2018 KIA OPTIMA Engine Problems

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.

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

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...

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.

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...

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...

Excessive Oil consumption. Manufacturer specs 1 quart of oil to every 1000 miles to be added. I'm adding 1 quart for every 500 miles. Advised kia and had oil consumption test and was told nothing is wrong. I am having to add extra oil 0so engine does not seize causing a safety issue for people in car. The car randomly spits smoke out.

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.

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...

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

Excessive oil consumption 1-1.5 months approx. 1,000 miles into new oils change. It is available for inspection. Safety was put at risk due to not knowing there was no oil in my vehicle while constantly driving it as it did not display the oil warning sign on the dash board. The oil change dealership has confirmed an oil consumption issue two separate times. I am familiar with multiple people having this same issue with Kia and hyuandia vehicles. The dealership is requiring multiple steps to be paid out of pocket prior to using the full warranty i purchased to cover the issue even though they know what the issue is and how to fix it.

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...

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.

Engine failure just like all the other optima’s.

MY ENGINE STARTED MAKING A HORRIBLE NOISE AND JUMPIMG. THE OIL WAS JUST CHANGED AND IS FINE. HAVING TO REPLACE ENGINE AND ONLY HAD CAR 2 MONTHS

Knock sensor detection system. Driving and all the sudden felt like it hard down shifted… car behind me almost hit me. Engine light started flashing so I pulled into autozone and plugged it in and got the knock sensor code. It’s had oil consumptions issues for a while. It’s so dangerous to drive with limited power and speed

I purchased this vehicle used in April 2023 with 3,000 to go prior to another oil change. I returned home from a trip and the oil light would come on only while turning or braking. When checking the oil there was no oil in the motor. The reservoir was filled and two weeks in the engine is low on oil again. There are no leaks. The car jerks at lights as if it wants to stall out. I feel unsafe driving this car.

High injector fuel pump top engine mount went out at 68000 miles. It caused the vehicle to stall and lose power and basically cut the car off while driving.

-Knock Sensor Detection System - ECU Logic Improvement - I Was driving with my infant son in the backseat. I was going 70 mph when my car started rapidly losing speed. This happened again with just myself after receiving the car from mechanic. There was heavy traffic and I had to swerve to avoid being hit by an 18-wheeler. - I can see on the website where I received the car from, there is a recall for my exact make and model with the same code but they say there is no recall for my specific car. - The check engine light started flashing and Kia Systems starts talking.

Car smoking white , and driving slow after I hit a pothole when it was raining hard.

consistently getting oil changes. if the car doesn't rcvd an oil change before 3000 miles the check engine light comes on and then the light removes after oil change. in between the time period of getting oil changes it may run junky or you hear the catalytic converter trying to push air thru and it rattles.

My car engine burns oil EXCESSIVELY. After an oil change, 2 weeks later i had to put more oil in. The dealership is no help even with a warranty. The car burning oil is also causing other mechanical problems that are a hefty price that are only a temp fix. I have to put oil in every single week. 2-3 quarts a week. Due to the oil being burnt off, it has affected my spark plugs and has caused a misfire in the same exact cylinder for when it misfired for this same problem, a year prior. I took it to a kia dealership last year and they performed a combustion chamber cleaning ($650+) and it only worked for 3 months before my car was back to performing poorly due to power loss from misfiring again. This car has put me in a VERY TOUGH financial situation and the dealership...

IM UNSURE THE EXACT AMOUNT IT GOES THROUGH BUT IT SEEMS TO BE ALMOST 3-4 QUARTS BETWEEN OIL CHANGES.

Just Started Having Problems On It’s On The Car Only Has 38,000 Miles

My car is consuming 2 quarts of oil for every 1,000 miles. This falls under the oil consumption that needs a motor replaced and I am getting a run around from the dealership about getting it replaced. They are saying that Kia does not like to replace the motors and I'm better off trading it in. I bought this car intending on keeping it long term, not purchasing a new one. All of the regular maintenance has been done on the vehicle. I've been into the dealership a multitude of times a month due to issues with the car.

FIRST INCIDENT OCCURED WHEN I WAS DRIVING TO WORK. THE ENGINE MADE A NOISE AND LOSS POWER WHICH ALMOST RESULTED IN A CRASH. I CONTACTED KIA, THEY EXPLAIN TO ME THAT A KNOCK SENSOR NEED TO BE INSTALLED AND SOFTWARE NEEDED TO BE UPDATED. THEY INSTALLED IT AND RETURN THE CAR TO ME. NOW AGAIN WHILE I AM ON THE HIGHWAY I HEAR A LOUD KNOCK, LIGHTS FLASHING IN THE CAR AND THE CAR HAS LOSS POWER. I ROLLED OFF THE EXIT PULL OVER AND CALLED A TOW TRUCK. WHILE WAITING I CHECK THE OIL IN THE CAR THINKING MAYBE THE ENGINE IS LOCKING UP. THERE IS NO OIL IN THE CAR, WHICH IS STRANGE BECAUSE TWO MONTHS PRIOR KIA JUST DID AN OIL CHANGE. I HAVE DOCUMENTS TO PROVE EVERYTHING. KIA HAS BEEN THE ONLY DEALERSHIP THAT SERVICE THE CAR. THEY NOW BEEN IN POSSESSION OF MY VEHICLE FOR...

When driving this vehicle in heavy rain Critical Error Code P1326 comes on limiting the speed to 62 MPH and slow acceleration. This has happened 6 times. Two of those times I took to a KIA Dealer. One said they replaced parts and fixed - but still have issue and one did nothing but download software to get ride of code. The other 4 Auto Store has reset code which they should not be doing and sometimes say no. This has happened 6 times since I have owned the vehicle.
