Same issues here Refresh Model S LR , and tbh, they start during the preconditioning when going to a supercharger, and they just get worse during/after supercharging.
After the first incident, I just dismissed it and drove home.
After the second incident, I was on the phone with roadside assistance and they just told me to reboot (I didn't know about the scroll wheel reboot prior to this incident). Took the car into service center and they said a firmware update would fix it.
I stopped supercharging for a 2 months, waiting for the firmware update. I'm now on 2022.4.5.21 and went to supercharge a day ago, and then all the nonsense started happening all over again. Flashing lights, frozen/laggy cameras, frozen/laggy FSD animations.
Took into the service center and they said they couldn't reproduce the issue, but my invoice shows that 2 things were replaced:
- Retrofit HCU Wake-Up Wire ASY, HARN, FRUNK SWITCH GND, OVERLAY, MS (17317861-00-B)
- Battery Controller ASY BATTERY CONTROLLER, GEN 1 (1588205-04-B)
Fingers crossed the next time I go to supercharge it won't act up on me.
