NHTSA Complaint #11709314 — 2024 KIA NIRO

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.
