NHTSA lists 2 safety recalls and 16 owner complaints for the 2024 Kia Niro. Most complaints involve electrical system (6) and forward collision avoidance (3). The EPA rates it 49–113 mpg combined, and NHTSA gives it 5 stars overall.
Kia America, Inc. (Kia) is recalling certain 2023-2025 Niro EV, Plug-in Hybrid (PHEV), and Hybrid vehicles. The floor wiring assembly beneath the front passenger seat may become damaged, which can prevent the front air bags and seat belts from deploying properly or cause an unintended side curtain air bag deployment.
Kia America, Inc. (Kia) is recalling certain 2023-2024 Niro EV and 2023 EV6 vehicles. One of the drive shafts may have been improperly heat-treated, allowing it to break under load and resulting in a loss of drive power.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“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…”
“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…”
“I have experienced two incidents of sudden, severely reduced propulsion while driving my 2024 Kia Niro Hybrid. The incidents occurred several weeks apart. During both incidents, pressing the accelerator did not produce normal acceleration. The vehicle continued moving with very limited propulsion, but the gasoline engine remained at 0 RPM and did not engage when additional power was requested. There were no warning lights, error messages, or other indications of a malfunction on the dashboard. During both incidents, I shifted to Neutral and back to Drive while safely coasting, but this did not correct the problem. After coming to a safe stop, placing the vehicle in Park, turning it completely off, and restarting it, normal acceleration and gasoline-engine operation immediately returned. After the first incident, the vehicle was scanned for diagnostic trouble codes and none were found. This failure creates a serious safety concern because the vehicle may unexpectedly be unable to accelerate when merging, crossing traffic, or otherwise attempting to avoid a collision.”
