Will on-star record brake operations prior to crash?

OnStar systems typically record data related to vehicle performance, including brake operations, in the moments leading up to a crash. This information can be part of the event data recorder (EDR) capabilities, which capture critical vehicle metrics before and during a collision. However, the extent of data recorded may vary based on the vehicle model and the specific OnStar services activated. For detailed information, it's best to consult the vehicle's user manual or contact OnStar directly.
