2016 KIA OPTIMA

LATCHES/LOCKS/LINKAGES:TRUNK LID:LATCH

Kia America, Inc. (Kia) is recalling certain 2016-2017 Rio, 2016-2018 Optima, 2017-2018 Optima Hybrid and Optima Plug-in Hybrid vehicles. The trunk latch base may crack, preventing the opening of the trunk from the inside. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 401, "Internal Trunk Release."

Risk: A person inside the trunk compartment may become trapped, increasing their risk of injury.

FUEL SYSTEM, GASOLINE:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS

Kia Motors America (Kia) is recalling certain 2011-2017 Optima, 2012-2017 Sorento and 2011-2018 Sportage vehicles that previously received an engine replacement under recall number 17V-224, warranty, or the Knock Sensor Detection System (KSDS) Product Improvement Campaign. The high pressure fuel pipe that connects to the fuel pump outlet may have been damaged, misaligned or improperly torqued during the engine replacement procedure, possibly causing a fuel leak.

Risk: A fuel leak in the presence of an ignition source can increase the risk of a fire.

AIR BAGS:FRONTAL:DRIVER SIDE:INFLATOR MODULE

Kia Motors America (Kia) has recalled one 2016 Optima vehicle. In this vehicle, the end seal for the driver's frontal air bag inflator may not have been properly installed, possibly resulting in reduced inflation of the frontal air bag in the event of a crash.

Risk: In the event of a crash, an air bag that does not inflate fully increases the risk of injury.

POWER TRAIN:AXLE ASSEMBLY:AXLE SHAFT

Kia Motors America (Kia) is recalling certain model year 2016 Kia Optima vehicles manufactured November 13, 2015, to April 23, 2016 and equipped with a 2.4l engine. The right front axle driveshaft may crack and fail.

Risk: If the driveshaft cracks and separates from the vehicle, it will not be able to move forward. Additionally, if the parking brake is not applied upon exiting the vehicle, the vehicle may roll. Either scenario can increase the risk of a crash.

ELECTRICAL SYSTEM

The headlights and brake lights have been VERY dim for a while. I've had to replace both headlights and brake lights an excessive amount in the last several years. This year alone since December 2024, I've had to replace my headlights 3 separate times. I do not drive more than 10,000 miles per year, or use my vehicle on roads that would lead me to believe the issue is from road conditions.

Engine Is knocking that happened when I took my car 3 times to emission test and my car didn't pass after that I took it to my mechanic for the diagnostic and he told me you have to take it to kia dealer but I was shocked the way how they treated me and they completely refuse to replace my engine they came up with too many excuses and I have recall repair active I have right to fix my car but they didn't with bad attitude

ENGINE

Engine began jumping during driving and loss power. No dashboard illumination warning lights and the temperature gage showed normal operating temperature. Car was not accelerating properly. Had to maneuver carefully to prevent being ran over. Engine light illuminated showing misfire. Replaced ignition coil pack and spark plugs. Driving again, car stalled. No dashboard warning lights. No high temperature on gauge. Narrowly missed being hit by a semi as there was absolutely no warning and we were on an Interstate bypass ramp with nowhere to pull over!! Towed car to dealership for diagnosis. Results: engine blown, turbos gone, and the catalytic converter is holding oil. Dealer is stating this is not covered under the extended warranty from Kia as its not connector rod bearing issues and that the piston rings failed. However, they stated the turbos got "too hot" and they failed. The gauges have never shown that the car was running hot. I have a sworn statement from my mechanic stating this is absurd and a valiant attempt to not pay for what would be the second warranty replacement of my engine. The piston rings failed as a result of the connector rod bearing failure. The "too hot" temperature that damaged the turbos was likely caused by the same bearing issue. The heat from the bearings unseated the piston rings and allowed the engine to dump its oil causing the engine to fail. I highly recommend that you open an investigation into these issues. The car not accelerating and losing power at interstate speeds is a very serious and dangerous issue.

ENGINE AND ENGINE COOLING

The contact owns a 2016 Kia Optima. The contact stated that while driving approximately 75 MPH and attempting to accelerate to overtake a semi-truck, the vehicle suddenly started losing automotive power and then stalled. The vehicle was towed to the local dealer, who diagnosed that the engine had seized and needed to be replaced. The vehicle was not yet repaired. The contact indicated that prior to the failure, the check engine warning light illuminated and remained illuminated, and the engine experienced excessive oil consumption. The manufacturer was not yet notified of the failure. The failure mileage was 45,000. The VIN was not available.

FUEL/PROPULSION SYSTEM

I am filing this complaint to urgently bring attention to a serious safety and mechanical defect with my Kia vehicle's engine and fuel system. My engine is excessively consuming oil, to the point where it poses a significant risk of engine failure, which could result in a loss of power while driving and create a hazardous situation on the road. Details: I consistently have to add 5 quarts of oil approximately every month. During regular oil changes, there is barely any oil recovered from the engine, suggesting the oil is being consumed or burned internally. I took the vehicle to AutoZone for diagnostics, and they confirmed the engine is burning oil. They also mentioned it could be related to a rod or piston ring issue. There are no visible leaks under the vehicle, and the oil is not being expelled externally—it's being consumed by the engine. This issue is not normal wear and tear. It's a systemic engine defect that is causing rapid oil loss and is likely to lead to engine seizure or failure if not addressed. This level of oil consumption is not just expensive—it is dangerous. A sudden loss of engine power could cause an accident, especially at highway speeds. I am deeply concerned for my safety and the safety of others on the road. Urgency: I am requesting the NHTSA to investigate this issue and consider initiating a recall for affected Kia vehicles. I am not the only one facing this problem—online forums and consumer reports are filled with similar complaints from other Kia owners. This is a critical engine/fuel system safety defect that must be addressed immediately before someone is injured or worse due to engine failure while driving. Thank you for your time and attention to this matter. I am available to provide service records, photos, and further documentation upon request.

The engine is starting to fail causing issues such as being able to accelerate. When driving on the freeway it caused a safety issue it began slowing down on the interstate. The vehicle has been inspected by mechanics. No warnings prior to problem. They appeared day before due for an oil change. The car also burns oil really fast sometimes causing car to smoke. I have a GDI turbo engine and have been told that the engine i have has been recalled a few times on different models cars.

ENGINE AND ENGINE COOLING

The contact owns a 2016 Kia Optima. The contact stated that while driving at 45 MPH, there was a misfire coming from the engine, and the vehicle was shaking. There was no warning light illuminated. The vehicle was taken to an independent mechanic to be diagnosed. The vehicle was diagnosed with engine failure due to piston rings failure, causing coolant intrusion into the engine. The contact was informed that the engine needed to be replaced. The contact stated that the ignition coil, cylinder #1, and spark plugs were replaced. The dealer was contacted, but had not diagnosed or repaired the vehicle. The manufacturer was not made aware of the failure. The failure mileage was approximately 100,000.

ENGINE

My 2016 Kia Optima EX (VIN [XXX] , 2.4L I4 DI) suffered sudden engine bearing failure and complete engine seizure after approximately three months of use. After inspection, the Kia Scottsdale dealership confirmed that my vehicle’s VIN was eligible under the engine replacement warranty and submitted a request for assistance.However, Kia America denied the request. This defect is identical in nature to the known dangerous defect covered under Kia Safety Recall SC147 (NHTSA 17V-224) and related recalls for earlier Optima model years, involving connecting rod bearing wear leading to engine seizure. In my case, the defect caused a total loss of motive power, posing a serious crash risk. Kia Motors America has refused to repair or replace the engine, claiming my vehicle is ineligible due to being purchased from an auto auction (Sierra Auction) and having multiple prior owners. This refusal ignores that the defect is a safety-related manufacturing flaw identical to those already acknowledged by Kia and subject to federal recalls. I request NHTSA investigate Kia’s refusal to extend the same safety remedies to my VIN and consider whether the scope of SC147 and related recalls should be expanded to include vehicles with the same defect pattern. Supporting documentation available upon request. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving at approximately 45/50 mph, the right rear window suddenly dropped into the door panel without warning. This unexpected failure startled me and created a distraction while driving, as well as compromised my ability to hear and concentrate safely. My left rear window has also slipped into the door panel and is now being held up by shims and I have now discovered that the issue is due to a failed window regulator. This is a known issue in similar vehicles and poses a potential safety hazard, especially during adverse weather or high-speed driving. The Manufacturer has not issued a recall only a bulletin and the cost that was quoted to me from Hendrick Kia of Concord was over $900 dollars a regulator.

Complaint Message – 2016 Kia Optima Engine Failure Without Oil Light Warning I am the owner of a 2016 Kia Optima (VIN: [XXX] ). My vehicle suffered complete engine failure due to oil starvation — without any prior oil warning light or indication. The engine died while driving, and it was only afterward that I discovered the engine oil was extremely low. The oil pressure light never illuminated at any point to warn me. I am aware that Kia previously recalled earlier model years (2011–2014) for similar engine issues under Recall SC147 and others, related to the Theta II engine and oil pressure-related failures. Many owners reported the exact same symptom — catastrophic engine failure without oil light warnings — that I am now experiencing in my 2016 Optima. Although my model year is not included in the existing recall, the failure pattern appears identical. I believe this presents a significant safety issue that should be investigated. A critical warning system (oil pressure light) failed to function properly, which directly led to engine damage. I am requesting that this issue be reviewed and investigated by NHTSA and Kia for potential expansion of the recall or warranty coverage to include the 2016 Optima. I have already contacted Kia and am pursuing further review through the dealership and customer support. Please note that other 2016 Optima owners have reported similar complaints online and in forums, and this issue may affect a broader number of vehicles than currently acknowledged.

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

Several safety-critical systems failed on this vehicle. The engine (Theta II 2.4L GDI) failed due to rod bearing wear, causing sudden power loss on the highway. The vehicle entered limp mode, once at 50 mph in 2018 and again at 70 mph in 2025, and had to be pulled over quickly to avoid collision. Additional issues: all four windows failed at different times, leaving them stuck open and creating safety risks in weather or emergencies. The trunk latch failed, causing unsecured cargo risk. ABS, TPMS, and traction control warning lights illuminated repeatedly, indicating possible loss of critical safety systems. A loose wiring harness caused the turn signal bulb to burn out repeatedly, reducing visibility and signaling. The dealership performed the KSDS software update after I reported engine trouble but did not resolve the issue. The engine soon failed completely while driving. Other issues, such as the fuse box blowing fuses from a standard USB charger have also been documented by a Kia dealership but not always fully repaired. The most recent engine failure and electrical defects are being inspected by a Kia dealership, and Kia Consumer Affairs is reviewing the warranty claim. Prior to the engine failure, I smelled burning oil and topped it off monthly due to excessive consumption. The oil level light and check engine light only appeared during limp mode right before the failure. These repeated safety-critical defects, particularly sudden engine failure at highway speed, created a significant safety hazard for myself and others on the road. At the time of this report, I am in the process of seeking warranty coverage for the catastrophic engine failure through Kia. The failure behavior (limp mode, flashing check engine light, and rod knock) is consistent with the safety defect described in the Theta II engine settlement. I am concerned that despite this being a known issue, there may be delays or denials in honoring the safety-related warranty repair.

I own a 2016 Kia Optima EX with VIN [XXX] . The engine failed at 85,763 miles due to a rod bearing seizure. This matches the known defect in Kia’s 2.4L GDI engines, which has been the subject of recalls and service campaigns in the past. Despite being covered under Kia’s extended engine warranty, Kia America denied my engine replacement claim. They cited "vehicle reconditioning" and "multiple ownership" as reasons — neither of which are valid grounds to void warranty coverage, especially for a known defect. A certified Kia dealership (Mark Kia in Scottsdale, AZ) approved my vehicle for warranty replacement, and submitted the request. Kia corporate denied it. This creates a serious safety concern and shows that Kia may be wrongfully avoiding responsibility for this defect. Please investigate.

All 4 of the window regulator motors blew in my windows at the same time, only about 9 years into the vehicle's life. The little plastic pulleys that move the cables degrade over time and then ruin the rest of the window motor when they break, and since they decided not to make this an easily repairable part it requires the entire window regulator assembly which is half of the door to be replaced, not just this plastic part. I had to replace all 4 of them out of my own money, KIA REFUSED to replace something that is completely 100% their fault and it cost me over $3,500 to repair all four windows that went out pretty much at the same time. It's insane silly that anyone's windows can just break at anytime and be stuck in the down position. I can't just put up trash bags and then not be able to see a thing while I wait to get it fixed if it happens again. I was lucky enough to be in a position to get it looked at quickly, but it is absolutely insane that KIA would refuse to cover such a defect. There is already a class-action lawsuit over this I believe but they haven't even attempted to remedy the situation. Not everyone has time to wait for a lawsuit to settle. There should absolutely be some kind of recall/extended warranty on their windows. My engine blew at 57,400 miles only a few months later which is separate and was replaced but it's just insane that I was promised a car but got a piece of trash that consistently breaks while all I can get is a replacement engine with the same exact problem and no confirmation that the same thing won't just happen again while they continue to use the same defective engine over 10 model years. I want them to fix their issues not slap a band-aid over them and hope for the best. This company has been knowingly selling cars built to end up in a landfill within 10 years and they don't care.

I want them to fix their issues not slap a band-aid over them and hope for the best. This company has been knowingly selling cars built to end up in a landfill within 10 years and they don't care.

I went to the Garden Grove Kia to get my new 2016 kia optima repaired for their knock sensor settlement repair. By their own terms of the agreement all original and subsequent ow ers can get vehicles repaired. They took my vehicle information, I gave them all details of my ownership of the vehicle and they said they would fix it. The next day I rented a trailer to take the vehicle to get repaired (vehicle still runs but don't think it's safe to drive like that) and upon arriving, a worker comes out and tells me that they will not repir the vehicle because I just purchased the vehicle. Craig, the manager, also refused to see ownership documents but gave me 2 things; legal advice saying that I should sue where I bought the vehicle from and a paper that said they will not fix cars owned by dealers and auctions. I am neither am neither nor. Craig, also stated that Kia wont cover the repairs.

The check engine light came on in the car. Upon having it checked at a local automotive shop, we discovered that the thermostat assembly is malfunctioning. This can cause the engine to overheat and shut off at any time which of course would be a severe danger. Additionally, a bad thermostat assembly in Kia vehicles can lead to engine overheating or overcooling, potentially causing engine damage and even a fire risk. Upon searching, this appears to be a common issue with the 2016 Kia Optima.

I was driving on 295 and my engine light came on. My car started shaking when I was accelerating and when I don’t accelerate it stops. When I come to a complete stop the car jerks back and forth acting like it wants to stall… I’m waiting on a call back from my mechanic on their diagnostic results

ENGINE

1. Burning Oil Issue: I began noticing excessive oil consumption in my vehicle at approximately [130,000], with the need for frequent oil top-offs. I made multiple visits to my local dealership and reported the issue, but no lasting solution was offered. This burning issue is a known issue due to position ring failure. 2.Catalytic Converter Failure: Due to the excessive oil burning, the oil eventually began to damage the catalytic converter. This caused significant issues with the performance of my vehicle, including [specific symptoms such as loss of power, poor acceleration, engine misfire, etc.]. 3.Engine Failure: As the oil-burning issue continued, the damage to the catalytic converter worsened, leading to a total engine failure. I am left with a car that is no longer operational, and I believe that these issues are the result of a persistent defect in the engine that should have been addressed under warranty or a recall.

There is a clean slit on my dashboard where the passenger airbags are it’s started to form a complete square around the air bag placement and I’m worried it might have a problem with the airbags and its not just cosmetic. When I googled the issue there are tons of kia drivers with the same clean sit appearing over the passenger air bag. I contacted Kia dealership and they said I’d have to pay for a diagnostic fee to determine if it’s a problem but there’s clearly a problem with the 2016 kia so I’m sure all of us owners would appreciate it being recalled
