Hold off on Any upgades. MCU3 upgrade might be coming
With v11, Tesla officially now calls all MCU2 cars with with a vertical display "legacy". Including the ones manufactured early in 2021.
Does not really make MCU2 upgrade that compelling...

Hold off on Any upgades. MCU3 upgrade might be coming
I wish you the best, but I'm guessing the answer will be "there is no fix at this time, the only fix is to buy MCU2".Car in service. Team at the service center was professional and understood the issue.
Now I can only hope they will do the right thing and fix it - even if it might require some extra effort on their side as they likely do not have any standard operating practices for it.
Wish me luck
Not surprising. Legal action is the only path forward.Tesla representative CONFIRMED that FSD/HW3 + MCU1 cars record broken dashcam video
My car has been in service center for diagnosis Monday-Friday this week. Their representative just confirmed the following on phone:
In short, Tesla confirmed that:
- Issue is CPU usage in MCU1 + HW3 FSD computer configuration
- Multiple Tesla customers have the same issue
- Tesla engineering team is investigating the issue and planning for a solution
- They do not have any estimate when that investigation might complete. I specifically asked if that would be "days or years or something in between" and the service representative said that he do not know
- Tesla engineer confirmed during my visit to the service center that installation of MCU2 would solve the issue. I asked if Tesla would go ahead and solve the issue by installing MCU2 now that they know that it would fix the issue, they refused. Instead they want to continue investigating the issue (without any timeline) and decide solution after that.
- When asked to speak with someone who would be authorized to decide on fixing the issue, Tesla representative initially refused. When I asked ifs the only way to get them to fix this (warranty) issue is taking legal action, they confirmed that this would be my choice. Later in the call they said that I could speak with customer service representative, but said that they would just be repeating the same above position.
With this, only ways Tesla offer for getting them to honor their warranty (to fix dashcam they broke with FSD) is either 1) take legal action, or 2) purchase MCU2 and FM tuner for $2000 or 3) wait until they figure out a solution. With their track record with FSD delivery and low priority they have for MCU1, wait may be literally endless.
- Installation of FSD computer in MCU1 car will break dashcam
- It is a warranty issue (dashcam is covered under warranty)
- They are investigating how to fix the issue, but are not committing to any timeline for actually fixing it
- They refuse to fix the issue by installing MCU2 even when they know that it would solve the issue
I would encourage everyone with FSD + MCU1 to contact their service center, discuss the issue, and share here what they learn from those conversations.
My service center hates me. But I have the managers cell phone now, so that's kind of cool. No more texting the "techs" that keep calling it "MCC1."Tesla representative CONFIRMED that FSD/HW3 + MCU1 cars record broken dashcam video"
I would encourage everyone with FSD + MCU1 to contact their service center, discuss the issue, and share here what they learn from those conversations.
Upon reviewing dashcam/sentry mode footage, confirmed this is a known issue with Tegra MCU configured with DAS HW3 due to heavy CPU usage. No replacement of hardware is required as of right now. Tesla is aware of the issue and is currently under investigation.
Nice! This would be the first refund I've heard of. Wouldn't be surprised if they NDA'd you before you get any money back. Could open the floodgate for $3k+ refunds for everyone that's being slow rolled on FSD.When picking up the car, I finally got to speak with the service center manager. He promised me a full refund for FSD.

Are they just refunding the FSD portion so you’ll have only EAP?Too late for that... (was not part of the agreement)
That said, I'll wait for the payment to clear until putting the matter to rest.
Are they just refunding the FSD portion so you’ll have only EAP?
Did you pay taxes on the $5000 Purchase cost?. What about interest paid (if you had a loan on that sum?) Based on your understanding are the SC's now authorized to do refunds?That was the agreement. Which is fair: EAP was delivered and FSD was not.
I paid $5,000 for FSD and EAP each. Thus the refund is $5,000.

Wouldn’t it be easier if they offered you a free upgrade to MCU2? Or is that not an acceptable solution? Not that they’d offer that …When picking up the car, I finally got to speak with the service center manager. He promised me a full refund for FSD.
With this, they will be able to fix Dashcam either by downgrading AP back to HW2.5 or maybe their engineering really finds a software fix and no service center visit it needed. I’ll see how the process goes.
Overall, I find this resolution acceptable. No need for taking legal action to resolve the issue.

Here's hoping that Tesla Engineering do find the cause of CPU spiking before then, as there's a slim potential for software-based load optimisation).
