Phantom breaking in Autopilot (Model 3 2021)

[Ferik]

I drove to Boston from the Cape tonight, in the dark. Cruise control but no AutoSteer. Every time a car came close behind me, it brakes checks them.

And when a car in front of me turns into the exit ramp and I am in the right lane (of 2), it slows down way too much thinking it’s in front of me instead of now in another lane.

is my experience typical? 2021 Model 3

Your second scenario is common. It takes a while for TACC/AP to "let go" of a car moving out of a lane. I usually just tap the accelerator to override. Haven't experienced the brake-checking.

I have 18,000 miles on my 2021 M3LR and never had brake checking. And this is the first I have heard it on here but anything is possible...

As novox77 said, just press the accelerator and go on. I simply drive with my foot resting on the pedal except when other vehicles are around then I know it won't phantom brake.

Yes, it’s common…
Very common.

I have lots phantom brake issues. 22LR3. Before it's an aggressive slow down 20 mph. Now it panic brakes squealing the tires. This is in cruise or autopilot with clear road no cars.
