Pressing on the back seat behind passenger
 

If I press on the back seat behind the passenger seat, there is an annoying popping sound like a plastic bottle being pressed on. Its annoying when someone is sitting and moving lol...

Any resolution?

remove seat and figure out what's causing the problem?

I would start with #3, #5, and #6 in that order.
#3. Fold the rear seat and then slam it back.
#5. See here.
#6. See here.

Thanks, but I rather get Toyota to do that ;D

I saw your problem and I have it too, but this is different. That only when you press on it...

Then just bring it into the dealership? Is most likely something loose somewhere.

#1 through #6 I put there are not related to the noise I talk about in that thread. I put them there to say that I'm not talking about those noises. I got information about #5 from a guy who was saying he gets noise either when someone sits in the back seat or press the bottom of the folding back seat with his hand. That's very similar to what you describe. That's why I said #5 seems like it, but I said to try #3 first since that's so easy to do and that can be the cause too.

Oh I follow you now. Alright, I will bring it to Toyota and mention the following problems diagnostics. Thanks :D
