NHTSA investigations into the 2020 KIA Niro
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.

Pedestrian alert sounds
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles.

Recalls on the 2020 KIA Niro
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.

Kia America, Inc. (Kia) is recalling certain 2017-2022 Niro and 2018-2022 Niro Plug-in Hybrid vehicles. Fluid may leak into the printed circuit board inside the hydraulic clutch actuator, which can result in an engine compartment fire.
Risk: A fire increases the risk of injury.
Canada — Transport Canada
Canada runs its own recall programme, and its campaigns do not
always mirror the American ones.
Recall 20253452,604 units in Canada
Visual System
Issue: On certain vehicles, a problem with the rearview camera could cause the rearview camera image not to display. Canadian regulations require the rearview image to display when the vehicle is reversing. Safety Risk: A rearview camera image that doesn't display could reduce a driver's ability to see behind the vehicle while backing up. This could increase the risk of a crash. Corrective Actions: Kia will notify owners by mail and advise you to take your vehicle to a dealership to replace the rearview camera.
Recall 20250032,191 units in Canada
Brakes
Issue: On certain vehicles, water could enter the integrated electronic brake (IEB) and cause it to corrode. If this happens, the IEB motor could fail and cause reduced braking. Note: This service campaign only affects certain Niro EV models. Safety Risk: Reduced braking can cause extended stopping distances and increase the risk of a crash. Corrective Actions: Kia will notify owners by mail and advise you to take your vehicle to a dealership to inspect the integrated electronic brake. The dealer will apply silicone to the IEB bolt hole or replace the IEB, as necessary.
Recall 2024549647,384 units in Canada
Label
Issue: On certain vehicles, the compliance label may be missing information in French. The words listed on the label for "Tires", "Rims", "Front" and "Rear" appear in English only, when they should be listed as "Tires/Pneus", "Rims/Jantes", "Front/Avant" and "Rear/Arriere". Canadian regulations require this information to be listed on the label in both English and French. Safety Risk: These small errors do not affect vehicle safety. Corrective Actions: This is not a recall. Kia has corrected the compliance label for all new vehicles.
Recall 202342313,037 units in Canada
Powertrain
Issue: On certain vehicles, fluid could leak onto the printed circuit board for the hydraulic clutch actuator (HCA). If this happens, the circuit board could short circuit. Safety Risk: A short circuit could create the risk of an engine compartment fire while driving. Corrective Actions: Kia will notify owners by mail and advise you to take your vehicle to a dealership to inspect the hydraulic clutch actuator (HCA), and replace it if necessary. The technician will also install a new fuse for the HCA to reduce the risk of a fire.
Recall 2022689428 units in Canada
Electrical
Issue: On certain electric vehicles, the electric power control unit (EPCU) may not be sealed correctly. As a result, coolant could leak inside the EPCU and onto the circuit board. If this happens, the vehicle could suddenly lose power to the wheels. Safety Risk: A sudden loss of power to the wheels may increase the risk of a crash. Corrective Action: Kia will notify owners by mail and instruct you to take your vehicle to a dealership to inspect the EPCU for internal coolant leaks. If a leak is detected, the dealer will replace the EPCU.

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.

I first bought the car brand new from the car dealership and the first problem was a check engine light came on when I bought it. I took it to the car dealership and could not find the problem. I bought the car in December 2020. And off and on the check engine light comes and goes. And they could not find the error. Lastly about two weeks before the car caught on fire. It was service for oil change and a catalytic converter replacement. After that while I was driving on the parkway in New Jersey I heard a loud bang in the engine and I pulled over and I saw a fire starting underneath the engine. The whole car is consumed in fire. The fire department came and put it out.

This submission is supplemental information for my prior NHTSA complaint (Complaint #XXX). After filing the original report, I learned additional details from the Kia dealership that serviced my vehicle. The service department stated that they have seen the same electronic parking brake controller and actuator failure on multiple Kia Niro vehicles from model years 2018–2021. They reported that these failures were not covered under warranty for those years, even when the symptoms began during the warranty period. The dealer also explained that Kia made design improvements to the electronic parking brake system in later model years and expanded warranty coverage for the updated EPB assembly and control components. This suggests that Kia was aware of recurring issues with the earlier design, despite no formal recall or service campaign being issued for the affected 2018–2021 vehicles. I am submitting this supplemental information because it indicates a potential pattern of safety‑related failures involving the electronic parking brake system across multiple vehicles and model years. These failures affect the vehicle’s ability to hold position when parked and may interact with braking and stability control systems.”

What's malfunctioning: coolant monitoring system shows low coolant warning when coolant level is observably fine. Problem has been ongoing for over a year. Available for inspection: yes. Safety problem: coolant monitoring is inaccurate, causing alarm when coolant levels are fine and possibly causing no alarm when coolant levels are too low. Problem reproduced: yes, by both dealer and independent service center. Vehicle inspected by manufacturer: yes. They attempted service but their repair only lasted a few months. Symptoms prior to failure: no. The problem is that the warning lights are turning on when they should not be. This matches the symptoms of Kia Technical Service Bulletin SA512, but the manufacturer's fix did not work.

SERVICE BRAKES
The electronic parking brake controller failed after intermittent warnings that began while the vehicle was still under warranty. The parking brake actuator also failed and had to be replaced. The electronic parking brake system is part of the vehicle’s safety system, and the failure caused the parking brake to malfunction unpredictably. The issue did not store persistent diagnostic codes, making it difficult to diagnose earlier. This is a safety concern because it affects the vehicle’s ability to hold position when parked and can interfere with braking and stability control. Because I am not the original owner, Kia refused to perform this as a warranty repair even though the intermittent failures began while the vehicle was under warranty.

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 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.)

ELECTRICAL SYSTEM
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.
