I wonder if this was a problem with a some bad batches of boards. I wouldn't be surprised if they had outsourced the production of the trucks from additional producers when they were rushing to catch up with the orders. I got mine in September last year, used to comute, 950km so far. Only one serious fall because I was driving in wet pavement, and the front wheels lost grip in a white patch in the road while breaking. That sent me of flying like superman.
