Consumer Description

I was driving about 65 mph on the highway with my Tesla 2021 Model “Y” in “Traffic-Aware Cruise Control” (not Auto Pilot) when, for no apparent reason, the car decelerated rapidly. This happened four times during a 1 hour trip from Boston to New Hampshire. No accidents occurred due to this incident but it was very concerning. This is not a new problem but it is occurring more often since the software was updated to include “Tesla Vision” instead of radar. I did not report this to Tesla because they are already aware of “Phantom Braking” issues with my model.
