2020 Kia Niro Electric

I had my oil changed in Dec. 2025. I drove 1000+ miles w/no issue. Engine suddenly seized w/no engine light warning. Oil dumped all at once. Kia refuses to cover under warranty. THIS HAPPENED TO MY CAR: NTSA announced it had launched an investigation into Hyundai Motor Company and Kia Motor Company for problems with their oil pans and oil drain plugs... consumers have filed complaints their engine’s oil drain plug falls out, causing all the oil to drain out of their engine while driving. In multiple tests the oil drain plug was tightened according to factory torque specifications and the tightening was well documented. Yet, testing shows in multiple cases that while driving, the oil drain plug falls within a few thousand miles after the service. In those cases, the crankcase drained completely. The Hyundai and Kia drain plug falls out due to inferior oil pan material and the drain plug gasket. The testing and investigations appear to show that the oil drain plans are made with THIN METAL AND THE DRAIN PLUG MOUNTING IS POORLY REINFORCED. In addition, the oil pan is coated with a thick paint coating the bonds the gasket to the pan, so the gasket does not come off when the drain plug is removed. That gasket issue alone is not why the oil drain plug falls out, but it is a factor in the chain of events. The oil pan is the biggest problem Apparently, the thin metal, along with engine vibrations and expansion/contraction tend to loosen the drain plug without any other intervention. NHTSA is investigating this as a factory defect... The problem is two-fold. First, even if the repair shop properly torques the drain plug, the oil drain plug falls out on its own. The customer then blames the shop for shoddy workmanship. Second, Hyundai and Kia dealers are telling customers that servicing their vehicle at an aftermarket shop automatically voids their factory warranty. This is totally false & actually illegal under the terms of the Magnuson-Moss Warranty Act.

I own a 2020 Kia Niro PHEV. In October 2024, my dealership performed Technical Service Bulletin SA512 on my vehicle addressing the inverter coolant system. I was not informed at that time that the issue was likely to recur or that periodic maintenance would be required. In March 2026, the inverter coolant warning light returned. I brought the vehicle back to the dealership, where I was told the coolant had crystallized. The dealer confirmed this is a known recurring issue with this vehicle and stated it would need to be flushed approximately every two years since we drive relatively low miles per year (despite driving every day). I was not warned of this at any point. Furthermore, many owners likely drive it short distances every day since it is a plug-in electric vehicle. Kia denied goodwill coverage and I paid out of pocket for the repair. When I contacted Kia Customer Care, representatives gave conflicting information. One confirmed SA512 was performed as a service campaign, another stated it was only a TSB and declined coverage since my car is out of warranty (even though the warranty should still cover the battery and this is an electrical issue). A total case specialist I was assigned to said she would talk to the dealer and call me back but never did. The inverter cooling system is safety-relevant as it prevents the battery from overheating. The problem was confirmed and repaired by the dealership. The component is no longer available for inspection as the repair has been completed. Kia's issuance of SA512 suggests this is a known design issue affecting multiple owners of this model, and they informed the dealership that they could not cover the cost because if they did so, they would have to cover everyone with the same problem (again implying that the issue is quite widespread.)

Engine Seized at 79,000 miles on Kia Niro Hybrid on 3/8/2025. Oil was changed at 78,225 miles on 12/16/2025. No issues with vehicle until approx. 1,000 miles later and just a month and a half later when car suddenly lost power on a highway forcing me to try to safely and quickly navigate off the road. This could have caused risk to my life and other lives. The car could not be restarted. Kia said the drain plug was not screwed on and is refusing to honor warranty despite no issues with the oil change. Notably, in October 2022, the National Highway Traffic Safety Administration (NHTSA) announced it had launched an investigation into Hyundai Motor Company and Kia Motor Company for problems with their oil pans and oil drain plugs. Specifically, consumers and aftermarket service facilities have filed complaints their engine’s oil drain plug falls out, causing all the oil to drain out of their engine while driving. In multiple tests the oil drain plug was tightened according to factory torque specifications and the tightening was well documented. Yet, testing shows in multiple cases that while driving, the oil drain plug falls within a few thousand miles after the service. In those cases, the crankcase drained completely. [XXX] This issue should be investigated for potential recall to keep drivers, passengers safe on our highways.

There were no symptoms prior to the warning message and warning symbol on the dash. Warning message was "Check EV System". I took my car to the dealer immediately. The dealer has had my car for 3 1/2 months, since Sept 12, 2025. Now the field tech from Kia, on 12/22/25, says that the Electric Power Control Unit (EPCU) needs to be replaced. This could have cause the vehicle to stop in the middle of traffic and cause an accident.

There is a silver strip that runs horizontally along the middle of the dashboard from one side to the other. It’s made out of a very reflective material. During the midday hours, it brightly shines the sun directly into the driver’s and passenger’s eyes—it’s very blinding!–and makes it difficult and unsafe to drive. I can’t even begin to think about teaching our teenage son how to drive in this car because of this safety issue.

What component or system failed or malfunctioned, and is it available for inspection upon request? The component that failed was the Hydraulic Clutch Actuator, which is part of the hybrid transmission system. This component was already replaced in May 2024 under recall SC276, but it failed again. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? The failure significantly affects the vehicle’s drivability. The most noticeable issue is a loud, explosive-like sound during operation and a slipping sensation, especially when braking at low speeds on city streets. The vehicle feels unstable and difficult to control during these episodes. This creates a serious safety risk for me and for others on the road. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, it was inspected by a Kia dealership authorized by the manufacturer as part of recall SC276 in Colorado. It was later inspected again in February by Kia Serramonte in California for the same issue, but the problem still persists. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, there are currently no warning lights illuminated. However, the vehicle shows abnormal behavior such as jerking, loss of power, and a noise similar to an explosion. These symptoms first appeared before the recall in 2024, and then reappeared in August 2024, just a few months after the repair until now. Due to financial limitations, I was only able to take the vehicle in for service in November 2024, and finally left it at the dealership in February 2025. The so-called “repair” lasted two months, but the dealership refused to take responsibility. I had to pay $3,188 out of pocket, and even after that, nothing was fixed — the vehicle remains defective.

2020 Kia Niro was driving fine until one day while driving down the highway at highway speeds (65-70 mph), the car began to lose power and as we switched lanes to get to the side of the highway, the car began to smoke and caught on fire. Our safety was at risk due to the car catching on fire. The problem is unable to be reproduced as the car is a total loss. Vehicle was inspected by police at the scene. There were no warning lights, and the vehicle had been in working condition prior to the incident. The vehicle had a recall that was fixed at our local Kia dealership as soon as a solution was indicated, and the part was located.

About 7 months ago, "Refill Inverter Coolant" warning came up. Since then, I've scheduled service appoitment wtih Van Nuys Kia dealership 5 times to resolve this issue, but even after recent appoitment 2 weeks ago, this warning is still came up on my dashboard. Every time I start the car, the persistent refill inverter coolant light comes on. I believe I am experiencing this issue because KIA and their dealership where I bought my car doesn't want take ownership of this issue and resolve it. I am deeply concerned about my safety and the safety of my children when I drive my Kia vehicle.

My key fob works perfectly fine. I came out from work and my car was dead, I pressed my key fob to unlock and nothing happened. I tried the key attached to the key fob and it’s strange because it doesn’t even fit to open the door. It was so hot outside because I’m in Texas and when I called KIA roadside assistance an hour passed by and they still hadn’t arrived. I could’ve had a heat injury, but I was able to hide under a tree for some shade. This is the second time my car just dies and doesn’t turn on without having to get help from roadside assistance. I took it to the dealership and they did a diagnostic on my car. They said nothing is wrong with it. This is crazy, it’s making KIA look bad. I attached the service copy of the diagnostic test. They didn’t have extra vehicles to rent so I had to take Lyft to work. They were kind enough to drop me off home, but I still had to pay to get to work.

Faulty EPCU and circuit board damaged from coolant leak, as described by Kia technician. Other components have been affected. Estimated $3,000 in parts left to replace. Total repair cost is looking to exceed $13,000. On last failure of car, I was driving as the Electical Vehicle Systems error occurred and the car went into neutral and when it slowed down, went into Park. Car would start and drive 10-15 feet before becoming inoperable again. Dealership says they fixed by adding coolant and they couldn't replicate the error. It took me 200 ft of driving to do it. I turned on the AC and the error happened. Could have been coincidental. Kia has declined/refused repairs because serious fault happened at 60,800 miles and they say its out of warranty. Issue had been going on for about 30,000 miles at that point with no resolution ever being reached. Car has been throwing errors and codes and repeated attempts to have Kia check my car for the recall that had been issued were ignored and i was told the recall wasnt the issue. April 29, 2023 was the first time I contacted Kia service about the Low Inverter Coolant message I was getting. Kia insisted that coolant just needed to be flushed. Coolant Issue persisted. They bled and flushed the system and put new coolant in. Issue peristed. Car was taken to dealership at least 3 or 4 times. On one occasion, technician informed me that if the coolant message goes away when you turn the car off and it doesn't constantly flash, there's no urgent issue. He was apparently misinformed. I have now had the exact thing happen to my car that the recall was meant to prevent. My car was produced in 8/20 so within recall time-frame. My car should be recalled and Kia should be made to rectify the situation. All repair documents and estimates are included in my submission.

My vehicle was the victim of attempted theft and reported to City of Cincinnati police 8/11/23. It then underwent repairs and delays before it was returned to me on 9/22/23. The left side rear door is basically detached from the system, causing the alarm to go off or not even work. The back seat lock is completely malfunctional, and there is glass remaining inside the car. I was informed by two separate Kia locations that they would contact me about repairs. On 9/29, notice attached here, I was informed that when a remedy is available, they will repair and cover the costs. No one has contacted me, and I have called multiple times over the last several months, including leaving voicemails, asking for any updates. I have phone logs I can provide as well.

Drive unit defect in EV motor/reduction gear. These vehicles have a manufacturing defect that causes a percentage of them to experience a loud noise while under acceleration, loudest at around 30mph. It is described as a "card in spokes", "motor rumble", "wheel of fortune", "clicking/tapping" sound. There is a TSB that Kia has released for this issue, ELE234, but Kia continually denies and obstructs owners from getting their vehicles repaired under warranty. It typically begins quietly at around 20-30k miles, gradually getting louder. Currently at 68k, Kia continues to deny repairs. It has been inspected and diagnosed several times by a Kia dealership, acknowledging the defect referenced in their own TSB, but Kia will not authorize the repair.

-Abnormal Reduction Gear and/or EV motor Rumble noise as identified in KIA TSB-234. The car is available for inspection. -Car not working properly/increasing the risk of stall or breakdown while driving and therefore increasing the risk of collision/accident. There is a loss of power and increased revolution noise from the reduction gear/EV motor increasing the incidence of vehicle failure during operation and accident, therefore increasing the incidence of property and bodily injury/damage due to known issues by KIA currently being serviced only under TSB and not as a recall. -This problem was confirmed by the dealer technician. The technician also identified that a TSB exists for the identified issue. Per technician same issue has been previously serviced by the dealership for other Niro EV customers when under 100K (warranty period). Per the technician, this problem occurred outside of the 100K and would require authorization from KIA corporate. Kia customer service was contacted and was unwilling to resolve the issue. -Yes a test drive was performed with the technician who was knowledgeable about the issue and the TSB who immediately identified the issue as the one identified in TSB-234 and informed that some vehicles in the past have been serviced for the exact same issue but require KIA Motors authorization for service outside of 100K. KIA is unwilling to provide authorization. -No prior warning signs/warning lamps, Issues started happening after 100K. The dealer was notified at the time of service of another recall on the current vehicle. No resolution was provided for the safety issue being experienced.

My Niro has been having issues with sputtering, jerking, chugging, and feeling like it’s about to stall. Sometimes it happens right when I start the car and sometimes it happens while I am driving. The check engine light just started coming on yesterday. I believe the transmission is faulty and have spoken to or taken it to the dealer with this same issue multiple times as it is covered under warranty. They keep telling me that’s just how the car drives but in the 8 cars I’ve owned in my life, I have never had a car that behaves this way before. An internet search of “Kia niro transmission problems” proves that this is a common and known issue with this car that Kia is doing nothing to resolve. I have a daily 20 mile commute to work and feel incredibly unsafe driving my car and letting my teenage daughter drive it.

Driving in my 2020 Kia Niro EV EX in the right lane of a 2-lane northbound highway at 3PM on a weekday, clear-weather, I changed lanes into the left lane when all of the sudden the Lane Keeping Assist malfunctioned and startlingly and abruptly jerked me across the double yellow lines into oncoming southbound traffic. I tried to steer the car back into the northbound lanes but the steering wheel was frozen. The malfunctioning Lane Keeping Assist seemed to have completely taken control of the steering wheel. An oncoming southbound car hit me colliding with my front passenger hood, panel and front passenger wheel. Upon impact, my dashboard lit up with warning messages, as the collision sent my car sailing back into the northbound side of the highway crashing perpendicularly into the highway perimeter chainlink fence and parking post. My airbags did NOT deploy! That is 100% airbag failure in a front wheel collision in a front-wheel drive vehicle. Police report taken at site of the incident. My insurance was notified. Insurance advised me to report these mechanical malfunctions to the Kia dealership. I reported to Kia Van Nuys dealership who set up service diagnostics in the dealership Service center. However, Kia Van Nuys Service refused to diagnose the car telling me to "take the car to a body shop" because they could not diagnose the mechanical/technical issue before body damage was repaired.

The Adaptive Cruise Control System is not working. It is available for inspection upon request. The cruise control system does not reset, but rather retains the last set point. When I start the car and touch the accelerator, the car assumes the last set speed setting. In my case that is 60mph. It does not matter what I do, the car accelerates to 60mph. I can "cancel" the setting", tap on the brakes, or try to reset the system to a different speed. I am trying to get an appointment with the dealer for his evaluation. There have been no accidents on my part, but it is very scary that the car just takes off. there were no warnings, lamps, or messages on any of the car consoles. This is a a significant failure, potentially life threatening.

THE SERVICE ENGINE VALVE WITH "CHECK ACTIVE AIR FLAP SYSTEM" ERROR MESSAGE IS DISPLAYED. THE DIAGNOSTIC ERROR THAT COMES UP IS AAF - P059F. ACCORDING TO THE DEALER AIR COMPRESSION TEST WERE COMPLETED AND PROPERLY FUNCTIONING. I HAVE SUBMITTED 3 PICTURES WITH THE SAME ERROR MESSAGE CODE TO THE DEALER AND THEY STATE NOT ALL SAVED IN THE CAR'S ECM. THE LIGHTS CAME ON WHEN STARTING AS WELL AS WHILE DRIVING. NOTICED THAT THE CAR TAKES LONGER TO CHANGE GEARS OR GO INTO EV MODE.
