Driver-assist false activation and lightingminor
Two carry-over gen-2 notes appear at low frequency: occasional false Smart Brake Support / forward-collision activation, and headlight or daytime-running-light complaints (no gen-2 lighting recall exists). Test the automatic braking, adaptive cruise, and lane assist on the drive, and verify both headlights and DRLs work.
