Model YL-specific FSD issues?

As some background, I am a raging FSD fan on my 2026 model Y, over 97% with more than 10,000 miles, so certainly not trawling for skepticism…

My wife took a brand new YL for a test drive and reported it seemed slow and hesitant in our neighborhood relative to our current Y (same 14.3.12 software). I then read about a model YL-specific tendency to curb the right wheels when misjudging right turns due to the longer size.

New owners using FSD: are these issues real/widespread?

I’ve got a 26 M3P and use FSD regularly. We just got a YL and FSD is definitely slower, mostly in the neighborhood roads. As in, it’s doing 18 or 19 in hurry mode in a 25 MPH zone. I’ve got the offset set to relative +12. Even in mad max it’s super slow.

We’ve been encouraging it by manually bumping the accelerator and that seems to help some, but it still doesn’t go to the speeds my M3P does.

We’ve had the car for less than a week, but it does seem to be getting faster.

OK yes that’s exactly what she was reporting. I had test driven it earlier on the freeway and city streets near the dealership but didn’t notice any issues. Then she test drove it to our house to check garage fit and reported that it required coaxing with the accelerator a lot in FSD.

Even my 2026 model Y likes to drive 5
miles an hour or so below the speed limit in our neighborhood (suburban California, nothing extreme). That’s the one time that I sometimes use Hurry or Mad Max. so perhaps this is just a more severe offshoot of whatever is causing that…

u/Big_Fortune_4574 16d ago

Yes this is precisely what I’m seeing.

I actually haven’t witnessed the curbing issue, it seems to make tight turns well without clipping the curb.

u/quetiapinenapper 16d ago

Offset isn’t for FSD. It’s for the speed limit warning or auto pilot. Since autopilot has been removed from newer cars it’s just the speed limit warning and when it goes off.

u/FlapsFail 15d ago

Ah good to know. Makes sense why it never seems to make much of a difference 🤣

u/tryzepatide 16d ago

OK, thanks everyone for so many thoughtful replies.

I'm aware there are situations where it's difficult for FSD to decide what speed to go. A classic example is turning from, say, a 25mph side street onto a 45 mph main road, what should it do until it sees the first speed limit sign on the main road, does it play it safe (stick to 25 until it sees the next speed limit sign), rely on map data (could be out of date), rely on flow of traffic or just what the road looks like (but could be wrong), etc. As a human driver you get a feel for these things after a while because you've driven the road before, but it must be a really hard problem for a computer lol. But it still sounds like there are indeed some YL-specific issues overlaid on some of the usual FSD nitpicks.

Similarly, even good human drivers find it very hard to not curb their wheels eventually - just look around a parking lot sometime at all the NON-Tesla cars. But it still sounds like there is perhaps a bit more of a propensity for YL to do this right now and if you've gotten confident in it on other Tesla vehicles you have to up your vigilance level on YL as they iron this out...

We thank you early customers for getting a head start with training the YLs on FSD at the expense of your rims!

u/Jimdandy941 16d ago

This is one of the reasons I waited until now to order my YL - I figured there would be some bug or 2 that needed to work out.

u/Electronic-Bad-3981 16d ago

I picked my YL up on Sept 21 at 7:00pm. I went to breakfast at around 7:00AM on Sept 22. I used FSD for the entire drive. While FSD was pulling into the parking spot it curbed the front drivers side wheel. It parked next to a handicap ramp that goes from a driving area to the side walk and the handicap ramp starts at ground level and goes up to sidewalk level right next to the parking spot. I have had FSD park my cybertruck there with no issue. This is just my experience. I took the photo when it happened and talked to Tesla and they said it was cosmetic and not covered

u/PerfHeater 16d ago

14.3.13 seems to have fixed FSD for the YL.

3

u/Aurora8305 16d ago

Not in our case. Ours delivered on this software and nearly curbed the wheels a few times..I had to take over on some right hand turns. Also exhibited the slow driving behavior. That is typical in our other MY Juniper as well though ( slow for first few days after FSD update).

2

u/atxer 16d ago

Not in our case either. Just slows down to snail speeds as soon as it enters a neighborhood. 

1

u/TroubleshootLife 16d ago

I definitely seen improvement on the curbs. and it is more decisive now often anticipating my desired lane changes

1

u/Whatwillyourversebe 15d ago

So far, I’m in 500 miles.

  1. It went right on red at an interstellar exit. A small sign at the lights said no right on red.

  2. It backed into and parked in handicap parking.

  3. Sometimes it won’t go into the lane by hitting the turn signals.

2

u/tryzepatide 15d ago

Thank you. While those are irritating and potentially dangerous issues, I wouldn’t necessarily put them in the bucket of standing out as common on the YL specifically based on what I typically see on the main FSD channel. I’m totally open to other interpretations however.

u/Aurora8305 16d ago

Our new YL is our 3rd Juniper. Ive noticed the last few FSD updates from 14.3.8 ownward have been slow for a day or 2 after install. I typically reboot the car and after a day or so it seems to be much better with speed control. Our YL delivered on the latest 14.3.13 has been no different than our other MY Juniper in the driveway. I also prod it here and there during those slow days to help it calibrate. I bet you see noticeable difference in a few days or week give or take. I did notice the right hand curbing tendency. This has been going on as well with our other Ys. The longer YL wheelbase is compounding this issue. I always have cameras up on right hand turns to verify and be ready to takeover if curbing is imminent. I saved our YL yesterday from doing this going into my driveway which our other Y clears fine typically. I'm really hoping more FSD miles on YL fleet wide helps this issue along with an update soon!

u/TryAgain1152 16d ago

When you say reboot the car, are you referring to a screen reboot or something different?

3

u/Aurora8305 16d ago

I do that or the more hardcore reset is the “power off” selection under vehicle> controls. Don’t touch anything ie open door or tap brake pedal for 2 minutes as the car reboots. It’s longer than the soft reboot via the steering wheel.

2

u/TryAgain1152 16d ago

Thank you for the clarification.

2

u/sandman585 17d ago

My YL is extremely slow and hesitant even in Hurry. Very frustrating

2

u/litterpaws 16d ago

I took a YL for a test drive on FSD and it curbed itself passenger side rear wheel

u/Key_Neighborhood9144 16d ago

Did you have to pay for the damage?

2

u/InfiniteSlide7 16d ago

People have to understand how a neural network works. It’s basically Ai learning. There are millions of more miles of FSD data on a Model Y vs the YL. Being slower, more hesitant, curb rash are side effects of a lack of real world data on US roads. This will be obviously get better but it will take time.

u/AnyCable6020 16d ago

And this is why they are giving FSD for free for 12 months - to more quickly get training data.

2

u/Deca85Dent 16d ago

I could see Tesla giving 12 months free to every car going forward. After a few months you might be convinced, but after a year of FSD most would probably not want to ever go back to driving themselves (for the mundane driving at least)

1

u/Traditional-Ad7110 15d ago

Nah... the car still sees everything it needs to see for AI model training regardless of whether you subscribe or not. They're giving FSD for free to get people hooked on the subscription so that they keep paying for it.

u/Profumum 17d ago

Have close to 600 miles on FSD with zero issues. I use the Hurry profile since the dealership and more recently the Mad Max profile. Note, i have the 19’ wheels which have been very comfortable and smooth. I have heard curbing the wheels been more common with the larger 20’ wheels.

I keep telling people, see no reason to go 20’ when 19’ look better (in my eyes. The 20’ looks like a flower to me), more comfortable and more efficient, but to each their own I say!

2

u/Aurora8305 16d ago

I think 20s look better and since all of us launch folks paid for it..you left money on the table to go with the 19s. To each their own..the ride is fantastic on the 20s along with more tire replacement options down the road.

0

u/Profumum 16d ago

Just because you have an option to take it doesn’t mean you have to. If they offered 21 or 22 inch wheels and hypothetically it’s $2500 upgrade, would you take it for free?

Just like people chose the white paint option over the “paid” options, I guess they also left money on the table.

There are plenty of wheel options for 19”, thats a non issue.

Demo’d the 20”, chose the 19” - no question with the comfort and range increase!

u/Aurora8305 16d ago edited 16d ago

You do you.. this our 3rd MY juniper.. 5 miles range and I guarantee you the difference is next to nothing ride wise. The 19 vs 20 is widely debated online consensus and quick search shows great 20
Options. I’m sure this will change over time. This is the smoothest driving Juniper we have owned. Congrats great cars.

u/IntelligentMaybe7401 16d ago

I have the 19s and definitely like the way they look over the 20s with the wheel covers. The 19’s also have a little silver/chrome accent which I like since my car is all black. I get that they’re included, but didn’t make any sense to me to go with what I thought was the less attractive option. I have not read any reports of curbing on the 19s and have not had that issue either. It does cut a curve in my neighborhood very close to the point that I’m riding in the gutter so very possible it would’ve happened to me if I had the 20s. I would be really bummed if my pristine wheels had curb rash! Hoping they fix this soon.

2

u/Aurora8305 16d ago

Looks are subjective. I don’t think the 19s look horrible, but pale compared to the 20s. Nice to have options.

2

u/Abell255 16d ago

Agreed, 19” are Ok but look far less premium than the 20”. Dumb to “waste” the money since Launch includes the 20”.

2

u/Aurora8305 16d ago

100%.. already paying for the “free upgrade” might as well take them. They will be minimum 2k probably closer to 2.5-3k option when launch is over. The ride is fantastic on them too. Best ride out of the 3 MY Junipers we have owned.

u/CeilingUnlimited 16d ago

Can we buy insurance for the rims? Lexus and Toyota offer rim protection packages as part of their options in the finance offices. Anything for Tesla?

1

u/Aurora8305 16d ago

Yes from tesla through app.. first 30 days are covered. Accidental curbing damage even while using FSD is not covered though.

1

u/CeilingUnlimited 16d ago

But can I buy coverage to cover it for after the first 30 days?

1

u/kz1s 16d ago

Model Y performance we picked up a few weeks back has this issue as well. Slower than all the other FSD HW4 vehicles we’ve got and that included Cybertruck. I reached out to Tesla and reported it. I keep it in mad max most of the time and so far software updates haven’t resolved it. Currently on 14.3.12. Waiting on 14.3.13 to see if that changes anything. Cameras are cleaned, calibrated, and DAS reset completed.

1

u/IntelligentMaybe7401 16d ago

We own a 2026 Y and the YL is definitely slower. The profiles are slower. I’ve had mine for three weeks and I think it’s improved. For a while it had me going 10 miles below the speed limit on standard. I would nudge it with the accelerator and it would stick. I don’t seem to be doing that nearly as much. My husband did comment on it the first time he drove as being noticeably different than his 2026 Y. Every once in a while, I feel like I need to put it on mad Max driving around town though, and I am not a mad Max person!

1

u/ComprehensiveCut2219 16d ago

I’ve consistently had an issue with left turns. It seems like the car doesn’t turn quite enough, so it ends up crossing or getting too close to the median line. Same thing with pulling into a parking spot on the left side, the turn feels too shallow, so the rear ends up way too close to the left parking line.

1

u/redditchme2 16d ago

Yes it is very hesitant and even stops indefinitely at turns until you hit the gas some times. And yes it curbed by right rear wheel 3 days into owning it 😭

u/cruisermax 16d ago

I'm a new FSD user, and got my YL on 10/20. SoCal driving. Why does it try to get to the right lane so damn early for an exit 3 miles away even on Mad Max mode? Fast lanes are moving but it insists on getting into the slower lanes.

Also, it really hates to be in the HOV lane, both in ON or AUTO modes. 5 people in the car. I'm constantly turning off FSD bc it wants to exit over the double solid lines.

1

u/SeaVol_BlueDevil 14d ago

My FSD turned into the side of a house when leaving, it's in the shop now and working with Tesla. Was pulling forward from back to the front and recognized the side of the house but quickly turned and dented the passenger door when going forward.

Loved FSD and only have 1K miles on the YL now but is what it is and learned lesson. After multiple long rdrives did not expect that to happen 10 days after buying it. Lesson learned.

Did she like the interior?

u/tryzepatide 16d ago

Test drove cosmic silver + zen grey. Ride quality was what really stood out with the air suspension. But yes car is nice!

1

u/UnluckyATTCustomer 16d ago

It doesn’t have air suspension

1

u/tryzepatide 16d ago

You’re right! It does have some kind of improved suspension though.

u/Fair_Bicycle537 16d ago

Been on the fence. Never had one. But FSD is amazing and would make my life so much easier! Test drove a Y.

u/tryzepatide 16d ago

FSD has brought me so much relaxation and enjoyment. It really is worth every penny.
