Confused about model 3 updates and software releases.


Apr 12, 2021
Most of us are waiting in atispation for V11 although no official confirmation of when, however being new to owning a Tesla i'm slightly confused on the version I should have installed.

My vehicle is on advance software updates however as of today it's still showing the latest version is 2021.4.18.
This is for a M3P 2021 (China manafactured model) made for the UK market.

Can anyone confirm this is correct latest version please as i'm aware there have been many other versions rolled out since although I guess it depends on the Geo and model?

Thanks in advance

There is no 'correct' version for a particular car.

Tesla release different versions to different cars over a period of time. Its just that this time there are even more versions and a longer period of time. Sometimes its obvious why certain cars get targeted with particular releases, Model, region, FSD etc, but other times it just seems to be random.

Something like TeslaFi firmware tracker shows the spread of versions across the TeslaFi fleet which is large enough to be a good representative sample. You do seem to be a bit off the curve if you are on 2021.4.18 - most common release is 2021.4.18.2 with just under 50%.

In my experience, standard/advanced only has a minimal impact on software availability. My best description is that standard may give a slight delay in software updates, but not always.

There are also early access programs (EAP) and the very limited FSD beta. EAP members do not usually make their cars particularly visible to firmware trackers, but non Tesla employee FSD beta participants seem to be highly visible on social media.

It's sort of a moot point as you can only update the car if the car tells you there is an update available.
Here's a list of versions:

I'm on 2021.4.18.2, but I've got a Fremont car not MIC, so there may be a difference there.

According to TeslaFi, over half the Model 3's are on 2021.4.18.x at the moment, including mine.


The logic of who gets offered updates isn't worth trying to follow, Tesla select cars based on so many different factor, including random selection of a percentage to move to a different version. I would say it looks likely that 2021.12.25.6 looks likely to be our next step, perhaps in over the next week.

Mine is a March 2020 LR with FSD and on 4.18.11.
for the last few months, there have been around 2K cars following a different path to the majority. Most are FSD.
However, in the last few weeks, updates have gone haywire with almost a dozen different versions being introduced.
I can only assume that these are fixing model specific bugs with at least some sorting heat pump issues on newer models.
