Ya Ya I know, bring it to the dealer. I will, just wondering if this has happened to anyone else. It doesn't do it constantly, only in the morning when I leave for work. If I press the traction control button (which turns it off) and then press it again, it stops. My car is clean so it's not being blocked by anything. It's strange it only seems to do it in the morning. Has never happened any other time of the day

 

My 2019 Platinum with 26000 miles has done this when I go through a steep railroad underpass going eastbound at less than 20 mph. This occurs intermittently in mid-mornings.
The road on this underpass has a fairly steep drop. The collision warning engages for a split second then stops as I continue through. One other thought. This happens on bright sunny days. The total number of times this has happened is about 15 events over 2 years. (Same spot, same underpass)

 

Thanks for the reply. That's interesting. This is happening to me first thing in the morning (530am). It's not completely dark but not light either. It'll stop after some time, but still will have the dealer take a look
