2015 KIA OPTIMA Engine Problems

Engine spontaneously seized/locked while driving. No check engine light on previous to this happening. Left me stranded in middle of busy road.

I have a 2015 Kia optima bought in July 2023 from a used dealer. This is the 4th Kia my family have owned. Prior to purchasing I ran a car fax and checked for recalls. The dealer where I purchased it at also check for recall.. I also checked again today on your Kia website for recalls and the only one listed is the newest one concerning the fuse which I also received a letter in the mail on Monday. The car currently has 131,000 miles service has been maintained. On [XXX] the car just stopped running going down the road no check engine or any warning that something was wrong.. I had it towed on Tuesday to a local shop who then told me it needed to go to the Kia dealership which is about 20 miles away… I had to have it towed again.. once at the Kia...

Engine started knocking

Driving on the highway at 60mph and the engine just shutdown and the car turned off. Fortunately, I was able to get onto the shoulder without incident. No warning lights came on until the engine shutdown. Tried to restart the engine after letting it sit for a few minutes, would not start again. Had the car towed to a local mechanic and they discovered that the engine seized. Hoping the service contract I bought when I bout this car used in November will cover the engine.

Drove this 15 Kia Optima on the highway when all of a sudden it lost power and died. There was no lights or symptoms prior to this happening. The vehicle ran as it should up until the other day, the Engine had no codes or lights on in the vehicle.. Then without any signs at all the vehicle stalled and almost caused an accident on the highway and the would not start. Barely made it to the breakdown lane. We had it towed to a shop and We spent some time checking the Kia over to find out the starter had melted. We installed a new starter and now the engine has a very loud knocking sound that was never there before. Based on reading the safety recalls and bulletins on this Kia and issues surrounding this vehicle online, we should meet the criteria for a claim. Can you help...

I have 3 issues currently going on with my 2015 Kia Optima. The first is the Oil Control Valve. This is supposed to be covered under my extended warranty that I pay for. If I didn't have the extended warranty I would be responsible for putting a new engine in a car with less than 60,000 miles on it. However, it will take time for the adjuster to come out and then to decide if the entire engine should be replaced which would then take even longer. The second issue is the O2 sensor which is part of the exhaust. Apparently in a care with less than 60,000 miles on it it's not unusual in the Kia Optima for this to go bad. Kia knows this is an issue but hasn't done anything about it. Lastly, the Stop Module in the braking system needs to be replaced. After hitting my...

The car started making a noise and oil was just changed the prior month no leaks or anything and know it makes a noise and the engine light is on

The contact owns a 2015 Kia Optima. The contact stated that while driving 30 MPH, there was an abnormal smoke odor inside the interior of the vehicle. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who determined that there was an oil leak in the engine compartment. The vehicle was not repaired. The vehicle was then taken to the dealer, who diagnosed a failure with the engine, determining that the engine was consuming oil abnormally quick, and the engine might soon need to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was unknown.

I received a safety recall notice in November 2023 stating that there is defect with Hydraulic Electrical Control Unit (HECU) in my car that can result in an engine compartment fire either while I am driving my car or when it is parked. As of April 2024, I am still waiting to be notified that the part to fix this issue is available. This delay is putting my life and my children's lives at risk every time we drive in our only car, as well as the drivers around me if my car catches on fire when I am near them. In addition, this issue puts our home, as well as our neighbors' homes, at risk of catching on fire since I am not able to park outdoors away from other cars and structures as was recommended. In the past few days, I have felt a difference in my car's...

Driving to work, that is less than 5 miles, started to hear a noise then car just stopped, called roadside assistance , towed to dealership. Had to wait for their diagnosis… I should be under my warranty. I have 44,400? Miles so under 100,000 miles. Has 10 yr warranty also but is 9 years old. Car paid off. They diagnosed rod bearings out and need a new engine—- m/b 6700.00 to replace engine. It should be under warranty- they said they had 4 recalls on that car/ make & model. I was never NOTIFIED so that is now supposedly null & void my warranty because they said my problem.

I was driving in downtown Gilbert when I pulled up to a red light. My car would not inch forward when taking foot off brake. I then had to put my foot all the way down to get my car to drive. When taking a turn my car would run perfectly until I stopped. Then we pull up to parking garage and the car just stops without while in drive so I put it in park and then turn it off and then back on and it works again. I had the alternator, battery and starter checked and they were all good no issues so why am I having electrical problems with my vehicle Kia needs to fix this.

Loss of power to engine when trying to increase speed to turn into traffic/getting onto the highway and constant severe engine knocking noise. I have to use hazards when turning into traffic/merging onto highway because the vehicle takes too long to catch up with the speed of traffic. It also has a problem with excess oil consumption, needs to be refilled every week and a half to two weeks. Bremerton Transmission has provided an inspection and a Diagnostic Trouble Code (DTC) P1326 (Knock Signal Range/Performance). The oil consumption has been an ongoing issue since I bought the car in February of 2022, only getting worse. The rest of the issues have been escalating problems.

This owner has a 2015 Kia Optima. Car started tapping without warning. Checked the oil level and it was out of oil. No warning at all. Had maintenance on car when due. Motor is completely gone. I have had this car 3 years and it only has a little over 60,000 miles on it. This vehicle needs to be repaired @ no expense to me because the 10 year or 100,00-mile factory warranty still remains.

The last recall that was fixed is occuring again . Car loosing power warning signal popping up Sometimes smells like matches after parked.

HI, I own a 2015 KIA OPTIMA. Sometimes when I drive it, I get a burning smell from the dashboard/engine after driving it after a while. I received A KIA recall notice regarding an electrical short circuit in November 2023. The notice said that the electrical short circuit could cause a fire, which I think is the cause of the burning smell. When I called KIA to bring the car in, they said there is no remedy to fix it yet. So I receive the notices in November 2023 and at the time of writing it is March 5th 2024, five months after and KIA does still does not have a remedy to fix the problem. I think this is a major safety issue that is not solved in a timely manner as there is potential risk of fire every time I drive my car. I hope NHTSA can step...

While driving on the busy interstate my husbands 2015 kia optima stopped working while driving. This could had gotten him killed!!!! It was taken to a auto shop where they said his engine seized and it was going to be $8000!!! There was nothing wrong with his car prior, it just started making noises and he was on his way to get it checked when it stopped. The car was up to date on all oil changes/etc.

Our. Vehicle is under 90,000 miles and the engine is going out on it This is under 10 years on the vehicle and an engine shouldn’t be going out so soon.

The contact owns a 2015 Kia Optima. The contact stated while driving 70 MPH, the vehicle jerked and then stalled. The check engine warning light was illuminated. The vehicle failed to accelerate over 60 MPH. The contact stated that the failure had occurred four times within the past two years. The contact stated that the vehicle had been repaired twice by another Kia dealer and the last two failures the vehicle was repaired by Freddy Kia.

The knock sensor had been replaced four times. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 115,000.

I got my engine replaced, after using 100 miles on the car I checked my oil there was no oil in the car, every time I try to go over 45 miles the car hesitates to speed up. I am constantly checking the oil weekly, the engine still makes the knocking noise, never again will I buy a KIA vehicle again

3 months prior to my car going into limp mode I had an incident where I was on the highway and had to come to a stop of major traffic and suddenly my car cut off out of nowhere. I got it to crank after putting it in park, but it was very scary being on the highway thank God it was traffic to where cars wasn't going so fast. Fast-forward to my recent incident to now my car's now in limp mode (MIL) same situation different times was getting on the highway and started to pick up speed to accelerate to 60mph my engine light started to blink Non-Stop and here I am again in a terrifying situation to where I have to get back off of the freeway and I also was on my way to work now having to call in and praying and hoping nothing happens...

Engine failure I am writing to express my serious concern regarding the defective and unsafe vehicle that I purchased from Kia Motors. It has come to my attention that Kia Motors is selling vehicles with known defects that can potentially cause harm or even death to its customers. I demand immediate action to rectify this situation and ensure the safety of all Kia vehicle owners. On [XXX], I visited a Kia Motors dealership to address a recall for the ksds engine on my vehicle. I was told the service was complete and I retrieved my vehicle. However, in December 2023, my vehicle suddenly stopped working in a busy intersection without any warning. I had my vehicle towed to a Kia Motors service center, where I was informed that the engine had failed and needed to be replaced. A month later, I discovered that the ksds recall repair had never been...

I heard a noise and pulled over to take a look at it and noticed fluid was leaking. Then the engine wouldn't start. I had the vehicle for about 2 weeks before this happened I had a mechanic diagnosis why it wouldn't start and he said he found a crack in the lower end of the engine crankshaft gridle and now yhw engine needs to be replaced.

Only 77k miles, all recalls addressed. Engine stopped going about 45 mph, was able to coast into a gas station luckily. Towed to a Kia dealer where it's been for 3 months waiting to be diagnosed. Kia won't reimburse towing or rental until it's diagnosed. I paid $350 to get it diagnosed. They are saying it'll be another couple weeks before that even happens. I can't afford constant rental car. This has been a nightmare.

I have experienced several issues with my Kia. I have replaced catalytic converter (direct fit), and the valve covering gasket. However, the engine reports issues every other month. The dealership dismissed everything stating that the engine is fine. But wherever I take the car to get an oil change, they say I need to contact the dealership. I have been consistently managing my car maintenance but it does not help.

When i was in the highway, the car starts shaking and the engine light turned on. Parked car in the nearest rest stop and I immediately smell smoke coming from engine

The engine had less than 40K miles on it and a total engine failure occurred due to blown head gasket. They replaced the engine with another used engine and this one started smoking and nearly caught on fire, resulting in another total engine failure. They are now trying to install an engine with an unknown amount of mileage on it as the replacement engine.

I purchased my car in 2015 at 23k miles, now we're at 86k miles and I'm experiencing issues. How is there a recall for this car but no remedy yet when there is a high risk of fire? Shouldn't there be a resolution for this safety concern? I noticed my car in 2022 would smoke here and there when driving, and I would smell burning. I took it to my mechanic and he changed the head gasket, and the smoking stopped. There is residue on my engine from a leak from the oil. My mechanic at the time told me I might still smell burning oil just due to that. As time went on things were fine but a year later, the oil smell came back stronger. I notice it only on longer drives, so I do believe my car is leaking oil. Also, the amount of time I've changed...

HECU has been replaced by kia dealership but I paid although all recalls performed are free.

Driving my car on a busy highway. Car completely stopped. Putting myself in extreme danger! Tried having the car jumped off and that did not work. I waited hours on a tow truck on this busy highway! Had the car towed to a mechanic and was told that the engine has blown. Called manufacturer and was told that my vehicle was a part of the class action lawsuit, but I failed to comply with the recall. Well, I am the second owner and HAD NO IDEA ABOUT THIS RECALL!

While I was driving the car just stopped accelerating, the dash was still lit but the car went completely out would not turn over or restart,

I bought a 2015 Kia optima in February of 2023. In October the engine completely seized with zero warning. The vehicle was always properly serviced while in my possession. The engine seized and the car went into limp mode during the first snow storm of the year on one of the deadliest mountain passes of North Idaho. I, a young woman, was stranded almost an hour outside of town on the side of a freeway on a mountain during a snow storm. The power in my car shut off so I was unable to use the heat system. I waited approximately 3 hours in these conditions for a family member to arrive. I then had the vehicle towed 40 miles back to town and have been without a vehicle since. Kia USA has only offered $40 a day in rental reimbursement to assist with the situation. However, due to my...

There seems to be some oil burning off when I drive. But none leaking on the ground. My car is consuming oil. Also if I press the gas to speed up, my car will stall a bit and then some black smoke will exit my exhaust.

On Nov 22 2023, while driving my car the engine light came on and within 10 mins the car shut off while moving in traffic. Using the residual speed I was able to safely pull over and after multiple attempts to restart, there was smoke coming from the engine. Had the car towed and approx 3 weeks later (multiple attempts to contact the dealership and reaching out to the manufacturer) the dealership accepted the car to try to assess the issue. When this happened, it was only then I was aware of the recall which seemed to be related to this exact issue. The manufacturer and dealer have then slowly worked on trying to resolve the issue. This complaint is solely for informational purposes at the moment as it's been almost a week since I was able to contact anyone. My car is currently at the dealership with no feedback...

Engine is using excessive amount of oil. It has been changed on a regular basis have documentation bought the car new. I have noted that there are several complaints of the rings going bad in this model engine of the rings letting oil blow by. When is the NHTSA going to demand a recall as this can cause the motor to blow up and causes much more carbon emissions. Please make this a priority recall before more people get hurt and the emissions put out more pollutants/carbon in the air..

My car has been consuming lots of oil. I took it in for an oil change and while test driving two of the mechanics stated the oil light came on and it ran out of oil on the test drive. Instead of saying anything about a possible issue with the engine, they went ahead and put oil in it and sent me on my way. Since, my car is still consuming loads of oil. I've taken it into the dealership several times for the same issue and each time they told me they can't do anything about it until it runs out of oil. One person advised to not put oil in it. Now the engine light came on, so I took it in again and this time I was told the cylinders have gone bad and one person that worked there said to let it run out of oil,...

1. While stepping on the brakes my car has revved up as if I was pressing the gas. So I let my foot off the pedal and pressed the brakes again. This happened 2 times that week. And another time while I was coming to a stop light as I pressed the brakes, my car revved up but didn’t actually make my car speed up. I had to press the brakes again for it to stop. 2. My battery was smoking and I replaced it. 3. My car is consuming oil. The dealership did a series of oil consumption testing due to the exhaust leaving extra carbon residue on my car. They said it was fine but I don’t think they solved the issue.

The contact owns a 2015 Kia Optima. The contact stated that while driving at approximately 40 MPH, the engine seized. After restarting the vehicle, the vehicle shut off. The vehicle was towed to the local dealer, where it was diagnosed that the engine had seized and needed to be replaced. The contact was informed that there was metal in the intake and exhaust cam shaft. There were metal shavings in the oil. The contact was also informed that the pistons were off by twenty-four degrees. There was an indication that cylinders #1, #2, and #4 had misfired. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 102,589.

I have a 2015 Kia optima GDI, I never had any issues with this vehicle and I kept with my oil changes, but one day in November I was driving on the highway doing about 65 my car shut off in the middle of the highway, I only had the car for 2.5 years. I took it to advance auto got the battery and alternator checked which said that I had a bad alternator, and a code of p1326. The alternator was changed but I am still not able to drive my car, I took it to my local Kia dealership and hopefully they’ll be able to replace the engine. I never had any issues with this car but paying on a car that I can’t drive is very stressful. I will never buy a Kia vehicle again

The engine is being to make a sound. When I checked it’s the rod knock. In the end of September my wife drove the car to work where it stopped working. That’s when I heard and seen what it was. It’s my understanding that many optimas have been having engine problems. I was told to take it to a dealership and Kia would fix it that there was a recall. Please let me know if this is true or any help you can provide.
