Loose spoiler

I don't know but I'll give a guess. I suspect that the hardware securing the spoiler is inside the panel (s) of the hatch. Once you open that up, it will probably be self evident. Incidently if you have any slight dents, the plastic like material can often be pushed out by hand. There may be some plugs hiding the panel screws.

 

Is it necessary to remove the lower panel in addition to the upper panel to gain access to the spoiler attachment hardware? It looks like the spoiler is located behind the upper panel and removal of the lower panel wouldn't be required.

 

If you cannot get hold of the broken screw, there is a type of screw called an easyout, first you have to drill a small hole in the screw that broke off and then use the easyout screw. On a small screw this can be very difficult. On reassy, use flat/lock washer, do nor overtighten, and use locktight ( a fluid )

 

So HOW did you remove the hatch trim panels ?

 

I struck something and broke the spoiler off when the car was about a month old. The dealer fixed it for free, but it recently happened again. I decided to fix it myself using Cool-Chem, a two part cyanopoxy glue that has 3500 psi strength. I have made a number of "impossible" repairs with this fantastic stuff. (Google Cool-Chem.) The liftback inside trim comes off starting with a small gap on the ~15" piece on the right side. There are 5 bolt heads molded into the spoiler. Remove he bolts, clean up the holes in the spoiler with a Dremel tool and glue the bolt heads back with plenty of Cool-chem, Making sure that the heads are fully recessed. Smooth up the mating surface with a little extra glue if necessary. (It builds up nicely and hardens, fast!) Re-install the spoiler and use Loctite on the nuts. Finally pop the plastic cover parts back into place.

There is no stiffening on the flat metal mating surface on the trunk lid, so the spoiler is something less than "solid".

 

Mine wobbles just from the bass on a good blues track , so it may not even be that bad...

I have a factory spoiler for a 2010 prius for sale. There's two small (less than an inch) scratches on it. I'm selling it for $250. Let me know if your intrested.
