Issue
On vehicles equipped with the idling stop (i-Stop) system, the electric power steering control unit contains a software error. After the engine automatically restarts from an idling stop state, the power steering function may rarely fail to activate, increasing steering effort required by the driver.

On all vehicles, reprogram the electric power steering control unit. Alternatively, replace the control unit with a corrected/revised part.
