I just updated to the latest firmware on march 19th, 2020... Immediately after that sudden breakings or hard decelerations appears while driving on freeway (on an avg speed of 73 mph) on autopilot or even on TACC.
Worse is it doesn't happens once in awhile... It happens maybe EVERY 2-3 minutes driving.
"Hard deceleration" means it goes from 73 mph down to about 50 mph in just maybe 5-7 seconds. And then gradually goes back up to 73 mph in about 10-15 seconds.
