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.

My kia niro 2018 backup camera takes a few seconds to start up when the vehicle is put in reverse. the time it takes differs from a second to sometimes 5 seconds. I know of accident caused in a McDonalds drive through where someone was backing up but the cam didn't turn on right away and they got in a small accident.

The contact owns a 2018 Kia Niro. The contact stated that while driving at an undisclosed speed, the temperature gauge became elevated, and the vehicle stalled. The message "Check Hybrid System - Turn Engine Off" was displayed. The contact associated the failure with NHTSA Campaign Number: 23V534000 (Power Train). The dealer was contacted and stated that the vehicle was serviced under the recall; however, the vehicle was still inoperable, and additional diagnostic tests were needed. The vehicle was towed to an independent mechanic, and the mechanic discovered that there was no coolant inside the coolant reservoir. The contact attempted to contact the dealer but had not received a reply from the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 158,000.

The vehicle experienced a sudden powertrain failure while driving. A certified Kia dealership diagnostic scan confirmed active Diagnostic Trouble Code (DTC) P17ED (Engine Clutch System) and a physical hydraulic clutch fluid leak around the transmission housing area. These symptoms match the exact criteria of NHTSA Safety Recall 23V534 (Kia Campaign SC276) for the Hydraulic Clutch Actuator (HCA). The manufacturer's defective component leaked fluid, causing direct consequential failure of the internal clutch and transmission assembly. Kia is refusing to remedy this safety campaign failure at 100% zero cost to the consumer, violating federal safety recall mandates by attempting to charge 50% of the repair cost ($3,708.29) under the guise of 'goodwill assistance'.

Year/Make/Model: 2018 Kia Niro Hybrid Mileage at time of incident: approximately 69,000 Component: Hybrid Propulsion System / Powertrain My 2018 Kia Niro Hybrid has experienced five recurring "Hybrid System Failure — Turn Off Engine" errors occurring without warning while the vehicle was being operated. Each occurrence rendered the gas engine ineffective in moving the vehicle, creating an immediate safety hazard. The driver was forced to quickly navigate to safety each time. The vehicle has been brought to the dealership four times for this issue — February 25, May 4, May 15, and May 30, 2025. On May 30 the dealer performed a repair they stated would resolve the problem. The vehicle was returned the same day. On May 31, one day later, the error occurred again. The defect remains unresolved after four service visits. Out-of-pocket towing and rental car costs have been incurred each time. I believe this defect is related to the hydraulic clutch actuator issue covered under Kia recall SC276 and the active class action lawsuit (FeganScott v. Kia/Hyundai). The recall repair has not resolved the problem.

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.

On April 21, 2026, Go Kia Renton performed an oil change on my 2018 Kia Niro Touring (VIN). The car was in perfect condition just two weeks earlier — North Seattle Transmission did a full service on April 6, 2026 at 283,649 miles with no issues noted. Later that night while driving, the red oil light flashed. I pulled over immediately and called AAA. AAA towed the vehicle from Belltown [XXX] ) at 12:11 AM on April 23 to my house then at 9:14 AM towed it straight to Go Kia Renton. The AAA driver found oil leaking all over his tow truck. The car now has a dead battery and is showing Hybrid Control System / Low Voltage DC/DC Converter and Engine Control System codes. This appears to be a sudden engine seizure caused by oil loss shortly after dealer service. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am reporting a safety issue involving my 2018 Kia Niro hybrid related to the Hydraulic Clutch Actuator (HCA), which is currently subject to a recall addressing fire risk. My vehicle has already had the recall remedy performed, which consisted of inspection and installation of a lower-amperage fuse. The dealer confirmed that the actuator is leaking fluid but did not replace it because there was no evidence of PCB contamination, which is the condition required under the recall. However, the vehicle is now experiencing significant drivability issues that create a safety hazard: Intermittent hesitation when accelerating from a stop Failure to properly engage the transmission, especially on inclines Engine revving without corresponding vehicle movement Delayed or inconsistent clutch engagement In one recent instance, the vehicle would not properly engage while attempting to move from a stopped position on an uphill incline, creating a hazardous situation where the vehicle could not reliably move when needed. This condition appears to be caused by loss of hydraulic pressure due to the leaking actuator, even though it has not yet reached the stage of PCB contamination described in the recall. The current recall remedy does not address this failure mode. Instead, it allows a known defective component to remain in service until it reaches a condition that presents a fire risk. In the meantime, the vehicle can experience loss of propulsion under normal driving conditions. I believe this represents a separate safety defect or an incomplete remedy, as loss of propulsion, especially during acceleration from a stop or on an incline, can significantly increase the risk of a crash. I am requesting that NHTSA investigate whether the current recall adequately addresses all safety risks associated with the defective Hydraulic Clutch Actuator, including drivability and loss-of-propulsion conditions that occur prior to PCB contamination.

Ever since the purchase of the car I been bringing this attention to the dealership but they always turn down and avoiding the situation at first electrical issues like turning signals goes in and out window stop rolling up sometimes had to try for hours just rolls up fog light check light headlight and turn signal all together went out in the beginning started to work in and out and now window turn signal front both and one fog light now won't come back and front Air Flap won't operate that's from the few months into the car check light and also in the beginning car transmission always felt rough not gears smoothly change I brought this attention but they always ask change the transmission fluid but it's was a new car felt that but never bothered looking into but over time got worst now it hit you when picking up like gear just stuck and your whole body gets that shock like someone hit you from the back every time and when comes to slow stopping making crying sound. It's like I made the biggest mistake why I decided to buy the new car because I know old cars have problems but this is Brand New I bought shouldn't have problems, and from it's was new always heard the click sound when move from complete stop like go from on red light or from any stop position click hear it from front never worried but was not feeling good why but now all of sudden it's unbearable sound when turning or making u turn loud like anything when acceleration but not in straight drive asked dealership about all the problems I been getting since was a brand new car the answered I got it's now not in the warrenty will cost to check wow what a rip off and when I use to say those problems when was in the warrenty they would say it's not the major issue and yes one time one of the tech specialists I mentioned he you know what he said made me sick we would try something but warrenty is BS it's a piece of *** we never get money easily so this is why they always refuse to take this seriously wow

Driver heated seat shorted out and caused burn to leg. System has not been repaired, will wait to hear from Kia Customer Affairs prior to decision to repair. I was injured by this and have concerns about the safety of the vehicle, will this happen again if a new grid is installed. Kia dealership confirmed that the grid showed high resistivity but also claimed since nothing is melted I couldn't have been burned. The vehicle has only been inspected by the dealership currently. there were and are no indicators, warning lights or messages about the failure available. Kia dealerships claims there no way to tell with the electrical systems.

Just before Hurricane Helene, I brought my 2018 Kia Niro Hybrid to Asheville Kia (NC) after noticing coolant loss and white smoke coming from the exhaust. The dealership charged me $1,400 for a repair involving new gaskets and the EGR cooler. Within a month, the same symptoms returned. I returned to the dealership and explained I believed the original issue had not been resolved. I had done research and found reports of similar problems in other Niro Hybrids. I specifically mentioned the coolant heat exchanger as a possible source, but they dismissed my input and pushed a $3,500 muffler system replacement. I asked for diagnostic proof, and they initially showed a photo of the muffler with no visible leak. Later, they claimed a "small leak" was found during a pressure test — but the symptoms didn’t align. I then took the vehicle to John’s Kwik Lube in Spruce Pine, NC, where they confirmed the coolant heat exchanger was faulty — exactly what I had originally suspected. They repaired it with a simple workaround for under $200, and I’ve had no issues since. The faulty component (coolant heat exchanger) is not available for inspection, but I retained diagnostic records, pressure test results, and screenshots of the dealership’s estimate. I also documented that Kia’s quote system does not allow access to past service quotes, so I had to screenshot everything manually. The only symptoms were coolant loss and white smoke from the tailpipe, beginning shortly before the storm in September 2018, and recurring until the final repair later that year. The problem was confirmed by an independent mechanic, and partially acknowledged (though misdiagnosed) by the Kia dealership. No police or insurance inspection was involved. This situation posed a safety risk due to reduced visibility, potential engine overheating, and exposure to coolant vapors, especially during uphill driving. The issue is known among Kia owners and appears to be a recurring design flaw in the Niro.

SERVICE BRAKES
An alert to "check regenerative brakes" popped up on the dashboard screen. My younger sister who is borrowing our car, told me it now takes her much longer to come to a stop when braking. She's having to brake really early to stop on time but traffic and animals will not always allow for that. From what I am reading online, this is a common issue due to faulty 12v battery or a loose ground from said battery. The only way to fully engaged the conventional brakes (without the regenerative brakes) is to switch the car into neutral and then brake. This is a major safety issue that Kia should address. Maybe they need to address the battery issue, but they definitely should address the fact that you have to shift into neutral to brake properly when the regenerative brakes arent working right. Seems like a common sense plan to have it default to conventional brakes when the others are having issues or at least provide a way to turn off regenerative brakes.
