POWER TRAIN, ELECTRICAL SYSTEM, ENGINE
On XXX, After I attempted to plug my car into my home charging outlet at 240V, less than 20 minutes later I received an alert that my battery was at 0%. After unplugging the car, waiting for 30 minutes and plugging it back into the out, my car was unable to see the charging outlet or the 40A cable plugged into the port. Unplugged car again and after talking to remote mechanic, came to decision to take car to AAA repair shop for troubleshooting. Once at the AAA repair shop in [XXX], was advised to take my car to a Kia dealership, as a module was nonfunctional. Brought car to Beyer Kia in [XXX], who held onto my car for two months before making a diagnosis that my car was struck by lightning via a Field Technical Engineer, though the DTC codes stated otherwise: C180287, C161487, C16b487, C161487, C161487, C182D00. All codes noted are internal Controller Area Network Bus Communication Timeouts between internal modules, not power surge or electrical strike. C161487 - registered three times: Internal network timed out because VCU abruptly went offline or lost power. With it registering 3 times confirms ongoing hardware/power supply struggle inside car's computers, not external bolt of lightning. C16B487 - Another subsystem critical timeout error, unable to communicate with VCU. C180287 - Internal stability/chassis lost data connection over vehicle's internal network. C181D00 - Network fault indicating control module voltage dropped below required operating threshold to maintain communication. Kia is trying to claim an external surge (lightning) caused this. However, if a massive high-voltage lightning surge had entered the vehicle through the charging port, it would have permanently fried the OBC (Onboard Charger) or the ICCU (Integrated Charging Control Unit). This would immediately trigger high-voltage hardware failure "P-codes" (Powertrain). INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ELECTRICAL SYSTEM, ENGINE, FUEL/PROPULSION SYSTEM
My 2019 Kia Niro EV, with approximately 75,000 miles, continuously displays a “Refill inverter coolant” warning. While driving, the vehicle intermittently displays the turtle-shaped reduced-power warning and experiences a significant loss of acceleration. The vehicle does not respond normally to accelerator input. The condition sometimes clears after a period of driving, but when traveling uphill, the warning and reduced acceleration persist. This creates a serious safety concern because the vehicle may be unable to maintain speed or accelerate sufficiently on hills or when merging into traffic. The vehicle has been at an authorized Kia dealership for approximately seven days. The dealership has not yet identified the cause and has reportedly contacted Kia corporate technical support. The dealer has also indicated that another vehicle has presented with a similar issue. I am requesting an investigation into the potential coolant-circulation or thermal-management defect and its relationship to unexpected propulsion-power reduction.

ELECTRICAL SYSTEM
I am filing this complaint regarding my 2020 Kia Niro EV because of recurring inverter coolant warnings, a coolant restriction documented by a Kia dealership, and a subsequent repair estimate exceeding $12,000 that includes the Electric Power Control Unit (EPCU). Vehicle information Year/Make/Model: 2020 Kia Niro EV VIN: [XXX] Kia Customer Care Case: XXX Kia Techline Case: XXX After purchasing this used vehicle, I experienced a recurring “Refill Inverter Coolant” warning. On XXX AutoStream Reisterstown performed an inverter coolant fluid exchange. I paid $376.41 for this service. The warning returned, and I subsequently took the vehicle to Buchanan Kia. On XXX the Kia dealership documented the following in its repair order: “Coolant is congealed and is restricting cooling system causing system to think coolant level is low.” The dealership flushed and bled the cooling system, and its documentation stated that no codes were found. However, the warning returned within days. The vehicle then remained at the dealership for further evaluation. Kia subsequently prepared a repair estimate totaling $12,030.52. The estimate includes the EPCU assembly, part number 36601-0E190, as well as the onboard charger and multiple cooling-system components. I am concerned about the cause of the coolant restriction, the recurrence of the warning after service, and whether the EPCU condition in my vehicle is related to Safety Recall SC258. I have not received a definitive written explanation establishing the cause of the failure or confirming the applicable recall coverage. My vehicle has been unavailable to me for an extended period, and despite repeated contacts with Kia Customer Care, I have not received a definitive resolution. I respectfully request that NHTSA review this complaint for a potential vehicle safety defect, including any relationship between the reported coolant condition and the EPCU assembly identified in the repair INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FUEL/PROPULSION SYSTEM, POWER TRAIN, SEAT BELTS
I purchased this used 2022 Kia Niro EV on August 19, 2023, with approximately 3,042 miles. On December 22, 2023, at 24,086 miles, a Kia of Valencia service record documented a kicking/knocking sensation when releasing the brake. The cause was not identified. On August 22, 2024, another service record documented a rear seat belt retraction concern. I cannot confirm whether these earlier problems share the same cause as the later motor issue. On March 31, 2026, at approximately 139,071 miles, Kia of Valencia confirmed a rattling noise from the gear driver motor and recommended replacement. The estimated repair cost was approximately $4,800. I paid a $250 diagnostic fee but could not afford the repair. I contacted Kia America to request goodwill assistance, but the motor was not replaced. On September 9, 2026, while driving on a freeway in heavy traffic, the vehicle repeatedly stopped and moved again, accompanied by extremely loud knocking, rattling, and banging. The vehicle shook, and no warning lights or messages appeared beforehand. I carefully exited the freeway and stopped the vehicle. After bringing it home, I noticed liquid underneath, but could not determine whether it was related to the incident or normal air-conditioning condensation. I have video recordings and supporting service records. I am concerned that this unresolved mechanical problem poses a serious crash risk, especially in freeway traffic. I request that NHTSA investigate this potential safety defect and review the documented rear seat belt concern.

SERVICE BRAKES, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
This is a supplemental complaint to NHTSA Complaint #11744598 and #11749340. Multiple 2020 Kia Niro Hybrid and Plug‑In Hybrid vehicles are exhibiting identical Electronic Parking Brake (EPB) failures. I have personally encountered other Niro owners reporting the same intermittent EPB/ABS/ESC warnings. A Kia service coordinator confirmed another 2020 Niro currently in their shop with the same issue. In that case, Kia declined warranty coverage because the owner is the second owner, despite the failure involving safety‑critical brake system components. These repeated occurrences indicate a broader pattern of EPB system malfunction across 2020 Niro Hybrid and PHEV models.

ENGINE, VEHICLE SPEED CONTROL, POWER TRAIN
I have experienced two incidents of sudden, severely reduced propulsion while driving my 2024 Kia Niro Hybrid. The incidents occurred several weeks apart. During both incidents, pressing the accelerator did not produce normal acceleration. The vehicle continued moving with very limited propulsion, but the gasoline engine remained at 0 RPM and did not engage when additional power was requested. There were no warning lights, error messages, or other indications of a malfunction on the dashboard. During both incidents, I shifted to Neutral and back to Drive while safely coasting, but this did not correct the problem. After coming to a safe stop, placing the vehicle in Park, turning it completely off, and restarting it, normal acceleration and gasoline-engine operation immediately returned. After the first incident, the vehicle was scanned for diagnostic trouble codes and none were found. This failure creates a serious safety concern because the vehicle may unexpectedly be unable to accelerate when merging, crossing traffic, or otherwise attempting to avoid a collision.

ELECTRICAL SYSTEM:12V/24V/48V BATTERY
September 18th I had to jump the battery from the 12 volt switch at the drivers side dash. Going to the dealership where I had bought it on August 27th I noticed smoke rolling out from behind the car. I exited off the highway 40 and checked the oil it was clean and full. Water level in radiator was also fine. It smoked several times during the trip but the service department at Parkside Kia was no longer opened so I returned the next morning when I got there they service department technician could not find anything wrong with the battery and he never seen any smoke. Now, I will take it to another Kia dealership in my area because I do not feel side driving it on the highway on a long trip anymore.

POWER TRAIN
On August 22nd, I was driving from the grocery story to my house (5 miles away) when the transmission started failing only going on 2nd gear and the check engine light came on, when I got home, I called my mechanic and he connected his code reader to my card and the error code is P090B$07E9 Clutch "B" actuator control circuit performance error, he told me that Kia motors had an open recall for the clutch actuator, I called the Kia dealer to make an appointment for August 26th I told them the issue with my car and they told me they will check that error, it took two weeks for them to return my car and they told me that they replaced only the fuse for the Recall SC275 / NHTSA 23V534000 and they told me that I needed a new transmission and the price to replace it was $6,000.00 plus tax, I told them that the issue it was because the clutch actuator, they said no, so I took my car home, and took it for a second opinion with an independent service center, after the inspection they told me that the transmission failed and it was stuck on the 2nd gear and it was better to replace the transmission, I went back to the Kia dealer ship and demand a formal diagnostic report explicitly stating whether the Hydraulic Clutch Actuator (HCA) has leaked fluid onto the printed circuit board. But they refused to re-inspect the car, I told them if they can open a goodwill claim with Kia corporation and they said no, I called Kia corporation and explained the situation, after 30 minutes on the call with a service representative they told me that they goodwill claim was denied because I had no proof the issues was related to the Clutch Actuator, I told them I have owned the car for almost 3 years and they never send me letters of the recalls related to my car and I didn't know they have several recalls on this car that was never fixed. I am just frustrated that my car is broken and I need to pay over $6,000.00 for a new transmission.

On XXX, at approximately 11:30 a.m., a friend and I were driving on XXX near [XXX], when I noticed smoke coming from the engine compartment. As I pulled over to the side of the road, a warning light appeared on the dashboard. Once stopped, I saw flames coming from the engine compartment. We immediately got out of the car, retrieved our dogs from the back seat, and ran away from the burning car. Another motorist who had witnessed the flames pulled over behind us. Because our cell phones were still inside the car, we used his phone to call [XXX]. The Tennessee Highway Patrol and the Fire Department responded to the scene. The car was completely destroyed by the fire and was declared a total loss. We were unable to retrieve anything from the car. There was no collision with another car or object. The car is now located at [XXX]. Telephone [XXX]. On XXX KIA Ourisman of [XXX] had installed a rebuilt engine, as according to them, the original engine had “thrown a rod.” An insurance claim has been filed with GEICO. Complaints have been filed with KIA of [XXX] and [XXX] KIA of [XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The dealership is falsely reporting to Kia Corporate and the NHTSA that Recall SC276 is 'completed' by only replacing a fuse. They are refusing to replace the actively leaking, fire-hazardous Hydraulic Clutch Actuator unless I pay an out-of-pocket diagnostic fee. They are violating federal recall safety mandates by trying to release a vehicle with an active, un-repaired recall leak.

My 2018 Kia Niro had the Hydraulic Clutch Actuator (HCA) replacement in 2024 due to a recall. About two years later, it failed again causing the call to completely stop working creating safety issues for me. The car was towed to the dealership but Kia refused to pay for the fix. I eventually paid for the fix and requested a reimbursement since my vehicle is directly impacted by Safety Recall Campaign SC276 (NHTSA Campaign 23V534000) due to a critical design defect causing fluid leaks and electrical fire hazards. Kia never responded after initial request for escalation on August 4th, then August 14th, then August 21st and finally a voicemail on September 1st. Under federal safety regulations managed by the National Highway Traffic Safety Administration (NHTSA), a manufacturer's statutory obligation to permanently resolve a safety-related defect does not expire if a previous, interim campaign remedy fails. The secondary failure at 44,723 miles demonstrates that the initial remedy failed to permanently safeguard the vehicle against the safety hazard. Per Kia's official recall notification, owners who incur expenses to remedy this specific issue have the opportunity to obtain complete reimbursement. Thank you for your prompt attention to restoring safety compliance to my vehicle.

POWER TRAIN, ELECTRICAL SYSTEM
The vehicle's hydraulic clutch actuator (HCA) has failed and is actively leaking fluid onto the printed circuit board (PCB), creating an immediate electrical short and engine bay fire hazard. This failure is identical to the defect detailed in Safety Recall SC276 (NHTSA Campaign 23V534). As indicated by a search of my VIN, the vehicle was brought in by us previously when we learned there was a recall, and the recall was officially marked "completed" in the NHTSA database. However, the dealership at the time claimed the vehicle was not affected by the recall, stating there was nothing wrong. They simply performed the minor step of changing a fuse to mark it as completed but did not provide an actual remedy or replacement for the actuator assembly itself. The original manufacturing defect has now actively manifested, causing a severe, active fire risk. The vehicle is currently grounded at an authorized Kia dealership. The dealership and Kia Corporate have acknowledged the dangerous defect by offering a partial goodwill gesture to cover the replacement parts. However, they are refusing to cover the $750+ labor charge required to safely replace the fire-prone assembly. Furthermore, the dealership has held my vehicle for over a month, taking a full month just to communicate this partial remedy. I am filing this complaint because a previously executed safety recall has catastrophically failed, and the manufacturer is refusing to completely remediate an active, federally documented fire hazard free of charge.

I park the car, lock it and then later on can’t open it. I use the emergency key to enter it but then can’t start it even with a new battery in the key fob. It happened twice. It is an issue that needs to be fixed as soon as possible because in case of emergency you’re stuck outside your car and can’t use it to escape a danger or respond to an emergency. You’re a sitting duck in the open, going nowhere.

SERVICE BRAKES, ELECTRICAL SYSTEM
2019 Kia Niro. While driving normally on the street, the driver attempted to brake & the brakes would not respond. This is a very scary situation and Kia needs to handle immediately!! The message "Stop the Vehicle and Check Regenerative Brakes" was displayed. Thankfully the driver was able to come to a stop without crashing but if this was during heavy traffic time it definitely would've resulted in a crash. Could be even that much worse on the freeway, especially in Los Angeles. The vehicle was towed to the drivers home. After checking again, the vehicle was in limp mode & would not go over 15mph. The driver was able to get it to a Kia shop to be checked & they quoted a $9,000 repair!! This is horrible that Kia is allowing this issue to go on!!!

My 2023 Kia Niro Hybrid has a recurring intermittent electrical defect. Warnings appear together: Check Hybrid System, Check Engine, Forward Collision, Rear Cross-Traffic, Lane Keeping, Driver Attention, ESC, Brake, Auto Hold. They appear and persist while driving, during which stability control, automatic emergency braking, lane keeping, and related safety assists are disabled. Once, the vehicle would not start and was temporarily disabled, recovering after several minutes. This creates risk from loss of all electronic safety assists in traffic and from the vehicle failing to start when needed. Stored codes show lost CAN communication among multiple modules: U0101, C1611, C1693, U0111, U0164, U0293, U042B, U1341. Confirmed by two Kia dealerships over five warranty visits. V1–2 (Coughlin Kia, Dublin OH): software updates; warnings returned. V3 (Ricart Kia, Columbus OH): inspected, released OK; warnings returned. V4 (Ricart): Kia Techline case [XXX] opened; CAN signal confirmed out of spec at a passenger kick panel connector; dash harness replaced per Techline under warranty (~$2,800). V5 (current): same warnings returned within days, confirmed by the dealership; vehicle is in the dealer's possession for continued diagnosis and available for inspection. Warnings first appeared June 2026 at ~58,500 miles, recurring since. Current mileage ~59,700. No crash or injury. Kia Consumer Affairs case open. Note: attached RO [XXX] says no issues found after repair — outdated; warnings returned within days, vehicle back at dealer.

When stopping for a traffic sign or light, the car announces that it is shifting into park and does so. The car then will not shift into drive or reverse and is essentially disabled. Turning off the car completely and turning it back on will not return it to "Ready to Drive" mode. Jump starting the car, provided it is jump started twice, will clear the problem and move the car to "Ready to Drive" mode. The car has been towed to dealers on three occasions with the technicians reporting they cannot reproduce the problem and no codes are being logged. On the third occasion, the dealer replaced the 12-volt battery. The failure occurred on the dealer's lot when I arrived to retrieve my car, but the technician reported that the problem went away and no codes were logged, so I should leave with my car. Subsequent to the battery replacement and including the failure on the dealer's lot, the problem has occurred 6 times in 7 days. Prior to the 12v battery replacement, the problem occurred once every 4 to six weeks. The problem has occurred a total of 9 times between April 25th and August 31st, 2026. This is an extremely dangerous problem as failures occur in traffic and require police assistance to safely tow or jump start the car. Should this failure occur during a left turn or on a highway, the outcome could be catastrophic. The car is available for inspection upon request. There are no warning lamps, messages or other symptoms of the problem prior to the failure other than the announcement that the parking brake is being automatically engaged. I have opened a case with KIA Customer Care.

The contact owns a 2020 Kia Niro. The contact stated that while driving at an undisclosed speed, the coolant system warning light illuminated. The contact stated that after entering the vehicle following a charging session, there was a burning odor coming from the vehicle while the coolant system warning light was illuminated. The contact stated that the 12-volt battery voltage decreased from 12 volts to 2 volts. The vehicle was taken to the dealer several times, and TSB: ELE270 was associated with the issue. The contact was informed that the inverter coolant pipes had failed and needed to be replaced, and that the BSC-1 coolant needed to be replaced with BSC-2 coolant. The vehicle was repaired; however, the failure recurred. The contact stated that the coolant system warning light was illuminated after the vehicle was returned. The contact was concerned that the vehicle posed a fire risk because the vehicle was being charged in the garage at the residence. The manufacturer was made aware of the failure, and a case was opened. The failure mileage was approximately 58,000.
