You continue using this feature despite these errors occurring daily? The way you describe it makes autopilot seem like an inexperienced teenage driver; I think whatever marginal safety benefit you get from it might be erased by the life-shortening stress such erratic car behavior must induce.

You cannot turn this behavior off persistently -- you need to open car settings and disable it every time you leave Park. My guess is that some jurisdictions mandate this behavior. When this "feature" triggers you have a short window in which to do _something_ to tell the car that you are paying attention. Your options are either: accellerate or brake. If you do nothing the car may apply full brakes and bring you to a full stop, regardless what is behind you. > Reports of “phantom braking” first surfaced last fall This has been happening for much longer than that -- at least as early as Winter 2019, when I unintentionally brake checked a Prius after merging while going over 101 @ Rengstorf.

  What behavior are you referring to? We are talking about autopilot, and possibly FSD, neither of which are engaged by default (obviously!) What do you mean they can't be turned off? > When this "feature" triggers you have a short window in which to do _something_ to tell the car that you are paying attention. Your options are either: accelerate or brake. If you do nothing the car may apply full brakes and bring you to a full stop, regardless what is behind you. Again, what is this? I have a Tesla, and I'm not aware of any feature that requires me to accelerate or brake to prevent the car from stopping itself.

    > What behavior are you referring to? Automatic Emergency Braking. You cannot turn off AEB persistently. > I'm not aware of any feature that requires me to accelerate or brake to prevent the car from stopping itself Before the car emergency brakes, it will warn you via "Forward Collision Warning"; the screen will show the object it thinks you're about to hit in red. You can set this to "Late" to reduce false positives -- but if you do, you'll have less time to take action yourself. So now I set it to Early. After a FCW, you have a small amount of time to do something before the car will do something for you. The M3 manual describes AEB here: https://www.tesla.com/ownersmanual/model3/en_us/GUID-8EA7EF10-7D27-42AC-A31A-96BCE5BC0A85.html https://www.tesla.com/ownersmanual/model3/en_us/GUID-8EA7EF1... It also explains "Automatic Emergency Braking is always enabled when you start Model 3. To disable it for your current drive, touch Controls > Autopilot > Automatic Emergency Braking."

      This article is about autopilot phantom braking, not AEB. I've never had AEB trigger, or heard of it triggering when it shouldn't, but maybe I'm unaware.

        Phantom braking includes self-driving/cruise and ADAS, e.g. "What is phantom braking" > Phantom braking is a term used to describe when an advanced driver assistance system (ADAS) – or a self-driving system – applies the brakes for no good reason (AEB is part of ADAS)

        i had it trigger twice: once to prevent a frontal crash that would have been my fault, and once during a storm. i am very glad that it is there; works extremely well.

  Can you put some tape over the sensors?

Can't speak for OP, but I'm supposed to be paying attention at all times while autopilot is enabled; as soon as I feel the vehicle may phantom brake, I apply more pressure to the accelerator to maintain speed. I believe the NHTSA is going to require Tesla retrofit radar on all vehicles to mitigate their Tesla Vision functionality deficiency. (submitted lengthy dash cam videos and accelerometer data to the NHTSA as a complaint)

  I have an early release Model 3 with radar. I suspect they stopped using the radar in a software update once they started releasing Model 3s without radar, as it didn't have this jerky stopping behavior before that.

    Happens often on my Y, does not happen on my legacy S and X (circa 2018 and 2019) that are equipped with Continental radar front facing radar. I believe even current S and X vehicles are still getting radar installed, so Tesla is only being cheap on the 3 and Y to keep moving them at volume as a supply chain mitigation.

      Tesla stopped putting radar units in new Model S/X in February this year. https://www.tesla.com/support/transitioning-tesla-vision https://www.tesla.com/support/transitioning-tesla-vision

      vehicles from 2019 being referred to as "legacy" is the most infuriating thing I've read today. Of course no offense to OP, i've heard it referred as such by others and I know it's not literal. But it's maddening to me though that a vehicle that is still under warranty has a moniker that traditionally means end of life/support in software.
