Tesla FSD 12.5.4.1 - First Impressions

[@seantiz]

On my first drive with this update, I was on the highway driving next to a concrete barrier/dividers. It suddenly and very abruptly pulled hard to the right and had I not had my hands on the yoke, I would have crashed into it at highway speeds. I could not see any reason for why it did this. I reported it. I was surprised, since it’s been several software iterations since I’ve experienced anything like this.

[@jmanjr]

That’s crazy and wild. My experiences have been mixed. They’re a long way before I can take a nap or send my kids off to school with this. A little concerned

[@LukeMilner206]

Highway hasn’t changed yet though… it’s Still V11!!

[@tsh4k]

@@LukeMilner206 Yup - sounds like a weird edge case with V11. V12 highway is rolling out now 12.5.6 (12.5.5 for Cybertruck only)

[@kottuning3294]

For me this version is unusable. I've had intervention after intervention and also some very unsafe strange events. I haven't had interventions like this since V10, its really terrible. I still think the initial V12 release has been the best for me

[@APatchworkCanvas]

If you haven’t already, look at all of your camera lenses and see if there is any dirt or a film over any of them.

I have a 2024 model Y long range with hardware 4 build. I use FSD for 90% of my driving. Here are some issues that I am experiencing with FSD 12.5.4.1: Phantom breaking approaching an intersection on a green light with no visible traffic hazards. Trying to make a U-turn on a street to narrow to complete the U-turn safely or successfully. Speed offset: consistently running 5 miles slower than the speed limit on service streets without any traffic issues. Lane centering issues when curving around to enter a freeway. Car seems to drift into the gutter and not stay centered. Failure to recognize well marked speed bumps. Does a better job at night. While driving on service streets car seems to stay in the right lane behind other cars driving at a slower speed, failing to move around them. Difficulty sometimes picking which lane to be in at approaching an intersection to make a left turn. Missing freeway offramp as the car stayed too long in other lanes to successfully merge into the right lane to exit the freeway. Caught midway in an intersection during a yellow light. Couldn’t decide what to do so it froze in the middle of the intersection. Didn’t know what to do at an intersection with flashing red lights. Has difficulty deciding what to do in heavy construction zones lots of traffic cones. Larry Baker

[@XBLWasabiSnooters]

Perfect play by play. I'm listening to your video while I work almost like a podcast. Didn't feel like I missed too much not seeing it. Great video

[@BlackTesla]

Nice!

[@mattocyt]

Live in NC and the truck speed limit signs in the mountains are the biggest failure point for me - especially when the signs are combined.

[@northshoreplaid]

My 12.5.4.1 had some real HARD BRAKING regression for no reason. One awful one is when entering a major highway with plenty of ingress lane and nobody in right travel lane. Turn signal is on...begins accelerating and suddenly and abruptly hard braking..then entering the lane!! Another one is a constant tap of brakes while traveling with no obstacles around..both rural and city driving. Last one is...stopped at an intersection. Already creeped up to limit and with cars coming from left or right, begins an acceleration, like darting into the intersection. I disengage because I feel like it's playing chicken with drivers. UGH!! 2 days is RoboTaxi announcement. Is this one of those give them a crappy release..then release the good stuff??? LOL

[@matejovich]

I have a 2018 MS and yes it is terrible!

[@TGWS007]

Thanks for suggesting to pull the cameras up. I will do that in the future in tight two way streets. For me you always show the best use of FSD, and I have suggested to my friends on Facebook to look at your videos to get a good feel for using FSD. As always very job.

[@BlackTesla]

Thank you

[@wydryfly]

One issue I’ve noticed in my 23 MS is that FSD gives little room for pedestrians walking on or near the shoulder on our local streets. We have narrow country roads and idiots walk their dogs literally in the road. To make things even worse, they commonly seem to be walking in the morning when everyone’s on their way to work and the sun’s in drivers’ eyes, and also around 5 - 6 PM in the evening when people are driving home from work. In FSD, my MS gave a couple of people only maybe 24 inches inches of space while passing. If I was driving, I would usually swerve almost into the other lane to give these idiots ample room. One lady was cursing me up and down as I drove past viewing her from my rearview mirror. I felt bad but the car wasn’t going to hit her, but it was much closer than I myself would drive.

[@rambo321]

10/10 event soon! thanks for the FSD video as always

[@Blucenturion344]

Great commentary as always; you're displaying a touch of humor which is appreciated. I just downloaded 4.1 while watching, gonna try it now in a M3P on W Coast. Yesterday path planner correctly said 1.9 mi to School Rd, but it wouldn't go into the traffic lane, and was headed for the large green sign (effectually splitting the difference) till I took over and stayed in exit lane. You wanta talk PTSD! Doing about 35 mph.

[@matthiasgrunwald895]

FSD is doing great process!

[@mulindejohn]

They are churning out these updates faster than you can make videos😂. I believe 12.5.6 came out yesterday.

[@BlackTesla]

Yes sadly the S is in service 😢

[@coolbart66]

Most of us still have HW3. On HW3, v12.5.4.1 has been jerky on turns and auto-speed has been under the speed limit. Otherwise, the ride is smoother, doesn't hug the yellow line anymore, and curb clearances on turns are better. BTW...I live near Montclair, NJ too and have the same conditions as you have.

[@RonnieDenburg]

I live near Montclair as well, but my experience has been way worse than 12.3.6; so bad that my wife won’t let me use it except on highways, minus on and off ramps. Can’t wait for a fixed version.

[@chadwickwood9843]

Way worse than 12.3.6 for me too. The pulsing throttle on

[@matejovich]

​@@chadwickwood9843agree 1,000% it's trash

[@anthonyr587]

It does NOT like tight right turns pulling off a main road. Twice it knew there was a turn there, and twice it overshot the small turn and went into the wrong lane and stopped dead. Luckily neither time there was a car. The second time as I was approaching the turn and watching, I had my hands on the wheel and break ready to take over because I knew it was going to struggle.

[@Charged-and-Driven]

Great video. This release is much better at avoiding curbs in my experience. Also recognizes the correct lane better. Still to fast over speed bumps and often does not see speed bumps at all.

[@flyshacker]

Nice drive. You’re a critical judge, but that’s necessary. Definitely the bus/truck speed limit signs need to be ignored, the car needs to slow down for speed bumps under all conditions, and then pot holes need to be avoided. All doable I think. Once the car has this stuff down it will have it forever. Go Tesla!

[@johnsteichen5239]

And school zoned !!

[@brianp8384]

Some states also have daytime and nighttime speed limits (usually 10mph difference) but FSD always uses the daytime limit.

[@philwelling7172]

Ha ha ha …love that video vignette “Common don’t hit that curb”

[@BlackTesla]

🤣

[@APatchworkCanvas]

I really like this version. Still have to pedal it and it has trouble with some turns but overall usable

[@alphadelta87]

14:18 - don't give away Tesla's secret!! 😅😅 Another great video, dude. Do you feel like the speed offset is more so corrected? Didn't notice any phantom braking, which unfortunately my 2018 M3P on 12.5.4 has been doing...

[@Blucenturion344]

My 2022 version of your car is doing the same thing.

[@alphadelta87]

@@Blucenturion344 funny I LITERALLY just got pushed 12.5.4.1 🙌🏻 Have seen reviews where the confidence is much improved and phantom braking is gone (again). Looking forward to testing it.

[@BlackTesla]

Yes its working as expected for us but doesn't seem to be for everyone. Luckily 12.5.6 that just dropped last night has a new speed offset feature to help dial in the offset you need.

[@JustPeaceLoveAndKindness]

Actually, I have a stretch of a big hill here in California with those different truck speed limits posted. It’s down right dangerous when FSD slams on the brakes to slow down to 35 mph in a 65-70 mph hwy.

[@DurfDiggler]

My 2017 Tesla Model S 75D just updated to 12.5.4.1 today (2024-10-21) was using 12.3.x yesterday. I’m hoping to see some improvements. It made some mistakes that it was making six months ago, like trying to use a painted-off lane (large chevrons filling the space between two lanes) to make a left-hand turn at a light. It was Accelerating way too hard ~100kW from 0-35 vs TA Autopilot would accelerate with less than ~50kW on the highway while traffic is up my rear. It was Braking way too late & hard when coming up to stopped cars at a traffic light or empty stop sign. It took a 90º turn WAY too fast from a 35 to highway on-ramp. It would stay at 45 MPH from the service road after entering the highway with a 65 MPH limit.

[@nicolebradley3959]

I'm installing this update on my tesla model 3 now

[@dialy1]

According to Tesla FSD tracker, v12.5.4.1 on HW3 has been performing incredibly well in Florida: 1187 miles and counting without any critical disengagement (75 entries). It mirrors my personal experience so far in the LA area on HW3. No disengagement. My only complaints are occasional phantom braking and weird stops and hesitation at green lights.

[@devo237]

Excellent commentary

[@MrArche123]

I have a 24 MX plaid. I drive the same route using FSD sometimes. ha ha. I am always afraid of the curb as well.

[@johnsteichen5239]

2 yrs on FSD for me. Have never clipped a curb. I no longer pay any attn to that

[@Tyson__B]

Which model? I wonder if the S/X are more prone due to the longer wheelbase.

[@janbottorff4642]

Using 12.5.4.1 on HW3 Model 3. Many times it has now given a "take over immediately" error at the same intersection. The problem is it can't cope with driving into the sun. This was verified today on a totally different road where I was driving into the sun about 30-60 minutes before sunset. My cameras are clean, this behavior started when 12.5.4 installed, and was not fixed by 12.5.4.1.

[@BlackTesla]

Not sure about this, It's already been proven that there are areas in the map that have corrupts data and when on FSD and coming to those spots FSD will crash causing it to throw that sign and then reboot the FSD App. You will know that because you will loose all surrounding visualization until it reboots as you see on my video.

[@zepplin839]

I think the model doesnt work as well on Legacy cars vs AI4.

[@jasonlop10]

I just tested it. It still shadow braked. Speed issue wasn’t resolved. It completely missed my exit and lastly it liked moving all the way to the left in the passing lane and go speed the limit

[@Johnbot201]

Curbs are also a PTSD thing for me. FSD 12.5.3 turned left into a curb and damaged the rear wheel in HW4 Model S. The alignment is a bit off now.

[@BlackTesla]

😔

[@U2B_Viewer]

It's end to end on the highway now. That's what we want to see 😊

[@craighermle7727]

Nice review! Have you had the "opportunity" to see how FSD deals with potholes?

[@BlackTesla]

Yes it doesn't deal with them just rolls over them

[@TeslaOutage]

I still have issues with it mising exits or taking it’s time to exit. Hopefully it will be fixed in the coming updates.

[@penadani88]

Hello, in a week I'm going to take a road trip from California to Texas, you recommend me to subscribe to the FSD.

[@philwelling7172]

Good man pointing out the speed bump

[@matthewowen1360]

Do you have to pay each month?

[@gameboy4696]

Mine doesn't do that at the beginning. It will move from a stop. The current issues I have is it sometimes stops at green or gets stuck in the middle of the road or in intersections. It still has phantom braking. the new version erased all the familiarity of the same routes in take on a daily basis. It does wide turns for no reason. I have 4 interventions so far where I almost hit a stop sign. My biggest worry is that it might hit a person as we have a lot of people with mental health issues and step in front of traffic all the time. It still doesn't scan efficiently and it still reacts like it's tunnel visioned.

[@OrganicStuff1]

12.5.6 just came out! Did you get it ? Heard it was for HW4 only sadly for my HW3

[@JetFire9]

Glad I sold my HW3 Tesla. It’s a dead end product, unfortunately.

[@dialy1]

Be patient. It’ll come to HW3. According to FSD tracker, at the moment, v12.5.4.1, in Florida, performs much better on HW3 than on HW4. Don’t ask me why but the data speak for themselves.

I got 12.5.4.1 a few minutes ago but haven't installed it yet. Does it improve the problem with regular phantom braking?

[@zachb1706]

I’ve heard about a lot of regressions and unpredictable behaviour on 12.5 . It’s strange, maybe the data they used isn’t as good as what they used for .3 and .4

[@BlackTesla]

I think Teslas biggest challenge is how a single build can be successful "everywhere". Some say 12.5 is bad other say it's the best version just depends on where you are imo.

[@zachb1706]

@@BlackTesla one of the examples I saw was FSD attempting to pull out in front of a car at a T intersection before the driver slammed on the brakes. They said they hadn’t seen that since v11.

[@diamond_h0us]

There was a larger parameter count model that I got and it was fantastic. The optimized versions that have been installed after that have been regressions on my MY with HW4. So much Phantom breaking it’s like going back to V11. 12.5.4 hard braked at a green light yesterday. There was no visibility issue.

[@zachb1706]

@@diamond_h0us that could be the answer. Did HW4 also get downgraded when they rolled out the “optimised” version to HW3?

@@diamond_h0us though really FSD should still outperform older versions even if it goes through knowledge distillation to lower parameter count.

[@davidsworld5837]

question 1 - how close to park cars will it got close to. 2 - it seems to give quiet a distance when stopping with cars in front. how far as cant tell does it stop from stop and give way markings can it see pot holes. its more can it deal with the unexpected the kerb missed it by an inch but it still did it. do you think it is improving is the improvements change points it did good to not so good

[@BlackTesla]

1 it gets very close 8-12niches 2 yes it gives extra room to stop then slowly moves closer to the back of vehicles. It is improving but there's still work to do.

[@creatorgenerator1998]

I'm not convinced HW3 (AI3) is up to the job. I get honked at when, even with the latest FSD s/w, it negotiates intersections far to slowly and misses opportunities. On the straightaways it's fine.

[@oscarreynaable]

Do you find that FSD is better in your 24 Model S than your previous S? If so anything in particular that stands out to you?

[@DS-nv8bi]

Have you had an animal or car dart in front of you during a drive? I am interested to see what automation does in a situation of surprise.

[@dialy1]

Many times. I have had the car brake and avoid hitting squirrels, flying plastic bags, palm tree branches, erratic humans, cars and trucks running stop signs… “Automation” can handle surprises.

Yes and it can handle it as well if not better than most humans but depending on the timing some animals may not make it

If you stay informed on social media and communities you'll get a sense of which version you will get. if you are not on social take a look at sites like Teslascope and notateslaapp to see which updates are going to which cars.

For me this version is unusable, super disappointed. No clue what is happening and why it feels like I'm back on V10. Heer's a funny one, yesterday I'm at a stop light waiting to go right. I'm the first vehicle waiting for the light to turn green. The wheel starts to do a jerking motion and I'm just thinking its just FSD being FSD. Next thing I know the yoke starts turning left, almost like a ghost was in the car with me. It turns itself two full rotations and only stops at full lock. So now im going right and my wheels are facing completely left. Had to disengage and reposition the yoke but things like this just haven't existed in forever

[@gwen4112]

Using HW3 for this version. Overall, a bit disappointed. Exhibits indecisiveness when making lane changes on highway, multiple curbs hits, and has failed to follow navigation at times. I tried rebooting in hopes of fixing the problem. I feel FSD regressed since the last version.
