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
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 Cond
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.
