ENGINE

The component that failed was the engine of my Kia vehicle. The vehicle was purchased in 2020. In Q4 2022, I received a recall notice by mail regarding the engine. I immediately took the vehicle to Kia of McKinney, TX, and requested that the recall repair be performed. I was informed at that time that the engine could not be replaced until it actually failed. This forced me to continue driving a defective vehicle for several years. The engine ultimately failed in the second week of June 2025, when the car would not start. It was towed to Southwest Kia in Texas, where it remains available for inspection. My safety and the safety of others were put at risk because I was instructed to continue driving a vehicle with a known defective engine. Kia’s refusal to remedy the recall in advance increased the risk of sudden stalling, engine seizure, or loss of power while driving — all of which pose serious hazards on the roadway. The problem has been confirmed by Kia’s own service centers. Southwest Kia acknowledged the engine failure but denied coverage, citing a supposed “gap” in maintenance records. However, Kia never informed me that there were specific maintenance requirements tied to recall eligibility, and I was never given a clear diagnosis of if the failure aligned with that of the recall. Kia corporate has denied responsibility for replacing the engine despite the active recall. There were no warning lamps or messages prior to the engine failure. The car simply failed to start in June 2025. At no earlier point was I warned that the vehicle was unsafe to drive, nor was I given any proactive remedy other than waiting for failure. I am requesting that Kia be compelled to honor the recall and replace the engine, as their refusal has left me with a significant financial loss and ongoing safety concerns.

ELECTRICAL SYSTEM

I have repeatedly been denied service by KIA Customer Service and KIA Dealerships regarding my safety recall. This ongoing issue has caused significant stress and inconvenience. I am simply requesting that my recall be completed so I can safely operate my vehicle. Despite my efforts, I continue to receive invoices for repairs while being denied the necessary service. I am frustrated by the lack of support and resolution.

ENGINE

The vehicle unexpectedly stalled while idling at a complete stop, posing a serious safety concern. Shortly afterward, the check engine light illuminated. These events occurred around 78,000 miles. Prior to the stall, the engine had been making occasional knocking or tapping noises, particularly at idle. The vehicle was immediately taken to a certified Kia dealership, where a technician diagnosed the issue as engine failure consistent with a known manufacturer recall affecting this vehicle model and year. A recall claim was submitted to the manufacturer, but the repair has been delayed for over a month with no authorization to proceed. No loaner vehicle has been provided. The engine failure puts the driver and others at risk, especially if the vehicle were to stall during active traffic conditions. The problem has been confirmed by the dealership but has not yet been resolved by the manufacturer. Inspection by the manufacturer is still pending. Warning symptoms included the engine light and knocking sounds, which began shortly before the stall occurred.

ENGINE

My 2015 Kia Optima (VIN [XXX] ) case # [XXX] is covered under Kia’s engine recall for potential engine failure/fire. However, Kia and Ray Skillman Northeast Kia, Indianapolis refused to perform the recall repair because I do not have the last two years of oil change records. This is a safety recall, not a warranty claim, and denial of repair violates recall obligations. I am requesting NHTSA’s assistance to ensure Kia complies with the law and replaces the defective engine. Thank you.

Well my paint is peeling everywhere I only had car 4 years, I can barely wash it because the car wash takes more paint off, I seen Hyundai do a paint recall or something like that so I'm wondering if it's the same for Kia.

STRUCTURE:BODY

The car is a 2015 model and as shown in the pictures, the paint on the tail is damaged. This is a defect of the manufacturer.

ENGINE

Purchased 2015 Kia optima LX 4 cylinder. Had the car for 7 months. Driving home car stalled driving into our driveway. When restarted the engine there was a loud noise tapping. Oil light came on. Checked oil it was on empty. No oil light has come on ever before the car stalled. Regular oil changes . Researched the over 900 complaints. Same thing that has happened to everyone else. Thankfully this didn't happen on the drive home in traffic.

Driving towards town on freeway car suddenly die at high rate of speed and lost power at the wheel had to sway to side of road opened up hood of the car and smoke came out had recker pick me up and drove it to the house and started to find the issue and the starter module burn up . the gas line was near started . replace starter and now the car doesn’t crank so is used wrench to trunk motor and now more seized up remove spark plugs and tried manually turn motor nothing lookup recalls on the matter and it said it was recall on the main bearing of the car are premature and Kia won’t honor the recall due to no oil change records I have all items bought and tow truck expense

ENGINE

While driving, the engine suddenly shut off without warning. The car coasted to a stop and would not restart. When attempting to start it again, the starter smoked, and the engine would not crank or turn over. This is a serious safety hazard as the engine failure occurred with no warning and matches the symptoms of the known Kia Theta II engine recall for bearing and seizure issues. My VIN is not currently listed as part of the recall, but it experienced the exact same failure. I am requesting that NHTSA investigate and pressure Kia to include my VIN in the recall campaign, as this is a sudden engine seizure defect that could cause a crash if it happens at speed.

ENGINE

The contact owns a 2015 Kia Optima. The contact stated while the contact's wife was driving at an undisclosed speed, the vehicle made an abnormal ticking sound. There was no warning light illuminated. The vehicle was taken to an independent mechanic, where the contact was informed that the failure could be related to the engine. The vehicle was then taken to the dealer, where it was diagnosed that the engine had failed. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The contact was informed that the VIN was included in an unknown related engine recall; however, the engine repair or replacement was not covered under warranty due to missing service documents. The failure mileage was approximately 78,000.

ENGINE

While driving my 2015 Kia Optima, the engine suddenly failed without warning. I noticed a loss of power, and shortly after, the oil pressure warning light illuminated. Upon pulling over safely, I discovered that the engine had drained all of its oil, despite recent maintenance. There were no prior warning signs or leaks visible. This posed a serious safety risk as the failure occurred in the midst of traffic. The vehicle had approximately 75,885 miles at the time. A mechanic later confirmed catastrophic engine failure due to oil starvation. This issue appears to be consistent with known engine defects in similar Kia models.

ENGINE

The engine seized and is out of commission on 7/16/25.

The paint on my 2015 Kia Optima is severely peeling off, especially on the trunk, hood, and driver-side pillar. The passenger side also has some peeling. This is not a minor cosmetic issue — it significantly affects the vehicle’s appearance and long-term durability. Many other owners of this model have reported the same issue, indicating a widespread paint defect. I contacted Kia through several official channels and received no response. I believe this is a manufacturer defect and should be addressed as a broader consumer issue.

ENGINE

I own a 2015 Kia Optima (VIN:[XXX]) with a 2.4L GDI engine. The engine has failed — a local repair shop diagnosed it as a “jumped timing” issue, which matches the well-documented Theta II engine defect. I never received recall notice or notice of the required KSDS update. Kia has denied me coverage, stating the update was not done before failure. I now have a vehicle that is undriveable and potentially unsafe. Kia confirmed there is no extended warranty or coverage for rod bearing failure — despite widespread issues — and they ignored my open fire-risk recall (NHTSA 21V331000) in their denial. I am requesting that NHTSA review why my VIN is excluded despite the same failure symptoms, and ask that Kia be required to expand recall eligibility or offer a goodwill resolution.

Car was purchased April 2025, I’ve had it less then 2 months and check engine light came on and then flashing. I had it scanned at Auto Zone and was told the code is VVT Solenoid. I had it replaced 6/12/25. I was told by the mechanic that it didn’t solve the issue and metal shavings were on the old one. The car is still constantly going in to limp mode and there’s a knocking noise now. The Auto zone scan listed the mileage as 150,000 yet the car dealership listed and sold it as 101,000. I have a 2015 Kia Optima Ex. The title does not list it as a rebuilt and appeared to be fairly clean and maintained . The mechanic told me the engine needs replaced.

As I was driving going at a rate of 40 MPH my engine shut off. I was able to pull to the side of the road without an accident thankfully. Cranked the vehicle back up and then the same thing it happened again. No check engine light came on either time. Drove for another 200 miles no issues. Going apx. 75 MPH it went into limp mode and check engine light came on and the P1326 code appeared. There is a recall on this vehicle for this code. However the dealership states it’s a knock sensor needing to be replaced and I will have to cover that. The same knock sensor they had me update in 2018 under there advisory. The motor burns apx. 2 quarts of oil every 3000 miles. Requires oil to be added to maintain oil level in between oil changes. Irregular mechanical noise (rattle) during cold start ups. I am scared to drive this vehicle and do not feel I am being treated fairly due to the recalls on this engine.

I purchased a 2015 Kia Optima 2.4L GDI (VIN: [XXX] ) with a blown engine, which is covered under Kia’s extended engine warranty. I contacted Jim Butler Kia in Chesterfield, MO, where the last service was performed, and requested the free engine replacement under warranty. They acknowledged that the car is covered, but refused to perform the repair because the vehicle is not yet registered. I explained that I have the title in my name and proof of ownership, but cannot register the car in Missouri because it does not run and must pass safety and emissions inspection to be registered. Despite showing them the title and explaining the situation, they continue to deny warranty service. I believe this is unfair and against Kia’s warranty policy, which requires proof of ownership—not necessarily registration. I’m requesting the dealership to honor the warranty and perform the repair, as the issue is known and covered by Kia’s engine recall campaign.

Vehicle now unsafe to drive with failed cylinder that could cause complete engine seizure while driving. Kia had all recommended services and oil changes since acquired in 11/2016. These service records demonstrate the progression of my vehicle's engine issues, from early oil consumption problems documented by York Auto Care in July 2023 (3 quarts low) to complete cylinder 3 failure with zero compression confirmed by Kia's own diagnostic testing in May 2025. Despite this documented history and Kia's own test results showing catastrophic engine failure, they have denied warranty coverage under their engine campaign that specifically covers bearing-related failures on my 2015 Kia Optima 2.4L.

My car was towed to the nearest repair facility and a diagnostics was completed on it revealing a seized engine. My car has been well maintained and has never been in a repair shop for any type of major repairs. This engine failure came as a complete surprise as the car gave no indication that there was a problem.

My 2015 Kia Optima Hybrid poses a serious safety risk. While driving at highway speeds, the car has randomly shut off multiple times. A "Check Hybrid System" or hybrid battery warning appears on the dashboard, and the vehicle either loses power entirely or switches to electric-only mode and coasts to a stop. This happens without warning, putting my life and the lives of others at risk. I already had the relevant hybrid system recall work completed by a Kia dealer, but the issue persists and the car remains unreliable and unsafe. This appears to be a known issue affecting many 2011–2016 Optima Hybrid vehicles. Kia needs to be held accountable for continuing hybrid system failures that occur post-recall and outside of warranty. This is a dangerous, recurring defect.

ENGINE

We are submitting this claim because the engine on the vehicle is completely locked up at only 50,000 miles, despite the maintenance being fully up to date. This issue appears to be directly related to the well-documented rod bearing failure that Kia has previously issued recalls for across various models and years. We have contacted several Kia dealerships in our area—including those in Anniston, Trussville, Huntsville, and even across state lines—seeking assistance. Unfortunately, all of them have refused to proceed with an engine replacement due to the vehicle having an older KSDS (Knock Sensor Detection System) software update. While we have documentation that the original update was completed within the required timeframe, they are now stating that a newer version of the software is required in order to move forward. However, when we reach out to Kia dealerships requesting this updated version, we are told that they cannot perform the update because the engine is already locked—placing us in a frustrating and seemingly impossible situation. We are essentially being told we need the update to fix the issue, but the update cannot be done because of the issue itself. We’ve also contacted Kia Corporate, and unfortunately, the response has not been helpful. We’ve been told that the recall campaign tied to this issue has closed, and that there is nothing more they are willing to do. Meanwhile, we are left with a vehicle that cannot be driven, despite only having 50k miles, and which we are still making payments on. This feels incredibly unfair and potentially unlawful, considering Kia has acknowledged bearing-related failures in similar vehicles. We are simply asking for accountability and support for a problem Kia is well aware of. We are at a complete standstill, with no cooperation from dealerships or corporate.

The contact owns a 2015 Kia Optima. The contact stated that the vehicle was previously included in NHTSA Campaign Number: 20V519000 (Service Brakes, Hydraulic) in October of 2020. The vehicle was taken to the dealer, who tested the vehicle to determine that the vehicle was not leaking brake fluid. Approximately 5 years later the ABS, traction control, and brake light illuminated, causing the vehicle to hesitate and jerk while driving. The contact stated that there was a burning oil odor coming from the vehicle. The contact inspected the vehicle and noticed the modulator valve was leaking oil, causing it to leak out of the vehicle when the cap was removed. The contact noticed oil on the skid plate underneath the oil pan. The vehicle was towed to the dealer, who diagnosed that the ABS module needed to be replaced. The vehicle was repaired. The manufacturer was informed of the failure and opened a case. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 87,600.

I purchased a 2015 Kia Optima Hybrid on [XXX], from Nissan of Grapevine, TX. The vehicle had an open safety recall issued in 2021 (PI2104) related to engine failure, but neither Kia nor Nissan informed me of this recall before my purchase, nor was the recall repair ever performed. On [XXX], my engine suddenly seized while driving, leaving me stranded. I had the vehicle towed to Meineke in Pflugerville, where they confirmed the engine failure but declined to perform an official diagnostic due to liability concerns. In 2024—over a year after my engine had already failed—Kia America finally mailed me a recall notice. By this time, the damage was irreversible. I took the car to Kia of Round Rock on April 2, 2024, where I was charged a diagnostic fee despite the engine failure being caused by the known recall issue. Kia then denied me warranty coverage, claiming I was ineligible because the recall repair had not been performed prior to the failure—even though I was never informed of it in time. Now, my vehicle has been impounded at AusTex Towing since March 6, 2025, because it is inoperable and cannot be registered. If I cannot afford the impound fees, my car will be auctioned off, leaving me responsible for payments on a vehicle I can no longer use. Safety Concerns: -Sudden engine failure while driving poses a serious crash risk. -Failure of recall notification system—I was only informed AFTER my engine had already failed. -Negligence by the manufacturer and dealership—Neither Nissan (the seller) nor Kia (the manufacturer) addressed the recall prior to the failure. I am requesting that NHTSA investigate Kia America and Nissan of Grapevine’s handling of this recall to determine whether their actions constitute negligence in notifying owners about critical safety defects. Kia should be held responsible for either covering the cost of repairs, offering a buyout, or reimbursing me for my financial losses (towing, impound fees, and loan payments).

Thankfully I was able to pull over to safety. I attempted to start again, and the engine started with a weird noise coming from it. I had it towed to my local Mechanic who told me that my engine is part of a safety recall.

The paint on the vehicle is separating from the body. This vehicle is available for inspection at any time. The paint begins to peel and break off when it rains, and it washes into the drains. From there, it ends up on the grass where my young child plays, potentially getting on his hands and into his mouth. Additionally, animals like birds are picking at the paint on the grass. My insurance has verified this problem, and there were no prior signs that indicated any issues. Recently, following a storm, water started bubbling up beneath the paint, causing it to crack and eventually blow off. It started in a small area but with every rain gets worse.

On October 10th 2024, my 2015 Kia Optima caught fire while I was driving. The fire originated from the engine compartment, completely engulfing the vehicle in flames within minutes. Component/System Failure: The exact cause of the fire is unknown, but Kia had previously issued a recall for this model due to an engine defect that posed a fire risk. The vehicle is no longer available for inspection as it was completely destroyed in the fire. However, I have multiple videos documenting the incident, including footage of the fire and the aftermath. Safety Risk: My safety and the safety of others were severely compromised. The fire started suddenly while I was driving, forcing me to evacuate the vehicle immediately. If I hadn’t reacted quickly, I could have suffered serious injuries or worse. Additionally, the fire posed a danger to other drivers and pedestrians nearby. Reproduction/Confirmation: The issue has not been reproduced, but it aligns with the recall Kia issued for this model. Prior to the fire, I attempted to schedule an appointment with Kia to address the recall, but I never received confirmation, and no inspection was performed. Inspections: After the incident, I contacted Kia, and they sent an investigator to inspect the remains of the vehicle. No police or insurance representatives conducted an independent inspection. Warning Signs: There were no warning lights, messages, or obvious signs of a problem immediately before the fire. However, I had previously noticed a recall related to fire risk for my specific model and attempted to schedule an appointment with Kia, but they never responded. Given Kia’s history of engine fire recalls, I strongly believe this incident is related to the known defects in this vehicle model.

The paint started out looking almost "bubbled" but definitely showed serious signs of delamination, quickly after noticing the delamination, the paint flaked off in relatively large pieces all over my vehicle. There is paint missing from the hood, the roof, the back passenger side door, the quarter back panel of the passenger side, and one chip on the driver side door. I reached out to KIA regarding the issue and was told that there is nothing that can be done. I have gotten to the point that i cannot stand to look at the car I once loved so much, it is a shame. KIA is a company that I have been loyal to when it comes to vehicles and I have only owned KIA's since 2008 but after this issue I am almost embarrassed to show up anywhere driving this car.. and even more so I am upset that KIA will not do what it takes to remedy this issue for myself and so many others.
