05' Accent 5th gear pop out?

Hi all,
I have an 05 Accent with 35000 miles and it has recently developed
5th gear pop out. The car has not been abused and all maintnance is up
to date. It happens in 5th gear when decelerating at any speed. The
car is going into the dealer tomarrow and they are fixing it, but I
would like to know if this has happened to anyone else and what caused
it.
Thanks
Bill

 

The most likely cause of this problem is some combination of wear between
the 5-R shift hub and fifth gear. These are both inside the end cover of
the transmission, so the dealer may be able to repair without removing the
transmission and doing an overhaul.

 

Update,
The dealer said that 5th was poping out because of a bolt stripping in
the gear box. They are still working on it, and haven't told me what
caused the problem yet.
