We like many things about our model Y. But Not the autosteer or autopilot (TACC). Will try autopilot from time to time but still phantom braking does happen on the latest release.
There is no obvious pattern, except this: my wife is napping in the passenger seat, I'm driving on the freeway with autopilot, no cars nearby, the car suddenly and abruptly slows down even brakes suddenly.. She wakes up and says WHAT DID YOU DO? I answer defensively NOTHING THE CAR DID IT ON ITS OWN! And I proceed to turn Off autopilot. I guess it's something about the cameras, glare from the sun, reflections etc. Anyway no use in guessing why, it's Tesla issue to solve. .
