My 12 year old son somehow kicked the passenger seat and broke one of the controller. How do I go about repairing this? It broke off and I don't think I can glue it back.

Suncoastparts.com has them for sale pretty cheap

 

if it's just the part which you are holding in your hand you simply buy the replacement part and out it back on - easy. If the part in the seat is broken it's a totally different game.
Something similar happened to me. After figuring out that the replacement part (the one in the seat) costs as much as a used seat, I took the seat out, took the whole panel apart and carefully glued it back together with success.

 

I hope that's not a harbinger of things to come .... my 15 1/2 year old son drove my old 645 CiC into a light pole during his driver's training, so I hope this is worst that your son can do you your ride
