Well, they certainly didn't on mine. I took it to a tech - a member here - to look at and we decided in cutting and installing a new nut to keep the G string on the board and to get it closer to the pole pieces, which is far from ideal on a bass at that price point. OK, this was a fair while back (2010ish) and I imagine they got on top of it, but I remember at the time there were a few people here and on TB said they'd had similar issues.
But yes, they are otherwise beautifully designed and engineered instruments, it always seemed very odd that despite the evident quality in 99% of the instrument, that more than a few of them had this issue.
