Since the first winter after I purchased my vehicle in 2021, typically when cold, but not always, I lose all the Honda Sensing (Advanced Driver Assist Features). The dashboard lights up with the following warnings . — Collision Mitigation Braking System Problem. See Dealer — Road Departure Mitigation System Problem. See Dealer — Auto High Beam Problem. See Dealer — Adaptive Cruise Control System Problem. See Dealer — Lane Keep Assist System Problem. See Dealer This failure of these safety systems can last anywhere from 5-60 minutes. Sometimes if you shut the vehicle off and turn it back on again, the warning will go away. On multiple cold mornings (below ~45°F), my 2021 Accord Hybrid displays a cascade of safety system failure warnings upon startup. The dash shows errors for the collision mitigation braking, lane keeping assist, adaptive cruise control, road departure mitigation, and more—all at once. When these systems are disabled, it severely compromises safety. This issue happens repeatedly in colder weather. The dealer has personally witnessed the issue in their service bay and acknowledged it’s a known problem but had no fix, advising me to turn the car off and on again. This recurring failure of critical safety systems in cold conditions puts me, my passengers, and other road users at risk.
