On the door latches I'm not sure, its just not catching. If it does catch it only shuts half way. It's intermittent for sure, it can not latch 5 times in a row or semi latch and then finally latch. Or it'll latch first try for a few times in a row. For the back it stays "locked" unless i pull up on the external lock and try to open the door handle a few times then it'll unlock.
