There was a TSB requiring the tech to reposition the
striker by enlarging the bolt holes to allow for better alignment. (toyota cannot reccomend hitting it with a BFH). Instead of taping it, look to see how it fits into the slot on the seatback. It may only need to be adjusted a few mm up or down which can be done by a few medium taps with a heavy hammer. Adjust until it fits right in the middle of the seatback channel you should find the seat will close and release a lot easier once you'r done
I did this a few months ago and the seats are rattle free.
Good luck
