I've read a lot of posts about phantom braking but it never really concerned me much because up until today I had only experience minor and infrequent events.
Tonight, however, my car really scared me. It slammed on the brakes to the point that the wheels locked up slightly and the car fishtailed a bit to the left. I was not using either cruise control or Autosteer at the time. Just plain old fashioned driving by hand at 35 mph. It was dark, and a pickup truck was approaching in the opposite lane of a hilly two-lane country highway. We were on a straight portion of the road both heading down toward a low point, and just as the truck passed my Model Y slammed on the brakes and the system started beeping and screaming it's very loud alarm signal. Also an indication popped up on the screen that Dashcam footage was being saved.
Fortunately I was driving slowly and it was easy to regain control, but what the heck?!! That was bad! I assume it was the collision avoidance system that was responsible since TACC and AP were not in use. I believe I have only experience phantom braking when AP was active in the past so this seemed unusual. And I have never experienced braking this hard. Is this normal?
Since I know the exact timestamp and have dashcam footage do you think I should contact Tesla? I've watched the footage a few times and there is absolutely no reason I can see that collision avoidance should have been activated.
