Issue
In hybrid vehicles, the brake actuator control computer contains a program with insufficient consideration of control logic, which may prevent brake hydraulic pressure from being properly adjusted during braking in a turn. As a result, the intended braking force may be temporarily unavailable, and stopping distance may be longer than expected.
Corrective action
On all vehicles, update the brake actuator control computer program to the corrected specification.
