that it was dangerously low on oil, and the known issues and recalls to these engines for this exact issue; KIA stood firm that this was not their problem and they would be doing nothing to assist me in the matter. This sudden loss of power on the interstate fortunately did not, but easily could have caused a fatal accident for me and those around me at the time and also could have caused a fire to start in the vehicle which could have been fatal as well.

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

- North Chesterfield , VA, USA

My engine has been consuming oil since 30,000 miles. It consumes in excess of 1 qt per 500 miles. There's zero dripping oil from under my car, it's all being consumed. I've lost power and gone into limp mode because it's consumed too much oil and ran dry in between regular oil changes. Kia has not helped me. I've done more than 5 consumption tests with a Kia dealer. And now Kia says that it's a warranty event. However they will not accept my warranty event without evidence of every self oil change such as receipts for oil filters or oil. I don't have all of these records so Kia refuses to repair my vehicle.

Heavy oil consumption, unintended acceleration, car jerks. Back window occasionally won-??t roll down.

- Fontana, CA, USA

I'm noticing that I'm burning oil frequently. I started to notice this becoming an issue summer of 2023. Once when I get an oil change about 3-4 Weeks later my oil light comes on. Then I would have to put oil and my car. The dealership always ask me if I'm sure that I want an oil change because I haven't hit my time for an oil change. 26th Feb 2024 I spoke with Kia Customer Care and they stated that this is not an issue and that oil consumption is not under warranty. I stated that I didn't inquire about the oil consumption. I repeated my question asking if it's a known issue that the Kia optimas burn oil. Angel the customer care representative stated that it isnt. However, I started how is when I took my car to numerous dealerships and mechanics that they all said the same thing. That I spoke to a Kia dealership before I called and they stated that it was a known issue. Once when I said that, Angel changed her story and said yes that it is a known issue but all cars burn oil. I asked was there a solution for this issue. Angel then repeated the same thing and I said thank you for your time and got off the phone. Needless to say there was no solution made.

When I was coming home from work my car lost power and didn-??t accelerate anymore when I was on the freeway. I almost didn-??t make it to the shoulder when trying to pull over. Every single light I could imagine came on when I was trying to pull over, It said check hybrid system, BSP system failed, etc. All the lights came on at once. My car didn-??t start, so I had to wait on the side of the freeway at 4am for a ride and a tow. Kia told me that I need service records to prove that I was up on my maintenance and that the reason my engine failed was at no fault of my own, But I am up on maintenance. That same dealership had my car in February 2023 and said my car was in perfect condition and up on maintenance, I just needed a new transmission. Now just a year later, Suddenly my engine failed and they are saying it might be because I didn-??t get oil changes. There are recalls on Kia engines made in 2016 but for some reason my car isn-??t included in the recall even though I know I took car of my car and that engine just wasn-??t good.

Oil light continues to come on only after 1 month of a 5 quart oil change. Only driving about 300 miles a month. Have taken it to a kia dealership where they said there was no oil leak. Took it to a private mechanic for a second opinion where I monitored my miles after an oil change and they found that it is an engine problem and the engine is burning my oil. This has been happening for the past 6 months. I did not have the mechanic fix the issue as it should be covered through the manufacturers warranty.
