2021 HONDA ACCORD HYBRID Forward Collision Avoidance Warnings Problems

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...

My daughter was driving the vehicle on the highway, probably 65 mph. she said that a sheet shaped piece of metal struck the front bumper. It is not clear if this was on the road or fell from the car. It seems to have happened fast. the vehicle sustained no obvious body damage but the frame and bracket holding the milliwave radar module were damaged. The milliwave module was intact. the cover for the milliware radar module was missing. This car has not been in a collision. The dealer wants over $2,000 to replace all the components including the milliwave radar. They say it is probably broken. If the existing module is reinstalled, they say it may not work. I was not able to download the estimate for repair. Does this happen often or is there a design defect?

I was driving north on 95 in Massachusetts going about 75 mph and the forward collision avoidance went off (flashing break waring in the dashboard) slowing my car down to under 50 mph. There were NO vehicles or obstacles in front of me. This keeps happening and it's only a matter of time until I get rear-ended. I reported this to Honda and they said it's just the safety features.... I had one person at Honda admit this was a know issue in the service departments but American Honda isn't acknowledging this as a know issue or problem. There is NO way this should be happening- it's dangerous.

I was driving on the highway going about 70mph and the automatic brake/ collision prevention went off and tried to stop my car for seemingly no reason. There were no cars or objects in front of me. The orange break alert flashed in the dash and car slowed abruptly. Thankfully no one was behind me. The only thing I can think of was the shadows on the road. This is the third time an event like this has happened to me. I made the dealership aware this happened after the second time and I was told i just wasn't use to the safety features. I have owned this car for a year now and am beyond use to the safety features, this is flat out unsafe and seriously concerns me. I do really like this car otherwise but I drive a lot for work and if it happens again, I...
