NHTSA complaint #11735098

Owner complaint summary

On April 25, 2026, while the vehicle was stopped at a red light on [XXX] , the vehicle suddenly became inoperable and displayed multiple warning messages and warning lights. The warning messages included “Brake System Problem” and “Auto Idle Stop System Problem.” Additional ABS/VSA, battery/electrical, and system warning lights were also displayed. The vehicle was occupied at the time, including children, and this created a serious safety concern on a major roadway because the vehicle could not be driven or safely moved under its own power. Police responded to the scene, Honda Roadside Assistance was contacted, and the vehicle was towed to an authorized Honda dealer. The suspected affected systems include the brake system, electrical system, battery/charging system, ABS/VSA system, Auto Idle Stop system, and related control modules. The vehicle is currently available for inspection at an authorized Honda dealer. The issue has not yet been fully diagnosed or confirmed by the dealer. The dealer advised that the battery may need to be replaced before diagnosis can continue. However, the battery may have discharged because the vehicle remained in a fault state with warning lights/system alerts active after the original brake/electrical failure. Therefore, the dead battery may be a consequence of the original failure, not necessarily the root cause. There were no known prior warning signs before this incident. The warning messages and lamps appeared at the time of the failure. A full diagnosis is pending. I am concerned that this brake/electrical/system failure could happen again while driving or stopped in traffic and create a safety risk.
