Did I accidently buy a HW3 instead of HW4?

jmutiny1993 | 2026-02-28 21:35 | 26 views

I jsut purchased this used tesla model Y 2023 and the teslaroamer website said it was HW4. I also asked chatgpt and it also said HW4. However a few hours later I asked chatgpt as well as gemini and they are now saying its HW3. I'm freaking out now is this HW3? VIN: 7SAYGDEE4PF875168 EDIT: I called Tesla and they confirmed its HW4

Look at the Pilar camera, does it look redish?

It tells you in the menu. And do you really trust what AI tells you? Lol

I didn't have it delivered yet, just placed the deposit

I have an early July 2023 build from Fremont and it is a hw4, but it was right after they started HW4.

RScottyL 2026-02-28 21:43

Do you know when it was built? North America (Starting **May 2023**): indicate that Tesla began progressively equipping Model Ys manufactured at its Fremont, California factory with HW4 from late May 2023. However, this was a transitional period where HW3 and HW4 vehicles coexisted

Tesla-one-X 2026-02-28 21:43

It also doesn’t matter… HW4.5 rolling out already and will soon be told HW5 needed for true FSD

Ok-Measurement2476 2026-02-28 21:44

What’s the screen look like when in park? Big car on screen (HW4)? Or 1/3 screen small car (HW3)?

Exact-Brush1675 2026-02-28 21:48

I think that vin will have HW4 based on my vin being HW3 and about 100k vehicles earlier I was 3 weeks approx from the switch. But the only way to tell for sure is to have a look in person.

DrowningInManyCats 2026-02-28 21:49

There is no official hw4.5

Mindless-Respect7155 2026-02-28 21:56

Hw 4.5 is not a thing

CapOrganic6868 2026-02-28 22:01

Based on the VIN, should be HW4. The last six of HW4 start from 385XXX

Its easier to look at the turn signal light on the side repeater camera, its not always easy to see the red or sometimes a HW3 camera might look red in the right light

Suspicious-Ad-9695 2026-02-28 22:19

Good to note. How accurate is that?

Tesla-one-X 2026-02-28 22:47

New around here…? Again point holds 4.5 is already out and “needed” for FSD. So whether its HW3 vs 4 is largely irrelevant if goal is being able to use future FSD

DrowningInManyCats 2026-02-28 22:48

Tesla themself said that hw 4.5 was a false label; what points are you talking about? Are you new to keeping up on Tesla news or just trying to belittle me with that comment

Tesla-one-X 2026-02-28 22:50

Sure it’s not an official release. But there are Ys with a new 3 SoC architecture that has higher throughput and processing power. Given HW4 is already 3 years old, new HW is coming if not already discretely in cars but software restricted still

Tesla-one-X 2026-02-28 22:53

Yes, Tesla simply had a “mislabeling” error as the official answer but didn’t deny it was an upgrade or change to the current SoC architecture. Point stands with HW 4.0 over 3 years old that its on its way out. That’s ancient in hardware world. Odd timing they suddenly started labeling “HW 4.0” cars differently, no?

CapOrganic6868 2026-02-28 23:33

Actually, that’s true for Model X I think. Not sure about the other models. But ya, if you have a picture of Software Version Screen, Full Self Driving Computer 4 means HW4

stranger-passing-by 2026-03-02 05:23

This would be for AMD vs Intel

Ok-Measurement2476 2026-03-02 15:24

Thanks for that clarification!

MCay123 2026-03-06 02:49

His last 6 numbers don’t start with 385 but also that’s not true for model Y anyway
