I've never had that issue. You might check that nothing is dislodged/broken in the area of the hinges. Compare the left and right sides for differences. One spring rod may be disconnected or damaged.

Did you by any chance soundproofed it? Adding weight to the trunk lid (ie. dynomat, etc) will cause this.

You may need to add/replace the Hydrolic (sp?) supports on either side of the trunk.

The sedan uses torsion bars, rather than gas shocks. They are #12 and #13 in the diagram below. They may be too fatigued to support the trunk.

What about adding a spring between 13 and 14? Adding more torsion.

The trunk lid blows down in a breeze on my sedan. It ALWAYS catches me by surprise and is a painful reminder. I would have been happier with gas struts, but that ain't how they built it. The trunk lid is very flimsy, and I ain't sure that it would stand up to struts.

Not many flaws in the Yaris sedan, but that is one of them...

I had taken the spoiler off my EVO (to avoid all the silly stop light challenges) and every time I popped the trunk, it would launch up. That's why either there is extra weight on the trunk, or the tension bars are binding, or they are no longer correctly in place. Good luck.

I agree as torsion bars rarely go bad particularly in this type of application although, it is a pssibility.

Ahem, all, may I please direct your attention to the Yaris TSBs thread where I discovered this little gem well after my warranty expired.

To sum it up ... Toyota has known about this issue for a while without telling anyone and we all have bumps on our heads because of it.

The no spoiler one would provide less tension than the spoiler one. If you read the TSB linked above, supposedly there are newer ones which provide more resistance than the original ones.
