Each component in detail
What the reports in each category say, in the owners' own words
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
My Kia experienced catastrophic engine failure while I was driving on the freeway, creating an extremely frightening and dangerous situation. The sudden loss of engine power put my safety and the safety of surrounding motorists at risk, as I was traveling at freeway speeds when the engine gave out. Leading up to the failure, my vehicle experienced excessive oil consumption despite regular maintenance. I was repeatedly adding oil between scheduled oil changes. Previous repairs, including replacement of spark plugs and a thermostat, did not resolve the underlying issue. Following the engine failure, a Kia dealership reported a cracked engine valve and multiple severely damaged or melted spark plugs, including spark plugs that had recently been replaced. These findings raise serious concerns about progressive internal engine damage and a potentially defective engine. Despite my concerns regarding known Kia engine defects and possible connecting rod bearing issues, the dealership stated it could not perform the bearing clearance test due to the condition of the valves. My case was never submitted to Kia Techline for further investigation. I was initially instructed to provide oil change and maintenance records for consideration of engine replacement assistance, only to later be told that excessive oil consumption was not relevant to my claim. I am extremely concerned that a potentially defective engine experienced progressive damage before suddenly failing on the freeway, placing my life and others at risk. I am requesting that NHTSA investigate this failure and determine whether it is related to known Kia engine defects or an unresolved safety issue affecting other vehicles.
My engine is making a knock sound coming from the bottom end of motor I was driving it and no warning or anything it just started knocking
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
I am reporting a serious safety concern involving my 2016 Kia Optima, purchased from CarMax in 2024 and financed through CarMax Auto Finance. On or about October 5, 2026, I returned to my parked vehicle and discovered extensive black soot/smoke residue throughout the interior. Wiring and interior components appeared melted or burned. The vehicle had not been involved in a collision. Based on the damage, I believe an electrical or wiring failure may have caused the fire, although the exact cause has not yet been confirmed. The vehicle was inspected by police and the tow operator, and it was determined to be a total loss. An insurance claim has been filed, and the vehicle should be available for inspection if requested. This vehicle also had a significant history of mechanical problems. Since shortly after I purchased it, it experienced severe oil consumption/oil loss, requiring multiple visits to CarMax and multiple 1,000-mile oil-consumption tests. I also experienced repeated spark plug and coil pack problems requiring repairs/replacements. The exact component that failed is currently UNKNOWN. I have not yet had Kia inspect the vehicle or confirm the cause of the fire. This incident created a serious safety risk because the vehicle appears to have caught fire while parked. If this had occurred while I was driving or while my children were inside the vehicle, the fire could have caused serious injury or death. I do not recall receiving a specific warning message immediately before discovering the damage. The vehicle did, however, have its history of ongoing mechanical problems described above. I am requesting that NHTSA investigate whether an electrical, wiring, or other safety defect could have caused this vehicle fire and whether other Kia Optima owners may be at risk.
3 times windows different ones has stopped rolling up/down. 3 motors purchased and installed.
Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.
From owner reports, verbatim
Severe engine defect (Theta II 2.4L GDI). Sudden total loss of power, metallic knocking, severe oil consumption, and imminent catastrophic failure while driving, creating a high safety risk. Vehicle is currently out of service in [XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Vehicle was purchased in 2023. AC blower failure occurred for the first time in June 2024 and was repaired by PepBoys. On 4/2/2025 the ve3hicle had an active recall event when the engine seized on the highway because of a faulty oil pump/filter, Engine was replaced 4/17/2025 under that recall. Kia advised at the time that the wiring harness should be replaced due to electrical issues at the time but said that there was no recall for that work. At the time, there were no electrical failures of steering, brakes, all power etc. Nor did we know that those were a possibility. The wiring harness quote was $7,000, over the cost of the vehicle. It was decided to continue repairing the electrical issues as they came up, it was assumed that the fuses would blow before there because a safety or total vehicle failure, as automobiles are designed that way. 8/4/2026 the vehicle experienced a complete and total loss of power resulting in a traffic crash into another vehicle as the brakes felt like you were trying to push a wall rather than a pedal. There was minimal physical damage to the other car and the kia, the other driver got my husband's insurance information and then drove off. The car did startup after ~30 minutes or so and was driven home, but taken to the Kia dealership the next day. It was said that the blower motor overheated and melted a portion of the electrical junction box under the hood and that it was unsafe and dangerous to drive. Kia said that there were no active recalls for this work. NHTSA SC351 seems very similar to this issue that has plagued this car since the beginning. We would ask that Kia incorporate this vehicle and others outside of the year/model ranges in SC351 that have similar failure mechanisms as this seems common.
Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
The contact owns a 2016 Kia Optima. The contact stated that while driving 25 MPH, the vehicle shut off without warning. Soon after the failure, the engine caught fire; however, the fire dissipated independently. The insurance agent was contacted and arrived at the scene to inspect the vehicle. The contact was initially informed that the vehicle was safe to drive; however, the engine failed to start after several attempts. Due to the failure, the vehicle was towed to a dealer where a mechanic discovered that the knock sensor was inoperable and had caused the fire. The contact was informed that the vehicle was included in NHTSA Campaign Number: 18V907000 (Fuel System, Gasoline, Engine) and the vehicle was repaired under the recall. Nearly a month after the repair, the vehicle started consuming oil with the master warning light displayed. The vehicle was taken back to the dealer for an inspection; however, no fault was found with the vehicle. The manufacturer was notified of the failure, and the contact was referred to the dealer. After another inspection, the dealer agreed to replace the engine; however, the failure recurred after the repair.
My 2016 Kia Optima equipped with the 2.4L DOHC I4 GDI engine began to experience progressive and severe oil consumption during the latter part of my ownership. The oil warning light began activating repeatedly, even after shortly getting the oil changed. Several certified mechanics and oil change service stations told me this was an ongoing issue with this car and engine and that there was nothing I could do but monitor it and keep it filled. At their instruction, I monitored and had it changed more frequently, often topping it off at the oil change station and at home when needed. Approximately 2 weeks after an oil change upon putting the car in reverse it started to shake uncontrollably. The car was towed to a mechanic who stated I needed an engine. I then towed it to an authorized Kia franchise dealership where the technician documented the oil consumption complaint, confirmed a Cylinder 2 misfire code, performed a borescope inspection, and found the Cylinder 2 exhaust valve burnt with a chunk missing. Engine replacement was recommended by the Kia dealership technician. Prior to my purchase, the engine had already been replaced at approximately 80,000 miles under recall-related circumstances. The replacement engine installed by a Kia dealership subsequently failed, exhibiting symptoms consistent with the documented widespread defect affecting the 2.4L DOHC I4 GDI engine in 2016 Kia Optima vehicles, including severe oil consumption, cylinder misfire, and catastrophic internal engine damage confirmed via borescope at a Kia franchise dealership. Kia America denied the claim based solely on mileage despite the damage being confirmed by their franchise technician. My vehicle became unsafe to drive due to this engine instability shortly after starting before becoming fully inoperable. My vehicle has been non-operational for approximately 5 months. Kia has not provided a substantive written determination despite a formal written demand submitted in March 2026.
Exterior lighting
Reports naming headlights, tail lights, turn signals and other exterior lighting.

The engine is a problem and all I’m ever told us “ this vehicle is know to have engine problems. This is dangerous to have in the road. Kia is aware of this. Why sale the vehicle knowing this and not disclosing this info to the consumer upon purchase. There is no truth in lending. It’s plain sight robbery. What if I’m far from home and stranded because vehicle set fire or broke down in hazardous condition weather. I constantly needing oil changes because of this engine. The dealership is aware. They tell me to trade it in or get rid of it because it’s going to go for a fact. I’ve never missed oil changes. I put oil every time the oil indicator light comes on. Now for the 3rd time the check engine light is on. 2 times for misfire code. The vehicle engine holds sludge no matter how much you get oil changes. The mechanic told me this year make and model is known for this very fact. I want my money back. Kelly blue book don’t give enough. I was scammed into this car but I managed to pay it off. A car the sales person scammed me and wouldn’t take the vehicle back. I complained to the general manager. They always act like he wasn’t available. They kept claiming new ones started. After almost a year of those games I had to move and the case never got solved. But even when I complained their maintenance person stole my rims. They told me prove it. Just all bad experience. I just want my money. Even if they gave me another engine. It’s still going to be the same problem. A bad engine. 2016 Kia optima’s should not have been continuously sold with them knowing it has bad engines. Even the headlights don’t work. Very dim. Car smells like burning fumes when driving. Please please help. This isn’t fair lending practice. People trust them and they are dishonest sellers.
Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
The contact owned a 2016 KIA OPTIMA. The contact stated that while driving at 30 MPH occupied with her husband the contact heard a noise coming from the rear of the vehicle and smoke coming from the rear of the vehicle as you looked in the drive side rear view mirror and while depressing the brake pedal attempting to come to a complete at the traffic light, the brakes failed to work a intended. No warning light illuminated. The contact mention she kept trying to depress the brake pedal, however the vehicle kept accelerating causing the vehicle to crash into a ditch, go around a telephone poll, crashing into a rock garden which allowing the vehicle to come to a complete stop. The vehicle was towed to a towing lot call interstate towing then the vehicle was then towed by insurance company to a collision center. No injuries were sustained. No medical attention. The fire department extinguished the fire. The contact stated a police report was filed. The vehicle was destroyed. The manufacturer was not made aware of the failure. The approximate failure mileage was 166,834.
1) Rear passenger window failed a couple months ago. I believe it was regulator, not 100% sure. Cost me a couple hundred to fix. Now, few months later, the driver side rear window has failed. I rarely use the windows so I believe the failing parts are Kia known manufacturing defect. The dealer acknowledged that it’s a known problem with the vehicles like mine and even suggested the other one is going to fail soon. Now it has. If the dealership is aware then it’s likely a Kia flaw. If it’s a know manufacturing flaw, shouldn’t Kia should be fixing them instead of making customers spend upwards of $1k+ to fix both windows? 2) cruise control cuts off or doesn’t set and menus won’t go back to speedometer. While trying to set cruise control, it gets into the menu and won’t go back to the speedometer. Sometimes I have to pull over and stop to get the cruise control to work again. It gets stuck in the menu and can’t see the speedometer. Might get stuck on the trip screen, or the range. This has been happening since about 75k miles. It also doesn’t work with the pedal to set sometimes. Messing with it while driving can be a real hazard and sometimes I need to have cruise control to work. It’s deforming more than just inconvenient
Body & structure
Reports naming the vehicle structure, frame, body panels, doors, hood and trim.
From owner reports, verbatim
Component: Power Window / Door Description: All four power window regulators failed on my 2016 Kia Optima SXL within 16 months - from June 2025-Oct 2026. The failure mode is identical on all four doors: the plastic drum gear in the regulator separates or breaks, causing the window glass to drop into the door and become completely inoperable. The vehicle had 113,867 miles on it at the time of the first failure. This is a known design defect, not wear-and-tear. Kia issued Technical Service Bulletin BOD300 (March 2021) specifically addressing "Window Regulator Drum Gear Replacement" for 2016-2017MY Optima (JFa) vehicles produced September 1, 2015 through July 31, 2016. The bulletin confirms the drum gear separates or breaks. Despite this, Kia has not issued a safety recall. Safety risk: In a collision, intact side windows are an occupant ejection restraint. A window that has fallen into the door removes that protection and increases the risk of occupant ejection. Side curtain airbags deploy through the window frame (FMVSS 208). A window that is detached or lowered can interfere with proper airbag deployment, negating a Federal Motor Vehicle Safety Standard protection. In an emergency (fire, submersion), the driver and passengers cannot lower a window to create an escape path. Evidence of systemic defect: All four regulators failed (not one or two), within a short timeframe, demonstrating a design-level failure rather than isolated component wear. Kia's own TSB BOD300 confirms the root cause (drum gear separation/breakage). This complaint is filed in connection with existing NHTSA investigations PE21004 and EA22002 regarding this exact defect. I paid $3,734.64 out of pocket to have all four regulators replaced. I opted out of the Le Beau v. Kia America class action settlement and retain my individual claims. I am requesting that NHTSA evaluate this as a safety defect warranting a recall.

Visibility
Reports naming windshields, glass, wipers, defrosters and mirrors.
From owner reports, verbatim
Concerning my Optima KIA's OEM front windshield. At certain times of the day when the sunlight is shining on a certain angle it is difficult to see through the windshield due to the glare which creates a visual impairment. There were a quite a few instance's where I almost got into serious accidents. With my observation the glass looks like there are thousands of microscopic pits like a light sandblasting embedded within the lamination and not the surface of the glass. It seems prominent at night also. This seems like a manufacture defect. This puts a safety risk for me and others. The dealer and manufacture will not do anything about it do to out of warranty. This appeared about a year ago and has gotten worse.
Window falls into the door. The rear two windows have been repaired 3 times. They are currently both broken again along with the front drivers side. I currently have three windows being help up by tape. They are taped to the frame of the door to stop the window from falling into the door. I don't know why this wasn't a recall. I see there is a TSB BOD300. The dealership repaired once but never informed me about the known defect.
Airbags

While driving at highway speeds on the freeway in San Diego, the engine of my 2016 Kia Optima catastrophically seized without warning. I instantly lost all power steering, brake assist, and electrical power, creating an immediate life-threatening emergency. The vehicle was towed to a Kia dealer. Corporate Techline and the dealership are refusing to perform the mandated settlement rod bearing test and are falsifying paperwork to deny the safety remedy.

I purchased a vehicle from Banter Auto here in Wichita, Kansas. I reviewed the Carfax beforehand and nothing stood out that scared me so I signed off and purchased the vehicle. I have had nothing but problems since buying which was 7 months ago and have spent $9000 on repairs. I’ve been told by several mechanics the last 5 times I’ve been in and out of mechanic shops it’s evident my car sat in deep water for a long period of time. I finally took it to an electrical auto specialist here in town and while he said it is evident my vehicle sat deep water for a period of time and while the corrosion hasn’t quite started to cause an electrical problem that it very well could down the road. I’ve given the man who owns the dealership and opportunity to make this right however he stopped responding. I believe that is illegal and I’ve been told it should’ve been a “flood title”. I will know for sure after seeing a I will know for sure after seeing an attorney this week. That was not disclosed to me or I would definitely would have not purchased the car. When I first got the car, the locks and windows were going insane flickering all over the place and Kia dealership told me it was quite crazy and nothing they had seen before, however, they were able to fix it. I strongly believe that when my car was flooded it caused something to happen that I’m only going to have to keep paying for overtime. I’m already in debt from the $9000 I’ve had to getting personal loans. This is causing me enormous emotional distress. Please help.
MDPS failing when driving randomly. Steering locks up and vehicle is uncontrollable, while the vehicle is moving. This has occurred at varying speeds, while turning and while driving straight. Dealer has unsuccessfully got the issue to replicate, but independent service center was able to replicate it and found the extended warranty and recommended dealership visit since issue is covered. Vehicle has been inspected by dealership and the first recommended battery replacement, but this did not remedy the issue. EPS warning light is illuminated while issue is occurring but due to safety, car needs to be restarted to gain control of the vehicle and light turns off.
