Incident: May 7, 2026 · Filed: July 16, 2026

VEHICLE SAFETY HAZARD: ACTIVE HIGH-VOLTAGE ISOLATION FAULT (DTC P0AA6) WITH DECEPTIVE DEALER/MANUFACTURER BYPASS & CONCEALMENT. On April 15, 2026, the dealer scanned my 2021 Ioniq EV and uncovered DTC P0AA6 (Hybrid/EV Battery Voltage System Isolation Fault), which denotes a catastrophic high-voltage leak into the chassis. This is a severe safety hazard posing immediate risks of fatal electrocution to occupants, EV battery thermal runaway (fire), or sudden total loss of propulsion at highway speeds. Instead of grounding this dangerous vehicle, the dealership concealed the diagnostic code, withheld the physical invoice, and released the vehicle back to me on April 28, falsely claiming it was "fixed to 100%." They forced me to drive an actively compromised high-voltage system. On May 7, the defect immediately returned while driving. I confronted the dealer on May 8 for merely resetting the car's computer to bypass the safety warning, which is an extremely dangerous fire hazard. The manufacturer has refused to replace the defective EV battery under warranty, or provide alternative transportation. This vehicle has now been grounded and decaying in an open lot for over 95 days. This is a severe systemic manufacturing defect and fraudulent maintenance practice that requires an immediate NHTSA safety investigation.
