FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, UNKNOWN OR OTHER
My 2024 Kia Niro Hybrid has experienced multiple issues that I believe should be documented. The vehicle previously displayed an Electronic Parking Brake (EPB) warning. It was taken to an authorized Kia dealership for diagnosis and repair. Although repairs were performed for the EPB-related issue, I am submitting this report so the condition is documented if similar reports are being received from other owners. In addition, the vehicle developed a persistent creaking/clicking noise during forward driving. The noise was not present when the vehicle was new and began after normal use. It is most noticeable during forward driving and is not heard while backing up. The vehicle has been inspected by an authorized Kia dealership on multiple occasions, including a ride-along with a technician. After evaluating the vehicle, the dealership advised that the noise was normal and that the vehicle was functioning as intended. No additional repair was recommended. Although the dealership concluded the noise is normal, I remain concerned because the noise did not exist when the vehicle was new and has persisted. I am submitting this complaint so NHTSA has a record of the issue and can determine whether other owners are reporting similar conditions that may warrant further review.

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.

VISIBILITY/WIPER
The interior surface of the windshield freezes during cold weather operation, beginning at the edges of the windshield and progressing toward the center directly into the driver’s line of sight. This significantly impairs visibility and requires approximately 20–30 minutes of vehicle warming before safe operation is possible. The condition has occurred repeatedly since November under normal winter temperatures. No warning lights or system messages appear prior to the event. The vehicle has fewer than 8,000 miles. The vehicle has been inspected multiple times by authorized dealerships. Three separate dealerships performed diagnostics and preventative service, including cleaning A/C drains and ventilation components; however, the condition persists. Dealership personnel advised they could not open a technical case unless the freezing could be observed in person, which has prevented further escalation because the condition is temperature-dependent. Photos and videos documenting the freezing have been provided to the manufacturer and dealerships. The issue has not been resolved and continues to present a safety concern because driver visibility is obstructed during normal winter driving conditions. The suspected cause is improper windshield installation or sealing allowing moisture intrusion, although the exact failure mechanism remains unconfirmed.

ELECTRICAL SYSTEM
The 12-volt battery system in my 2024 Kia Niro (VIN: [XXX] ) has suffered two total failures in under one year of ownership (approx. 10,000 miles). In both instances, the vehicle was completely unresponsive, with no power to essential systems. Safety Risks and Incidents: 1. [XXX]: Vehicle experienced a total power loss. It would not start and all electrical systems were dead. 2. [XXX]: Identical failure. These failures create a significant safety risk by potentially stranding the driver in hazardous locations and disabling critical safety systems, including hazard lights, power steering assist, and emergency braking. If a total power loss occurs while the vehicle is in motion, it could result in a sudden loss of motive power and control, posing an unreasonable risk of accidents or injury. Dealer/Manufacturer Confirmation: The problem was confirmed by Ourisman Kia of [XXX] ). The dealer replaced the 12-volt battery after identifying diagnostic code D04 ("Insufficient Battery Charge Condition Identified"). Despite proof of regular use (1,000 miles/month), Kia America has denied warranty coverage, claiming "insufficient driving". Warning Symptoms: There were no warning lamps or messages prior to either failure. The vehicle functioned normally until it became completely inoperable. I have since installed a third-party battery monitor to mitigate the risk of being stranded by a third failure. Evidence of Trend: A technician at the dealership noted a similar 12V failure in another new 2024 model (Carnival). Numerous other 2024 Niro owners report identical "parasitic drain" issues on NHTSA and consumer forums, suggesting a systemic manufacturing or software defect in the charging system.

UNKNOWN OR OTHER, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
Forward collision system fully activated while driving eastbound in the fast lane on [XXX] . The sun was behind me. No glare. No cars or objects were in front of me or next to me. The dashboard started flashing and warning sounds activated and the car slammed on the brakes itself. The seatbelt locked up and left me bruised. Miraculously, the cars behind me avoided crashing into me while I accelerated out of it. I could have been killed. Dealership minimized my concerns. I don’t want to drive this car ever again unless someone can make sure it doesn’t happen again. This safety feature malfunctioning is a death trap.

ELECTRICAL SYSTEM, TIRES, ENGINE
The contact owns a 2024 Kia Niro. The contact stated that while driving at approximately 65-70 MPH on the highway, the radio panel went blank. The vehicle was blowing cold air on the driver's side while the passenger’s side was blowing hot air. The contact stated that there was slush on the driveway and the vehicle slid. There was a triangle symbol with an exclamation mark displayed. The message that the camera had disengaged was displayed. The contact turned off the vehicle, and the vehicle failed to restart. The contact attempted to start the vehicle and after several hours, the vehicle started. The vehicle was taken to the local dealer, where it was diagnosed that rodents had built a nest in the engine due to the soy-based insulated wires. The dealer noticed a mouse, nuts, and seeds after disassembling the vehicle. The dealer ordered an electrical wiring harness. The dealer called the tire manufacturer, who confirmed the tires were working as designed. The contact replaced the tires. The vehicle was not repaired. The contact called and notified the insurance company of the issues. The manufacturer was not contacted. The failure mileage was approximately 9,999. The VIN was not available.

AIR BAGS, ELECTRICAL SYSTEM
What happened? While driving my 2025 KIA Niro on [XXX] , I stopped at a red light behind another vehicle. Suddenly, my car was rear-ended by another vehicle, causing a significant impact that pushed my car forward into the vehicle in front. The seat belts deployed but I sustained a broken nose from hitting the steering wheel. My daughter and I were taken to the hospital for treatment. Component or System that Failed or Malfunctioned: The floor wiring assembly beneath the front passenger seat, which may have prevented the front airbags and seat belts from deploying properly, and could have caused an unintended side curtain airbag deployment. The vehicle is available for inspection upon request. Safety Risk: The malfunction posed a serious safety risk as the airbags and seat belts may not have functioned as intended, increasing the risk of injury in the event of a crash. Reproduction of the Problem: The problem has not been reproduced or confirmed by a dealer or independent service center yet. Inspections: The vehicle has been inspected by the police and insurance representatives after the accident. Warning Lamps, Messages or Symptoms: There were no warning lamps, messages, or other symptoms of the problem prior to the failure. Best Assessment of Incident and Cause: The recall notice issued by KIA indicates that the floor wiring assembly beneath the front passenger seat may become damaged, which can prevent the front airbags and seat belts from deploying properly or cause an unintended side curtain airbag deployment.

Carry Handle, Shell, Base
The car sear base comes with a plastic seatbelt guide. When you install the car seat using the anchors, tighten the belt and press down on the tightening lever, a piece of the plastic guide bows upward and causes the car seat to become stuck when rotating. Evenflo asked for it back and sent the same one model which is having the same issue.
