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.

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.

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.

Problem 1, Check Engine Light: I purchased the used car on Jan 9 2025, around 23,400 miles from Kia Dealership, capitol Expy in San Jose. Today 05/27/2026, the odometer reads 26, 407 miles. My car is used only twice a week - 20 miles on Fridays, 12 miles on Wednesdays. My car has less than minimum wear and tear and is barely used. I completed my 25K service after Thanksgiving in Nov 2025. I have not even driven 1500 miles and the car is back in for service. Prior to this, within a month of purchasing my car Kia replaced the battery in my car. Around Mar 15, 2026, the Check Engine Light displayed. I called the Kia Dealership on Capitol Expy in San Jose 3-4 times, but they Kia dealership don't call back. On 05/15/2026, for the first time I drove about 50 miles return trip. While driving North on I-280 from [XXX] to [XXX] , over rolling hills that had some incline, the Check Engine Light came on.I scheduled service. I experienced that the vehicle struggle to climb the incline of rolling hills, after the battery charge was exhausted and the engine was running only on gas. The gas was 3/4 full. This is a safety hazard for me to be interrupted by Check Engine Light twice while driving and that too when my car has not even completed 30K miles. My car is sin Service on 05/26/2026 and in the shop for 3 days diagnosis. The Kia Dealership has yet to determine the problem. I have had to rent my own rental car even though I purchased Extended Warranty on the car. Problem 2, Blind Spot Warning Light on right side mirror: On 05/13/2026 and on 05/22/2026, the Blind Spot warning light on right side mirror does not display oncoming traffic when my car is parallel to the lane markings. On 05/13/2026, I was driving at 30mph and on 05/22/2026 I was stationary in the center divider. In both instances, the passing driver had to honk at me really loud -- to avert an accident. Both problems are severe safety hazards. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

A major drivetrain service and repair was completed by an authorized manufacturer dealership. After picking up the vehicle, an unusual front-end/steering noise was immediately reported to the staff. Over just 390 miles of driving, the symptom worsened. A subsequent formal inspection by a separate, independent authorized service center confirmed the root cause of the safety failure: the primary axle nut had been left completely unstaked during the initial drivetrain assembly, rendering the vehicle entirely unsafe to operate. The vehicle was grounded to prevent an accident. Because the mandatory safety protocol of staking the axle nut was omitted, the critical fastening hardware was allowed to back off under normal driving conditions. This component failure directly compromised the structural integrity of the front drivetrain, steering knuckle, and wheel hub assembly. Had the vehicle continued to be driven, the omission presented an imminent risk of complete mechanical separation, which could cause a wheel assembly to detach or lock up while in motion at high speeds, putting the safety of the occupants and other motorists at extreme risk. The vehicle remains grounded and is available for inspection. The safety-critical assembly failure has been fully documented by the inspecting service center via technical video (available upon request) and photographic evidence. The manufacturer has been notified of the dealer workmanship defect but has failed to authorize corrective action or safe transport of the vehicle to a certified facility for remediation.

Car seat lower hip straps frayed on both sides. Had we been in an accident I have no doubt the strap would have ripped. I have 3 personal friends who checked their same Evenflo Revolve 350 car seat to find fraying in the exact same spots. And dozens of posts online with pictures showing the exact issues as well. The integrity of that straps in these seats are obviously compromised for so many people to be having them fray in the exact location. Evenflo is telling us all it's due to "external factors such as a mouse" but it would not all be the same car seat it happens to, in the exact same place on the seat, to people who drive their vehicles daily and have no other wings of rodents in their vehicle or issues with the other car seats installed in the vehicle.Baby/children's car seat safety is SO important and the strength of these straps needs investigated before someone is in a crash and their child's harness rips! Uploading my own personal photos-but I have many screenshots of pictures and posts from others having the same issue that I can provide upon request.

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.

Situation: Slowing on exit lane from freeway while in I-Pedal mode. Anomaly: As i gradually lifted the accelerator pedal, at about 61 mph the car strongly accelerated. My response: I lifted my foot entirely off the accelerator pedal and scanned the dash to confirm that cruise control was not active. Acceleration continued. I tapped the accelerator pedal and the acceleration stopped. We were now at 69 mph and close to the car in front of us.

am writing to formally request assistance regarding my Kia vehicle which I purchased used at approximately 38,000 miles. Shortly after purchase, the vehicle became undrivable and has since required repeated repairs without resolution. To date, the vehicle has been presented for repair on six separate occasions for the same issue and has remained out of service for a significant period of time. Based on these repeated failures and lack of resolution, the vehicle may reasonably be considered defective at this point. Despite being unable to use the vehicle, I have continued to make monthly payments, resulting in considerable financial hardship. In an effort to resolve this matter, I consulted with a Maryland MVA investigator, who advised me to contact Kia directly and report that the vehicle appears to have been sold with a pre-existing defect. I have also communicated with the selling dealership, Eastern Motors; however, I was informed that due to changes in management, they are unable to provide further assistance and consider the matter outside of their control. Additionally, I have previously reached out regarding this issue and have not received a response. Given the timing of the failure, the repeated unsuccessful repair attempts, and the extended period the vehicle has been out of service, I respectfully request that Kia conduct a thorough review of this matter. I am respectfully requesting Kia’s assistance in resolving this matter. Specifically, I would like to explore options such as a replacement vehicle, repurchase (buyback), reimbursement of payments made, or other goodwill support. I remain open to a fair and reasonable resolution. Please advise what documentation or additional information is required to proceed. I am prepared to provide all relevant records, including purchase documentation and complete service history. Thank you for your prompt attention to this matter. I look forward to your response.

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)

10.25" audio head unit. UVO no longer connects so that 911 and roadside assistance can not be reached. This is a known problem with 2019 and early 2020 Kia Niro's part# 96160-Q4210. I spoke to the Kia UVO Call Center and they confirmed that my unit is not communicating and has not since Dec. 2021. As I usually drive just around town I have not used UVO, but now that I'm on the road I need to be able to use this feature. I'm attaching a quote for a replacement unit

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 had my oil changed in Dec. 2025. I drove 1000+ miles w/no issue. Engine suddenly seized w/no engine light warning. Oil dumped all at once. Kia refuses to cover under warranty. THIS HAPPENED TO MY CAR: NTSA announced it had launched an investigation into Hyundai Motor Company and Kia Motor Company for problems with their oil pans and oil drain plugs... consumers have filed complaints their engine’s oil drain plug falls out, causing all the oil to drain out of their engine while driving. In multiple tests the oil drain plug was tightened according to factory torque specifications and the tightening was well documented. Yet, testing shows in multiple cases that while driving, the oil drain plug falls within a few thousand miles after the service. In those cases, the crankcase drained completely. The Hyundai and Kia drain plug falls out due to inferior oil pan material and the drain plug gasket. The testing and investigations appear to show that the oil drain plans are made with THIN METAL AND THE DRAIN PLUG MOUNTING IS POORLY REINFORCED. In addition, the oil pan is coated with a thick paint coating the bonds the gasket to the pan, so the gasket does not come off when the drain plug is removed. That gasket issue alone is not why the oil drain plug falls out, but it is a factor in the chain of events. The oil pan is the biggest problem Apparently, the thin metal, along with engine vibrations and expansion/contraction tend to loosen the drain plug without any other intervention. NHTSA is investigating this as a factory defect ... The problem is two-fold. First, even if the repair shop properly torques the drain plug, the oil drain plug falls out on its own. The customer then blames the shop for shoddy workmanship. Second, Hyundai and Kia dealers are telling customers that servicing their vehicle at an aftermarket shop automatically voids their factory warranty. This is totally false & actually illegal under the terms of the Magnuson-Moss Warranty Act.

Intermittent warning to "Refill Inverter Coolant" displays on the dash screen. This is a known issue pursuant to SA512 (ELE 270 Rev 3) due to faulty coolant that crystallizes and interferes with the sensor. However, per Kia, it is only covered under standard warranty (5 years/60k miles) and while my vehicle is within the year warranty, it is over the mileage. Quote was to replace "Chiller, water pump and flush coolant system" at a cost of $2369.02 including parts and labor. Dealership will not perform recommended maintenance of coolant flush (every 37k miles) without replacing these parts. If this was a known defect why is there a limitation to the SA? It should be covered as a recall, not a voluntary service alert. I am unable to properly monitor the in-dash warnings regarding coolant levels until this problem is fixed

On now 4 occasions--intermittently my car will go into drive when shifted into the reverse shift I don't know what component is impacting this. My safety and others safety is at risk by my car literally going forward when it's supposed to be in reverse. I've taken my car to the dealership two times and they have not been able to recreate it or fix anything. I've reached out to KIA corporate for a resolution but have not gotten follow up: Case#XXX (case where I was supposed to get a response from a case manger) and XXX (original case). To my knowledge I don't know if it's been inspected by the manufacturer, police, insurance representatives or others No warning lamps or signs. It happens intermittently and seemingly no rhyme or reason when it happens. This happened back in November 2025 and most recently this April.
