Can anyone identify this part, from a 2012 Prius? We had the A/C evaporator replaced about 2 weeks ago, just today we went into the cargo area and found this sitting there, they apparently forgot to put it back. Am I correct guessing it should go around the traction battery somewhere?
Looks like someone separated it from the flat carpeted piece that attaches on top of it. Me, I always just take mine out as one piece. I haven't unclipped the top piece from it. Did they just sort of put the top piece back over your 12-volt battery, hanging by the edges? Do you have a non-original-size-shape battery back there, that this support piece won't fit over? Or does 2012 just have one wide deck board all the way across, instead of separate pieces in those corners like my 2010?
The one in my 2010 liftback looks very much like that (from memory, I haven't run out just now to bring it in or take photos). OP's first photo shows its normal orientation. Third photo shows it upside down, looking at its black-felt-covered 'feet'. The tall feet on the inboard edge rest on the hatch floor sheet metal. The shorter feet rest on the top of the 12-volt battery. The notched tops of the 'buttresses' along the inboard edge support the lip of the big black cargo tray (so, the cargo tray must be taken out first, or at least lifted, before this battery cover can come out). The one in my car is topped with a flat carpeted piece, missing in the OP's photos, of matching height with the carpeted deck board that lies over the cargo tray and serves as the carpeted bottom of the hatch area. I might have to go look more closely at mine to be sure whether the flat carpeted piece can be removed (if it can, I've never done it), leaving the substructure as above, or it's really just a single piece in my 2010, as I have always thought. Nah, being too lazy to stand up and go out to the car ... screenshotting the 2010 and 2012 Prius owners' manuals side-by-side shows they did change it: one piece on the left (2010), "deck board" plus "battery cover" on the right (2012). When I added some fuses and stuff above the battery in my 2010, I did have to pay a bit of attention to not having my added stuff be right where those short felt-padded feet sit on the top of the battery.
