Summary of Incident On February 21, 2026, a Level 2 charging event resulted in a catastrophic electrical failure involving my vehicle and the associated EV charging equipment. The incident caused: Severe damage to the EV charging connector (pigtail and receptacle) Destruction of my home inverter system Sustained electrical arcing between L1 and L2 conductors Loss of primary electrical service to my home The vehicle was actively charging at the time of the incident. Safety Concern The failure presents a significant safety risk, including: Potential for fire due to sustained electrical arcing Possible high-voltage backfeed from the vehicle’s onboard charger (OBC) onto the AC input lines Failure of protective devices (surge suppression components destroyed) Risk of similar incidents occurring in other vehicles The damage pattern suggests a high-energy electrical fault localized between L1 and L2 without ground involvement. Current Status Vehicle has been out of service since February 21, 2026 Subaru has had possession of the vehicle since February 24, 2026 No determination or repair has been provided after several weeks Requested Action I request that NHTSA: Investigate potential onboard charger (OBC) failure modes Evaluate risk of electrical backfeed or uncontrolled fault conditions during charging Determine whether this represents a broader safety defect affecting other vehicles
