Description
At low ambient temperature, with the parking brake applied abd the engine running, pressure can build up sufficiently to partially pressurize the brake chamber which controls the ddm park brake at the rear of the transmission allowing the parking brake to partially release.

If the vehicle is parked on a moderate incline, the vehicle can roll away without warning and possibly result in an accident.
Corrective Action
Dealers will re-plumb the hydraulic lines of the hydraulic park brake system preventing unintentional release of the park brake.
