Vehicle uses about 4 quarts of oil every 1000 miles. I have to get oil changes every 1500 miles and add oil every 1000 miles. The car is not reliable and oil light comes on every 1000-1500 miles after oil change. Today the emissions light came on and I could not drive over 60 mph, after taking it to mechanic it was over 3.5 quarts low of oil but no oil light came on. The mechanic put 3.5 quarts of oil in and I had to pay for oil and labor, also to put the car on the computer to see the issue. I will never buy a Kia again. There should be a recall on this 2016 Kia Optima.

I was on [XXX] and had already traveled over 300 miles with no previous issues at all on the trip. I had just stopped at a gas station and there were no odd smells or sounds. There also no warning light on the dash. Suddenly, I lost all power and at the same time my engine light and oil light came on. Before I could make it from the inside lane across two lanes of 70-80 mph traffic at a rapidly declining speed, my motor started knocking. My engine is seized up because of lack of oil when I just had an oil change less than 1,000 miles ago. I'm lucky [XXX] traffic didn't run me over before I could get out of the way. How is this same issue not a recall yet when people are at risk. Had someone not been paying attention to people In front of them my lack of ability to drive my car could have caused a horrible accident!

I was told that my engine had a recall on it so I had an upcoming appointment with Kia in like 2 weeks for them to check my engine but the car didn’t make it. I was driving my car on interstate 20 my car had began to have a bad chemical smell and started smoking so I pulled over on the interstate and my car was in flames. Me and my daughter was in the car we could have lost our lives thank God we were able to make it out just in time. The fire department came and made a report on the incident. It wasn’t any engine light on at the time. I have contacted Kia about the tragedy that has happened but nothing has been resolved yet.

Was on highway, engine seized, flashing engine light and knlocking noise, car went into limp mode, took to dealership code p1326 was thrown which is engine failure, I have had the knock sensor installed thru kia prior which put me in lifetime warranty for the engine, kia dealership did a diagnostic BCT, which is a 4 to 5 hour job at the most, kia called me in less than 2 hours and told me is passed the BCT ! there is no way they did the testing in less than 2 hours, and no way it passed with engine light blinking and knocking, that's what the sensor detects is engine failure, they are refusing to honor my warranty for the new engine , picked up my car from. Dealership, soon as I hit the end of the parking lot engine seized and loud knocking noise, was barely drivable but yet the lied on the paperwork and said it drives as designed and was fine, put in a new knock sensor which they already did a month ago! went right back in to dealership and they told me because it supposedly passed there was nothing they could do! R u kidding me!? They were rude and not wanting to help or honor my engine replacement, so here I am with a seized engine and they tell me nothing they can do till it fails the BCT! THE DAM CAR IS IN ENGINE FAILURE! In the last 3 months I have put 3k in this car! What is it gonna take for them to honor the new engine? Gonna take me, my kids, or someone else getting hurt before they do what they said they would do? I have been in contact with corporate as well and they have yet to get a return phone call from the dealership, they have left several messages and called bullshit as well, and believed I was treated poorly because I'm a female.....Little do they know, my father was a mechanic, he has passed on but I grew up around cars and know what's safe and what's not and know how long it takes to do a BCU test! Basically kia told me to drive it till the engine blows completely! I just want them to honor the warranty of the engine .

Vehicle first went into “limp mode” and dealer said high voltage recall needed to be done. Worked ok for a while then again “limp mode” dealer said knock sensor recall was happening and knock sensor was replaced. Few weeks ago limp mode again, all during car was moving in traffic. Car currently sitting at a Kia dealer, knock sensor again, haven’t heard from Kia regarding engine replacement

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.
Engine, Mar 25, 2024
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

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 .

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.

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
