The driver of a 2026 Toyota Camry Hybrid experienced a serious safety event involving both the seatbelt restraint system and vehicle speed control systems. While operating the vehicle, the driver-side seatbelt allegedly disengaged/unlatched unexpectedly. The driver was properly restrained prior to the incident and did not intentionally release the seatbelt. The disengagement occurred immediately before or during a single-vehicle crash. During the crash sequence, airbags deployed. However, it appeared that the vehicle continued to move forward under cruise control or sustained throttle input even after airbag deployment.
