2017 Kia Niro Hybrid subject to Safety Recall SC276 (NHTSA Campaign 23V534) for the Hydraulic Clutch Actuator (HCA). Fluid contamination of the HCA PCB can cause an electrical short and engine compartment fire risk. Official remedy is HCA inspection/replacement as necessary plus a new fuse. Three dealer visits: Shortly after purchase for SC276 recall and routine service. Dealer performed HCA Inspect/Replace, reported no problem codes, and replaced the fuse. After sudden complete loss of propulsion on the freeway at 60-65 mph with a passenger. Engine RPM rose sharply as if in neutral. No accelerator response. Brake system warning lights illuminated. Had to pull over to the shoulder, shut off and restart before it would move. Took to dealer same day. They kept it several days, found no codes, could not duplicate, and released as "good to go." Vehicle later would not move and entered limp mode. Towed to dealer. That morning I replaced spark plugs myself with new NGK Laser Iridium Premium and informed the dealer. HCA fluid reservoir was empty. Dealer diagnosed internal leak in the HCA causing clutch contamination. Photos showed green fluid on undercarriage. Repair estimate exceeds $6900. Same Multi-Point Inspection that diagnosed the internal leak marked fluid leaks and fluids as Passed. Report still recommended spark plug replacement despite being told they were just replaced. Sudden loss of propulsion on public freeway with a passenger present, followed by complete loss of driveability due to internal leak of the same recalled HCA component, created a clear safety risk. Vehicle became undriveable and required towing. Prior "good to go" release left the vehicle on the road with an unresolved issue involving the recalled component.

My 2017 Kia Niro exhibits a dangerous low-speed engine surging hazard matching Safety Recall SC276. An authorized Kia dealership technician inspected the vehicle under RO #6115244 and formally documented 'seeping fluid residue' inside the clutch actuator housing. However, the dealership and Kia Corporate are refusing to honor the recall remedy and have released the car at a $0.00 balance while explicitly stating in writing that the vehicle is 'not safe to drive.' I am requesting federal intervention for safety campaign non-compliance.

The vehicle experienced a dangerous driving failure due to a hydraulic clutch actuator system issue and was towed to Kia Delray. The authorized dealership has officially diagnosed the issue as a "brake/clutch fluid leak" (attached diagnostic estimate), which is exactly the hazardous condition outlined under Safety Recall 23V534 (SC276). However, the dealer refuses to perform the free recall repair remedy, claiming that the recall campaign was technically marked as completed after a previous interim fuse replacement. They are demanding $5,642.21 out-of-pocket and threatening to charge $75/day storage fees starting Monday morning. I am seeking immediate federal regulatory intervention as this vehicle has a well-documented fire and safety hazard that the manufacturer refuses to cure.

The Hydraulic Clutch Actuator (HCA) and the Under Hood Wiring Harness have failed due to internal fluid contamination and corrosion. Yes available for inspection. The vehicle experienced a sudden loss of motive power while driving. Per Safety Recall SC276, this component failure creates an electrical short and internal corrosion that poses a significant fire risk and potential for a sudden stall at high speeds, endangering the driver and other motorists. YES. Rusty Wallace Kia of alcoa confirmed the failure on 04/27/2026. They diagnosed the vehicle with DTCs P17EE and U1010. They provided a repair quote (RO XXX) for $9,431.48 to replace the corroded HCA and harness. YES. The vehicle was inspected by an authorized Kia dealer (Rusty Wallace Kia of alcoa ). They are refusing to perform the Recall SC276 mandated repair, claiming it was "already completed" with a fuse swap in Jan 2024, even though the safety defect has now manifested as a full component failure. Yes. The HEV warning light and Check Engine light appeared. Symptoms include "Check Hybrid System" messages and the vehicle failing to engage the engine clutch. These symptoms appeared recently at approximately 107,000 miles. Then when i checked the car it vanished, no error on dashboard ,so i took the car back and was driving error showed up at 109k miles again They asked to repair the vehicle and the repair is not in my budget and i told them that its the recall related issue and they are denying and saying recall was done and they dont open recall again and I found in the document they provided they just did the fuse replacement not HCA unit and The fuse swap did help with the hca corrosion and its not in drivable state and it becae a fire hazard.

The contact owns a 2017 Kia Niro. The contact stated that while driving approximately 60 MPH, there was smoke coming from the rear of the vehicle. The message, "Turn Off the Vehicle and Stop" was displayed, and the transmission failure warning light was illuminated. The contact pulled over and turned off the vehicle. Once the vehicle was turned off, the smoke dissipated. The vehicle was towed to the dealer, who diagnosed that there were holes in the engine, power steering, and there was an engine oil leak. The engine, transmission, and battery were replaced. However, 2 months later, the contact attempted to start the vehicle; however, the vehicle failed to start. The vehicle was scheduled to be towed to another dealer, Buster Miles Kia (1401 S Quintard Ave, Anniston, AL 36201). The vehicle was not diagnosed or repaired. The manufacturer was informed of the failure, and it was determined that the repair was not covered under warranty or recall. The failure mileage was approximately 50,500.

I previously had major issues and recall 23V534000 fixed on my 2017 Kia Niro. I had issues again and took it to the local Kia dealership in Wichita, KS. They found a leak in a seal causing fluid to leak on to the clutch actuator. The service tech indicated it is related to the recall. I have spoken with Kia customer service escalations on multiple occasions. Originally they stated it was related to the recall. When I spoke when them today, on the phone they said all the parts that are affected are what were changed out previously. When they called back, they changed the story and said it is not related and they would not pay for it to be fixed, even though they previously said it was the exact thing related to the recall. When I emailed and asked for it in writing as to why it was denied, she changed the reasoning. It was nothing the same that she had told me on the phone. This is a safety issue that should be fixed by the manufacturer and they are refusing to fix it and telling me I have to pay over $5000 to fix it. Completely unacceptable.

When I was driving, a propulsion system warning went off. Then a malfunction in the vehicle’s powertrain/propulsion system lit up on the GPS screen. Shortly afterward, the engine began smoking, and a loud popping sound occurred simultaneously. The vehicle then experienced a sudden loss of propulsion, requiring me to pull over immediately to avoid a hazardous situation. An authorized Kia dealer subsequently diagnosed a blown head gasket with internal coolant intrusion, confirming an internal powertrain failure consistent with propulsion system malfunction, and the vehicle became inoperable. The vehicle was inspected in October and the loss-of-propulsion failure occurred in December.

I am experiencing engine issues with my 2017 Kia Niro Touring Launch Edition at approximately 111,000 miles, including engine hesitation and lack of acceleration, along with engine code P0011. These symptoms started suddenly and have made highway driving difficult and potentially unsafe, as I was recently in the mountains unable to exceed 35 mph. This appears to be a widespread issue among 2017 Kia Niro owners, with many reporting CVVT (Continuously Variable Valve Timing) or solenoid failures around 100,000 miles shortly after the powertrain warranty expires suggesting a pattern of premature failure. My car was purchased certified preowned and is still within the 10 year timeframe. No official recall currently exists for this issue, but it should be investigated. Despite submitting service requests and making multiple attempts to contact the dealership to have these recalls addressed, I have received little to no follow up. I have not yet had the engine issue officially diagnosed by a Kia dealer due to lack of response but the pattern of failure and symptoms match what others are experiencing. There has been no crash, fire, or injury at this time, but the combination of the existing fire related recalls and the new engine malfunction creates serious concerns for long term safety and reliability.

I received a warning indication that the engine temperature is too hot while driving the vehicle to work. I opened the hood of my vehicle and discovered the vehicle’s coolant reservoir was empty which led me to believe there was a coolant leak. I took the vehicle to be inspected and diagnosed by an independent repair shop (non-dealership) and it was explained that there was in fact a coolant leak and it’s because the exhaust heater exchanger is failing. This is a serious safety concern because if there is a coolant leak the vehicle’s engine can overheat causing further and extensive damage to the engine which could result in a fire. Based on research, there have been other cases where this particular year/model vehicle has had or is experiencing issues with the exhaust heater exchange failing. This faulty system is causing customers who own the same year/model vehicle that I drive to either bypass the exhaust heater exchange all together—which I don’t believe is safe to do—or customers are being made to pay a huge bill just to repair the faulty system. My vehicle only has 73,000 miles and this is something that I should not be experiencing especially since Kia is aware of the fault with the exhaust heater exchange on these particular year/model vehicles. Kia should be recalling these vehicles with the faulty system for diagnosis and repair as this is a major safety concern on the road not only for the driver, but also for other motorists as well.

Hybrid System Failure due to overheating Overheating due to coolant leak into resorvoir My car started having white smoke come from exhaust during driving Took to the repair shop, repaired the coolant reservoir next day, same issue took back to the service tech stated they couldn't find the leak, but the reservoir was empty. Took the car for a second opinion, the service people had my car all day, after picking up, was told by the repairman that it was the engine and KIA is aware of it. Stated he is unable to help and I should take the car to a KIA dealer For weeks the car was still blowing smoke Took the car to KIA of Stamford Had the car for a few hours, tech said coolant leak and I will need to replace the part which is 3000, advised there is a bypass method on the internet for NIRO owners with the same issue online, and I was told they will not do the bypass due to emission laws. Advised my car should be covered under Emissions warranty, and was told it does not cover the part. Advised the service man this should be covered under my 100,000 warranty with KIA, which is what I was sold, and was told this is not the case, and I wasn't covered. Advised KIA I have an extended warranty with WIZ autos where i purchased the car. Spoke to the warranty department and was told it wasn't covered under their warranty either. May 2023 While driving I saw white smoke, my car began to overheat and I tried to pull over, when I pulled over the car would not drive. HYBRID System Malfunction The car has been with Wiz autos and they are now telling me the repairs will cost $5,800 There are many people online suffering because of this defect. There are reports online that once fixed, the issue returns months later. Wiz autos is asking me to pay 6000 for a repair and 3 month warranty on the part. Issue: Coolant leak is causing issues that affect the safety of drivers, as well as destroys their vehicles and KIA Motors has been the worst to work with.

Back seat got warm & later that morning car engine would not start but lights in vehicle came on. Appt made w/dealer who after a week hadn't done diagnostics nor checked battery & main hybrid fuse as I had requested. I towed to a service garage who upon starting to open the box covering battery, found battery had kindof exploded & bulged. I searched online for recalls on 12/7/22 and found a recall 11/10/22 -22V836000 (KIAs # is SC256) which is "Main Relay within Power Relay Assembly (PRA) may have inadequate connections between its contacts, causing increased electrical resistance, which can overheat the rear seats." "This recall supersedes NHTSA recall number 18V-666. Vehicles already repaired under the previous recall will need to have the new remedy completed" I have receipt showing I had did the 1st recall but the recall is not showing up when I search my VIN#. Kia has found some dealers lied & never replaced the part they said they did. My car will be towed tomorrow to a KIA dealer who will look into this issue & what my battery looks like. No warning lights came on prior to the engine not starting. I called KIA cust service for recalls this morning 12/7 and they were no help to me at all seeing the recall isnt showing under my VIN number.
