And there's different flavors of "phantom braking". Let's give them classes: Class A is a full-on emergency stop. Somehow, the car has the idea that there's an elephant straight ahead. In this Class, the car's wheels aren't screeching, but that's only because Tesla's have anti-lock brakes.Just to add to the clamor. We experienced three closely spaced incidents of phantom braking with our Model Y while using cruise control without lane assist on highway 395 between Lone Pine and Bishop, California on Saturday 25 June. We've had the car since January 2022, and this was a (shocking) first. Haven't dared to use cruise control since. We have since updated to software version 2022.16.2. I guess we'll have to see if this took care of it. This is my first big disappointment with Tesla. My second is that it is impossible to find a way to report the issue to Tesla itself (other than the bug report which should be done on the spot). I have filed a report with NHTSA. Until the issue is fixed -- and from what I can tell, Tesla never really does fix phantom braking -- I wonder if it can be prevented by turning off emergency braking when using cruise control...?
Class B is a bit of a slow-down, say, from 65 mph to 60 mph. It's noticeable, not wonderful, but, unless one is being tailgated, not dangerous. At least in the sense that one does have the time to react and hit the gas without other traffic getting seriously freaked out.
The car over here is a 2018 M3 LR. Never have had a Class A. Class B's were a lot more common in 2018 and, over time and software updates, have become a lot less common. The trigger is usually a shadow across the highway, and that includes from trees and overpasses. The Class B events seem not to have been affected one way or the other by the use or lack thereof of the car's RADAR system.
So, was they near-screech, high-G halt attempts? Or a less dramatic but unnerving slow-down?
