2017 Kia Niro Electrical Problems

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.

On or around March 20, 2026, my 2017 Kia Niro Hybrid experienced a complete failure of the high-voltage hybrid battery system, rendering the vehicle undriveable. The vehicle was towed to Kia of South Austin. As of the date of this complaint (74 days later), no diagnosis has been provided, no parts have been ordered with trackable confirmation, and no repair timeline has been given. Kia Techline corporate engineers are reportedly involved but have provided no resolution. A sudden high-voltage battery failure in a hybrid vehicle raises potential safety concerns I believe warrant NHTSA's attention, particularly given the extended inability to diagnose or repair the system.

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.

I have had ongoing electrical issues with my 2017 Kia Niro. First, the back passenger (driver side window) was working intermittently. The back windows from the day I bought the car brand new are rarely used, but when it was used for the 3rd or 4th time I had already gone over the miles where it would have been covered. The dealership was going to charge me almost $300, so I never fixed it. I just don't use the back windows. Then, the driver side low beam bulb kept going out. Erlich Kia in Longmont kept replacing the bulb despite my concerns of it being an electrical issue. Finally, the dealership was transitioned to Fowler Kia. By that time the issue was no longer going to be covered. Fowler eventually determined that the socket and harness assembly needed to be replaced. That was last year. Now, the passenger side headlight is having the same exact issue. I find it extremely frustrating that there are so many electrical issues that I have had with this car, and the dealership just doesn't care to try and connect any of the other issues. I also had to have my car towed twice to fix issues with it in the past. I have never had a car that I bought brand new have so many issues with it.

My car slowed, smelled hot, and then transmission overheat light came on approximately 130 miles from my home. I had it towed to nearest Kia service due to my warranty, Lehighton Kia dealer by AAA (Kia roadside wanted $293). Dealer claimed it was Clutch Actuator (said nothing about recall) and claim to be attempting to confirm warranty with Zurich for days with no success, I had no issue calling Zurich to confirm warranty would cover it. They said parts were unavailable in US, some in Korea, no guarantee where they would be distributed to and could not be ordered yet, so timeline of at least a month that I would be without a car. They could not offer me a loaner or rental. Last night I received Recall notice SC276 for the exact issue I am dealing with. In 4 calls to Lehighton Kia this recall was never mentioned. I bought my car in March with 31,000 with the best extended warranty I could buy to protect myself as a recent widow with a daughter in college. My car now has 52,000 and is not usable indefinitely, I cannot afford a rental and I work 35 miles away and feel that the Lehighton Kia has been less than helpful in dealing with this issue.

I was driving and the car was stuttering. Then after I stopped for a bit it resumed normal operations. Then the warning light came on, then it went off again. This happened for a couple of weeks until finally, while on a road trip at the end of July 2023, the car seemed to just lose power in 4th gear and I would have to really rev the engine just to keep it moving, that happened while on a road trip. I called the dealership several times during the trip and they said I’d already had the computer recall reset so they didn’t think it made any sense. I took it to my neighborhood repair shop when I got back and they said two spark plugs are shot, they replaced them and it ran fine. But now it’s stuttering again, just a few months later. I called the dealership again and they said I could bring it it for a diagnostic (not free) and then I got a letter about a recall. Not sure if it’s related to my issue because the dealer said probably not and said they’d call me when they knew more and my car had the computer issue not this one. No one has called and the car is still stuttering. I took it to the mechanic again and he said spark plugs look fine, but again, it is losing power in 4th gear, just around 45 mph only when I’ve been driving for more than two hours. I would just like the dealership to take a look and fix it.

During first recall 18V-666, Kia stated that I received a new PRA in September 2019 per recall instructions. July 2023, my car would not turn on and was sent to same Kia dealership. Recall 22V-836 applies to my car, and my PRA shows sign of thermal damage yet again. Both main relays that were replaced in 2019 were of Panasonic, yet, the PRA was melted to the point that the wire harness also needs replacing. This is 2 fire incidences in my 2017 Kia Niro in less than 3.5 years, on the same part.

I called my local Dealer Nationwide Kia in Timonium Maryland to get an appointment for the required recall. They have so far have been unresponsive, so I called Kia in California. I got a case # of [XXX] after waiting 1:30 mins on the phone. Called back the next week and they said they called the dealer and got no answer but left a message and they sent an email. Called back the next week and they said the dealer never responded and they sent another email. Called back today and sat on the phone with Kia California for another hour and they never answered. I'm very upset that i can't seem to get an appointment for a safety recall, what good does a recall do if the dealer won't answer me and the Kia Zone office can't force them into action.

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.

Intermittent failure of multifunction switch in steering column that controls lights, leading to loss of left-hand turn signal. Dealer checked bulb, socket, and wiring harness and could not reproduce the issue. This is a safety issue as it occurs without warning, lasts for days, and could cause an accident through inability to signal lane change or turn at intersection.

I HAVE TRIED ON THREE OCCASIONS TO HAVE THIS RECALL FIXED. EACH TIME, I LEFT THE CAR WITH THE DEALER, WAITED ALL DAY AND WAS TOLD THAT THE WORK WASN'T DONE BECAUSE THAT THEY HAS TO ORDER THE PART. THE FIRST TIME, COVINA KIA, SENT ME AN E-MAIL TELLING ME THAT I HAD CANCELLED THE APPOINTMENT, WHEN THEY CANCELLED IT BECAUSE THEY COULDN'T GET THE PART. THE SECOND TIME, THE PART WAS SUPPOSED TO BE IN STOCK BUT WAS AGAIN NOT AVAILABLE. THE LAST TIME WAS WITH CITRUS KIA. I CALLED KIA CUSTOMER CARE, REPORTED THE PROBLEM AND WAS PROMISED THAT IT WOULD BE RESOLVED. AS OF THIS DATE IT HASN'T. I BELIEVE, KIA IS STALLING THIS RECALL BECAUSE THEY DON'T KEEP PARTS IN STOCK. CURRENTLY, I HAVE TO WAIT UNTIL FEB. 6, TO HAVE THE WORK DONE. THIS IS LOS ANGELES WITH THOUSANDS OF CARS. I AM ESPECIALLY SUSPICIOUS OF THE E-MAIL AS IT MADE ME LOOK LIKE I HAD CANCELLED THE APPOINTMENT.

THIS CAR HAS BEEN IN THE DEALERSHIP 8 TIMES SINCE I PURCHASED IT IN FEBRUARY 2017. THE AIRBAG SENSORS WERE DEFECTIVE AND REPAIRED. THE CAR MALFUNCTIONS OVER A BRIDGE CONSTANTLY ON MY WAY TO WORK. KIA DOESN'T KNOW WHY IT DOES THIS. THE LATEST ISSUE IS THE TRANSMISSION FAILING IN TRAFFIC AND THERE BEING NO ACCELERATION. I'VE BEEN IN A LOT OF UNSAFE SITUATIONS BECAUSE OF THESE ISSUES. KIA CORPORATION HAS BEEN INVOLVED AND A TECH HAS BEEN FLOWN OUT TO INVESTIGATE MY CAR. I'M CURRENTLY SUING THEM TO REPURCHASE IT AS A LEMON. THIS COULD BE THE BEGINNING OF ISSUES WITH THIS MODEL. THEY HAVE HAD AIRBAG AND ELECTRICAL ISSUES WITH SEVERAL OTHER MODELS HISTORICALLY. NO ONE CAN TELL ME WHY MY CAR KEEPS BREAKING DOWN. I HAVE SEVERAL INVOICES AND PICTURES.
