This thread is for discussing this particular version of Tesla's FSD.
It is for cars with HW3. Approximate release dates of the versions have been:
12.6 - December 30, 2024
12.6.1 - January 10, 2025
12.6.2 - January 22, 2025
12.6.3 - January 31, 2025
12.6.4 - February 17, 2025
-----------------------------------------------------------------------------

I will be very interested in a report of how FSD 12.6.1 performs on HW3.

The few reviews I've seen on X have been overall very positive.

None of them have been from the normal, high-profile Tesla shills, but they still may be Tesla shills.

While FSD 12.5.4.2 has been useful enough to be worth $99/month to me, I'm ready for some improvement - particularly after this episode yesterday where I was behind another vehicle that had come to a stop in front of me. Suddenly, my car started moving forward and I quickly stepped on the brake pedal, which was very firm. Instead of the vehicle stopping, it started moving backward! I pressed on the pedal as hard as I could and the car stopped and shifted itself to park. That event was a bit unsettling - I'm glad the car behind me wasn't any closer.

What version is best in your opinion? All that have experience reply. 12.5.4.2, 12.6.1, 12.6.2, or 12.6.3, I am curious if there is a pattern.

 

Moderator note: This was originally in the 2024.45.* software thread and pertains to 2024.45.32.5 (FSD 12.6.2).

Drove 70 miles last night and found:

• Minimize lane changes is embedded in driver profile("Chill", "Standard", and "Hurry".)
  • Still need to test "Chill" and "Hurry"
• Ignores speed limit signs to follow a mystery map with defective speed zones.
  • "Phantom brake" events are now "phantom speed zones."
  • Construction zone speed signs often ignored.
• Higher map resolutions shows businesses and destination names.
• Speed control is "less bad" but still needs some accelerator inputs
• Passenger side air flow can be directed to driver side instead of splitting horizontal
• Steering city streets using turn signal is easier.
• Half entered a dashed lane that was coming to an end but went back early enough as it narrowed.

Better but still a work in progress.

I was early recipient of 2024.45.25.15, which is FSD 12.6.1 on my 2020 Model Y with HW3. Here are my first impressions:

First Drive: I can see the potential here. Made an unprotected left (no traffic at the time) that other versions have basically been unable to complete. More natural feeling acceleration and braking. Prior versions of FSD I averaged 3 disconnects on my 10 mile commute to work. This version only twice. Tesla ”recommends” setting max speed at 40% over the speed limit, which is ridiculous in my opinion. Around here, cops stop you at 5 miles over. At 65 mph, 40% is 26 mph over. FSD still blissfully ignores speed limit reductions and happy drives 55 in a 40 mph speed zone unless I disengage to slow it down.

Second Drive: DISASTER. Unable to engage FSD due to “autopilot cameras unavailable” error message. There are two phantom cars on the FSD visualization. One exactly in my left blind spot. A second about 20 feet ahead and 100 feet left of my car. These phantom cars perfectly mimic my car, like the Blue Angels flying in formation. No big deal I think, I’ll just drive home manually. Until I needed to turn left. Automatic collision avoidance activated, and tried to swerve me back into my lane when I tried to turn left. I was able to overpower. But lots of alarms and steering corrections applied. Two finger reset didn’t fix it. But next morning was working again. Cameras were clean. It was dark out, but no other road or vision obscuring condition. I put in a ticket with Tesla on this, and they quoted me $740 to “fix” this problem. This problem was caused by a defective software update. It hasn’t happened before. If I asked Tesla to install a new piece of hardware on my car, I would of course expect to pay for that. If that hardware broke 24 hours later due to a defect, I would expect them to fix it at no cost. Asking owners to pay for a software defect to be ”repaired” is ridiculous in my opinion. And even though this car is really a “computer on wheels”, we have no real way to report software defects to Tesla. I couldn’t use the “report autopilot disconnect” feature because autopilot wasn’t engaged at the time. Tesla Service seems clueless about software issues when you report them. Why don’t we have a direct line to report software defects the way that most “beta” programs do? And yes… I know Tesla no longer calls this software “beta”, they call it “Supervised”. But it is still VERY much beta software in my experience.

Since then, I’ve been watching it like a hawk, and like all prior “upgrades” there is some good, some bad. Overall yet another incremental improvement, but not the “leap forward” Tesla has been marketing.

Good:

• More “human” like in its acceleration, deceleration, and general driving behavior. I was amazed when I was in a long line of traffic at a stop light and there were cars in the other lane trying to turn left in front of me onto a side road. FSD waited short of the crossing intersection to let the other cars cross. Something I have NEVER seen before and very much “human” judgement.
• Improved anticipation of lanes. Prior versions, you would be in the right lane with a right turn 100 yards ahead, and FSD would try and change lanes to the left. That seems to be improved in this. It will stay in the appropriate turn lane now.
• Unprotected left on a 4-lane rural highway with a center turn lane. Prior versions almost never completed this turn if there was any traffic at all. This version can do it some of the time, and is much more natural. Still won’t turn into the center “turn lane” then merge into the travel lane. But definitely better.

Bad:

• Still blissfully ignores speed limit reductions and blows right through them. I believe this was a prior cause for a NHTSA recall on the FSD software.
• The behavior of hugging edge of lane is back. Doesn’t do it all the time. But it isn’t staying centered in the lane as well as prior versions did. I’ve been honked at multiple times when it drifts right up the the lane line and too close to traffic in next lane.
• Lackadaisical lane changes. When you are in FSD and turn on your turn signal, it often hesitates, then is very hesitant making the lane change.
• Phantom braking still a problem. Random braking at highway speeds for no apparent reasons.

Just my experience so far. We are still a long, long, long way from “robotaxis” in my opinion.

 

Jerky steering in left turns are somewhat smoother. Still a couple of small jerks but much improved.

Summon nicer. Need to test in rain.

Tesla ”recommends” setting max speed at 40% over the speed limit, which is ridiculous in my opinion

I believe this recommendation is based on their desire to let the car make all the choices. 40% over the speed limit is really just setting the user input out of the way. And I don’t use their recommendation. I have been setting it at 5% or 10%, but then often actively change the max speed with the scroll wheel.

happy drives 55 in a 40 mph speed zone unless I disengage to slow it down

Try just scrolling down the max speed. I don’t have FSD 12.6* yet on my HW3 cars, but I am expecting they have added this capability the same as HW4 when they introduced the chill/standard/hurry driver profiles.

…
Try just scrolling down the max speed.

Yes, I can confirm that the current version of FSD Beta does indeed allow the user to “dial down” the max speed. But the point is, I shouldn’t have to. FSD is a long way from “robotaxis”. I believe Elon promised that our cars would be full self driving robotaxis “within the year” way back in 2016 (correct me if I’m wrong about the date). Here we are nearly a decade later in 2025, and the car is still ignoring speed reductions and ”recommending” that it be allowed to go 40% over the posted speed limit. Both rolling stops and ignoring speed limits were the subject of prior NHTSA recalls I believe. Both fixed by Tesla with a software update. So that is good that Tesla can fix most of this with software, which other manufacturers haven’t been able to do. But why are they reintroducing bad behavior that was the subject of a recall with this update? Elon has said this version of FSD is “6x better” than last version. That isn’t my experience at all. A little better? Sure. Hopeful progress? I agree. 6x better? Not even close IMHO. Remains to be seen if NHTSA will do anything about this, assuming they even survive the “DOGE“ era.

 

I believe Elon promised that our cars would be full self driving robotaxis “within the year” way back in 2016 (correct me if I’m wrong about the date).

I don't think he specified a year on any specific planet. A year on Neptune is ~165 years on Earth.

 

Looks like the survey needs an update:

I was planning to share a very pleasant, FSD drive only to find a new release is downloading. Since I'm here:

• Driver profile setting - seems to flip between the right scroll wheel left-right and the Autopilot screen. Discovered while trying to change the radio station, I like the scroll wheel better because up-down adjusts the maximum speed.
• Auto-speed - sets the maximum higher than I prefer BUT it didn't go overboard. Easy enough to use the scroll wheel to moderate the maximum speed.
• Reverse curves - no longer clips the apex by crossing the center lane divider. It comes close but very accurately stays in the lane. It also handles speed control very smoothly.

I also realized that "Add" to a navigation route is actually "Insert". We really need:

• Insert - puts a way point immediately next like today's "Add"
• Add (before destination) - tack new way points just before the destination
• Extend - changes the destination while keeping the existing route.

I have been reading about significant regressions on FSD 12.6.2 from 12.6.1 from some of the OGs on X.

12.6.2 is included in 2024.45.32.6 for HW3 vehicles.

 

Yes, I can confirm that the current version of FSD Beta does indeed allow the user to “dial down” the max speed. But the point is, I shouldn’t have to.

I somewhat understand what your complain is, but I also understand where Tesla is coming from.
If Tesla would have implemented 5% over instead of 40% the posted speed limit, I am sure you'd be complaining why this low, right ? What Tesla did great is that it allowed the driver to set the offset he wants. I am using 15% offset speed limit instead of 40% because 40% is too high in certain zones of my commute. And I am using this setting based on the km/h speeds, not mph, and it works pretty much perfect. In 30 km/h speeds my car is doing 34 km/h (you get a speed ticket at 10 km/h over). If Tesla would have let the use of a number instead of a % for the offset, that would have been marvelous for low speeds, but not so much for high speeds. It is a tradeoff that Tesla did and I am fine with it.
And people should not forget, Tesla is using the registrations of the traffic flow on a road and trying to chose the optimal speed so that they don't become nuisance. And from my experience, Tesla is doing a great job in this regard.

 

If you go into Edit Trip, there is an Add option there. It is the equivalent of your Extend, putting the new destination at the end. As for additional waypoints within the existing route, you can always move them around within the Edit Trip after having added them through “Add Stop” or “Add”.

I'll retested "Add" and sure enough, it inserts the new waypoint between my current location and the previous way point. This can only be put in the correct location by using "Edit" ... but not so slowly FSD gives a strike.

More testing:

• Hurry mode - shows either on the screen upper left near the speed above 50 mph. Below 50 mph, on the AutoPilot screen.
• AutoSpeed very much improved.
• "Phantom Speed Zone," unposted to 15 mph, drove through at 35 mph! YEA!!!
• Reported two "passed U-turn exits."

Bob Wilson

 

Success, "phantom braking" is dead. Using "Hurry" driver profile, both of my repeatable, phantom brake locations are gone. It still shows the bogus speed zone on the screen but the car just keeps going at the speed it entered.

My car (MY from March 2020) got 2025.2 on 01/29. That same day I paid the extra to go from EAP to FSD. Everywhere I read there's no FSD with 2025.2.

However, I now have v12.5.4.2 FSD along with 2025.2.

Standing by for FSD 12.6.x

 

I think people sometimes assume there is no FSD with a version when Teslafi is slow to update their data with the corresponding FSD version. Here is an example from this morning where the 2 newest releases don’t have the corresponding FSD version identified.

But now Teslafi has it updated.

 

This week-end I got FSD v12.6.3 (2024.45.32.10) on my HW3 model 3. It came from FSD v12.5.4.2. This is its first implementation of the Chill/Standard/Hurry profiles and the different user speed controls since v12 first came out. I have had these options on my HW4 car for over 3 months and have been very anxious to see them in their HW3 manifestation.

I did a 50 mile test drive this afternoon with v12.6.3, and then turned around and did the same drive in my HW4 model S (v13.2.6, also 2024.45.32.10). With both cars I used the Standard profile and max speed set to +10% over the speed limit. The drive included limited access highway, divided highway with traffic lights, and rural 2 lane roads.

The tldr version is that I agree with much of what is being reported, that v12.6 is a huge step forward for HW3. Not surprising, it is not up to the caliber of HW4 v13.2.6.

The best thing is the smoothness of the drive. Both on the main road and during turns, the jerkiness and micro hesitations were gone. Acceleration and stopping are smooth and timed similarly to how I drive. No last minute teeth-clenching stops at stop lights. No pausing at green lights. The main driving and smoothness is very similar to HW4.

The worst thing is that the car never centered itself in the lane. It had a strong bias to the left on straight sections and to the inside of turns. It went over the lines a number of times. These are not problems in the current HW4 version.

I like the speed control settings and the ability to change the max speed with the scroll wheel. I think it is a huge improvement over the auto/manual selection of earlier v12. But there are still plenty of issues with the implementation.

• The Chill/Standard/Hurry profile is only displayed on a limited access highway. When the profile is not displayed, it cannot be changed with the right scroll wheel. On HW4, it is always displayed and you can always change the profile setting with the scroll wheel.
• On a limited access highway, the max speed is always displayed, even if below the max speed. On all other roads, the max speed is only displayed if you are going the max speed. You can briefly see the max speed setting by scrolling the right wheel up or down. HW4 is the same.
• Sometimes, the max speed setting works just as you expect, in my case, 10% over the speed limit. There are times, though, that it totally ignores your setting. One example is on a local 4-lane highway, with a speed limit of 45 mph, the car was going over 60 mph. I checked the max speed setting and it was 65 mph. This is a road section where the traffic typically goes over 60 mph. I'm actually fine with what FSD was doing in this particular case, but it gives me pause that it was going significantly over my settings. This behavior is the same as the current HW4 version.
• I can scroll down the max speed, and the car quickly responded in all my tests. Same for HW4.
• If I am at the max speed and scroll up the max speed, the car doesn't necessarily respond at all. Pretty much the same on HW4.

Some other miscellaneous things.

• There were no random, inappropriate lane changes. It actually erred on the side of staying in the slower lane, making me double-check that I was in Standard, not Chill. HW4 Standard is a bit more aggressive (but still appropriate) with its lane change choices.
• I could turn off automatic wipers while in FSD. I did this after one dry wipe. This is not one of my pet peeve issues, so do not know if maybe they implemented this capability a while ago.
• Once it got in the left turn lane when it needed to get in the right turn lane. This has been a sporadic problem with various versions of FSD, trying to turn the opposite direction as what the navigation shows. I don't know if it would have repeated this at the same intersection. The HW4 test drive got it right.
• It tried to turn right at a red light on a NO TURN ON RED location. HW4 made the same mistake.
• It set the max speed to 42 mph on a rural road that it showed the speed limit as 25 mph. I didn't see any signs and doubt 25 mph was the correct limit. I thought 42 mph was a fine max speed but note the discrepancy if the road was actually 25 mph. HW4 was the same.
• It made a few overly dramatic swerves when on rural roads. One was to avoid a large puddle that was actually off the road, and one was an off-road limb (at least that is my theory for the swerve). HW4 did not do these things, appropriately ignoring things that should be ignored.

 

This week-end I got FSD v12.6.3 (2024.45.32.10) on my HW3 model 3. It came from FSD v12.5.4.2.

Tried it out yesterday and note that it continues to ride on the yellow line on blind curves on my usual two-lane highway ride. Fun to play with occasionally, but this to me is a continuing fatal flaw - and has been for a long time. I report it when it gives me the opportunity but this has obviously been ignored for a long time.

 

Testing driving modes, Calm, Standard, and Hurry, on 2024.45.32.10 in HW3, 2019 Model 3:

• All versions maintain entrance speed to a "phantom speed zone" (previously called a "phantom brake." These bogus zones are so brief that we are often through them before the car responds.
• "Calm" is perfect to stay close to the speed limit with some minor variations on each side.
• "Standard" more like regular traffic ... go with the flow.
• "Hurry" we're going to see more lane changes to get ahead of the traffic.
  • Often use the right thumb wheel as the MAX SPEED can exceed 80 MPH for 'exciting times.'

ps. @Bigriver is this how you want us to share our testing?

 

MS 2021 HW3. 12.6.3. Beta tester x5 years. This is big regression. Driving down middle road, constant slowing and close to stopping. Rebooted and recalibrating cams but doubt that will help. Dangerous enough that for first time would not use till next updaye.

 

I received 12.6.3 on my 2018 M3 with HW3 yesterday. I'll start with a caviat that FSD on Maui normal roads is typically fairly easy. I took a trip from west Maui to North Maui (and back) today. ~30 miles each way. A couple of comments.
1. I disengaged only twice on the way there and none on the way back. First one was tire rubber in the center of the lane and the car over compensated on its avoidence move into the oncoming lane. The second was it got into the left lane just 50 ft before it needed to turn right.
2. Going 45 on a 45 mph curvy road it consistently crossed over the right lane edge onto the rumble strips when going around curves. Annoying.

So overall getting better. Not there yet. There is still a corner near me I don't trust it yet so I always dissengage there and don't count it against FSD. One day when it isn't busy I'll let it try that.

 

There is still a corner near me I don't trust it yet so I always dissengage there

So does it ALWAYS make the same mistakes? I have a place (a merge) where FSD will sometimes get it right and most times does it wrong. About 7 out of 10 times it's wrong, and yet other times it's flawless. As a result, I always disengage there too. I can't figure out what's different the times it gets it right either. Hallucination or something...

[Edit, just got the software update last night, we'll see if it still messes up at the merge...]

 

A few weeks after getting 12.6.1, I got 12.6.3 last night.

On my way to work this morning, 12.6.3 drove more slowly (too slow) in a couple of spots where 12.6.1 would have driven faster (more appropriate). 12.6.3 also failed to turn left into the parking lot off of a 4-lane divided highway. The vehicle signaled, slowed, and began turning, then changed its mind and started to drive too far down, so I had to intervene. 12.6.1 did this successfully.

During this first drive, 12.6.3 seemed even smoother than 12.6.1, which was already acceptably smooth to me, but it got a bit dumber.

Based solely on this first drive (that I take every morning), I would go back to 12.6.1 if I could.

 

Hard to answer because not all of us have gone sequentially through all these version. I jumped from 12.5.x to 12.6 something... I never saw 12.6.1

 

As far as the 12.x versions, I've used 12.3.6, 12.5.4.2, 12.6.1, and 12.6.3.

12.6.1 was by far the best.

I just had my second drive with 12.6.3. It drove 50 mph in a 55-60 MPH zone then 82 in a 75 and kept varying. The steering has a nervous feel - too many micro corrections on the highway trying to keep the vehicle centered in the lane. Made a couple of unnatural turns. Definitely worse than 12.6.1 for me. Still not nearly as bad as 12.5.4.2, though - those frequent hard brakes for green lights and jackrabbit starts were brutal.

 

After a software update, is there any "calibration" needed or done? (Vehicle dynamics are somewhat different on a car with 18 inch versus 19 inch wheels for example). I ask because the very first drive with the latest release was weird. The car was driving ON the double yellow line around tight corners, the twisties up to Los Alamos proper felt very unsettled, etc. It was a lot like me when I get into a car I haven't driven before and I have to get used to the steering, clutch, etc. But a LOT of that is gone now and the car seems to behave pretty much like before. (So far I very much like this latest, some common FSD fails passed with flying colours.)

 

@tencate, I have experienced similar. I first drove my 2018 model 3 with FSD 12.6.3 last week-end, and as I reported above, it had a strong bias to the left and sometimes went over the line. I drove it yesterday and it was much improved but not perfect. I recalibrated the cameras, although my understanding is that we aren’t supposed to need to do that after a software update. I can’t tell that it helped, but it didn’t hurt.

Interestingly I just got FSD 12.6.3 on my 2017 model X and on my first test drive it didn’t have the lane centering issues. But it didn’t have the smoothness - still doing micro hesitations and some 90 degree turns were quite awful.

 

Since the most recent FSD update (moderator edit: M3LR Update 12.6.3), the set speed display has disappeared when on non-interstate roads. Anyone else experience this? It has been a long standing issue that the right scroll wheel does not work to adjust speed up or down on these roads, but the set speed display was visible. Now it's gone.

 

the set speed display has disappeared when on non-interstate roads. Anyone else experience this?

Yes...

On a limited access highway, the max speed is always displayed, even if below the max speed. On all other roads, the max speed is only displayed if you are going the max speed. You can briefly see the max speed setting by scrolling the right wheel up or down.

It has been a long standing issue that the right scroll wheel does not work to adjust speed up or down on these roads

Prior to HW3 FSD 12.6.*, that was true. Now with these latest versions, you can adjust the max speed up or down with the right scroll wheel on all roads. It may or may not respect your setting. Actually, I have been finding it to mostly respect my maximum, but not always.

 

FSD 12.6.3 Serious problem with lane centering and swerving.

Infotainment upgrade w/Intel CPU

Lane centering problem. Now Left justified
Feb 11, 2025 Greetings from St Louis,

MO, USA. My wife and I have two (his and hers) 2018 Model S. Recently both cars updated to FSD 12.6.3
I have initiated camera calibration multiple times on both cars. Makes no difference. We both observed the following problems:

1) Lane centering is gone. It is now left justified most of the time. Attached are pictures. Highway 270, 10:56a, light traffic, visualization display and windshield showing left justification. This picture is mild. There have been many times where the car was even more to the left side. Even crossed over into the left lane. The quantity of painted lines seems to have an effect. If there are double painted lines it puts the car over to the left even more. At night on two lane roads (one lane for each direction) with double yellow lines it pus the car body right at the 2nd line to the left. I had to disengage several times to avoid collision from car coming towards me in other lane. Sometimes a low minority of the time lane centering will be fine. Not sure why.

2) Phantom right turns. In light traffic on the highway occasionally for no reason the turn signal will come on and the car will start to change lanes then then switch back. A few times the car has swerved for no good reason.

3) When auto pilot is set to Full screen visualization the FSD Speed limit is no longer shown. When disabled it the FSD Speed limit (and now mode chill vs standard) is shown but randomly disappears. I think it is a very bad idea not to show FSD's allowed maximum speed limit.

The previous version of FSD did not do any of this. I'm wondering if this left justification just happening to legacy model S ?
Is it happening to model x or 3 cars as well ?

Yes, others including me have reported the same centering issue, above. I find it worse in my 2018 model 3 than my 2017 model X.

As far back as I remember, full screen visualization in legacy S/X has taken away key information in FSD. So I have not used full screen visualization for awhile.

 

We need mi/kWh and elapsed time benchmarks of at least 20 miles in:

• Chill + City
• Chill + Interstate
• Standard + City
• Standard + Interstate
• Hurry + City
• Hurry + Interstate

Try to include weather and traffic conditions along with anything else that might impact the results. The reason is for my future, 1,200 mi trips to witness the Starship launches.

It typically takes me 24 hours to drive 1,200 miles. I have to pay for charging, so CHEAP is good. But at age 75, FAST is appealing too. Full Self Driving handles GOOD.
