My engine burns oil very bad. Black smoke comes out of my tailpipe and I burn through 5 quarts in less than a thousand miles. I just got my oil changed two weeks again and I just had to add more oil to my car bc it was empty. I-??ve had to replace the spark plugs twice due to soot build up. I can-??t afford a new car I-??m 17 and can barely afford the maintenance let alone a whole new engine. Have spoken to many mechanics and they all say the same thing -??it-??s a Kia it-??s gonna burn oil-?? ITS A KNOWN ISSUE. And yet Kia will not resolve it bc they don-??t want to spend their own money to fix their mistake. I got an estimate for a new engine which is basically crucial and it-??s over three grand. No matter where I take it everyone always says the same thing- to get rid of it before it-??s too late. But I simply cannot afford to do that and I know my car is not the only one with this issue so many other people with the same car/engine have the same issue. 2.4 L GDI !!!!! I wish someone would have warned me before buying Kia. A recall to fix this issue is needed now. I lose control of the speed sometimes. I will keep my foot at a set position on the throttle and the engine will take off because it-??s jumping to the usual power it should have. ( it has reduced power most of the time bc of the struggling engine) sometimes on the highway I-??ll get a sudden burst of power and I have to let off the accelerator. Not safe at all

I drove the car to the park about 6 miles round trip with family. I came back home and started having lunch for about 25 minutes. I then attempt to start the engine to go to my appointment but then car didn't turn on. On third attempt I had a weird noise coming out of the hood and I went back inside the house to get my gloves. When i came outside of the house, the hood of the car was in flames. I called 911 to turn off the fire. The car is now at a total loss.

I-??ve had the 2018 Kia Optima for a little over a year. I purchased it as a used vehicle. I-??ve noticed that the car is utilizing an excessive amount of oil. Each time I get an oil change for the vehicle I am having to purchase oil to refill the vehicle about 2weeks to a month after. I-??ve made multiple road trips where I-??ve gotten the oil changed before leaving and I drove around 350 miles; halfway through the drive the oil was half empty on the dipstick. The first time this happened I was unaware of this issue and when I arrived to my destination after around 350 miles of driving, the car had little to no oil. I will provide store receipts of each time I had to purchase oil for the vehicle. I will also provide service interval receipts upon request. Dates of oil purchase are as follows: 1.7/18/23 2.8/16/23 3.10/20/23 4.12/18/23 5.2/7/24 6.2/29/24 7.3/18/24 8.5/4/24 9.5/11/24 10.7/9/24 Service intervals for oil changes are kept up with every 3-5k miles and can provide maintenance receipt.

Oil consumption issue. My mechanic referred me to Kia because oil consumption. I would bring car in because oil light and no oil in car and had oil change only 1000 miles. Kia did 2 checks one at 1000 miles and one at 500 miles and oil consumption failed both times. Now I have to pay $686 for oil combustion cleaning even though I am being told this is more than likely going to have engine replaced by Kia because of known issues,

- West Melbourbe, FL, USA

It started with the car using oil but the mechanic could not determine where the oil was going. It quickly lead to the Cadillac converter going out with a host of other things that cost me over $2900 to fix. Which only lasted a few weeks and the last incident occurred when I was on my way home and it would not pick up speed at all and would stall. The first time it happened I was on the free way and it lost speed almost causing a semi to run into the back of me. The second time I was at a red light and when I tried to accelerate in speed and it stalled and then began to jerk before it would pick up speed. Each time the occurrence happened it placed my life as well as my families life in danger as it was sudden with no engine light or any other lights coming on. The last time it happened it left me stranded with a child, over 2 hours from home and in the middle of the night on isolated highway. Every time I would call KIA they would give me the run around on the issue and say it was due to my negligence but I beg to differ as I feel as if it is an engine error on the manufacturing. Please help. Currently the car is sitting in my yard and I can not afford to keep paying for repairs due to a faulty engine that they refuse to fix.

My 2018 Kia Optima experienced an oil consumption issue. After awhile out of nowhere my vehicles oil light kept coming on. There was zero oil in my garage. Unbeknownst to me It was burning oil due to this oil consumption issue.I took it to multiple mechanics all which told me that this issue is a known issue and would eventually blow the engine, which is exactly what happened. I reached out to Kia in person via dealerships over the phone via their consumer line and they went out of their way to tell me all the reasons why they could not replace the engine. I have spent enormous amounts of money on rental cars and Ubers and Lyfts to get to work or appointments just to Because of this issue. I was referred to this organization by the Ga consumer bar help line.

- Avon, IN, USA

My vehicle is constantly running out of oil within a 30 day period and I constantly getting an oil change. I was advised to get an oil consumption test at the dealer and was out of oil in 3 weeks. I was told that I have a warranty, however, it's only if the rod bearings are an issue. I think my engine should be replaced without paying a $300 diagnostic fee that might get refunded without an exact time frame.
