Narrative

On February 9, 2026, our 2023 Mazda CX‑9 experienced a sudden and complete system malfunction while being driven. Multiple system failures began approximately six minutes before the crash. During this time, the driver reported: • Total loss of steering • Complete brake failure • No response to acceleration or driver input • No ability to slow, stop, or maneuver the vehicle • No meaningful warnings that allowed corrective action The vehicle became completely uncontrollable. At the crash site, there were no skid marks, no braking evidence, and no signs of evasive action, consistent with a full loss of vehicle control. The vehicle only stopped after entering approximately two feet of water and striking a tree. The vehicle was declared a total loss. This incident represents a severe safety defect involving critical electronic and mechanical systems. A modern vehicle should not lose all steering, braking, and control functions under any circumstances. We are requesting a full investigation into the cause of this failure and whether similar incidents have occurred in other Mazda vehicles. We can provide photos, crash documentation, diagnostic information, and driver statements upon request.
