Defect
The pre-collision safety system uses millimeter-wave radar for obstacle detection. The obstacle detection software is inadequate and may, in rare cases, misidentify scattered radar reflections as a forward obstacle when no collision risk is present. This causes the automatic brake system to activate unexpectedly, resulting in sudden unintended braking.
Corrective action
Reprogram the obstacle detection software in the affected control unit on all vehicles.
