POWER TRAIN, ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
COMPONENT/SYSTEM: The 12-volt auxiliary battery system, the interior fuse box (Total Integrated Power Module) containing an auto-cutoff relay, and the high voltage battery system. All components are available for inspection. SAFETY RISK: The vehicle has lost power and died while being driven, and has left occupants stranded on multiple occasions. A sudden loss of motive power in traffic creates a serious risk of collision to occupants and to other motorists. The vehicle has failed to start dozens of times. FAILURE DESCRIPTION: The 12-volt battery in my 2022 Kia Niro EV has repeatedly discharged, leaving the vehicle dead and unable to start. ~Six 12V batteries have been installed between January 2025 and February 2026, between 60,431 and 77,130 miles. CONFIRMED BY DEALER: Yes. The condition has been reproduced and documented by the dealer across five separate repair orders. On 1/21/2025 at 60,431 miles, the technician found the 12V battery completely dead after sitting, jump-started the vehicle, and reported no abnormal draw on the electrical system. On 11/05/2025 at 74,355 miles the vehicle again required a jump start to be brought into the shop; the battery was replaced, and the technician reported the vehicle was operating as designed. On 1/22/2026 at 77,124 miles, a technician performed a parasitic draw test and measured 0.185 amps, exceeding the specification of below 50 milliamps by approximately 3.7 times. The technician documented that the auto-cutoff relay was remaining closed, continuously supplying current to 21 modules, and that the interior fuse box required replacement at a quoted cost of $2,048.48. This defect was present during the two prior visits but was not identified. On 2/13/2026 at 77,130 miles, the vehicle would not start when we came to pick up the car. The shop had to provide a loaner, and then another battery was installed, and the TIPM was replaced.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
This submission is supplemental information for my prior NHTSA complaint (Complaint #XXX). After filing the original report, I learned additional details from the Kia dealership that serviced my vehicle. The service department stated that they have seen the same electronic parking brake controller and actuator failure on multiple Kia Niro vehicles from model years 2018–2021. They reported that these failures were not covered under warranty for those years, even when the symptoms began during the warranty period. The dealer also explained that Kia made design improvements to the electronic parking brake system in later model years and expanded warranty coverage for the updated EPB assembly and control components. This suggests that Kia was aware of recurring issues with the earlier design, despite no formal recall or service campaign being issued for the affected 2018–2021 vehicles. I am submitting this supplemental information because it indicates a potential pattern of safety‑related failures involving the electronic parking brake system across multiple vehicles and model years. These failures affect the vehicle’s ability to hold position when parked and may interact with braking and stability control systems.”

UNKNOWN OR OTHER
There's a problem with the horn in my car. Either the high or low. The problem is intermittent and the horn will fail and it is not available in emergency situations. I brought this to the dealership and made them aware but they refuse to take this seriously and two adequately evaluate the car. They blew the horn and said it was working. It was not working and I said it was intermittent and they said well we could not find any problem. There were no warning lights. Nothing else. The horn is just intermittently failing.

POWER TRAIN
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'.

STEERING:LINKAGES:TIE ROD ASSEMBLY, WHEELS:HUB
The contact owns a 2023 Kia Niro. The contact stated that while her husband was driving at 40 MPH, the vehicle hydroplaned and pulled to the left unexpectedly. The contact initially contacted the dealer and was informed of the headlamp replacement and general inspection. Additionally, while the contact's husband was driving, the driver-side front tire experienced a blowout near a service station; the technician advised that the tire exhibited steel tread. An independent mechanic attempted a wheel alignment but discovered a rusted, bent tie rod, preventing the service. Following dealer instructions, the vehicle was towed to the dealer, where the wheels, both hub bearings, tie rods, and brake calipers were replaced. Despite the repairs, the owner refused to reclaim the vehicle due to the recurring mechanical defects. The manufacturer was not notified of the failure. The failure mileage was approximately 71,000.

Driving through intersection making a left turn and a driver blew the light at 45-50 (speed limit is 45 on road) t-boned the vehicle. Air bags did not go off even hitting the zone on the car front passenger door. I have pictures and police report if needed. I contacted Kia and haven’t heard back. This was a rental car through Dollar Rental at Orlando Intl Airport. It was not drivable.

SUSPENSION
I purchased this vehicle new from the dealer last year. The second time I went to them for an oil change the tires were worn out oddly and needed to be replaced. They said the car needed an alignment that I had to pay for. I purchased replacement tires from another shop and had the alignment paid for at another shop. The dealer refused any responsibility. This vehicle has not been in any accidents and miles driven are highway miles

POWER TRAIN
What's malfunctioning: coolant monitoring system shows low coolant warning when coolant level is observably fine. Problem has been ongoing for over a year. Available for inspection: yes. Safety problem: coolant monitoring is inaccurate, causing alarm when coolant levels are fine and possibly causing no alarm when coolant levels are too low. Problem reproduced: yes, by both dealer and independent service center. Vehicle inspected by manufacturer: yes. They attempted service but their repair only lasted a few months. Symptoms prior to failure: no. The problem is that the warning lights are turning on when they should not be. This matches the symptoms of Kia Technical Service Bulletin SA512, but the manufacturer's fix did not work.

SERVICE BRAKES, FUEL/PROPULSION SYSTEM
My car is a 2019 KIA Niro Hybrid. It's only 7 years old, and my husband and I have been the only owners. It only has 61,000 miles on it, and it is serviced regularly and has to pass a state emissions test each year. As I was driving the other day, the dashboard lit up with critical alerts saying "check regenerative battery" and the braking system went completely soft; I could not stop the car using the brakes. It was terrifying. I had to pull off the road and use the emergency brake to stop the car. This was an awful incident that could have resulted in deaths or serious injuries. Again this is for a car that is well-maintained and well under 100,000 miles.

BACK OVER PREVENTION
The contact owns a 2020 Kia Niro EV. The contact stated that the rearview camera intermittently failed to display an image when the vehicle was shifted into reverse. The contact stated that reverse engaged normally, and the audible alert was sounded; however, the display screen periodically remained blank. The contact stated that the failure was intermittent but had occurred several times. The contact stated that the rearview camera operated properly for a while before the failure reoccurred. The vehicle was taken to a dealer prior to the expiration of the warranty. The dealer was unable to duplicate the failure, and the vehicle was not repaired. The manufacturer was notified of the failure and suggested that the vehicle be taken for additional diagnostic tests, and the dealer would consult with technical assistance from the manufacturer to determine how to repair the vehicle. The failure mileage was approximately 11,000.

POWER TRAIN
Our 2019 Kia Niro EV (approximately 138,000 miles) exhibits an abnormal rumble/growling noise from the front drive unit while driving slowly in "D" range and when accelerating or decelerating between 0–25 mph. This symptom matches exactly the condition described in Kia Technical Service Bulletin ELE234 (Rev. 1, April 2021): "Drive Unit Inspection & Replacement for EV Motor Rumble Noise," which covers all 2019MY Niro EV vehicles produced from December 5, 2018. To our knowledge, TSB ELE234 has never been performed on this vehicle. The repair involves replacement of motor/roll mount brackets and, if necessary, traction motor or reduction gear replacement. Kia has a documented, tiered repair procedure for this exact issue with assigned labor operation codes. The failure presents a safety concern because drivetrain noise at low speed can precede loss of drive power or sudden drivetrain failure, which creates a hazard in traffic, intersections, and during highway merging. Despite the existence of this TSB since April 2021, NHTSA appears to have few or no formal complaints logged for this specific defect, meaning it has not triggered the regulatory scrutiny it warrants given the documented widespread nature of the issue. I am requesting that NHTSA investigate whether a formal recall of affected 2019 Kia Niro EV vehicles is warranted for this drivetrain defect.

This complaint supplements a previously submitted report filed today, June 18, 2026, (Original is Complaint Number: 11845044) regarding the same vehicle and condition (TSB ELE234 drive unit rumble noise). The correct VIN for this vehicle is [XXX] — a 2019 Kia Niro EV EX Premium, 138,457 miles. I am filing on behalf of the vehicle owner, [XXX], who has authorized me to act as his advocate. The owner is a Ukrainian speaker and I am assisting with all documentation and communications. In addition to TSB ELE234 (drive unit motor rumble, April 2021), this vehicle is also subject to Kia Service Action SA512 (April 2023): Inverter Coolant/Debris Flushing for the "Refill Inverter Coolant" cluster warning, affecting 2019–2022 Niro EVs produced May 10, 2019 through October 4, 2021. SA512 has also not been confirmed as completed on this VIN. CARFAX records document multiple authorized Kia dealer visits — at Roseville Kia and Folsom Lake Kia — between 2019 and 2022, during the period both ELE234 and SA512 were active and applicable. Neither service action was applied during those visits. This filing requests that NHTSA investigate both the safety implications of the ELE234 drivetrain defect and the broader pattern of authorized Kia dealers failing to notify owners of and apply active service bulletins during routine service visits on affected VINs.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The electronic parking brake controller failed after intermittent warnings that began while the vehicle was still under warranty. The parking brake actuator also failed and had to be replaced. The electronic parking brake system is part of the vehicle’s safety system, and the failure caused the parking brake to malfunction unpredictably. The issue did not store persistent diagnostic codes, making it difficult to diagnose earlier. This is a safety concern because it affects the vehicle’s ability to hold position when parked and can interfere with braking and stability control. Because I am not the original owner, Kia refused to perform this as a warranty repair even though the intermittent failures began while the vehicle was under warranty.

ELECTRICAL SYSTEM, POWER TRAIN, VEHICLE SPEED CONTROL
Check electric vehicle system warning light indicator illuminates and car stops driving on highway! A/C and defrost won't work properly and when turned on causes the above warning light and malfunction. Car will not charge at "fast" charging stations and will leave you stranded on highway. I live in [XXX] and the vehicle only does it when humidity is high outside. Issue also causes problems with the 12V battery. SEVERE SAFETY ISSUE WHEN CAR SHUTS DOWN IN THE MIDDLE OF THE HIGHWAY DRIVING AT ANY SPEED. It is the system ICCU (Integrate Charge Control Unit) that KIA has a limited warranty coverage on and should be reviewed for recall.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
I was travelling on a road today and was in the right hand lane with adaptive cruise control on. I then switched lanes to the left hand lane (it's only 2 lanes) and the adaptive cruise control was still on. I noticed the car travelling faster than it should be for there being a stopped vehicle ahead. I was prepared to stop on the brakes and luckily I was! The collision warning came on and I immediately applied the brakes. How is it that the collision warning came on before adaptive cruise control came on? This is at least the 3rd time something like this has happened.

The Hydraulic Clutch Actuator has caused functional driving issues and caused my vehicle to go into limp mode. I was never informed of the recall issue prior to purchase, and the recall was marked as complete, when it was not. The fix for KIA NIRO Recall SC276 was incomplete in January 2024, and I purchased my vehicle in April 2024. My issues started in November 2025, and the incomplete recall issue has been ongoing. KIA offers only a 1/2-way fix, and this is simply not acceptable.

The contact owns a 2022 Kia Niro. The contact stated that while driving from a complete stop at 5 MPH, the vehicle was T-boned on the passenger's side by a Jeep Grand Cherokee driving at high speed. Due to the impact, the contact's head struck the dashboard. The other vehicle fled the scene of the crash. The airbag deployed on the passenger side but did not deploy on the driver's side. No warning light illuminated. There was no reported fire. A police report was filed. The vehicle was towed to a tow lot, where the contact was informed that the vehicle would be destroyed. The contact sustained an eye and face injury, body aches, and a detached ear. Medical attention was received at the hospital, where the contact was stabilized and referred to the Primary Care Physician for future care. The contact called both an unknown local dealer and an independent mechanic, but there was no response. The manufacturer was not contacted. The contact called the auto finance company and was referred to the insurance company. The failure mileage was unknown.

UNKNOWN OR OTHER
The AC compressor failed due to an isolation resistance failure at the high voltage inverter. Freon leaked from the AC system into the battery chiller coolant loop, causing crystallization and blockages in the inverter coolant circuit. This is a battery thermal management system failure. The failure was confirmed and diagnosed by an authorized Kia dealer. Warning lights appeared on the dashboard including an inverter coolant warning. The vehicle was driven in ambient temperatures exceeding 108 degrees Fahrenheit in Arizona with no cabin cooling and a compromised battery thermal management system, creating a safety risk to the driver. The dealer quoted repair including AC compressor replacement, battery chiller replacement, and inverter coolant flush. Kia Consumer Affairs denied warranty coverage under the federal emissions warranty despite the vehicle being within the 8 year/80,000 mile coverage window at approximately 58,309 miles. No written explanation for the denial was provided. This failure appears to be a known pattern on this platform based on owner reports. The battery chiller and inverter coolant system are integral to battery thermal management and should be covered under the federal emissions warranty. The vehicle is currently unsafe to operate in extreme Arizona heat without functioning thermal management.
