My 2024 Kia Niro Hybrid has experienced multiple issues that I believe should be documented. The vehicle previously displayed an Electronic Parking Brake (EPB) warning. It was taken to an authorized Kia dealership for diagnosis and repair. Although repairs were performed for the EPB-related issue, I am submitting this report so the condition is documented if similar reports are being received from other owners. In addition, the vehicle developed a persistent creaking/clicking noise during forward driving. The noise was not present when the vehicle was new and began after normal use. It is most noticeable during forward driving and is not heard while backing up. The vehicle has been inspected by an authorized Kia dealership on multiple occasions, including a ride-along with a technician. After evaluating the vehicle, the dealership advised that the noise was normal and that the vehicle was functioning as intended. No additional repair was recommended. Although the dealership concluded the noise is normal, I remain concerned because the noise did not exist when the vehicle was new and has persisted. I am submitting this complaint so NHTSA has a record of the issue and can determine whether other owners are reporting similar conditions that may warrant further review.

I am submitting this complaint regarding a repeat failure of the Active Air Flap System on my 2017 Kia Niro, which I believe raises a broader safety and reliability concern. On XXX, my vehicle displayed a check engine light and “Check Active Air Flap System” warning. An authorized Kia dealer, Huffines Kia Corinth in Texas, diagnosed the issue and replaced the active air flap assembly (listed on the repair order as “FLAP ASSY–ACTIVE AIR”) at approximately 87,638 miles. At around 105,000 miles, the same warning and check engine light have returned, indicating that the Active Air Flap System is again malfunctioning despite the prior repair and part replacement. This suggests either repeated component failure or an underlying design or control issue that was not resolved. Owners of Kia Niro and related Hyundai/Kia models frequently report similar Active Air Flap System warnings and related diagnostic codes, and Kia has issued technical guidance addressing inspection, cleaning, and software behavior for this system. Although these issues may not yet be the subject of a formal recall, the pattern of repeated failures across multiple vehicles points to a systemic problem in a component tied to engine cooling and efficiency, which can reasonably affect safety, emissions, and vehicle reliability. I am asking NHTSA to review Kia’s handling of Active Air Flap System failures on the Niro and related models, including repeat failures after dealer repair, and to consider whether this issue warrants further investigation or recall/extended coverage action.

Re: Driver Safety Downgrade Stemming from Recent Software Update Complicating Tire Pressure Display Accessibility I am writing as the owner of a 2025 Kia Niro HEV to express my concerns regarding a recent software update that altered how tire pressure information is accessed on the instrument cluster. Prior to the update, tire pressures were available through the steering wheel page button, allowing drivers to view this safety-critical information with a single press and a quick glance. After the update, the tire pressure screen was removed from the page sequence and relocated into a deeper Vehicle Information submenu that requires multiple button presses and menu navigation. This change has created a significant safety issue. Tire pressure can only be displayed while the vehicle is in motion, yet the update now requires the driver to divert attention from the road to navigate several screens in order to access it. This is a clear regression from a human factors and safety standpoint. The previous method was intuitive, efficient and aligned with safe driving practices. The new method increases cognitive load and driver distraction at precisely the moment when attention should remain on the road. I respectfully request that Kia reevaluate this change and consider restoring tire pressure visibility to the steering wheel page button or another single-action, high-visibility location. Tire pressure is not a secondary diagnostic item; it is essential real‑time safety information that should remain immediately accessible. I appreciate Kia’s commitment to innovation, but updates that alter established safety workflows should be communicated clearly and designed to not be at odds with a driver's attention to the road. I hope Kia will take this feedback seriously and consider adjustments in future software releases. Thank you for your attention to this matter.

There's a problem with the horn in my car. Either the high or low. The problem is intermittent and the horn will fail and it is not available in emergency situations. I brought this to the dealership and made them aware but they refuse to take this seriously and two adequately evaluate the car. They blew the horn and said it was working. It was not working and I said it was intermittent and they said well we could not find any problem. There were no warning lights. Nothing else. The horn is just intermittently failing.

The Hydraulic Clutch Actuator has caused functional driving issues and caused my vehicle to go into limp mode. I was never informed of the recall issue prior to purchase, and the recall was marked as complete, when it was not. The fix for KIA NIRO Recall SC276 was incomplete in January 2024, and I purchased my vehicle in April 2024. My issues started in November 2025, and the incomplete recall issue has been ongoing. KIA offers only a 1/2-way fix, and this is simply not acceptable.
NHTSA complaint #11743671 — an unverified report by a vehicle owner.
The AC compressor failed due to an isolation resistance failure at the high voltage inverter. Freon leaked from the AC system into the battery chiller coolant loop, causing crystallization and blockages in the inverter coolant circuit. This is a battery thermal management system failure. The failure was confirmed and diagnosed by an authorized Kia dealer. Warning lights appeared on the dashboard including an inverter coolant warning. The vehicle was driven in ambient temperatures exceeding 108 degrees Fahrenheit in Arizona with no cabin cooling and a compromised battery thermal management system, creating a safety risk to the driver. The dealer quoted repair including AC compressor replacement, battery chiller replacement, and inverter coolant flush. Kia Consumer Affairs denied warranty coverage under the federal emissions warranty despite the vehicle being within the 8 year/80,000 mile coverage window at approximately 58,309 miles. No written explanation for the denial was provided. This failure appears to be a known pattern on this platform based on owner reports. The battery chiller and inverter coolant system are integral to battery thermal management and should be covered under the federal emissions warranty. The vehicle is currently unsafe to operate in extreme Arizona heat without functioning thermal management.

I am writing to request assistance regarding a recurring issue with Recall SC276. Approximately two years ago, I had the hydraulic clutch actuator (HCA) replaced by a dealership as part of this recall. Since then, the vehicle has been driven only 10,000 miles, bringing the total mileage to about 45,000. The vehicle recently broke down, and the dealership confirmed that the replacement HCA has failed. Despite this being the same part addressed by the recall, the dealership quoted $1,700 for the repair, and Kia has declined to cover the cost. I believe Kia should be responsible for this replacement, as the recalled part was intended to provide a long-term solution to a safety issue. I would appreciate any help you can provide in ensuring Kia covers the cost of this repair.

The vehicle just shut down as I exited. The power and gas pressure decreased. Pulled over to see if my hybrid battery was defective or drained. It wasn’t. A notification popped up and said “Hybrid Control System or Low Voltage DC/DC Converter, Contact dealer for service. Finally got it towed to Kia of Valencia the next day and they said it was “Hydraulic Clutch Actuator” and they want charge me $2200 to fix it. But looking up the part, it says there’s a recall for that exact problem.

am writing to formally request assistance regarding my Kia vehicle which I purchased used at approximately 38,000 miles. Shortly after purchase, the vehicle became undrivable and has since required repeated repairs without resolution. To date, the vehicle has been presented for repair on six separate occasions for the same issue and has remained out of service for a significant period of time. Based on these repeated failures and lack of resolution, the vehicle may reasonably be considered defective at this point. Despite being unable to use the vehicle, I have continued to make monthly payments, resulting in considerable financial hardship. In an effort to resolve this matter, I consulted with a Maryland MVA investigator, who advised me to contact Kia directly and report that the vehicle appears to have been sold with a pre-existing defect. I have also communicated with the selling dealership, Eastern Motors; however, I was informed that due to changes in management, they are unable to provide further assistance and consider the matter outside of their control. Additionally, I have previously reached out regarding this issue and have not received a response. Given the timing of the failure, the repeated unsuccessful repair attempts, and the extended period the vehicle has been out of service, I respectfully request that Kia conduct a thorough review of this matter. I am respectfully requesting Kia’s assistance in resolving this matter. Specifically, I would like to explore options such as a replacement vehicle, repurchase (buyback), reimbursement of payments made, or other goodwill support. I remain open to a fair and reasonable resolution. Please advise what documentation or additional information is required to proceed. I am prepared to provide all relevant records, including purchase documentation and complete service history. Thank you for your prompt attention to this matter. I look forward to your response.

On now 4 occasions--intermittently my car will go into drive when shifted into the reverse shift I don't know what component is impacting this. My safety and others safety is at risk by my car literally going forward when it's supposed to be in reverse. I've taken my car to the dealership two times and they have not been able to recreate it or fix anything. I've reached out to KIA corporate for a resolution but have not gotten follow up: Case#XXX (case where I was supposed to get a response from a case manger) and XXX (original case). To my knowledge I don't know if it's been inspected by the manufacturer, police, insurance representatives or others No warning lamps or signs. It happens intermittently and seemingly no rhyme or reason when it happens. This happened back in November 2025 and most recently this April.

I own a 2021 Kia Niro. The rear backup camera intermittently fails to operate. When shifting into reverse, the display screen will either go completely black or the camera will not activate at all. This issue occurs unpredictably and without warning. As a result, I am unable to see behind the vehicle when reversing, which creates a significant safety concern. The lack of rear visibility increases the risk of a collision, especially in areas with pedestrians, children, or low-visibility obstacles. I am aware that similar rearview camera failures have led to recalls for certain Kia Niro EV models; however, my vehicle is not included in those recalls. Despite this, my vehicle is experiencing the same or a very similar issue. The problem has occurred multiple times from 2023-now and does not appear to be related to specific weather, lighting, or driving conditions. This defect poses a serious safety risk and should be investigated for potential inclusion in a broader recall.

I believe the issue is related to something connected to the AC system or a component underneath the hood. The exact part that malfunctioned has not been confirmed. The vehicle is available for inspection upon request. My safety and the safety of others were put at risk because some kind of leak or fumes were being sent into the car through the AC vents, causing myself and others in the vehicle to feel sick. I have taken the car to 3 Kia Dealerships. All of which have been extremely dishonest (have tons of proof) and say they cannot verify problem. I took it to an outside independent shop and they verified it instantly and wrote a very detailed invoice about the problem. They couldnt pin point where it was coming from though. The vehicle has only been inspected by the 3 Kia Dealerships and the independant shop Brake Busters I purchased the car in November of 2025 and had no problems until February 22nd 2026. No warnihg lights or messages came on prior. The symtoms that started were Nausea, Headaches, light headedness, vision blurry, and almost caused me to pass out at wheel several times.

I am filing a complaint regarding my 2023 Kia Niro and Safety Recall SC332. The recall involves a damaged floor wiring assembly that may prevent proper airbag and seat belt deployment, creating a serious safety risk. I scheduled and brought my vehicle to Cowboy Kia, Conroe on Feb 2,2026 specifically to have this recall repaired, but the dealership did not complete the recall service and returned the vehicle without fixing the issue or providing a clear explanation. This is a manufacturer-issued safety recall and should be addressed promptly at no cost. I am requesting immediate repair and an explanation for the failure to perform the recall work.

This car was purchased certified pre-owned from a Kia Dealership with 46,227 miles in October 2024. Within a month (Nov 2024), the electrical system would die overnight and we would require a jump start. This seemed to align with colder temperatures. After the first or second jump start, a headlight blew out. We replaced it. Then a tail light blew out and we replaced that one too. It seemed that there must be a connection between the electrical failure and the headlights / tail lights burning out. We took it in for a software update to see if that solved it, we also had them check the hybrid battery and the 12V battery. No other issues were detected. Eventually the problem just stopped happening. Now in Nov 2025, a year later, the problem has returned. The car's electrical system dies overnight and we have to jump start the car. And another tail light / turn signal has burned out. This time, we called a dealership to ask about any recalls or pending software updates and they said there was nothing showing in their system. We are now driving without a turn signal, which is a significant safety hazard. We will have to go back and replace the tail light / turn signal bulb. But what about the situation recurring? How do we get the car to stop 'dying' overnight in cold weather?

On November 3, 2025 I had an accident/event in my KIA Niro. At 2:20 I had been sitting in my car with the engine running and the gear was in (P) park. I was on an incline. When I saw the child I was babysitting ‘s bus arrived, hopped out of the car (it was still running) and walked behind the car, and stood waiting for him. I told him to hold on and we would go inside after I grabbed my phone and turned the car off. I opened my drivers side door to grab my phone, when the car started moving very rapidly backwards. I made every effort get control of the car but I was unable to, as I was hanging half in half out of the car. I collided with a Toyota truck, and damaged the passenger side rear bumper and lights and the side panel on the passenger side. It all happened immediately after I opened the driver side door. By the grace of God my charge and myself were not hurt, as we were standing directly behind the car moments before I went to turn off my engine and get my phone.

Forward collision system fully activated while driving eastbound in the fast lane on [XXX] . The sun was behind me. No glare. No cars or objects were in front of me or next to me. The dashboard started flashing and warning sounds activated and the car slammed on the brakes itself. The seatbelt locked up and left me bruised. Miraculously, the cars behind me avoided crashing into me while I accelerated out of it. I could have been killed. Dealership minimized my concerns. I don’t want to drive this car ever again unless someone can make sure it doesn’t happen again. This safety feature malfunctioning is a death trap.

I'm writing to express my disappointment and frustration with my recent car purchase. The salesperson's failure to clearly explain the contract has left me with unexpected expenses and a higher payment than anticipated. Furthermore, the car's persistent malfunctions have caused me significant stress and anxiety. The manager told me he was not inclined to help me because he did not like my survey answers so he wouldn't help me like any other customer and I made sure he clarified this . The first day I had it at 40 miles I tried to take it back because I could not get the car to get out of traffic it would not go in any gear it just wouldn't Now, thr R flashes red, the backup camera stays on while driving forward for a while, zero rpms when your going 75, then so fast you can't see #s, window fluid comes right back in your face, something new all the time. Went hunting and had to back down a small hill and get a running start to make it. It's a brand new car. Should not be having problems. Despite my efforts to address these issues, the dealer's lack of cooperation, and Kia Customer Care, have only added to my distress. I just get passed from one person to the next. I ask to speak to a certain person and they won't let me or look into my notes. They told me they were kia property and i could not. This car is going to get me killed or badly hurt. I hope that you will take my complaints seriously and take immediate action to rectify this situation. Car will not go into gear after backing up go to put it in drive. Nothing. Stuck in traffic for 10 minutes. I took the car back to them within 36 hours the car had 40 miles on it I told them it was a brand new car and this should not be happening already and I asked if I could just get my truck back which I knew was dependable. They refused I took it back two more times they never asked to get it looked at they had a kid the first time get in my car with me and drive from one side of the building to the next so

I was turning into a parking spot when my brakes suddenly felt loose, as if they had lost hydraulic pressure, and my vehicle accelerated into a wall. I had my vehicle serviced 3 weeks ago, and my brakes were fine. The day before the incident, I was coming to a stop, and the car was lurching forward as I was trying to stop. This isn't the first time the issue has occurred, and I had previously mentioned it to the dealership, but they found nothing upon checking. I was going to take it into the dealership, but I got into the accident.
