New electric vehicles rely heavily on accurate range calculations and stable charging systems to function as advertised. When those systems are unreliable, even short daily drives can become unpredictable. That is what happened with this 2025 Kia Niro EV, which began showing battery performance and charging issues almost immediately after purchase.
At just over 1,000 miles, the owner returned to the dealership after noticing that the battery appeared to be draining far faster than expected. Diagnostic testing revealed a fault within the vehicle’s charging management system, specifically tied to the EVSE and vehicle charge management unit. Technicians replaced the faulty component, reset the system’s state of charge and health, and returned the vehicle after several days in the shop.
Despite that repair, the concerns did not go away. Less than a month later, the owner brought the Niro EV back, reporting significantly reduced driving range even under normal driving conditions. The owner stated that charging habits were conservative and that accessories like air conditioning were used minimally, yet the vehicle consistently delivered substantially less range than expected. Although technicians were unable to duplicate the issue during that visit, the complaint remained unresolved.
By June 2025, the problem became more pronounced. The owner documented a dramatic and sudden drop in battery percentage during normal driving, with the vehicle losing nearly all charge over a relatively short distance. This time, technicians were able to duplicate the concern. Diagnostic scans again identified faults within the same charging management system, triggering a check engine light. The vehicle control module was replaced once more, and the system was reset and tested before being returned.
Even after that repair, the owner continued to express concerns about inaccurate range reporting and battery performance. The vehicle returned yet again with complaints that the displayed mileage did not align with actual driving range, particularly as the battery percentage declined.
The Niro EV experienced recurring charging system failures, repeated replacement of critical electronic components, and ongoing battery range complaints shortly after purchase. For an electric vehicle, defects affecting charging accuracy and usable range directly interfere with the vehicle’s core purpose. When a new vehicle undergoes multiple repair attempts for the same system or continues to exhibit unresolved defects early in ownership, consumers may have rights under state lemon laws.
