Posting this as a PSA for anyone experiencing this issue.
Sept 2021 PLAID Model S
Last occurrence on 2022.4.5.21
Car is now on 2022.12.3.20
I will report back here if it occurs on this or future versions.
I have had instances where all FSD capabilities are suddenly gone, including auto wipers, auto brights, cameras and IC vector visualizations…. Steering wheel reset nor power off solve this issue.
Took it to service.
A firmware bug where the FSD computer gets stuck in a loop waking from sleep.
Bottom line was to make sure it can fully return to sleep (no Sentry mode or summon…)
Just happened a few days ago and this does in fact work.
Here’s the text from my invoice.
Concern: Customer states: Feature Availability & Settings - On April 2, Starting at 5 AM on a long road trip. Cruise control was not available. Spoke with somebody from roadside assistance and they said that it was not a specific sensor or anything like that that it was the FSD computer and then I need to bring it in for service. At that point I had already tried a steering wheel reset with no affect. When we came to our first supercharger stop I did a power off and everything was fine up until today. Everything is dead again but this time I tried a power off with no affect. Also FYI I have received a software update Between the two events. Which means it’s not isolated to the previous version. Here’s a timestamp second time for today. 3:28 PM on April 7
investigated vehicle logs for both time stamps that the customer provided. Found two different issues at both time stamps. the first issue has to do with the FSD beta SYNCHRONOUS_PIPELINE and is under investigation. the confirmed fix has not been released and will be mitigated in a future firmware release. the 2nd issue is that the primary auto pilot computer has booted into an undesirable state when the vehicle started. this will sustain until the vehicles goes through a sleep cycle and it will self recover. this issue is also currently under investigation and does not merit hardware replacement. This issue will be mitigated with a future firmware release.
