ADAS/Highway Driving Assist phantom braking and false forward-collision alerts (per active NHTSA complaints on this exact model year)
How to catch it: During your test drive, specifically run it on the highway with adaptive cruise/HDA engaged for 15+ minutes and watch for unexplained braking; if it happens, do not accept delivery without a documented fix.
