Defect
The electronic stability control (ESC) controller contains an error in the braking control program used during Adaptive Cruise Control (ACC) operation. When deceleration is required—such as when closing on a preceding vehicle—the ESC braking intervention does not activate, preventing the system from reducing vehicle speed as commanded. In the worst case, the vehicle may collide with the vehicle ahead.
Corrective action
Notify owners not to use the ACC function. On all vehicles, reprogram the ESC controller with the corrected software.
