  This recall specifically says my car it's a fire risk because of this recall. I have the HEV warning light on in my car on just as described in the recall notice but no Kia dealer wants to repair my car until the recall notice has a remedy from corporate. It's been over 2 months and still no actual recall remedy found. My car is still a fire risk with the HEV warning light on and the same kia dealerships don't want to fix my car due to no remedy. This is insane! Why did I buy this car? I spent 19k dollars in this car and right now is completely unusable. I would like my money back but it's too late for that. I'm going to contact a lawyer now since the company has identified a recall problem but it's not fixing it. I'm hoping the NHTSA can help me somehow. I'm giving my lawyer a copy of this complaint as well.

  Internal combustion engine coolant leaking out exhaust. The heat exchanger located in the catalytic converter system is leaking, leading to the ICE coolant draining. This leads to the engine overheating, and damage. Signs of the issue started with the coolant level lowering quickly, then the car heater stopped working. This confirmed by an independent mechanic.

  A FEW MONTH AGO, THE FRONT PASSENGER DOOR HANDLE FELL OFF WHEN TRYING TO OPEN THE DOOR WHEN THE CAR WAS PARKED/STATIONARY. THE VEHICLE WAS TAKEN TO THE DEALERSHIP, AND THE HANDLE AND COVER WERE REPLACED. TODAY, 10/22/2018, THE RIGHT REAR PASSENGER DOOR HANDLE POPPED OFF WHEN TRYING TO OPEN THE DOOR WHEN THE CAR WAS PARKED IN THE DRIVEWAY. BOTH TIMES THE DOORS WERE UNLOCKED, AND THE PRESSURE APPLIED TO DOOR HANDLE WAS MINIMAL (NORMAL). THE HANDLE BROKE IN THE SAME PLACE AS THE FIRST. WHEN CONTACTING THE DEALERSHIP, WE ASKED IF THE OTHER HANDLE (RIGHT REAR PASSENGER) COULD ALSO BE REPLACED, AS THIS SEEMS TO BE A DEFECT. THE SERVICE DEPARTMENT SAID THAT THEY COULD INSPECT IT WHEN REPLACING THE OTHER HANDLE, BUT COULD NOT ORDER PARTS UNTIL IT IS DETERMINED THAT IT IS BROKEN. UPON RESEARCHING THE PROBLEM ON THE INTERNET, WE FOUND THAT KIA HAD ISSUED TSB #TSBBOD180_R1 NHTSA ID #10151899, AND TSB #TSBBOD186 NHTSA ID #10151901 IN REGARDS TO THE DOOR HANDLES ON 2017/18 NIROS, AND SAID THAT ALL THREE PASSENGER HANDLES WERE TO BE REPLACED (NOT THE DRIVER). WE THEN CALLED BACK THE SERVICE DEPT AND INQUIRED ABOUT THE TBS, AND WERE TOLD THAT IT WASN'T FOR OUR VEHICLE. 2 HANDLES IN A COUPLE OF MONTHS WOULD WARRANT THE REPLACEMENT OF ALL HANDLES. WE DON'T UNDERSTAND WHY A RECALL HASN'T BEEN DONE, IF THIS IS AN KNOWN ISSUE, OR WHY OUR VEHICLE IS SUPPOSEDLY NOT INCLUDED IN THE TSB. IT IS A SAFETY ISSUE, AS ACCESS CANNOT BE OBTAIN FROM THE OUTSIDE OF THE VEHICLE.

  Got the recall letter but kia dealer and customer service have no info about when the remedy will be available. This is a major issue as I need to sell the car now to use the cash for other urgent matters. Dont even think the dealer will give a decent wholesale amount or take them on a trade. It is lowering the value and decreasing the demand as its a safety hazard for the vehicle which isnt fair . How long are they legally allowed to drag this out with no compensation to all those waiting ? Is there a class action suit ? Thank you for your help ! [XXX] [XXX] or cell [XXX] .

  On March 28, 2023 the vehicle HEV warning light came on. I called the dealership where I was informed they did not have any mechanics available to look at it until August. No one to work on Hybrid. I then took it to a mechanic shop, And I was informed to take it to the dealer. I could not drive the vehicle. I called KIA, Temple Hills back, I was told if you tow the vehicle here it will just sit. April 8, 2023 had it towed to another shop, the mechanic stated he thought it was the battery, which I was informed hybrid has 3 batteries, to check with the dealer to see if they had them, or could order one. Called the dealership Temple Hills, stathat they had never heard of a battery for that car. I was told to call back next week, after he spoke with the parts dept. manager. I called back a week later, and was told they knew nothing about a Kia Niro, could not help. The mechanic looked for a battery at other shops, ebay. The one I Paid 600.00dollars for did not work. After being there for 1 month. I called Kia dealership Bowie Md. On June 6, 2023 spoke with Jacob, the advisor. The vehicle was towed there, Jacob refused to give me any updates on the vehicle after 1 month being there, just sitting. I would call him trying to get updates, he informed me that they only had one mechanic, just a whole lot of nothing, the vehicle could catch on fire. Another month passed and I went to the dealership, along with my brother. Jacob was not answering my calls/returning them. Vehicle just sitting there. Jacob, then said the mechanic that worked on the hybrid was out for surgery, he would be in touch. I asked for the Kia Corporate number, which I received. I contacted Kia, corporate on July 13, 2023, spoke with them several times, informing them that the vehicle was not operable, and I was still making car notes/ paying insurance on a vehicle that I was not driving.

  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.

  My 2018 Kia Niro EX keeps overheating. We purchased the vehicle July 21st 2018. Three months after purchase, the vehicle dies, flashing warning lights and a message appeared to shut the engine off. Our car was towed to the dealership we purchased it from. After over three months, the dealership calls and tells us to pick the car up from them. The entire engine had to be replaced. We sued Kia Motors through the lemon law. We settled for the payment option because the engine was replaced. Now, our hands are tied due to once we took the cash settlement, we were no longer able to take legal action again if we had any additional issues. Over the course of the last three years, we had to have it repaired for a wiring issue, now, our vehicle continually overheats. Our dealership where we purchased the vehicle does not have a hybrid technician to work on it. We have to drive to another location of theirs to have it serviced. That location is over an hour drive. Our car is unable to be driven to have it properly service by the correct technician. There is an online forum, www.kianiroforum.com. This forum explains in detail what type of issue the consumer is experiencing with this vehicle. I am reaching out due to this overheating issue could cause serious harm to someone. We have spoken with Kia corporate headquarters, their advice is to have it looked at by a Kia dealership and they will go from there. We have exhausted all of our options to have these issues looked into and now reaching out to you for assistance. Myself included, it appears this vehicle has many many issues and needs to be brought to someone’s attention that has the power to get something done.

  The power train, engine, and breaks are defective. The vehicle has malfunctioned over 10 times in the past 5 months and it happens randomly. The same issues occur each time which where the car will not drive or will be extremely jolty, the gears will not shift, the breaks are delayed, and the engine will rev (RPMs will go up and down) when put in park. This has happened in the middle of an intersection and on major roads and highways. This issue puts myself and others around me at risk. The problem has been reproduced at an authorized Kia dealership and has been attempted to be fixed on many occasions. It has been inspected and serviced by Kia service technicians. There are many warning lights and error messages that appear when the malfunction happens including: check engine light, hybrid battery light, ABS system warning, BDS system warning, emergency braking system error message, electric power steering light, master warning light, engine oil pressure light, charging system light, regenerative breaking warning light, along with engine control system and battery control system error warning messages.

  NO INCIDENT TO REPORT. DESIGN SAFETY ISSUE. THE DESIGN OF THE EMERGENCY LIFTGATE SAFETY RELEASE REQUIRES THE USE OF THE VEHICLE'S MECHANICAL KEY TO EXIT THE VEHICLE THROUGH THE REAR LIFTGATE IN AN EMERGENCY (SEE OWNERS MANUAL PAGE 4-26. THE NEED TO HAVE A KEY IN HAND UTTERLY DEFEATS THE INTENDED CONCEPT OF AN EMERGENCY RELEASE. THIS DESIGN WOULD BE COMPLETELY UNACCEPTABLE FOR THE TRUNK OF A SEDAN AND IT SHOULD ALSO BE UNACCEPTABLE FOR A HATCHBACK OR LIFTGATE. A RELATIVELY INEXPENSIVE FIX WOULD BE TO INSTALL A SIMPLE METAL LEVER IN THE DOOR THROUGH THE SLOT PROVIDED FOR INSERTING THE KEY. I HAVE HAD OTHER VEHICLES WITH SIMILAR EMERGENCY RELEASE MECHANISMS. I DO NOT KNOW HOW WIDE SPREAD THIS IS THROUGH THE INDUSTRY OR IF THERE ARE IN FACT DIFFERENT STANDARDS. I WOULD URGE NHTSA TO REQUIRE MANUFACTURERS TO MAKE ALL DOORS OPENABLE FROM THE INSIDE WITHOUT THE NEED FOR A KEY OR ANY OTHER TOOL, ESPECIALLY WHERE IT IS SPECIFICALLY IDENTIFIED AS AN EMERGENCY MEANS OF EXIT.

  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'.

  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.

  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.

  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.

  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.

  The car can slow down suddenly in the middle of traffic even if I accelerate. The engine has a problem according to the mechanics who was trying to fix my car twice without succes. The car does not hold coolant liquid for more than 15 minutes. It looks like the coolant is staying somewhere in the engine. It overheats too. Yes the car is available for inspection upon request. It's a high risk because the car can suddenly slow down in the middle of traffic or when leaving a light turned green. And the last time I drove it there a weird smell. Yes, an independant service center located at College Park Maryland informed me about the issue. The vheicle or compenent has not been inspected yet by the manufacturer, police, insurance representative or others. When the car starts slowing down in the middle of traffic, I feel a kind of vibration first on the gas peddale and comes up the engine light. This happened last month

  WIRING HARNESS CHEWED UP BY RODENTS 6 WEEKS AFTER BUYING CAR NEW. ONLY 1900 MILES ON CAR. CAR WAS PARKED BETWEEN '01 TOYOTA TACOMA AND '04 F250 DIESEL, WHICH HAVE BEEN THERE SINCE NEW WITHOUT PROBLEMS, AS WAS A '06 VW DIESEL, AND A '12 VW DIESEL, ALSO PARKED THERE SINCE NEW. THE USE OF SOY BASED INSULATION ON THE WIRING HAS TURNED VEHICLES INTO ROLLING FOOD SOURCES. WITH CRITICAL FUNCTIONS NOW CONTROLLED ELECTRICALLY RATHER THAN MECHANICALLY (THROTTLE TRANSMISSION AND STEERING), THIS A MAJOR SAFETY HAZARD, NOT TO MENTION EXTREMELY COSTLY $2000 TO $5000 TO REPAIR. THIS IS OCCURRING AT EPIDEMIC RATES, AND IS ACROSS ALL MAKES. DON'T LET THIS TURN INTO ANOTHER "TAKATA".

  On 2/15/2022 around 10:00AM, I was driving my vehicle as normal. Noticed brake lights ahead, I was about 3 car lengths back, which I always try to drive since I am on the road a lot and I prefer not to have an accident. Well this time, I put my foot on the brake as normal and the vehicle felt like brakes were not even working, pushed harder with my foot and waited for that pumping feeling (which I have felt before) and literally nothing! Once I was about a car lengths away, I knew my vehicle was not stopping so I sat up straight and leaned back before the air bags deployed in my face. I have since come home and found several complaints from other 2018 Kia Niro owners that have made a complaint about this on other forums and with the NHTSA and Carcomplaints.com - This issue has been ignored by Kia about braking system.

  Fire warning recall notice issued in July 2023. Follow up with both Kia and with Kia dealership that I purchased the vehicle from still says that there is no fix to this problem. THE PRINTED CIRCUIT BOARD (PCB) IN THE HYDRAULIC CLUTCH ACTUATOR (HCA) MAY BECOME CONTAMINATED WITH FLUID. A FLUID-CONTAMINATED PCB MAY LEAD TO AN ELECTRICAL SHORT CIRCUIT, THEREBY INCREASING THE RISK OF AN ENGINE COMPARTMENT FIRE WHILE DRIVING. With the potential of a fire risk while driving, why is the manufacturer not required to remedy this situation in a more timely manner. It has been over 6 months since the recall was issued yet the manufacturer is allowed to continue producing vehicles but not required to repair those vehicles that may be affected and cause significant risks to the driver at potentially other property. NHTSA should mandate inspection and repairs of recalled vehicles which should take a priority to the manufacturing process. Vehicles with recalls should not be allowed to go without repair especially when accidents are imminent and life-threatening injuries may occur. Additionally, trying to get an appointment with a local Kia dealer where I purchased the car has a wait of well over a month for them to even inspect the car. Between Kia not taking care of their vehicles and their dealers not being able to service vehicles, NHTSA really needs to evaluate this and create remedies for the safety of the vehicle and the driver. Waiting over 6 months for a recall is frustrating, dangerous, and unacceptable. Manufacturers need to take responsibility for recall notices and repairs in a much more timely manner. Safety over profit should be a priority. On a personal note. I purchased my Kia Niro hybrid new in 2018. It is one of the best cars that I have purchased in my '76 years. I have had virtually no problems with the vehicle and was a big proponent of Kia, but their lackadaisical attitude on recall repairs as really put a damper on my respect for their management and
