While there have been continues updates to FSD for cars with HW4, there has not been any updates for HW3 vehicles in quite a while

I dont see much activity with either HW3 or HW4. My HW3 cars got updated to their current version in late February. Around that same time, my HW4 car got 13.2.8. Since then HW4 has had a single update to 13.2.9.

I notice increased problems with FSD performance for both HW3 and HW4 despite the version number remaining the same.

 

FSD super computer at Austin may be overloaded… lag, lag, lag…

 

There really have been few updates for HW4 either, actually pretty much the same as HW3.

As has happened many times, we are in a lull between major updates.
I suspect that the team has been busy with the robotaxi release, and as soon as it settles down, that release will get targeted to the fleet, including HW3.

None of the vehicles have gotten major updates in months.

 

While there have been continues updates to FSD for cars with HW4, there has not been any updates for HW3 vehicles in quite a while.

FSD for HW3 was last updated from 12.6.3 to 12.6.4 on 17-Feb-2025.

FSD for HW3 was last updated from 13.2.8 to 13.2.9 on 11-May-2025.

Overall, FSD updates for the general public for both hardware versions have been few and far between in 2025 so far.

I believe @garsh is correct in that Tesla is using nearly all of their computing resources to focus on improving their robotaxi service as quickly as possible now that FSD (supervised) for HW3 and HW4 has become "good enough" for many users for now.

Is support for HW3 dead now, with no updates for the foreseeable future? If so, they better be working on the HW4 that can be retrofitted to HW3 cars. (Will not be holding my breath on that one either).

The chance of HW3 being unable to support unsupervised FSD is increasing exponentially over time and I doubt Tesla has made much progress on a retrofit since they don't yet know for sure which hardware version will be sufficient for generalized autonomy.

I doubt HW4 will and believe that HW5 will be the minimum required at this point, but there's no point in developing a complete solution for a retrofit when Tesla doesn't know if the retrofit will be sufficient. It would be disastrous to retrofit HW3 to HW4 then find out HW5 or better is required and have to retrofit again.

The reality is I wouldn't expect to hear much more about a retrofit until unsupervised FSD rolls out everywhere - and I expect that timeline to be closer to years than months.

I'm hopeful and would love to be pleasantly surprised to learn that my HW4 vehicle will be able to drive me around anywhere I want to go without my supervision, but I'm also tempering my expectations with realism.

 

I hate to argue but I have had excellent luck with FSD on my newer Y with Hardware 4. And for a while last month received updates every couple weeks. Did you set your request to frequent updates?

 

There's always one in the bunch! LOL!

 

I think I've had at least once a month with my h.W three

 

Elon promised retrofit from HW3 to HW4 for people who purchased FSD. No specific timeline and this hardware is not yet available or planned and it seems that will not happen until HW4 is tested and perfected in several areas and they are ready to release true FSD. This will not happen till HW5 is out. So we are in a wait and see situation. As FSD owners with HW3 we need to demand the retrofit or some other compensation if that route is not feasible.

 

Elon promised retrofit from HW3 to HW4 for people who purchased FSD.

There are two conditions:

1. Only if HW3 ends up being not capable of implementing FSD, and...
2. Only if you have purchased FSD. Subscribing doesn't count.
