Issue
In the driver assistance system, the forward obstacle pre-collision mitigation control program is incorrectly calibrated, causing the system to misidentify highway tunnel lighting as a forward moving object. When this occurs, a proximity warning tone sounds and the brake may momentarily activate.
Corrective action
On all vehicles, update the driver assistance control program to a corrected/updated software specification.
