If the vehicle is not properly parked with thetransmission in the correct position, and if the vehicle is parked on a grade, reduction in parking brake force could lead to unintentional rollaway and anaccident.
The design of the parking brake grip makes it possible to distort the grip and pinch the brake release knob. If the release knob sticks in a partial engage/release position because of the pinched grip, it is possible for the lever to release unintentionally with a corresponding reduction in parking brake force.
