Happened to me as well just a few days ago, XR w. Gemini. Was going slow, under ten mph, board bricked and shut off three times in maybe 10 minutes. Ate the tasty NorCal pavement twice and gave up the third time, no way I'm getting back on it before it gets properly checked.
Absolutely no issues before this incident, the board has 450 easy commute miles on it.
Still waiting on the customer service to respond. Sad panda.
