🤦🏼‍♂️ What's Going On? - Tesla FSD 12.6.1

[@kmeyer5598]

As a HW3 person I really appreciate the review. Please keep them coming.

[@brianp8384]

Huge regression for me. Speeds are very erratic - mostly under the posted speed limit and then sometimes WAY over - extremely hesitant; sometimes it signals a lane change but then never takes it - just stays in the lane with the turn signal on; sometimes makes very sudden and unsignaled lane changes, other times it makes the lane change in two stages, first getting halfway into the lane, straddles the lane marking with left wheels in one lane and right wheels in the other; when a single lane splits into two or more lanes it will weave back and forth like a drunk driver trying to choose where it will go. I did a scroll wheel reset and then even reset the DAS computer but I've gone from using FSD 95% of the time to zero and waiting for an update that will hopefully fix this.

[@MrAndreybond]

I have the same issue, it feels worse than the very first version 🤦🏻

[@weich1q2w]

We got it on our model Y and it's basically solved driving in our area in the midwest. It's smooth as butter and the speed control is good. I just wish the speed profiles worked on roads slower than 50mph. It's surprising how much it differs by either per car or based off the location you are in. I'm not sure why some people are having not that good of a time. For us it did our routes perfectly (10%, 5mph off sets) in town and on the interstate. I didn't even have to touch the wheel or the accelerator like I had to constantly do on 12.3.6 and more so 12.5.4.2. The in camera for me is also less sensitive. 12.5.4.2 would cry if I looked away from straight on for more than a few seconds. During our drive around the lake yesterday (windy roads) I didn't even have to look forward it let me look off to my left and it didn't really even care. Only when I looked down or at the screen did it get upset. Seems to be less upset when I look at the screen with this update as well, and doesn't seem to snowball the aggression at me like 12.5.4.2 did constantly The only regression if you want to call it that is it seems to be a bit more strict about how clear the cameras are. I just had a tiny bit of condensation on the inside of the glass on the pillar and it wouldn't re-engage it. So I stopped the car, got out and then restarted driving and eventually it let me back in but it kept complaining about it - still drove great

[@kenhiett5266]

The people getting views on sharing FSD faults are to the point of having just enough at the bottom of the barrel to work with. I know because I have about 40 hours with 12.6.1 in my '23 Y. The vast majority of my drives are maybe one or two minor corrections.

[@The_S1ngul4r1ty]

So the vast majority of your drives require at least one intervention. Got it. 👍🏻

[@TarequlSifat]

2021 MY here. I can attest that 12.6.1 is a huge improvement over 12.5.4.2. If you think otherwise then you must not have used too much of the 12.5.4 branch or the problems may be specific to your location or car.

[@waynekurt162]

I bought FSD in May 2021. On the highway it’s a useful tool. I always pushed the minimize lane change, when I want to relax. Now that that seems to have gone away, I’’ll be in full test pilot mode all the time. On side streets, I’m skeptical, it will be anything more than a toy for a long time to come. Enjoy your content.

[@mihaiconstantin-pau5116]

I got a huge improvement with this version. Speed control choice is not great (fixed % means I am too slow in slow areas or too fast in fast ones), but other than that it has been great. Super smooth, decisive when needed, patient when needed

[@AJRaerial]

Profiles don't have any effect on the city driving less than 50. Speed control is separate for those roads.

[@iowatesla]

Good to know.

[@bushwookieadventures]

2:45 by law if u are already in the middle of the intersection as the light is yellow you are not breaking any laws, ur tesla made that turn legally

[@TuneupMagic]

@bushwookieadventures When a traffic light turns yellow, you're required to completely clear the intersection before the light turns red. In this case, @iowatesla's tesla failed to clear the intersection after the light turned red -- so, FSD v12.6.1 did an illegal left turn.

[@gameboy4696]

Unless you're driving a bus or a heavier vehicle, entering an intersection on yellow even if the turn was completed on red is allowed. So yes Tesla did a bad move and you should have stopped instead of entering the intersection.

[@TuneupMagic]

[@jc_usa_21502]

I have horrible highway experience , had to use enhanced for 2 hours highway drives.. tried all profiles and speed settings combination, that highway is HORRIBLE , slows down in turns , speeds up like maniac, passes people, brakes after passing people, speeds up when people pass it .. and in town, so slow... like 5mph in residential and then speeds up to 40 when you tap accelerator.. worst since last year for me

[@brianp8384]

Same for me. I've been using FSD for over 3 years and this is by far the worst update I've experience.

[@PumpUptheJam81]

Huge improvement for me regarding smoothness, turns and lane change. My issue (so far in San Diego) is improper lane selection (not getting in the left turn lane and staying in a right turn lane after highway exit etc).

[@RogerWilsonTodd]

Same config as yours. I’m still disappointed with lane decision-making/timing.

[@StormyDog]

I've had 12.6.1 for a couple weeks. For me it's far better than 12.5.4 which wasn't bad. It's especially better on the highway and the steering wheel stutters are gone, it's very smooth. I use chill mode and keep the speed offset low, then it's easy to adjust to the desired speed with the scrollwheel. Much of the problem with speeds is a signage issue. Slowing down for small towns works fine. Coming out of towns is the issue because around here instead of posting a speed limit sign there's a sign that says "end speed limit". What does that mean anyway, that I can go 100? That said Tesla needs to do something about their map vendor. Sounds like they may be in the process of trying to build their own maps from their driving data but that's just a rumor at this point. I am looking forward to 12.6.2 which is rolling out. Always happy for progress.

[@BitJam]

Thanks man! Too bad about the FSD but at least we are getting the weather overlay. It may be the same with FSD, we will get it eventually but it will take time. Worse comes to worse, I think we will be able to buy a hardware retrofit.

[@billnipp2309]

V13 still has issues that they say was fixed. Like slow lane changes and having to tap the accelerator to go more than the speed limit. So, still not there yet... ty

[@disneymike3311]

Thanks for the video. For me, 12.6.1 is a minimal improvement for these reasons: Speed profiles not staying at your set speed limit, car not staying in centered in the lane, running red lights. It’s confusing to me why FSD seems to have some issues, like lane centering, perfected, the a new update comes out and it now can’t stay centered???

[@tibbersup4911]

Thank you for sharing and Thank you for being Honest. i have had 12.6.1 for about ~1week now (2021 long range model Y) and i don't like it. I'm missing 12.5.4.x now.

[@khuo0219]

I am also getting a lot of hesitation at stop signs. The all-way stops are very bad; it would inch forward and then stop, giving confusing signals to other drivers at the intersection.

[@edwcory]

2020 Model Y and just had my failed FSD computer replaced, on 12.6.1. I like most of 12.6.1, but I don’t like on the highways that I can no longer cancel lane changes. If i cancel a lane change, the car continues to change lanes.

[@jandemckay]

Thanks for this. I have H3 but haven’t purchased FSD yet. Do you know if any improvements to FSD trickle down to Autopilot or are they completely discrete software offerings?

[@APatchworkCanvas]

Auto pilot updates have basically been abandoned while they work on fsd.

[@ekaa.3189]

Yep, saw lots of issues with speed control. It likes to slow down on local, rural highways, and interstates. Yeah, it wants you to take over going into parking lots. Also did that to me turning onto the short stub road to the Dows, IA Supercharger. Less hesitation at intersections with wide stop lines, but it's still there.

[@r.schmalzried7315]

I like the FSD improvements as it is smoother. Still not perfect, but I use it on almost every drive. I still have an issue with maps that still haven’t added a major highway that opened in Raleigh back in September.

[@larryellison1788]

Thanks for the quick video. We are still on v12.5.4.2 in our 2020 M3LR. Your observations with this version sounds like no difference or actually a regression from what we are currently using. I have updates turned off and will wait for more reviews and possibly a future release. My biggest complaint is speed and hesitation issues and I am not a fan of the new driver profiles.

[@markcarlson3501]

I only had 12.6.1 for one day before I canceled the FSD subscription in my 2021 MYLR. From what I could tell, the new version didn't provide any improvements over the previous version, and maybe a little worse. However, the reason I canceled was because when the sun shines in the pillar cameras, FSD won't work due to glare or condensation on the inside of the glass. Aside from that, FSD seems clueless on lanes when the streets are snow-covered. I had service replace one of the cameras and clean the inside of the glass a few years ago, but it didn't resolve the issue. I heard new versions have heaters to prevent the condensation? But I'm not sure if glare is still an issue with the newer HW4 cameras.

[@dougfrith5001]

It’s frustrating when the two steps forward also come with one step back.

[@ekaa.3189]

To me this release was one step forward, and two steps back.

[@iowatesla]

Agreed.

[@brianp8384]

For me it's one step forward and twelve steps back. with 12.5.4.2 I had many intervention-free drives. With 12.6.1 I intervene at least once per mile.

[@alexanderdiaz9175]

When is 12.6.1 coming to the Model 3?

[@StormyDog]

Never, you're getting 12.6.2 which is starting to roll out.

[@randyvillarroel807]

Still much better than 12.5.4 imo. Highway has been great so far and I like to be able to control max speed. But I’m still finding errors here and there. Still not 100%.

[@jc_usa_21502]

my highway is worse than ever - slows down at turns and erratic behavior ..

[@johnlabernik4599]

Maybe try cleaning your windshield

[@highskyproductions764]

I would recommend getting your front camera cleaned, it fixed the red steering wheel warning for me.

[@iowatesla]

Did you clean it yourself?

[@highskyproductions764]

I ended up having Tesla do it because I was already taking the car in anyways. You can definitely do it yourself though look up a video. It’s quite simple

[@benso87]

Well, I'm slightly less impatient for this on my HW3 model 3 now.

[@MrAndreybond]

I Have MY with V3 intel.. this was a HUGE downgrade for me, the FSD became unusable. Always slows down to 30 on 35 roads, very hesitant and unconfident. Could change its “mind” half way through the turn and create dangerous situation.. I use to mainly drive on FSD, now I can’t even use it. Why is it so different for people??

[@ekaa.3189]

I dialed the over speed limit to 15% and think I should set it even lower. One can use the scroll wheel to modify faster or slower for a stretch of road. I kept finding I needed to lower the limit at county changes. I even had problems with it wanting to keep at rural highway speed as it entered small towns. It was totally ignoring the speed limit drops. Not even registering the signs. Exiting towns it was often very late in accelerating.

[@dennisschlieckau8723]

Ignoring speed zones coming into small towns is a major issue with Auto speed period. I had to turn it off. This has been the case from the beginning of the Auto speed feature rollout last spring. The problem with small towns is also lack of other vehicles on the road. If don’t have a lead vehicle to make the car slow down it won’t. It seems like the neural net training is heavily biased to large towns and Metro where people tend to drive well over the posted limits all the time.

[@jimadams2113]

Elon has said HW3 cars will be updated to HW4 if they are not fully capable of FSD. I am a bit skeptical.

[@iowatesla]

I am too.

[@Neubs-xv8tw]

Agreed, I highly doubt that'll actually happen for a number of reasons.

[@StormyDog]

Correct, but limited to those who purchased full FSD. Most likely a paid upgrade for the rest of us.

Interesting experience. I just got 12.6.1 coming from 12.5.4 and find it is a massive improvement. No hesitation and brilliant lane change decisions. So smooth.

[@iowatesla]

I'm hearing very different experiences from people on this version.

Same. Massive improvement on 2021 Model Y 12.6.1 compared to 12.5.4.2. Not sure why people are having different experiences.

I see this video is with Intel processor. I have AMD so maybe that is making a difference?

[@humaliens8759]

@@umneycreep I got it on my 2020 model Y and it had pretty much made FSD unusable. I have to intervene with the accelerator about once every five seconds. It will not accelerate from stops. Phantom breaking. Confusion at turns. The previous version was way better wish I never would've updated. I'm wondering if it has to do with an older chip set.

[@screamingiraffe]

HW 3 is what and HW4 is what? Update: seems HW3 is Intel based (2019-2022) and HW4 is AMD based (2023+)

[@CBAclubpenguin]

this upgrade is not an improvement. I get too much hesitation, under speed performance and too many lane changes. They also took away the choice to reduce lane changes (bummer). Merging on and off the highway is much better though.😥😥

[@rescuetechmn]

As good as it has become, it’s truly sad that ElonMusk [ratBastard] and all Tesla cronies [employees] have dropped the ball on all of their customers who own HW3 and below Teslas! Planned obsolescence can not be acceptable on a Tesla like Apple forced on their customers!

[@authorizeduser680]

A terrible step backwards with the new driving profiles. I hate it to the extent I just cancelled my monthly FSD. They eliminated the ability to minimize lane changes, eliminated the optional warnings upon lane change and for highway driving you can no longer effectively dial in the speed you want. You can but the profiles decide for you now. It needlessly changes lanes and you cannot stop this. I've reverted back to AutoPilot which is much better for highway traffic. I was really disappointed in the new approach that seems to mold profiles into one size fits all. Also it nags more than ever. Yes the speed control has gone backwards too. Hesitation is still a problem.

[@gameboy4696]

[@dweeder1453]

very accurate!! Same as my experience. Have to intervene many times especially in areas where roads are new or there is construction or there are interesections and turns. In snow it disengages at ever stop light if there is snow on the road.

[@jkimo11]

A little off-topic here, but I wondered if you could comment on my current situation with my new model Y. I've done some research and I'm losing 15-20% of battery capacity over night due to the cold. ….. around zero. Apparently, This is normal, but it is a daily loss of about 59-60 miles of range. (20% of 337 miles). That does not seem very efficient. Apparently, most of this is to keep the battery warm. My question is what kind of power consumption will I see if the Tesla wall connector is hooked up to a fully charged battery over night ? How many kw (Apprx.) are used to keep the battery warm. It is not garaged and this situation is with it not hooked to a wall connector. I hope to have that hooked up next week I’m currently super charging.

[@65ramblerman]

On 1/19/2025 I charged My Cybertruck up to 80% then charged my wife's ID4 up for 4 hours. I then plugged my truck back in for 11hr 43min, I used 5.6 kWh during that time. It went down to -6°F with 20MPH winds that night and parked outside. That battery % gauge shows battery available, as the battery warms up you gains some of that back. If you set the precondition interior and battery on a schedule you will have re-gen on deceleration a lot sooner, unless it is really cold out.
