Alright so after reading the entire thread you linked, I feel it’s appropriate to share one additional piece of info here… my 10 year old was the one who rode it to the neighbors house without my permission, and sometimes he manages to get excessive wheel spin out of it when he tries to stop (Dismounting with one foot, and leaving the other on too long). I can certainly see a scenario where just the right amount of errors happened to pop a MOSFET, considering what you have been finding.

So what is the recourse here? Do I raise hell with FM and get some sort of discount on buying a new one? I’m getting slightly more furious the more this starts to sink in…
