Trunk closing problem

It's beeping, or no?

Also, watch starting around 0:45 of first video here:

He talks about purposely clicking the hatch latch so that it won't shut. Maybe?

 

it's a double lock, so can be hooked but not closed all the way. try pushing on it while someone is sitting in the drivers seat.
make sure there is nothing interfering with the latch

 

Bisco is correct. It can seem like it’s closed but sometime it can fool you. The hatch needs to be moderately assisted so that the secondary, main latch is tripped.

 

I had a problem with the rubber trim and that prevented that last mm of closure or whatever is required. I just pushed the rubber trim back in (the problem was obvious once spotted) and it was OK.

 

This is how I fixed our 2012 Prius V latch problem. Trunk would not close. Second latch would not turn the light off on the dash. Weather stripping seemed swollen or hard and there is no adjustment on the latch for it. I popped out the plastic handle for lowering the trunk lid and looked inside. I took out the four fasteners that hold the latch mechanism. I pushed the latch mechanism back and used my dremmel tool to elongate the screw holes towards the ground so the mechanism would not hold the door so tight. Lid now closes properly.
