Defect
The fault-detection software in the electric power steering controller is incorrect. When battery voltage is low at engine start or at restart following an idling stop, the controller may falsely detect a fault. This causes a warning light to illuminate and disables the steering assist function, increasing steering effort.
Corrective action
On all vehicles, reprogram the electric power steering controller with the corrected software, or replace the electric power steering controller with the corrected part.
