I think if the issues you have detailed are enough to spoil your enjoyment of the bass, then it should go back.
I don't see why any of us should accept shoddy workmanship.
I know sometimes it doesn't seem worth all the hassle of returning stuff but this is exactly why dodgy quality control exists.
If Fender or any other manufacturer couldn't shift their less than perfect instruments, then I'm sure they would soon stop being made, quality control would suddenly improve dramatically and there would be a whole lot of very much happier musicians.
Oh for an ideal world.
Anyway hope you get it resolved to your satisfaction.
