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’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.

Took my vehicle for an oil change next day my vehicle was not working well stopped on me could start didn’t want to do damage so I stopped driving and had it told to a shop found out there is metal in the engine.

Code p-030300 was detected when doing a diagnostic on my car when the check engine light came on. It is a cylinder 3 misfire. When the car comes to a idle the car starts to shake roughly. I took it to the kia dealership I bought the car from and they told me I would need a new engine and not to drive it. Thankfully nothing bad happened while my baby was in the car. I drove it home and stopped driving it completely once the issue occurred.

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,.

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.

The contact stated they were filing for their sister who owns a 2018 kia Optima. The contact stated that the oil seemed to be burning at a fast rate due to them having to add oil every 2-3 weeks. There was a warning light that had illuminated however the contact was unsure of what the light implied. The contact stated they were told the vehicle continued to burn oil at an excessive rate even after receiving a repair. The vehicle was taken to the dealer where it was diagnosed that the valve cover gasket failed. The valve cover gasket was replaced as the first initial repair. The vehicle was taken to an independent mechanic after realizing the failure persisted where they diagnosed that the engine had an oil leak burning approximately a quart of oil within a couple of weeks. The mechanic stated that there was a chance the engine may need replacing however the diagnoising had not been officially confirmed. The vehicle had not been repaired. The manufacturer was not made aware of the failure. The failure mileage was 98,000.

Indiana - car in reverse in driveway and started shaking. I turned car off and back on and it drove normally. The next day, I put the car in reverse and the shaking started again and check engine light illuminated. This car has a history of burning oil and we constantly have to add oil between oil changes. Car is at andy mohr kia dealership at this time where we were told that engine would not be covered by warranty because we are second owners. Mileage of car is 62,000 miles.

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.

My engine started leaking oil from the inside and all of a sudden my car started shaking out of nowhere.

1- my 2018 kia Optima engine seized while driving on interstate 64 west -had the car towed to a mechanic (j team auto repair) and was told me to contact kia because after replacing the spark plugs and coils and knock sensor there was still no compressing in cylinder 4. My life and safety was at risk when my engine blew out on the interstate. When I went to kia dealership they confirmed that my VIN number was included in the recall and in the class action lawsuit. Customer support told me since I wasn't the first owner of the car they weren't required to honor the recall -I asked why I was never informed they told me I bought the car as second owner my 60,000 warranty has expired and the extended warranty for engine doesn’t cover compression issues - its stated on the NHTSA website that they are required to send notices to all owners. When I contacted (escalation case specialist) with this information they said the extended warranty only covers the rod bearing connectors, and not compression. Completely contradicting the first call I had with another employee at kia. Kia is deliberately keeping people in cars with engines that were manufactured improperly. I had the ksds update-it takes more than reading engine codes to get to the bottom of things. Compression is part of the engine block. Prior to the engine failure, my kia Optima, was constantly burning oil.

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.

I took my vehicle to jenkins kia-ocala back in March and may of this year for my check engine light lashing on and off and acceleration issues, car shaking, and excessive oil spilling into my spark plugs. The 1st time I took my vehicle to this location I was told to "drive my vehicle until it no longer had any motor oil to "allow the motor to lock up" to then be approved to have my vehicle engine approved under the gdi recall". I expressed my great concerns to the employees about that statement and also reported the issue to bbb. I recently took my vehicle to kia jenkins Dec 8th for the very same reason only this time I showed them paperwork from a different certified mechanic who indicated that I have an internal engine issue. Kia then created a tech line case after seeing the paperwork showing I took my vehicle to a different shop. Over the course of holding my vehicle for over a week without any answers I was able to contact kia consumer affairs who offered to repair my vehicle under good will. Kia jenkins employee told me over the phone that my car will not be approved to be fixed due to the high mileage on my vehicle. I asked them what the miles has to do with my safety and the volunteer payment that kia consumer affairs is willing to pay as that is not a reason to deny a good will payment. The employee proceeded to state its not going to be approved and I expressed I felt this is due to my previous report to the bbb. 12. 8. 23 I received an email from kia consumer affairs stating the good will case has been declined due to my vehicle not being "routinely maintained" according to the feedback from jenkins kia service department. I went to kia to pick up my vehicle. I proceeded to question what maintenance was recommended that they are claiming I did not complete as they never advised me of any issues with my car pertaining to their new list of things, they added on the invoice of things they claim I denied.

I have had this car in the shop multiple times for a engine light that kept coming on, they would reset and say they couldn't see anything wrong. Well my car died in Dec, it made a noise and would not accelerate. To avoid any further issues I parked it and had it towed to a dealership. They told me the catalytic converter had come apart taking out the turbo and it would cost me $6k to fix. I decided to see if I could find parts cheaper, to find no one anywhere in the us or canada has a converter for this car and it seems many dealerships have customers on waiting lists to get one, so I am now wondering if this is in fact a pretty large problem kia is not addressing. I called kia and got a very canned answer that parts were hard to come by right now and it could be up to 2 years to get the part. So I am now paying for a car I cannot drive and have no idea at this point if I will ever be able to drive it. I am hoping you are able to do some research to see if this is a bigger problem that nobody seems to be talking about. Thank you.

Was driving on the interstate. The only light on was the abs light and the car started smoking. Had to come to a stop as they were sparks coming from out under the car through it into park at around 15 mph steel jumped out of the car and within a minute the car was fully engulfed in flames.

I purchased my 2018 kia Optima directly from the dealership, brand new. I've had the vehicle since then and have followed all of the warranty guidelines and only went to them for oil changes & other maintenance issues. Since February 2023 I've noticed where I've been having oil loss, but no sign of an oil leak. When I first noticed this, I would take a turn and my oil light would come on. I'd check the oil and it'd be low so I would refill my oil. However, this was happening 2 months after my last oil change which wasn't normal. I took the vehicle to kia and they did an "engine consumption test" where I had to drive for 1000 miles with a seal on the drain plug. After the 1000 miles, I came back and I was only 1/2 quart low. According to kia it didn't meet the guidelines for engine replacement so they topped off my oil and I left. About 2 weeks after, my oil light came back on. I went back to kia and spoke with the shop manager who stated I was 3 1/2 quarts low! he added oil to my engine and we did another round of the consumption test. When I came back in after that, I was 2 quarts low so that meant I qualified for a "consumption cleaning". They kept my vehicle overnight & I had to drive another 1000 miles. When I came in after my 1000 miles again I was only 1/2 quart low and therefore kia said there wasn't an issue. I've reached out to multiple auto repair shops who state it is a kia problem, that the engine is using it and processing it out of the exhaust. I don't know what else I have to do in order for kia to honor the 20 year, 200k warranty. I have all documentation for all of my oil changes and from the consumption tests also.

Car burning excessive oil in engine. 2 quarts every 1,200 miles.

Car will not go pat 60mph and I haven’t had this car just over 6 months. And the camshaft sensors are gone out. Smoke comes out the pipe when mash on gas…. It is really a bad vehicle. And southeast auto refuses to fix it. I really honestly think the motor is bad in it. Because I been having issues with it since I had it.

My engine is under a million mile warranty because it burns 1qt oil/1,000 miles. My engine burns just under 2 quarts of oil about 800 miles. For long trips, this is very unsafe because my engine is going seize or burnout on the highway at some point. This will put my life and possibly that of other drivers at significant risk.

Purchased my car in June of 2019. Ive scheduled regular oil changes and maintenance until June of 2020 where the engine light began to flicker and the car would shake. I took to koons kia owings mills MD and it was repaired. Next year same thing. Oil compression issues all year round where I have to keep putting oil in. Now my car starts and shakes violently. The kia service modurator on the car indicated there were an engine issue. I cannot keep dishing money into this car with so many recalls (current fuel pump recall and anti theft issue) is also included. Please help.

I'm reporting these issue pertaining to the engine within the first 3 weeks after the engine replacement recall was serviced and completed. The vehicle was exhibiting the same defects and major health and safety hazards as before the new engine. Intermittent engine failure, even worse, while I was trying entering the hwy at speeds of 45-50 miles it jerked very violently and loss total power while vehicles were behind me nearly rear ended. Prior to this I reached out multiple times to have it serviced at again. The original service department didn't respond, so I called other service departments and was told it needed to be serviced by the original dealership/service department that replaced the engine. I had the vehicle in normal working conditions a few days before it began exhibiting the same problems as before the engine replacement. It was in operable condition but still stalling and refusing to crank unless primed, until it ultimately just would not crank at all and is back in the same condition it was before the new engine but it is not locked up currently. The time frame and milage between first experiencing the issues to now, March 2023-64745 started shuddering, loss of power while driving, but would crank right back up without issues. Happened a few times, charged up battery thinking is was am electrical issue. April 2023 more frequently the issues occurred, still same severity levels. May 2023 began happening every time at an idle, whether I was at a fast food in drive through placing an order, or to wash the car. Every time at an idle this would happen, and would take a few times of trying to start the vehicle and after about 5 seconds of cranking it would catch and work. I began placing the vehicle in neutral while at idle and it would assist in the stalling out sometimes. After a few days of this it refused to crank due to the engine locking up. Milage at this time was 68048. Aug 2023-new engine, drove about 2k miles-70207 current.

My vehicle is under a engine / oil consumption recall, I have contacted kia multiple time in regards to this issue as the vehicles are having engine fires due to this. I was advised by kia that my vehicle is under recall and has lifetime warranty but they will not fix or swap the motor until it goes out. This is a huge safety risk I am literally scared to drive my vehicle due to not knowing if the engine is going to go out at anytime or start on fire in the middle of the expressway.

Vehicle is burning excessive amounts of oil rapidly. Date of purchase: 04/13/2023 - mileage : 94,000-96,000 oil light and engine light began flashing about 1-2 weeks after purchase, then went off after first oil change. Noticed burning smell on occasion. First oil change 05/23/2023 - mileage: 98,045 mechanic reported no oil in vehicle. Traveled out of town, checked oil. No oil in vehicle upon arrival. Second oil change: 06/19/2023 - mileage ~99,641 mechanic reported no oil leak. Checked oil: 07/18/2023 - no oil in vehicle, mileage: 100,790 having to schedule an oil change before future date and mileage listed below. Next date of oil change: 09/17/2023 - future mileage: 102,641.

Vehicle stated was consuming a large amount of oil by burning it. This was able to be determined by the lack of oil or residue anywhere on the engine or engine compartment. It was then taken to the dealership were it was determined an engine oil consumption test needed to be done. The test was done and was determined that it needed an upper engine combustion cleaning to correct issue. The vehicle was then scheduled to have this procedure done. Upon completion of this procedure the vehicle continued to burn oil as it could be seen out of the tailpipe upon acceleration. A second oil consumption test was performed and was found to be within dealer specs of acceptable oil consumption at 1qt per 1000 miles. When the next oil change was done by an independent garage, it was noted that the vehicle was now leaking oil from what appeared to be the oil drain plug. The dealer was then informed with pictures of the oil leak. The vehicle began leaking more and more oil now at a rate of 1/2 qt a day as of writing this the independent garage inspected again and found that there was a crack in the oil pan just to the side of the oil drain plug. After doing some research it appears to be a very common problem. The vehicle in question is supposed to be taken into dealership to have the issue checked out on the 4th of October 2023. Todays date is 9/26/2023.
