2017 Kia Optima complaints

I was driving and as I was going to make a left turn, the steering wheel forced itself to the right and locked. And the whole car completely shut down. So I had to slam on my brakes as they were also locking on me.

The contact owns a 2017 Kia Optima. The contact stated that while attempting to start the vehicle, the vehicle lost motive power with no warning light illuminated. The vehicle was towed to an independent mechanic, where it was diagnosed and determined that the engine had failed and needed to be replaced. The vehicle was not repaired. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 80,000.

Failure of Flexible Steering Coupler, part of the Motor Driven Power Steering. This flexible coupler deteriorated noticeably over about 6 months time. Currently steering is very erratic with crunching sounds when turning wheel. This is a serious safety concern. I had the steering and suspension inspected at an official PA state inspection station (annual requirement) and was assured that the mechanical under car parts are all good. HAs never needed any repairs in this area, not even a wheel alignment. I am the original owner and the vehicle has been well maintained. Vehicle currently has 141,000 miles, mostly highway driving. KIA advises that there is no recall and no warranty repair available. I believe this is a design defect and safety issue.

I was driving on the highway, the check engine light started flashing and the car lost power. This created a very dangerous situation because I could not go the speed limit and could not get off the highway since I was in the middle lane. We went and had the check engine light checked and were told the code was P1326.

Unknown Oil consumption Spark plugs need replacement about every 500-1000 miles. Also needs oil every 500-1000

I was driving on the highway and randomly my car started to shake very badly and i couldn’t go faster than about 30 mph. My engine light didn’t turn on until i turned the car off and back on after finally making it home after almost getting hit by cars trying to make it back home. I sent it to get looked at and they said that it’s misfiring pretty severely and that kia had a recall on an engine/motor awhile back for my car and to take it to a dealership. I contacted KIA customer care but the only recall I see when I look up my VIN # is for the trunk recall.

There appears to be an issue with Kia USA regarding an oil switch fault that the company may be aware of but has not addressed through a service bulletin. We own a 2017 Kia Optima with a 2.4L engine and 84,000 miles that has recently started experiencing an intermittent oil pressure light. Thinking the issue was covered under warranty, I took the vehicle in for repair, only to receive a quote of $6,000. The faulty switch had pushed oil through the wiring harness, contaminating the powertrain control module and fuel injectors. I have found information indicating that Kia issued a service bulletin in April 2022 for the same switch used in the 2.4L issue affecting 2015-2018 Kia models with 3.3L engines. However, when I provided this information to the dealer, they insisted the switch in my Optima was different and not covered by the bulletin. I have repeatedly requested the part number for the faulty switch referenced in the bulletin, but have not received a response from the dealer or Kia corporate. The information I found on-line is that the switch in both motors are the same switch. I understand that if this issue is not addressed early, the repair cost can reach upwards of $7,500. If Kia had proactively notified 2.4L owners about the switch issue in 2022, my problem may have been caught and resolved before the extensive damage occurred. Furthermore, if the faulty switch was used across multiple Kia models during the same time frame, the company should have included those veh

1.) What component or system failed or malfunctioned? Engine failure due to excessive oil consumption and/or a malfunctioning Knock Sensor Detection System (KSDS). •The engine failed at only 50,000 miles due to internal issues. •The KSDS system triggered a flashing check engine light, but Kia refuses to cover the repair despite known past issues. •Kia engineers and the dealership confirmed the engine failure but are denying warranty coverage. ➡ The vehicle is currently at the dealership and available for inspection. 2.) How was your safety or the safety of others put at risk? •A flashing check engine light appeared, indicating possible catastrophic engine failure while driving. •Loss of engine function on the road could have led to an accident. •The KSDS system was designed to prevent this type of failure, but it failed to stop the damage in time. •If the engine had completely failed at highway speeds, it could have created a dangerous situation. 3.) Has the problem been reproduced or confirmed by a dealer or independent service center? ✅ Yes, the issue was confirmed by the Kia dealership. •The dealership confirmed that the engine has failed and needs to be replaced. •A tech line case was opened with Kia engineers, who confirmed the failure. •Kia refuses to cover the repair, claiming it is a "top-end failure" instead of a "rod bearing failure." 4️.) Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? ✅ Yes, it was ins

My Engine is burning a quart or more of oil a week. Since my last oil change I have put in 15 quarts of oil. I called KIA service department and they said there is nothing they can do unless my check engine light is on.

Yes, the issue has been confirmed by Kia. They acknowledged the high oil consumption and indicated that the engine requires a rod bearing replacement. However, Kia does not want to fully recognize the problem. I have taken the car to another mechanic who confirmed that the ignition coil has burnt on cylinder number 3 and identified it as an engine failure along with the high oil consumption.

The contact’s daughter owns a 2017 Kia Optima. While the contact’s daughter was driving at an undisclosed speed, there was a loud rattling sound coming from the front end of the vehicle.

A auto repair shop said my Kia Optima has a bad knock sensor which is a common problem with those cars. My safety and others was put at great risk when I suddenly lost power on the freeway Problem was confirmed at an independent service center Has not yet been inspected by manufacturer Warning message came up at the same time as losing power

Took the car to the dealership to diagnose an issue that I know Kia has a settlement for which is the engine class settlement and the dealership is trying to say the cause of known issue is from another source so they do not have to cover the cost of a replacement engine. The dealership is saying my option is to pay 8-10k for a new engine when it should be covered under the lifetime engine warranty which they confirmed I have. Engine light popped up the day of taking it to dealer. The engine has the possibility of seizing putting the driver or others at risk of serious accident.

Drivers side seat belt will not click into latch

Engine is burning 2 QT of oil every month and burning it in under 1000 miles. Kia dealership says it's a common issue but can't help me until the engine seizes up. The car has less than 85k miles on it. How can this be a common issue but they can't fix it till the engine dies? What if the engine dies out of warranty? Then I'm out 12k for a new engine that will die in 80k miles. This should be a recall.

Car engine stuttered when turned on, then after a moment smoothed out . I noticed some looseness in response in the steering wheel while driving forward, after a short period of time driving the antiskid symbol and the EPS symbol came on and I lost power steering. I turned off the car and turned it back on . The emergency symbols were gone and the power steering was OK. I headed back home and the symbols came back on and lost power steering again after driving about 3 blocks. I repeated turning car off and on to get home.

The KSDS in my engine is causing engine failure due to the dealership failing to fix the problem when I first experienced stalling, lagging and misfiring of my vehicle, which would often make it shake and I would have to turn the car off and reignite it, sometimes more than once. My safety is at risk when driving, because the vehicle will lag while trying to accelerate in traffic. My mechanic researched the issue and found the recall and Kia said they fixed it when it was issued and they didn’t. My CHECK ENGINE light is flashing now and it continues to lose power. I have contacted Kia about the issue and I’m waiting on a response.

The engine Is losing oil. Taking it to KIA dealership and other repair shops around our area and she has to have her oil changed every thousand miles because the oil is going somewhere but they don’t know where because there’s no leakage anywhere. I see there’s 100 of other complaints about this key should be responsible. Please indicate what we can do about this doesn’t have that many miles on it.

Driving highway speed (75) after work may 23rd 2024 when my car just randomly stop accelerating and I pulled to the side of the highway and I heard a weird engine knock sound coming from engine . I turned the vehicle off and back on and it was still doing the same thing then it just cut off and wouldn’t start no more. I reached out to Kia cooperate to find out that it’s an extended life time warranty on the engine of the make of my car for rod bearings failure. I contacted Kia of Pelham Al to get an appointment to bring it in I drop it off June 9th , service app was June 10th. They failed to give a rental car … leaving me with no way to work …

On 11/02/2023 I mailed in the KIA request for Reimbursement form. I included a reciept from KIA of Fargo, ND for the Trunk latch assembly. My trunk latch failed in August of 2022, I had to leave Fargo so I cancelled my service appointment. Then purchased the trunk latch assembly and installed it myself. I included labor of $180 and part cost of $62.68. KIA sent an aknowlegment of the reimbursement form on 02/22/2024 they were reviewing the form. As of today I have not yet received the reimbursement. KIA is not following through in a timely manner on this trunk latch recall.

Turbocharger failed at 90000 miles because fan assembly was bad. May have happened when dealership replaced high pressure fuel pump. Fan sheared and metal parts got in the engine about a thousand miles after that.

I was driving on the highway, and my oil pan storage plug fell out of my car. All of the oil leaked out of the engine causing my engine to seize up while I was driving. The dealership says my vehicle is out of warranty, and will not replace it, and that it will cost me $12,000 for a new engine

MY 2017 OPTIMA IS CONSUMING OIL INTO THE PISTONS AND PISTON RINGS WHICH IS SOAKING THE SPARK PLUGS CAUSING ENGINE MISFIRE, MY MECHANIC STATES IT WONT BE LONG TILL THE ENGINE GOES OUT, I TALKED TO KIA AND THEY TOLD ME THE CAR HAS TO BE SEIZED OR KNOCKING FOR THEM TO REPLACE THE ENGINE, KNOWING ITS A PROBLEM.

Ms. Nadine Thomas, who is running for District 44 in Georgia, has served on the Georgia House of Representatives and the Georgia State Senate is my boss and know what I have been through with my vehicle and has heard from KIA in Athens GA that there is nothing they can do. I have a 2017 KIA Optima that I have been having problems with since around 06/2022 or a little before. I have been getting oil changes and putting oil in the vehicle every week or every other week. It finally took a mechanic to tell me it is an issue with Kia's and a recall due to the replacement of the motor because the cars are losing oil. I do not have an oil leak but losing it every week and replacing it and it is expensive for an oil change and a gallon of oil constantly. I have reached out to KIA Manufacturer and case was denied, BBB and KIA denied it all the way, through where I went has far as to the attributor. Georgia Attorney General and they sent a letter to the Bulldog KIA in Athens and they said I have to go through the process of either hearing a thumping noise or motor light flashing constantly and or car shuts off before my motor can be replace. None of this has happened. I had to pay out of pocket for a tune up which was over $300 in Sept 2023 and again early this year 2023 and no reimbursement but it’s on my KIA receipts due to oil consumption (leaking of oil) it’s causing me to keep replacing the spark plugs. Renting vehicles when they would have to keep my vehicle to replace the spark

I am writing to bring a critical safety concern to your attention regarding my 2017 Kia Optima LX. The steering wheel of my vehicle frequently loses power, necessitating a restart of the engine for it to function properly again. This issue occurs randomly, but consistently takes place during steering wheel turns. On one alarming occasion while navigating a winding canyon road, the steering lost power, compelling me to slam on the brakes to prevent the car from falling off the cliff. Another incident occurred while making a right turn, resulting in me slamming on the brakes to avoid colliding with oncoming cars, narrowly escaping a potential rear-end accident. When the steering loses power, it remains functional but demands significant physical effort. Unfortunately, in attempting to steer during one episode, I strained a muscle, leading to a week of suffering. Despite the severity of this safety concern, Kia refuses to address the issue unless they can replicate it during a service visit. The problem occurs randomly, ranging from three times a day to once a month, with no warning signs prior to power loss. Kia has acknowledged this issue, evident in the warranty extension they provided up to 150k miles (attached). Regrettably, when I take the car to the dealership, they decline to address the problem due to an inability to replicate it. I believe this recurring steering malfunction poses a serious risk to my safety and the safety of others on the road. Your intervention in in

The engine code p1326 code popped up after coming to a stop the same code associated with the Kia engine recall but my vin isn’t covered

I drive with my lights on auto. Occasionally the lights go out for no apparent reason. Both inside and headlights. I then have to hold the high beam switch on until I can turn lights on and off or use directional. Sometimes using the directional will cause lights to go out as well. This can happen several days in a row or maybe once or twice a week. I have noticed a few times the box appearing in my dashboard saying lights were off. I had done nothing for them to go out. If a cop sees this happen I am sure to get pulled over. This has been going on for a year=3 trips to 2 different dealers. I brought my car to two different dealers and they both said without it happening when they have it they cannot do anything. I do not understand how a few years ago they fixed something incorrectly and I had to go back for a different part. Apparently this can't be done for this. So, I just risk my life every time I drive at night!!

Every time after I get an oil change I’m constantly having to put oil in it because it goes dry every 2 days and my check engine light stays on before and after oil change, randomly shaking soon as I turn the car on then the oil light comes on every time I go over a speed bump! The car slams on breaks when it wants and has even did it when in fast traffic on the highway.

Got a bsd and check hybrid system while driving.

I was driving at 65MPH on the highway when the warning lights went flashing on my dashboard with "Check Hybrid system", "!HEV", and check engine light. I pulled over to the side of the highway and had a tow truck took it to the dealership to check out. Kia dealership did a diagnostic and mentioned the hybrid engine failed to convert from hybrid to gas and vice-versa. I am at 165,531 miles and Kia is charging me $13,000 to fix it. I am over the warranty of 150,000 miles. The "Check Hybrid system" message has been ongoing since 2021 and Kia mentioned it has to do something with the hybrid battery and Kia no longer makes a replacement battery for the Kia hybrid optima 2017. All Kia does it reset the system for the "Check Hybrid system" message to go away. After a few weeks, the message will appear again on the dashboard. I have upload an image of the dashboard with all of the warning lights. I need help as this is costing to much to fix.

Entered on to the highway and accelerated to get up to speed. Check engine light started blinking and could no longer accelerate.

The contact owns a 2017 Kia Optima. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. Additionally, the engine was consuming an excessive amount of engine oil. The contact stated that the engine was consuming one quart of engine oil every two days after an oil change was performed. The vehicle was taken to AutoZone, where it was diagnosed that the detonation sensor was faulty. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 96,500.

I was driving down the highway and my car just went out in the middle of traffic I almost got into a accident with my kids in the car.there were no warning lights or anything on before it went out I finally pulled over in the far right lane and my car wouldn’t turn back on and started flashing various lights on the dashboard and still wouldn’t turn on I had to call triple A and have the car towed that put me in a very dangerous situation especially with my children in the car

Excessive Oil Consumption: Could cause Engine failure, Engine Seizure due to lack of oil. I have a 2017 Optima with Excessive Oil Consumption issue. I noticed the car is consuming excessive oil, for the third time. Many people had reported this issue, leaving customers with expensive repairs. This issue could cause Engine failure, Engine Seizure due to lack of oil. I took the vehicle to the dealer, (Kia) recommended additional services and kept the vehicle overnight for testing. These additional services were outside the normal maintenance interval and are expensive. Quick History: -As of 12/26/2023 Vehicle was dropped off due to excessive oil consumption, this time before the service interval was due. -2017 Optima/ 83,200 Mi -All Oil changes and scheduled maintenance performance at normal interval, sometimes sooner due to the Excessive oil consumption. -Car is for personal use/ normal driving - No Leaks detected in the Car

I have my headlights on auto so they turn on but they turn on during the day and then off at night they turn on they have turn off when I'm diving at night on freeway and turn back on

This has happened several times to me! While driving the steering wheel locks up and I have to coast to a stop to turn off the engine to reset the wheel. It has happened going 60mph down the hwy with my 3 young kids in the backseat. Going 30mph and I have almost hit two cars because of this. If I couldn't stop in time and time hwy wasn't a straight road we would've died. The part I need for the car has been on a back order for over a year. Kia said its not that big of an issue but my life and my kids life is at risk every day!!! Please help!!! This can't only be happening to my car!!!

The contact owns a 2017 Kia Optima. The contact stated while driving approximately 35 MPH, the check engine warning light illuminated. The contact reset the check engine warning light however, the light became illuminated again. The vehicle was taken to a dealer and the contact was informed that the engine oil was low and needed to be topped off. Additionally, the dealer offered to perform an oil consumption test. The vehicle was not repaired. The contact stated that he had researched online and related the failure to an engine design flaw. The contact requested that the dealer attempt to repair the engine and was refused. The contact was advised by the dealer to drive the vehicle until the engine failed and then he would be placed under consideration for a manufacturer engine replacement program. The manufacturer had been informed of the failure. The failure mileage was approximately 76,000.

Driving down the interstate, the vehicle started to decelerate and the engine light started flashing. Got it to a mechanic and he started that it was a knock sensor failure P1326 code. Same as the recalls, but my vin number was not included in the recall report. Already had this vehicle in for excessive oil consumption. Paid for the dealer consumption test. They said it only burned a qt. and that was acceptable. In 1000 miles. Have done my own 1000 mile test and have been burning 1.5 or more qts. on three separate tests. Something has to be done about these engines. This is dangerous when going interstate speed and dropping to 20 mph in heavy traffic.

Oil from engine does not cycle through the engine and instead it foams up and comes out of the top of the engine and I need to put oil in my car every week.

The contact owns a 2017 Kia Optima. The contact received notification of NHTSA Campaign Number: 23V594000 (Latches/Locks/Linkages) however, the part to do the recall repair was not yet available. The local dealer was contacted and determined that the next available appointment would be in February 2024. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue and confirmed that there were a lot of customers in front of him and the dealer would not be able to get to the vehicle until February 2024. The contact stated that the vehicle was consuming an excessive amount of engine oil and failed to start occasionally. The vehicle was not diagnosed or repaired. The failure mileage was approximately 126,000. Parts distribution disconnect

The contact owns a 2017 Kia Optima. The contact stated that while driving at 60 MPH, the vehicle inadvertently decelerated and then lost motive power. The check engine warning light was illuminated. The contact was able to restart the vehicle and drove to the residence. The contact stated that the vehicle jerked while driving. An independent mechanic diagnosed the vehicle at the residence and retrieved DTC Code: P1326, and the contact was informed that the engine needed to be replaced. The vehicle was not repaired.

The engine on this vehicle caught fire while the vehicle was parked and not running. It had previsouly been drive for approximately 4 hours throughout the day but at the time of the incident there were no warning dashlights present. It is currently available for inspection, however depending on the length of this invesitagion it may no longer be available as i work with my insurance company determing next steps. My safety and the safety of other were put at risk by and open flame and smoke that occured during the fire. Ultimately the Fire Department were required to put out the fire. Approximately 8 months ago the engine was replace by the dealership Summit Place Kia East in Michigan due to an open recall for a knock sensor issue. I suspect this vehicle will be a total loss.

I was driving my kiaon a very busy interstate. When I was going around 65miles per hour and all of a sudden I lost all power it went from 65 miles per hour to 30 all at once when I hit the gas peddle the car went in jerks finally I got it back up to 55 but it only goes in a jerking motion and r.
