I have been having some issues with my Kia Optima. It is consuming so much oil. Constantly have to get oil changes. Recently, my engine light went on. Was told it was because of all the oil that is burning. Car does not perform properly. It does not want to accelerate. It feels like it will turn off. I get scared driving. What if my car stalls in the middle of the busy LA traffic? I have gone do dealership so many times. Whenever, I say the reason why I need an appointment, they tell me they have no available time slots. They just told me they will see me next year!! I say its because Kia doesn't want to fix it. Several mechanics have informed me that my engine needs to get replaced because of the excessive oil consumption. Kia needs to pay for it. They know it-??s their fault.

Driving along the interstate approximately 70 mph, the vehicle jerked with knock sound then lost acceleration speed. At the same time, the check engine light started blinking. I pulled over to the side of the interstate put the car in park. I put it back in drive and slowly attempted to accelerate again. I was able to make it home because I was only about a mile and a half away, but I the acceleration was very slow and there wasn't much power behind it. At a speed of about 45-50, the vehicle barely seemed to have much power.

I took my car in for an oil change and it was extremely low on oil, I found out that Kia has a class action law suit for excessive oil consumption. I had the test performed at a Kia dealership and it does in fact have the oil consumption issue, it was down 2 quarts within 1000 miles. Kia is saying that they will not cover it or perform the necessary fix that is required (replace the engine or at least perform the combustion cleaning procedure). This in my mind is a safety hazard and Kia should back their product of a known issue. My wife drives this car and if the engine locks up she could be stranded or injured if it happens on the road.

The oil is leaking into the engine, was taken to a kia dealer for repair $542.45 unsuccessful, I am putting oil in my car every 3 weeks. Purchased the car in April and over $2500 spent.

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

It burns a quart of oil every thousand miles shouldn-??t be doing this

- Apache Junction, AZ, USA

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.

Car has been burning oil since purchased. Over a quart in 1000 miles. Engine rattled during acceleration and sometimes stalls at red light. Every time I take it into Kia they state nothing is wrong. They performed an engine cleaning around 80,000 miles but won-??t help me now that my car has 107,000 miles.

I have a kia Optima Hybrid that has an Open Recall for the engine according to Kia's website' which they failed to address or informed me of it needing it on 07-30-2022 which was installing the KSD update for the engine. The engine started knocking on 09-12-2022. The informed me that they do not make the KSD sensor update available to customers anymore since it is passed the campaign in dates in 2021, and that is why it was not installed. Although the owners site shows the recall and asks if I want to make and appointment for it. They are doing this with multiple owners. I am also curious as to why my car doesn't show this recall on here and it shows on Kia's owner site as being and open recall along with another recall. Kia case #15050283

- Atlanta, GA, USA

This car has developed P0010 code which stands for "A" Camshaft Position Actuator Circuit/open bank 1. Car idles roughly, shifts weirdly and has less power than before. I found that there is a TSB from KIA for the same issue but only for cars made in South Korea in 2016, mine was built in Dec. 2015 in Georgia plant so it doesn't qualify for this TSB and I'll have to pay out of pocket to fix this issue.

extreme oil consumption. Burning oil like crazy and occasional knocking

- Fort Worth, TX, USA

My car was just confirmed by the dealership it is burning 2 quarts of oil every 1,000 miles. I am consistent with getting oil changes, and just recently, my check oil light would start flickering when I was needing an oil change. It slowly started happening sooner and sooner until the repair shop recommended me to go to the dealership. I was told by the receptionist that this issue did not involve my warranty (which conveniently just expired May 2021) and that I would get my engine replaced if the Oil Consumption test failed. I just brought it in for part 2 and was told this was incorrect and all the repairs would be 100% my responsibility. The service guy told me to constantly add more oil, and if my engine fails CATASTROPHICALLY, Kia might step in to help. I am afraid to drive my car and feel like no one is stepping up to help?!

- Columbus, OH, USA

My oil light would flash on when coming to a stop. I was notified my car was low on oil my last oil change. However I was not made aware as to how much. About 2000 miles afterwards when checking the oil it looked to be empty. The oil light would again flash on when coming to a stop but then go back off seconds later. The dipstick was dry. I added the appropriate amount of oil to show in the safe zone on dipstick and again about 1500 miles later the oil light is flashing on when turning/stopping. Separately, the headlights have randomly turned off while driving at night and set on auto on multiple occasions.

The contact owns a 2016 Kia Optima. The contact stated that the vehicle was consuming an excessive amount of engine oil. The contact stated that the oil level warning light was illuminated. The contact also stated that upon depression of the accelerator pedal, the vehicle would independently enter Limp Mode with the check engine warning light illuminated. The contact had the vehicle towed to Quirk Kia Manchester (1300 S Porter St, Manchester, NH 03103) where they initially updated the knock sensor. The contact stated that the failure persisted and the vehicle was towed back to the dealer where the knock sensor was replaced; however, the failure persisted. The contact then took the vehicle to KIA at Nashua (107 Daniel Webster Hwy, Nashua, NH 03060) where he was informed that engine oil had entered into the cylinder head and damaged the spark plugs. The contact was provided an estimate for a new engine. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 76,000.

Engine has no leaks but is consuming oil at an alarming rate. Oil must be added every 3 weeks

- Jacksonville, FL, USA

We're experience excessive oil burning. The oil is not leaking. Internet searches have led me to many others complaining of the same issue. The engine is at risk of seizing. This can cause accidents if it happens on the road and expensive damage to the engine. We get the low oil indicator lamp and we check the oil levels, it's a good quart or so low. I don't believe we're even getting 1000 miles before the lamp comes on again. We do have the dipstick to tell us it's low. We have not yet had it to a shop for futher investigation to see if a sensor is involved or not, but our mechanics have said burning oil is a common issue.
