Boost module has one more saving feature you might not have realized.
My 3 glitched out last week at a mall parking lot. When I pulled in, I realized the turn signal sound was not turning off even though I had cancelled them.
Even after I parked, they were still going off.
I ran my errands and came back out to my car still on. (HVAC, unlocked...) and signal sounds still going.
I tried to turn off the vehicle through the infotainment. Tried resetting computer with the two wheels. Nothing.
After first shut down, the screen would stay black except when the door was open.
Tesla roadside just asked me to do those two resets. Car would drive but in a limp mode, could barely get up to speed in the parking lot.
Roadside ended up ordering a tow.
Then I realized the boost module has a hard reset. Went into the app, hard reset and everything was good after a cycle.
I will not forget that is an option after this. I was even contemplating just disconnecting the 12v to force a reset.
