Risk. If the VPD activates while the vehicle is being operated in Electric Vehicle (EV) mode, there may be a loss of power, increasing the risk of a crash.

Remedy. Kia will notify owners, and dealers will remove the VPD switch and install two newly designed Battery Management Systems (BMS) that contain Overvoltage Protection Devices (OPDs), free of charge. The recall is expected to begin May 2018. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC162.

3 weeks ago I had my vehicle towed to Car Pros Kia in the city of [XXX]. They said that there was an issue with the engine which should be covered under the extended lifetime warranty that KIA issued Me 2 years ago due to a recall and a system update that they required that I do on my vehicle. We did the update. We are having the same mechanical issues we did two years ago with the first recall. I reached out to Kia corporate Kia says they're reaching out to Car Pros Kia I've been in contact with both companies three to four times a week for the last 3 weeks and they both are saying they never received anything from each other. The mechanical issue is very dangerous the car jerks slows down to a very low speed around 30 Mi an hour in the middle of high speed traffic. Is very dangerous I've been without a vehicle for 3 weeks which is slowing down my process to continue to pay my bills I need my vehicle can I get any help from anyone. I feel disrespected taking advantage of and now I'm starting to fall into a financial issue because they cannot communicate with each other to fix an issue that should be covered under the warranty that they said it would and I have documents to prove it INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2017 Kia Optima. The contact stated that after receiving an oil change, the contact became aware that the engine oil level was low. The vehicle was taken back to the service center, and the engine oil was topped off with an additional quart of engine oil. The contact was advised to return for an oil consumption test. There was no oil leak found and the contact was informed that there was an internal oil leak.

While driving at highway speed, my engine began to produce a loud knocking noise without prior warning. Within few seconds, the engine seized completely causing sudden loss of motive power.This caused a dangerous situation— loss of power steering and barking at highway speed, leaving me stranded in traffic lanes. I was forced to coast to the shoulder. The vehicle was towed to the nearest independent repair shop because it was not drivable and I was stranded far from home. The shop diagnosis —- seized engine due to big end connecting rod bearing seizure, identical to NHTSA Recall 17V-224 and KIA recall SC 17/ SC165 and TSB P1803 related to Theta engine bearing wear and engine seizure.My vehicle has the 2.4 L engine covered by this recall/defect.The failure occurred exactly as described in the recall: knocking , the seizure. KIA has denied warranty coverage because the vehicle was initially diagnosed and repaired at independent shop after the roadside emergency.The shop was used only because the vehicle was immobilized on the freeway away from home. I did attempt to contact a dealership in FortWorth, Texas, Morits KIA, but they could not provide roadside assistance or a tow solution at that time. I am reporting because: 1) This is a sudden loss of power at highway speed, which is a major safety risk 2) This appears to be the same defect KIA has recalled for, but the vehicle was not remedied or remedy failed 3) KIA is refusing to honor the extended warranty for this known defect

I am requesting urgent assistance regarding my 2017 Kia Optima EX, which is experiencing a serious oil consumption/burning issue. The vehicle is burning oil into the engine, causing the oil level to continually decrease and creating a significant concern for engine failure, overheating, or a potential vehicle fire. I am extremely concerned about my safety and the safety of others because I depend on this vehicle every day. This is also my only vehicle, and I am still making payments on the financing. I do not have the financial ability to simply purchase another vehicle or take on a new car payment. I am asking Kia to please take this matter seriously and investigate the vehicle as soon as possible. I am requesting that Kia review whether there is a known engine issue, applicable warranty or assistance, recall/campaign coverage, or any other program that could help with the necessary repairs or engine replacement. I cannot afford to lose my only means of transportation because of an engine problem that is beyond my ability to financially resolve. I am asking Kia to work with me toward a safe and reasonable solution as urgently as possible.

Since 4/1 my car has intermittently lost power steering. I received dashboard warning lights and the wheel was difficult to turn. When I shutoff the car and turned back on, the warning lights were gone and the steering returned. My mechanic did a diagnostic and found the following codes c1259, c1260, c1290 and c1688 each time the incident occurred. After research, we discovered these codes relate to TBS CHA114 and TSB CHA864 under extended warranty WTY023. I was unable to upload the TBS documents. The same thing happened on 6/18. I brought the car to a different dealer. The first time they supposedly did a diagnostic and said there were no codes. I have pictures of the codes. They said it did not matter because the codes need to be active and the lights need to be on the dashboard. The second time at a different dealer, they didn't do a diagnostic but said it did not matter because the codes need to be active. No where is any documentation does it say the codes need to be active. They are stored in history and Freeze frame data. It is impossible for me to get the car there with the illuminated dash and "active" codes because when it happens, I cannot steer the car and when I shut if off they go away. Plus when I get to the dealer, they will tell me they cannot take me and to make an appointment. I am now working with KIA escalation department but she informed me today that she did not have the authority to authorize a dealer to repair the car. When I asked who does she said I

The engine of this vehicle is still exhibiting the issues that are under the class action lawsuit. Engine. Was not repaired properly by dealership. I must change my oil around 1700 miles

The contact owns a 2017 Kia Optima. The contact stated that on three of four occasions while driving at approximately 50 MPH, the vehicle began rattling and shaking, and he observed a knocking noise emanating from the engine compartment. The check engine warning light illuminated. The vehicle was taken to a dealer where it was diagnosed that the knock sensor needed to be replaced, and he was advised that his vehicle may have been included in Manufacturer Recall Number: SC162. The vehicle was not repaired. The manufacturer was notified of the failure and a complaint was filed. The failure mileage was approximately 98,000.

Constant Mis-firing, must put oil in car every 3 to 4 weeks. Hesitation when driving and sputtering.

The electrical wiring harness connecting to the hybrid system electric fuel pump(s) was found to have significant corrosion and a missing factory-installed protective covering. This is a manufacturing defect. The protective covering was never installed at the factory, leaving the wiring exposed to moisture and corrosion from the time the vehicle was built. COMPONENT THAT FAILED: Electrical wiring harness to hybrid electric fuel pump(s). Missing factory protective covering caused corrosion. The failed component is available for inspection upon request. SAFETY RISK: Corroded wiring in a hybrid vehicle electrical system poses serious risks including electrical shorts, potential fire hazard, and sudden loss of hybrid propulsion while driving. The vehicle is currently inoperable and unsafe to operate. CONFIRMED BY DEALER: Yes. The vehicle was taken to an authorized Kia dealership where it remained for approximately 8 months. The dealership and manufacturer inspected the vehicle and confirmed the wiring issue but denied warranty coverage. THIRD-PARTY CONFIRMATION: A third-party warranty representative independently reviewed photographic evidence and confirmed the missing protective covering is a manufacturing defect, not wear-and-tear or owner-caused damage. MANUFACTURER RESPONSE: The manufacturer denied warranty repair, falsely claiming the hybrid component warranty does not transfer to subsequent owners. Federal warranty law requires transfer unless explicitly excluded in the war

On March 23, 2026, I took my 2017 Kia Optima Plug-In Hybrid (VIN: [XXX] ) to Mark Kia [XXX] ) solely for two open safety recalls: SC218 (Engine Inspection/Replacement and KSDS software installation) and SC278 (Emergency Trunk Latch Release) under Repair Order #6807251. No customer-pay work was performed. The Multi-Point Inspection that day noted only the cabin air filter. During the drive home on March 23, a faint rotten-egg (H₂S) smell appeared for the first time. By the morning of March 24, 2026, the smell was severe. I immediately returned the vehicle. Under new Repair Order #6807360, a second Multi-Point Inspection suddenly recommended $1,134.10 in customer-pay services (new 12V battery, fuel induction service, cooling system service, brake fluid exchange, and ATF exchange) that were not flagged the previous day. Since the recall service, the vehicle has developed numerous new defects that never existed before: Rotten-egg smell (H₂S) Intermittent AC that blows warm in stop-and-go traffic Passenger-rear power window clicks but will not roll down Brake warning (“Stop vehicle and check brakes”) “Key not detected” message Passenger-side mirror pushed in with temporary motor malfunction 12V battery cover left completely disassembled and misplaced in the trunk Complete no-start / dead 12V battery condition (will not crank even after multiple jump attempts as of March 30, 2026) On March 24, 2026, I sent a formal demand letter by certified mail (received and signed for by the dea

Engine issues started the third month after sales. Jerking, shaking, declining performance, metal clicking noise, loss of power while driving. Kia has been working on the car for a year.

The contact owns a 2017 Kia Optima. The contact stated that while driving at 67 MPH, the vehicle experienced a loss of drive power, and the vehicle went into LIMP Mode. The check engine and HEV warning lights were intermittently illuminated. The contact entered the vehicle settings, and the ECU message was displayed. The contact stated that the failure had occurred three times. The vehicle was taken to the dealer, but the failure could not be duplicated. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 130,000.

“My vehicle, a 2017 Kia Optima, had repeated safety issues documented in service records. Despite multiple repair attempts (per attached records), the problem remained unresolved and put my safety at risk. I’m seeking further investigation or resolution.”

My fiancée and I just recently bought this car with the 1.6T-GDi engine I immediately replaced the oil even though the dealership said that he just replaced it. I put 7 quarts of oil topping off from awk consumption after I initially changed the oil filter. Those 7 quarts were added over the period of three weeks and it’s just progressively gotten worse. I’m putting a quart to 1.5 quarts of oil in here every other day. Worried about it causing total failure & being at risk of being stranded with 2 kids due to the only engine I’ve been able to find that Kia doesn’t have any recall touched base on is the GAMMA 1.6 engine. The turbo GAMMA 1.6. The N/a 1.6 was covered but it has ungodly pop/clunking backfiring sound coming from either intake manifold or valve train please help. Times are hard enough as it is to be without a vehicle due to a fault other than none of my own the dealership extended powertrain warranty isn’t being honored by Kia even though they said it would just don’t want something to happen to me or the car that’s beyond my capabilities and knowledge and ultimately result in my spouse not having a reliable and/or safe means of transportation to/from work and commuting kids as well. Thanks in advance

Unknown

The vehicle is consuming excessive amounts of oil. The dipstick was completely dry before 5000 miles were up. I had to add some oil to the engine to avoid engine failure. I have reported this to Jim Ellis dealership in Kennesaw GA but I was told to drive the vehicle until it knocks or the knock sensor goes.

The engine in my 2017 Kia Optima (VIN: [XXX] ) seized and locked up, a known defect associated with Kia’s Theta II 2.4L GDI engines. When I contacted Kia regarding engine replacement, I was told coverage would not apply because a required KSDS ECU update recall was not completed. During multiple phone calls with Kia Customer Care, Kia admitted that they did not have my contact information on file and added it during my call. Because Kia did not have my information, I never received any recall notification and was denied the opportunity to comply with the KSDS update. Kia has also provided conflicting information regarding whether recalls were open on my VIN while still relying on recall completion status to deny coverage. I believe Kia failed to properly notify me of a safety recall and is unfairly denying coverage for a known engine defect.

Kia Engine Settlement-Kia America and Grand Forks KIA dealership is refusing a mandatory diagnostic test for excessive oil consumption under the Kia Theta II Engine Class Settlement, despite the vehicle having the required KSDS software update installed. The vehicle is consuming 1 quart of oil every 1000 miles, requiring constant topping off to prevent engine seizure. Vehicle was brought to Kia Grand Forks on 7/21/25 was told that the valve gasket needed to be changed. Engine light illuminated 10/2025 and car was unable to make it back to dealership from 58369. Vehicle was brought to local mechanic where I was told that the has failed and that the spark plugs had oil on them. Mechanic changed the spark plugs to make it to Grand Forks Kia on 10/14/25 I was told that the Turbo needed to be replaced for $3300 before they can do an oil consumption test. There were no issues with the turbo before it was driven to Grand Forks on 10/14/25. Kia America refuses to cover the engine warranty which will lead to "sudden engine stall, loss of power, or vehicle fire," which are primary safety concerns monitored by NHTSA.

The contact called on behalf of her daughter who owns a 2017 Kia Optima. The contact stated while driving at approximately 60 MPH, the vehicle made an abnormal knocking sound, the cruise control was inoperative, the infotainment screen darkened, and the charging outlet was inoperative. The Check Engine warning light was intermittently illuminated. The vehicle was taken to the contact's residence, and the contact used a vehicle scanner to scan the vehicle. The contact stated that DTC: P1326 for the Knock Sensor Detection System (KSDS) was found, which detected excessive engine vibration. A dealer was contacted; however, the vehicle was not diagnosed or repaired by the dealer. No further information was available. The failure mileage was approximately 98,000.

Vehicle experiences sudden and dangerous loss of power while driving, including hesitation during acceleration, consistent with connecting-rod bearing failure risk known in this model’s GDI engine. Dealer estimate found timing and oil-flow component failures connected to internal engine damage. Vehicle is unsafe to drive and stalls/lacks power unexpectedly, creating a high risk of crash.”

I own a 2017 Kia Optima with a major internal engine defect. Starting shortly after purchase, the car lost power and consumed fuel unusually quickly. Over time, the engine began burning excessive oil and now produces a loud knocking sound (bearing knock), indicating internal bearing failure. These symptoms are consistent with known Kia engine defects (bearing wear / piston ring failure). The defect is a serious safety concern: because of weak bearings and high oil consumption, the engine could stall, seize, or catch fire. The dealership has refused to repair or replace the engine. I am reporting this as a safety defect and request NHTSA investigation.

The contact owns a 2017 Kia Optima. The contact stated that upon routine maintenance with a local independent mechanic, it was discovered that the vehicle had low engine oil. No warning light was illuminated. The vehicle was taken to a local dealer, where it was determined that an oil consumption test was needed to determine any failure. The vehicle was not repaired. The check engine warning light was illuminated. The contact stated that engine oil was added almost every 2 weeks. The message to "Contact the Dealer" was displayed. The vehicle was towed to Team Kia of El Cajon (541 N Johnson Ave, El Cajon, CA 92020), where it was determined that there was engine oil leaking onto the catalytic converter. The contact related the failure to a Kia recall related to a connecting rod bearing failure. The manufacturer was made aware of the failure. The failure mileage was approximately 100,400.

I purchased the 2017 Optima Hybrid from Huntington Beach Hyundai on [XXX]. I made sure to double check with the dealer if the engine and hybrid battery were in good condition, in which the salesman reassured me everything is good. The car was driving okay for a while, and I had oil change and tires/alignment changed recently. Just barely 4 months in after I owned the car, the incident happened on the night of [XXX]. I was driving on the highway near the Getty going roughly 70 mph up the mountain roads while all of a sudden the "check hybrid system" warning came on in the car. The car immediately went into limp mode, and I did everything I could to slow the car to a complete stop, and stop on the freeway shoulder safely. It was a traumatizing experience to me, as this is a major safety issue with the vehicle, and other cars were travelling really fast in LA mountain areas. I had the car towed to a auto repair shop the next day, the mechanics did a deep inspection and informed me the hybrid inverter has failed. I paid $2,177 to replace the hybrid inverter with the mechanic. The mechanic also informed me while they were test driving they heard a knocking sound from the engine. I did a look up and found out there is a class settlement and safety campaigns on the engine for 2017 Optima Hybrid due to the faulty factory rod bearings, and the 150K miles extended warranty from Kia should apply to replace my faulty engine free of charge. I will be getting my car towed to Car Pros Kia i

Engine is consuming a large amount of oil. Oil is gunking up spark plugs causing them to be replaced every 10-12 months. Have to add oil 3-5 times per month. This is our 2nd Kia optima and the first (2011) with seized engine in which Kia paid for replacement.

Oil is burning too fast... Car has had an issue like this in the past and the problem resulted in a blown engine... Re-call was found by dealer and honored and endinge re-placed.. Car is now expierenceing this problem again... Second, steering wheel is locking when turnning fully left... Third, car smells extremely strong like gasoline when car is warming up...

Engine completely shut down when driving it. Had it replaced among many other things then found out it was part of a class action lawsuit. I have spent two years trying to recoup the money I lost in repairs and the cash I paid for the car.

I own a 2017 Kia Optima. My vehicle was brought in for the tail light recall at Lupient Kia, but the dealership only replaced a bulb and refused to replace the harnesses. I was told by the service advisor (Brad Baranowski) that my tail lights had “nothing to do with the recall” and that I would need to pay $210 for a diagnosis, even though I am still experiencing the exact defect described in the recall (shortage/failure in the harness causing tail light malfunction and warning lights). This incomplete recall repair is a safety hazard my tail lights continue to fail, and I have received tickets because of it. I request that NHTSA investigate Kia’s failure to properly complete this recall. Lupient Kia 6030 N Green Bay Ave Glendale, WI 53209 Phone: (414) 351-3000

For the past year, I have been constantly replacing the spark plugs and ignition coil in my 2017 Kia optima. Recently I have had the valve cover gasket replaced. It is a constant oil consumption issue. I have received the P1326 diagnostic code. My dealership told me that the engine cannot be replaced unless it’s knocking. This is my only mode of transportation, and I would hate for me to be stranded because I’m waiting for the engine to knock for my engine to be replaced.

Car began hesitating and stalling, particularly from a stop. Engine light came on. Took the car to the KIA dealership for diagnosis. Was told by svc coordinator that the diagnosis indicated a bad knock sensor. The technician replaced the knock sensor, then test drove the car. It failed immediately. I was told that it would likely need engine replacement. After a few days, svc coordinator called and said that KIA recommended replacing the knock sensor (again) and perform a tuneup. They declined to replace the engine. The car runs in "limp home mode" (Kia's terminology), hesitates and stalls so as to make it very unsafe to operate. The engine on this car was replaced about two years ago for excessive oil consumption. There cannot be more than 30k miles on the new engine. KIA stated that there is a lifetime warranty on the replaced engines, but are apparently not going to honor the warranty. Car is serviced regularly and is in otherwise excellent condition.

My car is burning oil and oil is covering my spark plugs. Was mentioned about decarbonizing

The contact owns a 2017 Kia Optima. The contact stated she had noticed that the vehicle required more oil between oil changes. Additionally, the contact had noticed that oil was leaking underneath the vehicle. The contact stated that the low oil pressure warning light would only illuminate upon depressing the brake pedal. The vehicle was taken to an independent mechanic, where no oil leak was found, and the contact was advised to constantly check the engine oil level. The contact stated that upon checking the oil level recently, five quarts of oil needed to be added to the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 133,000.

--- **Summary of Complaint – 2017 Kia Optima** My 2017 Kia Optima (VIN: [XXX] ) experienced sudden engine failure due to a damaged piston. There were no warning signs—no knock codes or dashboard alerts—prior to the malfunction. Despite regular maintenance and timely oil changes, Kia denied warranty coverage, leaving me with significant repair costs. This issue appears consistent with reported engine problems in similar Kia models and could represent a broader manufacturing defect. I'm submitting this report in hopes of prompting an investigation into a potential safety hazard. A recall may be necessary to prevent similar failures and protect INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving my 2017 Kia Optima (Theta II engine) at approximately 115,900 miles, I suddenly experienced engine failure. The vehicle began to stall and produced a burning smell shortly before the engine seized completely. I had the car towed to a Kia dealership, which confirmed an internal engine failure and noted that there were no signs of external oil leaks or neglect. The failure occurred only 4,500 miles after my last oil change, which was documented and professionally completed. The Kia technician mentioned verbally that this was due to excessive oil consumption and burning — an issue I later found to be widely reported in other Kia vehicles using this engine type. The estimated repair cost is over $14,000, which is more than the value of the vehicle. Despite my warranty being expired, this type of failure appears consistent with known manufacturing defects. I am reporting this for public safety and accountability. The vehicle failed without warning and could have caused a dangerous situation on the road.

Excessive oil consumption started at 61,000 miles, causing engine misfires and dangerous power loss on the road. Engine codes 1326 and P0304 were frequent. Despite numerous services, including sensor replacements, spark plugs and oil top-offs, the problem worsened. At 97,769 miles, the dealer said a full engine replacement is needed along with other pertinent repairs related to the engine are needed. The situation was life-threatening each time as they occurred while driving and I now no working vehicle after my husband's recent death. Kia dealerships acknowledged the defect but refused to replace the engine and advised that Kia Corporate was refusing, although no claim information was ever provided that they indeed contacted the corporate office. I am seeking NHTSA support in holding Kia accountable.

Code P1326, Faulty Knock sensor on 2.4GDI

The car stalled out

I previously submitted a report regarding engine failure in my Kia 2017, Optima. I’d like to update the complaint with new details. Upon mechanical inspection, it was confirmed that the engine bears Hyundai branding and has sustained internal damage including broken pistons and valve failure. These issues appear consistent with the known oil ring defect affecting Hyundai-manufactured engines used in Kia vehicles. Symptoms included: Engine knocking and rough idling Sudden loss of oil and reduced performance Full engine failure requiring replacement I believe my vehicle may have been missed in the recall or settlement programs and request this update be added to my case. I’m willing to provide repair estimates, diagnostic reports, and photos upon request. Thank you for investigating this issue further

My Kia optima fe 2017 has been consuming a lot of motor oil it takes a quart every 2 to 3 weeks and of if I drive it more than average it needs motor oil sooner

Engine is failing and using over 3 quarts of oil every 700-100 miles. Spark Plugs have become oil fouled and replaced all 4 spark plugs June 11th, 2024 and replaced all 4 spark plugs again January 12th, 2025. Today July 7th, 2025 Check Engine light came back on with Engine Misfire code P0303 Cylinder 3 Misfire, changing spark plugs again today. My safety is put at risk because oil consumption is a know issue with Kia GDI Engines. At any moment my car can run out of oil if it is not check every other week causing my engine to completely fail or a spark plug become Oil fouled and a spark plug needing to be replaced. In July of 2024 when this happened I was on the highway going 70 mph and my car just completed shut down. I could have been seriously injured had I not been able to pull over and only been 5 miles away from my home. I called Kia today to start an Oil Consumption test, stated I am the 2nd owner and while this is a known issue I will pay for and Upper Engine Clean which is only a band aid. This problem has been confirmed with Kia that the GDI Engines are consuming oil. I have also replaced all Engine Coolant, Coolant Temperature Senor, Thermostat as well as the PCV Valve.

Warning lights displayed for ABS and ESC systems. Had Autozone pull the OBD2 codes which indicated the left rear wheel speed sensor failed resulting in failed/disabled ABS and ESC systems. I replaced the bad rear wheel hub/sensor which corrected the problem. I no longer have that failed component. A few months later, warning lights came on again. I again had the codes pulled by Autozone and this time it was the right rear wheel speed sensor. I have the new part but have not yet replaced it so I could keep the defective part for the right wheel. The first one failed in April 2024 and the second in November 2024. This seems to be a bad design with two of the same parts failing in the same timeframe affecting two main safety features of the vehicle

The contact owns a 2017 Kia Optima. The contact stated that the low battery warning light was illuminated, and the message stating an electrical failure was occurring was displayed on the infotainment center. The battery was tested and found to be non-defective. The vehicle was taken to AutoZone, where a mechanic diagnosed and determined that the alternator had failed. The vehicle was not repaired. The contact found information of NHTSA Campaign Number: 18V161000 (Hybrid Propulsion System) and linked the recall to the failure. The dealer was contacted and informed of the failure. The dealer confirmed that the VIN was not included in the recall. The manufacturer was not informed of the failure. The failure mileage was approximately 120,000.

My vehicle is experiencing engine issues consistent with the known Theta II GDI engine defects — including rod bearing failure piston rings engine stalling, I understand that Kia has offered extended warranty coverage through the engine defect settlement, provided the Knock Sensor Detection System (KSDS) update was installed before failure. I am unsure whether this update has been applied and would like to confirm my eligibility. I respectfully request: 1.Confirmation of KSDS update installation on my VIN 2.A review of my eligibility for engine inspection and coverage under the extended warranty 3.Assistance with coordinating service and coverage at my local dealership (LeBlanc Kia, New Iberia, LA) I am the second owner of this vehicle and want to ensure I am treated fairly under the known warranty extension guidelines. Thank you for your support. I look forward to your prompt response.

For years there has been a problem with my vehicle after it rains. On the drivers side when turning the steering wheel there is a scraping noise. The dealership service always said they can’t hear anything or duplicate the problem. Now the issue has extended to the passenger side. After a heavy rain or going through the car wash water get in under the glovebox. My sunroof is fine and not clogged, the problem is something else. Water no matter the source should not be getting inside the car causing odor issues, interfering with the operation of turning / steering gears. This needs to be a recall to force Kia to acknowledge this well known problem from hundreds of online complaints regarding leaks.

I purchased a 2017 Kia Optima from Deal Makers Auto Sales in Georgia in February 2024. The vehicle broke down within 3 months. I later found out it had four open safety recalls that were never disclosed at the time of sale. This is dangerous and deceptive, and the dealership refused to take responsibility or make repairs.

Engine stalled out while driving lyft. Got passenger to their destination safely, however lyft is my only source of income big risk to stall out on a highway.

Randomly when turning, my steering will jolt in the opposite direction and lose power steering. The red power steering light does come on at this moment where I have to pull over, turn the car off, and restart and the symptoms clear itself up. In addition, there is there is, randomly, grinding noises (and I can feel it in the steering) when turning. When this occurs, relocating the steering column by changing the position (via tilt and telescopic) seems to help clear it up for awhile. I have almost jolted to oncoming traffic when turning and a few instances. I have had it serviced to check steering points at tires, axel, cv joints, and my mechanics can't seem to find the fault there. Even after doing alignments, it helped for a little bit but the same problems came back. They believe it to be a steering column issue. They believe that it is getting caught when turning and causing the issues. This has been occurring for about 6-8 months now. The power steering losing power happens maybe once or twice a week to once every two weeks. The grinding and vibration in the steering column while turning happens a few times a week to maybe just once a week. Its occurrence worsens when it rains. I am reporting this because I have read other reports of people have the same experience as myself.

The power steering stopped working and the car became hard to turn because of it. The power steering light (red color with steering wheel and exclamation point to the right of it) came on also.
