Vehicle Information: 2026 Honda CR-V Sport HybridComponent: Power Train / Hydraulic Brakes / Electronic Stability ControlDescription of Incident:On [Date], my 2026 Honda CR-V Sport Hybrid was parked facing uphill on a steep incline. I started the vehicle, depressed the brake pedal, released the electronic parking brake, and shifted into Drive. Upon transitioning to the accelerator, the vehicle failed to hold its position. It immediately and rapidly rolled backward down the incline, completely overriding the Hill Start Assist (HSA) mechanism. Despite accelerator input, the hybrid powertrain failed to deliver the instantaneous forward torque required to counter gravity. The vehicle gained rearward momentum and collided with a closed gate.Safety Justification:This un-commanded rollback presents a severe, systemic safety hazard. Research into hybrid consumer data reveals a documented pattern of drivers being blindsided by the lack of traditional automatic transmission "idle-creep" torque on inclines, combined with counter-intuitive electronic HSA deactivation thresholds. The vehicle’s software logic fails to safely manage dual-pedal inputs during hill starts, creating an unreasonable risk of rollback collisions.
