Tesla releases V14.3.1 focusing on smooth driving experience

Tesla launches FSD v14.3.1 update with a smoother driving experience. It’s part of the 2026.2.9.7 software update released for Model Y and other Tesla vehicles. The changelog is the same as before, but we have some of the user reactions that you should know.

Here’s what Sawyer Merritt said about his first experience with FSD v14.3.1.

With 14.3.1, you can now tap on the new “P” parking icon and bring up your different parking options. Mad Max mode on the highway feels slightly more conservative with top speed (favors low 80s more often). It will now get to the right lanes sooner to prepare for exiting the highway.

In his first drive, Mad Max did not go above 83mph, despite no cars around me most of the time. Follow distance is also more comfortable. Sawyer said he is having zero brake stabbing issues on 14.3.1, which was the case with his first drive with 14.3. On a further note, the Tesla enthusiast said that the Urban lane selection is improved. Navigation routes and occasional parking alignment still need some work, but that’s not a reason to hold back wide release.

Here’s what Zack (BLKMDL3) said after giving the FSD v14.3.1 ten drives.

“v14.3.1 feels like a big jump, even compared to FSD v14.3, even for “just” a point release build. Everything’s polished and smoother overall as expected.

Always after a big update or fundamental architecture changes, there will be a couple of rough edges. I was very impressed with how solid FSD v14.3 was, and .1 added a lot of polish to it.

The first big thing I noticed with this build was improved lane bias and preference changes. Notably, v14.3 would like to sit toward the left lane on emptier highways. In my driving tonight, I didn’t see any of that. Will drive a lot more tomorrow to verify.

In FSD v14.3, a new feature was introduced: a new P parking icon at your destination. At first, with v14.3, it didn’t show for me, then it did the majority of the time. With v14.3.1, it has shown every single time now. Something new in .1 is that you can now select it and change the arrival type from parking lot to garage, street parking, curbside, etc. Nice improvement and quick to change.

– As with v14.3, stop sign behavior is MUCH improved. It commits and doesn’t hesitate, no double stops I’ve seen, and a smoother acceleration and deceleration curve, leading to a more comfortable drive. Notably, speed bumps and dip handling are also buttery smooth, with a great acceleration/deceleration curve as well.

– Gated parking lots. One thing I noticed today with gated lots and garages is that it pulls up to the ticket dispenser way quicker and in a better position than before. It’s close and centered, exactly where I’d pull up. Goes right away when the gate opens, too, 10/10 no notes.

Parking- This is a big change with FSD v14.3+. It now picks parking spots more quickly and decisively. With v14.3.1, it’s even better; it’s picking the first spot it sees and commits, and sometimes they are even corner spots, which I personally love to avoid door dings. I saw a ton of corner spot parking today, which is awesome. When it’s parking, it’s so quick to decide which spot to take, but sometimes, once it starts pulling into the spot, it’s a bit slow to finish the maneuver, as well as a bit slow in parking lots sometimes. Now, the final 5 feet of the maneuver are the slowest, understandably. I saw an instance of the twitchy steering wheel as well.

Spot selection is so improved that it’s hard to even compare to v14.2.x. What a massive upgrade, and the decision-making is so fast and confident.

Speed control was great on my drives tonight, mostly city, but was behaving exactly how I would and expect it to now. Went perfectly with the flow of traffic on the profiles I selected. Hurry mode is dialed in, and doesn’t sit in the left lane, at least on the drives I did.

So cool to have Grok integrated with navigation. Tesla Self Driving and Grok took me to 5 separate destinations earlier with ZERO input. I just pressed start FSD, and it drove, parked, unparked, and got me to each destination without any intervention. Definitely worth watching the video I posted earlier of it.

Decision-making and reaction times are next level as well. It reacted to multiple bad human drivers we encountered tonight extremely well, and the reaction time is lightning fast. Will post some videos tomorrow of it reacting to other vehicles. Its reasoning is fantastic.”

Conclusion

Tesla is expanding FSD v14.3.1 for users across different models. Wait for your turn, as this update is released in batches.
