    Not sure if anyone has encountered this?

    Trunk won't close unless I slam it down pretty hard. I think the the previous owner has backed into something or something has collided with the spoiler which caused the trunk lid to deform slightly and in turn moved up the latch somehow.

    If you remove the rubber cover on the latch you can see how the mechanism works. When the top of the latch comes into the contact with the bar on the bottom of the trunk latch. it pushes up this switch which is tensioned by this copper spring. The spring seems to be working fine. I think it might be the bar does not come up into the switch far enough when the trunk is closed normally.

    The other thing is the black button on the bottom of the lid latch area. When the trunk comes down it turns off the trunk light. It looks like it does not come down far enough to depress the button. And the right side seems to be longer which is a bit strange, since the button is on the left. This leaves the light on and drains the aux battery after 1 or 2 days.

    I just removed the bulb for now, but it doesn't look like either the bottom portion of the latch or the top portion of the latch is adjustable. Could replace the whole upper latch, but it doesn't look it will help.

    Saw some threads for the gen2 where the adjusted the weather strip for this same issue, but removing my weather strip doesn't seem to make a difference

    Looks to me like the plastic that's getting beat to death on the mechanism is not a good situation I would think that would be enough to throw the latch off a good little bit You don't think you can just get another mechanical side doesn't it just unbolt or take the plastic off of all of it and then you can slide the piece that was covered in the plastic I think you can loosen the bolts and move it up and down a little bit right? So put it all the way up to make up for missing the plastic so it'll close down tighter would be my gas but half the plastic gone and the wear spots like that and having the rest sitting there doesn't seem like that would work very well.

    Could it be one of the blankets you wrapped the body in? Maybe covering the latch. And rigor mortis could be kicking the light switch. I had one mess with my tailights before.

    I thought somebody on this list figured out that a Corolla with the inside handle release would fit this generation one Prius trunk but I could be wrong.

    I took 2 bolts off of the top and bottom each. It doesn't look adjustable. Just a 4 holes, no sliding/wiggle room on each bracket.

    Hey, IDK, a tarp? The carpet you cut out of the floor?

    Not sure what you are referring to. If you look at the top and bottom though it doesn't come into contact with the lining. Just the plastic weatherstrip which I tried to attempt closing after removing and got the same result.

    A new mechanism might help with the latch switch but don't think it will help with depressing the light switch. That seems more like positioning of the entire mechanism.

    The latch seems to work fine with using a screwdriver to simulate a trunk closure. See video link:

    It was a dumb joke, insinuating that you were carrying a dead body in your trunk and whatever you had it wrapped up in was blocking the latch. And a second joke, when I insinuated that a dead body I was carrying broke my tailights.

    Yes, I need new material, but this is a tough crowd too.

    LOL i thought you were about the body of the car and rigor mortis of the gears of the locking mechanism or something.

    That looks almost exactly like my 02 Corolla latch assembly this is a car I've had since '03 and have done everything to this car it is never been in for service anywhere and still like a brand new car today other than the white paint is fading everything on the vehicle works and the trunk latch mechanism from inside the vehicle like laying in the trunk looks exactly like this Prius I don't have a Prius sedan to go out and play with I wanted one for years then I guess I got smart You never want the first of anything. But anyway I would be shocked if it wasn't a Corolla piece because Toyota's pretty good about that stuff they don't re-engineer a new piece just because very similar to the way Volkswagen works they try and use what they have already if at all possible. I would think a Corolla inside trunk latch assembly would be about as free as you can get from wherever you get.

    That might have been taken at an angle. I've tried to take a more direct shot here. This is about the closest I could do while keeping both the top and bottom in the shot. It looks pretty straight here.

    OK, let's try this again; perhaps I didn't make it clear. Take another look at the photo in the link https://attachments.priuschat.com/attachment-files/2023/09/242268_PXL_20230901_215306204.jpg . Do you see how the light switch (the black button) bracket does not line up parallel to the striker plate, but is cocked out an about a 30º angle to it? If that bracket/switch were in line with the striker, the latch plate (specifically, the left side of the forked assembly) would then make direct contact with it, As it now stands, it's only going to have a glancing contact it with it, and I'm surmising that said glancing contact isn't going to depress the switch far enough to shut off the light. Can you somehow bend the switch bracket over to the right so that it lines up with the striker?

    Ah, I see what you mean, thanks. I thought it was stock like that. I assume yours is parallel? I took off the bottom striker plate to take a closer look. I wonder if it could have been bent when spoiler was impacted.

    There is a hole, albert much larger and round, where the protruding tab could go into i guess.

    Good eye trombone. I bent the bracket back and now it turns off the light! Here is the before/after.

    I'm still having to slam the trunk to close it though. Now I'm thinking the bracket was bent because of the previous owner slamming the trunk again and again.

    Good, you solved it. Yes, the parallel arrangement is original. Hard to see how it got bent out like yours, because the switch bracket is staked to the striker plate in two places. Almost looks like somebody or something intentionally altered it. But all's well that ends well.

    Might try to bend the trunk somehow or maybe install a new bracket for the slamming thing. Not sure what else to try for that.
