I had a onewheel that would occasionally just stop. The first time I was going at 15 mph and fortunately came away with only a few scrapes.

I sent it in and they fixed it. This is their explanation which I don't know that I fully believe:

Our engineers completed the repairs on your board! They found that the power button had broken which led to damage to the controller circuit board. Both have been replaced under warranty for you. After your board passed our post-op testings it was picked up by FedEx!
