NHTSA Complaint #11707270 — 2019 HONDA HR-V

Vehicle experienced critical ignition system failure while parked - the engine would not turn off despite repeated attempts over 20 minutes. The vehicle has a communication failure between the ignition switch and the Body Control Module/Keyless Access Unit, creating a stuck electronic latch circuit (B12D3 latch error). This is consistent with Honda TSB 20-116. The keyless start system warning appeared on the dashboard. Unable to shut down the vehicle through normal means, I was forced to manually pull the fuel pump fuse from the fuse box and then disconnect the battery while the engine was still running. This created an extremely dangerous situation requiring me to work in the engine compartment with live electrical systems. The vehicle lacks proper failsafe shutdown mechanisms. This communication failure and stuck ignition circuit poses serious safety risks including fire hazard, carbon monoxide poisoning if in enclosed space, and electrical system damage. No officially stated emergency stop solutions had worked for this vehicle included the triple press and long press.
