- Tesla Phantom Braking "Fix" (adjustment?) ?
A user setting may mitigate the phantom braking drama?
Or, taking the risk, change a setting to stop all emergency braking?
"Use At Your Own Risk!"
Phantom Braking can and often is a horrible experience.
It's an Auto Pilot Horror Show for many people.
I've had my heart rate go up and after three events on a highway, I found myself swearing at the car, then finally shutting off all Auto Pilot.
I have a 2022 Tesla Model 3 Performance. I believe this will apply to all Teslas with similar hardware and software, but I'm not certain.
Can the driver make any setting changes?
I found two setting changes that may make a difference. One setting change was told to me by Tesla experts. While the other is just a complete shut off of all emergency braking. That I have not done myself because I feel safer with Emergency Braking turned on. So I cannot recommend turning it off. Yet, I've seen others begging Tesla for a cruise control only, with no emergency braking. That seems to do it to me.
Again
Use at Your Own Risk
I'm just relaying what Tesla told me and reviewing settings on the screen. DO NOT take this as advice. I am not an expert and am not advising you.
Please submit comments.
I want to know your experience with Phantom Braking and what you are doing about it.
UPDATE:
It seems with each subsequent software update, things improve. I'm not really certain if phantom braking is better but it definitely isn't alarming as much for my holding the wheel in autopilot!!!!!
Hip hip hurray!
Thank you,

I don’t know why more people are not talking about phantom braking. It’s an absolute nightmare. Not once has my auto emergency brake activated for a legitimate reason. It has almost gotten me rear ended on the freeway (had I not hit the gas swiftly). I am baffled that I don’t have the option of shutting it off permanently.
It seemed to get better with software updates. Call Tesla essence if you don't have the latest update.
My 2021 LR model Y has smoother regen when the setting is on "early."
Use at Your Own Risk!
I have a '22 M3P. Love the car but the Phantom Braking is potentially a real deal killer. And with a report I read a real driver killer!
Unless we can fix the problem, it's a serious problem.
"Fix" here is used loosely.
Keep in mind that we don't know if and when the company will be able to permanently fix Phantom Braking.
A Phantom Braking fix for us drivers can be in any or all of the following categories:
- Once we understand how and why it occurs, we take appropriate actions to prevent the impact upon us and upon our safety.
- We can adjust our driving
- We can adjust when we do or do not use all aspects of auto pilot
- We make what few adjustments we dare to the user interface at the screen under the heading auto pilot.
I report here my experience and a potential driver change to the autopilot settings that "might" reduce the degree of braking and the resulting shock to the driver.
I had my first long drive a week after having got this car brand new 18 February '22.
I've seen others seriously report selling a Model Y because they could not take the “Phantom Braking” Fortunately they didn't lose any money but won't go back to buying another Tesla.
My experience with my brand new Tesla.
My car is a 2022 Model 3 Performance.
I believe all I say will apply to all similar hardware and software.
What is Phantom Braking?
- At various and seemingly random times, the car “slams on the brakes”.
- It's really awful and sent my adrenaline up and heart racing!
It has been very upsetting!
- Slamming on the accelerator so I don't get rear-ended just adds to the herky jerky wild ride when all I want is a peaceful ride.
- I couldn't find a reason in these Phantom Braking cases.
There's other sub types of Phantom Braking:
- It also over corrected and braked often “too late”, as the obstacle was already fully out of the way. -It also braked hard when a pedestrian was on a sidewalk, yet non threatening.
But I did see somewhat of a pattern for Phantom Braking.
On a particular 2 lane highway, that is known to be dangerous. There was a backup of traffic on the opposing side. My side of the highway was wide open. Seemingly randomly, my car “slams on the brakes”. It happened at least 5 times before I pulled over to collect myself. I drove the rest of the way with autopilot fully off.
So, my guess is that it misinterprets the opposing traffic, even when stopped as a potential threat and slams on the brakes.
I complained about it to a mobile service tech.
He suggested a change to a setting.
I complained about it in a chat to Tesla support.
He suggested the opposite change to the setting.
I don't know if the setting helps at all.
It's worth trying.
My understanding is that you can have the car conduct frontal avoidance early, moderate, or late. I don't know which is the best setting and I'm not certain if it is helpful or not. I've had some “Phantom Braking” since and I don't know if I'm “getting used to it” or if the setting helped a bit. Also note that the car seems to reset this setting for every ride. That means if it is to be useful, you must change it on every ride.
To change:
Controls / Auto Pilot / Forward Collision Warning
Setting Choices:
Late / Medium / Early
The Tesla expert recommended to me trying the early setting.
Logic is that the car will slow a bit, but earlier. In that way, not so rapid deceleration.
You can also turn off the automatic emergency braking entirely.
Again, the car will reset it to "on" for every ride.
The risk here is that the car will never brake for you.
I could not make that decision to turn it off. But many say they wish Tesla had an ordinary cruise control to prevent phantom braking. Well this might just be the trick!
Another key in minimizing Phantom Braking
Try to understand what causes it. Once you have a theory, then you can expect it and take appropriate actions to deal with it or minimize the risk of it or minimize the impact when it occurs.
When does it occur most?
- Narrow roads
- Two way highways where the oncoming traffic is immediately across the dividing line
- On coming traffic
- Larger vehicles on coming
- Bridges (underpasses)
- Certain lighting
- Rising and "disappearing" road
- Dirty windshield
- Poor or marginal lighting conditions, such as dusk and dawn, and the angles of the sun to the threats
Try to imagine what the system "sees" and more importantly doesn't see (correctly).
The system only has cameras.
There are 3 looking forward. They are located in front of the rear view mirror. They look through the glass of the windshield.
What might the limitations be?
What might make these cameras see more poorly?
With that understanding we can accommodate better.
- Keep the windshield glass very clean, especially in front of the rear view mirror.
- Don't put anything like stickers there.
- If there is limited vision for you, it's likely to be limited for the cameras as well
- If you are driving with a lot of shadows in morning or afternoon, could be an issue. You might choose to shut it off.
Additionally, and related.
The car is far too fussy about “hands on the wheel”. Even with hands on the wheel 100%, it still barks at me. I find this a crappy part of the driving experience. The older Model S would never be so fussy.
Also, the car will bark and alarm far too often, so I look out the window for the danger. Not seeing anything, I look to the screen and the warning is now gone, too late too read it. Also, the words are quite small. For such a loud and annoying alarm, you'd think you could easily see what the problem is/ was. These “Phantom Warnings” happen quite a bit and seemingly randomly.
Note:
One video seems to think that a newer version of software might have improved phantom braking. I don't have this version yet. Is version 2022.4.5.4 improved? I don't know.
"Mine is significantly better as well during daylight hours. Still pretty bad at night but at least there is progress!"
It is definitely not solved, but might be slightly improved. I don't know.
Thanks
George: Just found this video. Very informative. Any update on your phantom braking, any progress with software updates a year later? TIA.
Yes
Significant improvement after a year of software updates.
The improvements began after about four months of ownership.
It still does it occasionally. It's more rare and less violent.
There's also a slight improvement in speed recovery after avoiding a crossing vehicle but it's still unacceptable.
Additionally, I'm more able to cope.
I wish that Tesla would complete the job and have zero phantom braking events and recover more appropriately after is slows for avoidance.
@@georgeborrelli3134 Appreciate the response. All the best.
What they told you is not true. Mine has been set to early since day one and I still get a lot of phantom braking events. I've had way more of these events since Tesla turned off my radar.
Mine did get better. Like you said, not from any settings. But After many software updates and a wheel alignment at the service center and a few thousand miles. Mine is a 2022. I never had the radar. My thoughts now are that if there's a problem, such as wheel alignment, fix that first. Get the software updates as quickly as possible. Keep the glass over the lenses clean. It should improve in time. I know it's not a very satisfying solution but it seems to be much, much better now.
@@georgeborrelli3134 Not sure what a wheel alignment has to do with reducing phantom braking events. The data proves that there are more of these events without radar, than there was with it. Elon was so wrong.
@@Resist4 You are correct on all counts.
The wheel alignment helped more with lane keeping than phantom braking, at least logically.
Since you had radar, I presume you had a pre 2017 Model S ?
Tesla should make good on this problem!
Mine did get much, much better. Many software updates later.
Are you current with software updates?
I keep pestering Service with all my issues.
I have to sometimes keep a log of when the big issues happen and relay that to the service center. I think they can pull the data and try to figure out what's at play.
@@georgeborrelli3134 I have a 2018 Model 3. I don't get many software updates anymore because I have the FSD beta and Tesla doesn't push out stuff to us much unless there it's mostly for the beta. And this really sucks because I'm still dealing with the Dashcam Unavailable issue and beta users haven't gotten the fix yet.
I can't visit my service center as frequently as you because the closest one to me is 2 hours away. But oddly enough my City is getting a new service center, just don't know how long before it's built.
No music... wow.
Congrats 🥰
Thanks. Yes, some videos it's so annoying.
You have auto pilot on “speed limit” instead of “current speed”. If you pass a speed limit sign it will immediately lower your speed. Change it to current speed. Bet that is causing your issue
Thank you.
But phantom braking events are very different.
