Tesla FSD 14.3 owner log: every update, dated.

We moved from 14.3.12 to 14.3.13. The random right-turn-lane signals that crept back into 14.3.12 appear fixed, Standard mode respects the speed limit far better, and Hurry mode has been good on the highway. Here is our October 31 update, followed by every earlier dated note.

· FSD (Supervised) 14.3.13, installed after 14.3.12. An early owner observation in one Model 3.

Read the focused FSD 14.3.13 review →

We are now on FSD (Supervised) 14.3.13. Toward the end of our time on 14.3.12, the car started to regress: it would turn on the right signal for a right-turn lane when there was no reason to move over. That surprised me, because I thought 14.3.12 had already settled that behavior.

So far, 14.3.13 appears to have fixed it. We have not seen those unnecessary right-turn-lane signals since the update, and the drive as a whole feels more stable.

Speed in Standard mode is noticeably better. It is doing a much better job of staying near the posted limit instead of running well past it, which was one of my longest-running concerns in the earlier notes below.

Hurry mode has been good on the highway. On our interstate drives it has felt confident and appropriate for the road.

I am hopeful this points to more stability from release to release. Because 14.3.12 seemed fixed before it regressed, I am treating this as a dated, early observation rather than a final verdict, and I will keep logging what we see. I still supervise every drive and step in when the road calls for it.

· Our Halloween owner update with FSD (Supervised) 14.3.12.

Read the focused FSD 14.3.12 review →

We are now on 14.3.12, and the car has gotten better about the right lane. I am happy to see that progress. What I still want is more consistent timing when we are approaching an exit.

On our recent drives, the move into the right lane can come later than I am comfortable with. I still intervene to move over earlier when a safe gap is available. I would like the car to leave enough room for a calm, predictable exit rather than making that decision feel rushed.

That is where my optimism and my expectations meet: the experience keeps getting better, and I keep hoping for every part of the drive to work more smoothly. I enjoy having FSD, and I continue to supervise and step in when the road calls for it.

This update concerns exit-lane timing. It does not establish whether the signaling, right-turn-lane or braking concerns in our earlier notes are resolved. Those observations keep their original dates below.

The car itself remains a good fit for us. Our reasons for choosing the Model 3 over the Model Y explain the household decision behind this review.

Right-lane timing looks better. The right signal has surprised us.

· FSD (Supervised) 14.3.9, late-September follow-up. Corrected October 31: this note was originally mislabeled 14.3.10; our car went from 14.3.9 directly to 14.3.12. This is an early observation in one Model 3, not a full release verdict or a claim that Tesla has identified a fault.

Read the focused FSD 14.3.9 review →

By late September, 14.3.9 seemed less eager to move into the far-right lane miles before an exit. That was welcome after our mid-September 14.3.9 drives, but it is too early to call the earlier behavior fixed.

On I-75, the car activated its right turn signal three times in late September without moving into the right lane. Another vehicle was in that lane on each occasion. The latest happened on the afternoon of September 27 while we were driving south, roughly two and a half to three miles from our exit. From the driver's seat, I could not see a reason to signal then.

I do not know why the system signaled or whether it was preparing a lane change it could not complete. The car stayed in its lane; this is not a report of a collision or an unintended lane departure. I am documenting the pattern because unexpected signaling can confuse nearby drivers, and I remain ready to intervene whenever FSD's behavior does not fit the road.

What remains untested here: whether the right-turn-lane resistance or braking jitters from our earlier 14.3.9 drives had resolved. Those older observations remain below, with their original dates. Use your own routes to evaluate FSD before deciding what it is worth to you.

Looking for our earlier 14.3.7 experience?

This URL began with our 14.3.7 review and now follows our experience through 14.3.12. The October 24 note covers our latest exit-lane timing experience. The September 28 note records late-September 14.3.9 observations (we went from 14.3.9 directly to 14.3.12), and the full review below describes 14.3.9. Read each observation with its date and version; a new note does not establish that every earlier concern is fixed.

In our September 8 first-100-days account, while 14.3.7 was the version we were testing, we reported frustration with some lane choices and hesitation at four-way stops. About 56% of our driving over those first 100 days used FSD (Supervised); that was an owner-reported share across the period, not 100 days of 14.3.7 testing or an intervention-free rate. We then had 14.3.8 only briefly before moving to 14.3.9. Our later observations are dated below so you can follow the progression without mistaking them for a 14.3.7 finding.

September 13, 2026 · First impression, with a September 23 follow-up below

14.3.9 makes me happier to have FSD than ever.

No more left-lane camping

Our biggest 14.3.8 frustration was the car parking itself in the passing lane. That stopped on 14.3.9, though later drives showed it now moves into the exit lane too early.

Quicker, more agile turns

The car commits to turns more naturally. It no longer feels like everyone behind us is waiting for it to make up its mind.

Stop signs still need patience

It completes the stop, then may wait a few seconds longer than a human driver would. That is safer than rolling through, but it can still feel awkward in traffic.

The short time on 14.3.8 was still enough to make the contrast obvious.

We did not have 14.3.8 long enough for a long-term test. We did have it long enough to notice repeated lane-choice and timing frustrations. Version 14.3.9 immediately felt calmer, faster to decide and much easier to live with.

This is a real-owner comparison from our routes and our car. The published 14.3.8 and 14.3.9 notes are nearly identical, so I am not claiming Tesla documented a specific left-lane or turning fix between them. I am describing the difference we actually felt.

The answer-first version

14.3.9 found a better rhythm, but its lane choices still need supervision.

For these September observations, our Model 3 was running overall software version 2026.27.6 with FSD (Supervised) 14.3.9. The upgrade was most noticeable in ordinary traffic, where lane choices and turn timing matter more than a flashy feature list.

01

Better lane discipline

It no longer settles into the left lane and stays there. But it can move into the far-right lane two to three miles before an exit and remain behind much slower traffic.

02

More natural turning

Many turns happen more quickly and confidently. At some right turns, though, the car resists the right-turn lane and appears to aim for the turn from a straight-through lane.

03

Still fully supervised

Right-turn lane selection, occasional unexpected braking jitters, stop-sign pauses, speed choices and pavement hazards all require an attentive driver ready to intervene.

September 23 follow-up · More time on 14.3.9

The left-lane fix may have gone too far.

The improvement is real: our car no longer parks itself in the left lane. But later drives revealed a different set of lane and braking problems that temper my first impression.

It moves right too early for an exit

Two to three miles before an exit, 14.3.9 can move into the far-right lane and stay there even when that lane is moving much more slowly. I like that it no longer camps in the passing lane, but this feels like an overcorrection rather than good lane judgment.

Some right-turn lanes are a more serious concern

We have also seen the car resist entering a dedicated right-turn lane, then appear to try making the right turn from the straight-through lane. That is not just an awkward choice. It is a situation where I would take over before the turn rather than wait to see what FSD does.

Braking has occasionally jittered

At times, the car has also jittered briefly while braking without an obvious reason to us. I do not know what triggered it, so I am not calling it a specific braking-system fault. It is another reason to keep supervising closely and be ready to take control.

This September 23 follow-up describes 14.3.9. Our September 28 follow-up on 14.3.9 concerns right-lane timing and unexpected signaling; it does not establish whether the older right-turn-lane or braking concerns are fixed.
What the release notes say

The release notes do not explain our entire 14.3.9 improvement.

That makes the boundary between documentation and owner experience especially important.

The published notes for 14.3.8 in software 2026.26.6.5 and 14.3.9 in software 2026.27.6 list the same major FSD changes. Those include upgraded reinforcement learning, a stronger vision encoder, broader traffic-sign understanding and a rewritten AI compiler and runtime described as reacting 20% faster.

The notes also list mitigations for unnecessary lane biasing and minor tailgating, along with improvements for parking, emergency vehicles, school buses, complex traffic lights, unusual objects, temporary system degradation and driver monitoring.

A release-note claim and an owner observation are not the same thing. We use the notes to explain what changed, then judge the experience by what the car actually does on our roads.
The remaining awkward moment

Stop signs are correct, but still slower than they need to feel.

Our Model 3 comes to a complete stop, which is exactly what it should do. The tough part is the pause that follows. It can sit for a few seconds after the way appears clear, and that feels long when another driver is waiting behind us.

Pressing the accelerator can prompt the car to continue, but that is a driver intervention, not permission to relax. I only do it after I have personally confirmed the right of way, visibility and traffic make proceeding safe and legal.

Complete stopThe car consistently gives us the full stop we expect.
A short waitThe pause after stopping can still feel overly cautious.
Driver confirmsNever press the accelerator unless you have independently confirmed it is safe and legal to proceed.

Accelerator input can make the vehicle move.

Stay attentive, check the entire intersection and be ready to brake. FSD (Supervised) does not make the vehicle autonomous.

Speed profiles

Standard is better, but I still want a tighter speed ceiling.

On our latest drive in Standard, a posted 35 mph zone saw the car start creeping toward 45. It stopped climbing at about 45, which is more comfortable than the behavior we had seen before, but it is still faster than I want from Standard.

My preference is simple: Standard should generally stay within about five miles per hour of the posted limit. Hurry and Mad Max can be the more aggressive choices for drivers who select them. Whatever profile is active, the driver remains responsible for the vehicle’s speed.

Driver responsibility is not optional.

If FSD selects an unsafe or inappropriate speed, the driver must correct it immediately. Full Self-Driving (Supervised) does not make the vehicle autonomous.

Summer Update highlights

Grok turned three errands into one excellent plan.

The FSD improvement is the headline, but software 2026.27.6 also carries forward the Summer Update features that made the rest of the car more useful and more fun.

The morning Grok got everything right

We asked Grok to organize lunch, a Costco run and a UPS drop-off. It built the entire agenda for us. I also told it I wanted a different route than the one the car would normally propose, and it set that up exactly the way I wanted.

Tesla’s Grok support page says Grok can issue navigation commands, make calls, search and play music, adjust temperature and control other supported vehicle functions. Tesla labels Grok as beta, so availability and behavior can vary.

Caraoke gets a little competitive

Caraoke, or Caraoke in Tesla language, now scores your singing while the vehicle is in Park. You can earn stars and track high scores. It is a small, cute addition, but the score makes it more fun if karaoke is your thing.

The practical theme of the Summer Update is personalization: Grok can help shape the trip, navigation can learn preferred routes and even a parked singalong now has a score to chase.
New active-safety feature

Automatic Collision Evasion can bring FSD into a manual drive.

The 2026.27.6 release notes describe Automatic Collision Evasion as a feature that can activate FSD (Supervised) to try to keep the vehicle safe and then continue driving. The notes say it can engage during manual driving if the system detects the driver is not sufficiently attentive, or if FSD may have been unintentionally disengaged.

We have not triggered it, and I hope we never need to. It should be understood as an additional safety layer, not a promise that the car will avoid every collision. Tesla’s Model 3 collision-avoidance guidance repeatedly says active-safety features have limitations and do not replace attentive driving or immediate driver action.

Do not test this feature.

Keep your eyes on the road and your hands ready. Automatic Collision Evasion and FSD (Supervised) do not make the vehicle autonomous or guarantee that a crash will be prevented.

Still on the wish list

Pothole avoidance remained on our 14.3.9 wish list.

The 14.3.9 notes list pothole avoidance under upcoming improvements. Until our car demonstrates it reliably, we will keep watching the pavement and taking over around hazards.

We would also like better speed discipline in Standard, more natural timing at stop signs, reliable right-turn-lane selection, smoother braking and smarter exit-lane timing. Version 14.3.9 is a large step, but it is not the end of the work.

So, would we recommend FSD?

Our September verdict: exciting progress with limits.

This assessment covers 14.3.9 through late September. The October 24 update on 14.3.12 adds our latest exit-lane observation.

The left-lane problem that frustrated us on 14.3.8 was gone on 14.3.9, and many turns felt quicker. Those are meaningful gains. But moving right miles before an exit, lingering behind slower traffic, resisting a dedicated right-turn lane and occasionally jittering while braking make this less settled than my first drive suggested.

I am still happy to have FSD and excited by the progress. I would not treat 14.3.9 as ready to handle every turn or lane choice without intervention. Stop-sign timing, Standard-mode speed and potholes remain on my watch list too. Our late-September 14.3.9 drives suggested better right-lane timing, but the unexplained signal events keep that update in the "still evaluating" column.

Our updated verdict: a dramatic improvement over our short time on 14.3.8, especially for left-lane behavior, with an apparent overcorrection toward the right lane and several situations where an attentive driver needs to step in.

FSD 14.3.12 and earlier owner-review questions.

What have you noticed on Tesla FSD 14.3.13?

As of October 31, 2026, 14.3.13 feels more stable in our Model 3. Late in our time on 14.3.12, the car began signaling for right-turn lanes when there was no reason to move over; 14.3.13 appears to have fixed that so far. Standard mode does a much better job of staying near the posted speed limit, and Hurry mode has been good on the highway. This is an early, dated owner observation, not a guarantee for every vehicle.

What have you noticed on Tesla FSD 14.3.12?

As of October 24, right-lane behavior is better in our Model 3, but moves into the exit lane can come later than I prefer. I still intervene for an earlier lane change when a safe gap is available. This observation does not establish whether the earlier signaling, right-turn-lane or braking concerns are resolved.

Is Tesla FSD 14.3.9 better than 14.3.8?

In our Model 3, the initial difference was dramatic: 14.3.9 stopped camping in the left lane and many turns felt quicker. Later drives exposed early moves into the exit lane, difficulty with some right-turn lanes and occasional braking jitters. This is our owner experience, not a guarantee for every vehicle or route.

What problems remain with Tesla FSD 14.3.9?

On our 14.3.9 drives, it sometimes entered the far-right lane two to three miles before an exit and stayed behind slower traffic. It also resisted a dedicated right-turn lane while appearing to turn from a straight-through lane, and occasionally jittered while braking. I would take over before an unsafe turn and remain ready to intervene at all times. We have not established whether 14.3.12 or later fixed those right-turn-lane or braking concerns.

What did you notice on FSD 14.3.9 in late September?

Right-lane timing seems better in our Model 3 so far. On I-75, however, the right signal activated three times without a lane change while another car occupied the right lane. The latest happened southbound on the afternoon of September 27, roughly two and a half to three miles before our exit. We do not know why it signaled, and this limited owner observation is not a full review or a universal defect claim.

How does Tesla FSD 14.3.9 handle stop signs?

Our car completes the stop but can still wait a few seconds longer than feels natural. The driver can press the accelerator to prompt it, but only after personally confirming the intersection is clear and proceeding is safe and legal.

Does Tesla FSD follow the speed limit?

The driver remains responsible for the vehicle’s speed. On our latest 14.3.9 drive, Standard began creeping from a posted 35 toward 45 mph and stopped climbing at about 45. That is better, but I would prefer Standard to remain within about five mph of the limit.

What is Tesla Automatic Collision Evasion?

The 2026.27.6 notes say it can activate FSD (Supervised) during manual driving when the system detects insufficient driver attention or an unintended FSD disengagement, in an attempt to keep the vehicle safe and continue driving. It does not replace attentive driving and is not a guarantee that a collision will be avoided.

Does Tesla FSD 14.3.9 avoid potholes?

Not reliably enough to treat it as a current capability. The 14.3.9 notes still list pothole avoidance under upcoming improvements, so drivers need to watch the pavement and intervene.

Is Tesla Full Self-Driving autonomous?

No. Tesla calls it Full Self-Driving (Supervised). The driver must remain attentive, monitor the road and be ready to take over at all times.

Can existing Tesla owners try FSD free?

Yes, if eligible. Tesla's FSD (Supervised) referral program, effective October 29, 2026, can give existing owners a one-month trial through a referral link redeemed in the Tesla app. Owners who had an FSD trial or paid FSD subscription in the past 12 months do not qualify.
