Any info about software versions 2021.43.xxx appearing on new vehicles?

My MYLR with HW 3.0 and AMD Ryzen was built Jan 27, 2022. It was delivered Feb 5 with software version 2021.43.101.2 and today just got an OTA to 2021.43.102 instead of what I was expecting which was some version of 2022.4.5.x. I am trying to find any info on why a recently built vehicle would have software versions 2021.43.xxx which corresponds to calendar week Oct 25, 2021 to Oct 31, 2021, which seems pretty old. Tried looking on the autopilot review's latest tesla autopilot software updates but no info about 2021.43.x there. The TeslaFi tracking site shows a 27 vehicles have done the same upgrade, all today with mix of Model Ys and 3s, of all types.

Anyone have information about what 2021.43.102 is about, why is it apparently so old, and why Tesla just started pushing out today, why was the car not upgraded straight to the latest software version (2022.4.5.x)?

Something to do with my hardware components? Something to do with recalls?

Your car is new. New cars always start with a stable factory version. Typically new cars won’t get updates for 2-8 weeks.
Understood and expected. But my question was not why was it delivered with an old version of the software (2021.43.101.2), but why was it just upgraded to 2021.43.102, which is just as old. If Tesla is going to push out an OTA update, then why not push out the latest version.

Because they are giving you a minor update, but keeping you on a factory stable version rather than the latest update. This helps you adjust to the new car without features changing right away.

Thanks for posing the question, I’m in the same boat. Picked up my MYLR on Feb 5th. That day was asked to upgrade to 2021.43.101.2 and tonight got the message to upgrade to 2021.43.102.

With all the supply chain issues I wouldn't be surprised if there were minor changes in your config that needed firmware updates and it is easier/safer to do this on an stable older branch. Eventually it will get merged to the main line and you will start getting those updates.

Where are you getting this misinfo? Just making them up? I’m on my 3rd Tesla, never waited 2-8weeks for update.
No need to have an attitude. No, it is not misinfo that I made up. Generally this is how it works for most people and you can find this same info all over this forum. You can also get the same info from your service center.

Note: This discussion was originally part of Post #1 of Thread Trying to Make Sense of Recent Software Versions.... Apparently, the information table there became so large that extra language had to be jetisoned.

Discussion: What If Your Car is “Frozen” at a Particular Software Version?

Tesla owners have come to enjoy fairly frequent software (firmware) updates that can revitalize and improve vehicle operations. Customers now anticipate and look forward to major software roll-outs that bring exciting and innovative new features. A downside is that software update delays can create understandable anxiety and frustration. But not all complaints are fully justified. Based on TMC posts, there are a number of more-or-less legitimate reasons why a car has not received a particular software update.
  • New cars may not at first receive software updates, sometimes for months.
  • Tesla software roll-outs may be slow-paced and/or target subsets of cars rather than the whole population.
  • Releases can seemingly drag out for days and even weeks. This can be normal.
  • Updates may not apply to specific model-years, regions/countries, MCUs, and vehicles with particular hardware.
  • For various known and unknown reasons, not all cars get all updates and at the same time.
  • Updates may sometimes be hindered by other factors (e.g., inadequate WiFi connectivity).
Some tips, observations, and suggestions:
  1. If you are in the USA, read Tesla’s description about its software updates here: Tesla Software Updates (USA). (For other countries, check your Tesla website for support on this issue.)

  2. Be aware that if your car is new, it probably received special factory-installed firmware (e.g., 2021.35.102.2) that (a) is apparently intended to stay with the car for an unspecified initial “breaking in” period (my words, not an official description) and (b) takes time (e.g., 1 to 2 months) to be replaced by regular software updates (“Production Builds”).

    As I say in Post #3, below, my guess is that the reason for this is so that the car can be "tested" for a couple of months to iron out any bugs, electronic or otherwise, before it starts receiving normal software updates. That way, if the owner finds any problems they will not be due to new software.

  3. Tesla releases updates in sporadic batches or waves, often slowly, seemingly car-by-car, over time. This is probably so that if serious unforeseen problems materialize any resulting impacts can be contained within smaller groups of cars (rather than world-wide) and the range of impacts minimized. (See TMC Forum Reference; Post #14.)

  4. Sometimes otherwise seemingly eligible cars may skip updates for one reason or another. (See TMC Forum Reference; Post #9.) The bottom line: a car (or its owner) that has not received an update does not necessarily have a problem.

  5. It is not unusual for Tesla cars to have different software at any one time. That is pretty much standard. There are many reasons for this.

  6. At the same time, if you are “frozen” at a particular software version, you are probably not alone. There may be many other cars in exactly the same situation. Unfortunately, most of us are not privy to all the decision-making that goes into Tesla software development and distribution, or necessarily aware of what other drivers are experiencing. And unless you follow software upload tracking sites like Teslascope or Teslafi (which sample their respective customer bases) you may be unaware of the extents of different roll-outs and the varieties of different software versions out there.

  7. The Thread mentioned above was intended to help answer some (not all) questions about late 2021 software updates:
    (a) Determine where you are in the greater scheme of software versions.
    (b) Confirm that you are in a normal "Production Build" or special "FSD Beta Testing" build track. (These are not official names.)
    (c) See what features your car should have (subject to certain restrictions).
    (d) Evaluate the differences in features between the two "branches" (or "tracks").
    (e) Help establish (up to a certain point) whether your car truly should have a particular software version.
    (f) Understand more in general about the way Tesla releases its software updates.

    But Post #1 of that Thread cannot expand forever. Instead, readers are directed to no a tesla app for ongoing information about subsequent Tesla software releases.

  8. Based on TMC Forum comments, there may not be much you can do to speed up or initiate software updates. In this case, patience really is a virtue. However, here are a few tips from TMC commenters:

  9. In your car's (central display) "Software" screen, change the setting for software updates to "Advanced."

  10. If you do not have "Premium Connectivity," be sure your car has extended access to a solid, reliable, WiFi network where it is routinely parked.

  11. Some posters suggest that it is important that the car "sleeps" occasionally. (May not help; can't hurt.)

  12. Since owner's can learn about software updates in at least two ways--from the center display screen (under "Software") and in the Tesla App--it may be helpful to have a reasonably up-to-date Android phone or iPhone with the latest Tesla app version.

  13. If you are in either the Early Access or the FSD Beta Testing programs, and have not received software updates you think you should, you can try contacting Tesla at [email protected] and [email protected], respectively.

  14. Some (not all) have had luck having ("Production Build") software pushed by Tesla Service.
    (a) Use the Tesla App.
    (b) Under "Service" / "Request Service" / "Software" check the "Update" circle.
    (c) Add something like "No software updates - Please check" in an accompanying message.

    Service can apparently check your car remotely, see if software updates have failed, and push an available (non-FSD Beta) update. (See TMC Forum Reference; Post #3.)

  15. If you are applying for or already in the FSD Beta testing program, you can opt out on your car's center display screen (under "Autopilot," I believe) or by contacting the FSD Beta program email (in #13, above).

  16. Use the TMC Forum search function--there are many threads and posts that discuss software updates and downloads. For example, try this Thread: When Do I Get MY FSD Beta Update.

  17. As always, if you have any successful ideas, please share.

I'm also in the same boat, also on a new car so I suspect tps5352's note is what we're seeing. 2021.43.102 pushed last night. The only change I've noticed so far is with the camera view app showing an additional camera in a different layout
This is one of the most frequently asked questions by new owners. They are on a version ending with .101 , .102 , .103, etc. and not getting updates. Not sure what Mynameis is talking about, but maybe they just weren’t aware or maybe they are trolling. This is a very common and well known topic. It’s not really some unknown that people are unsure of. As I mentioned, the service centers will confirm this.

Not trying to add fuel to the fire, but from this data point, when I picked up my MY it was on one software version, and by that evening I had the newest software version out.

The only time I had a delay about getting software quickly was when I opted in for Beta FSD, biggest mistake of my life, I was blackballed for over a month, but that's a whole other story.
