If you notice a noise on your vehicle, you are right to be aware of it and take it seriously, although it is plausible that nothing serious will occur, it is also plausible that it is the indication of a more critical repair. A noise that shows up in the trunk of your Toyota Sienna is luckily more a indication of a small manipulation or restoration, rather than a difficult one. To support you in your research, we have chosen to generate this article to present you with the most likely solutions to your problem. First we will see that this trunk noise on your Toyota Sienna can come from built up dirt, the problem can also come from a loose lock and finally, it can even come from a simple rivet that sits inside your bumper.
Noise in the trunk Toyota Sienna : Built up dirt that causes poor closing

We will therefore start with a trunk noise on your Toyota Sienna caused by dirt accumulated on your joints, lock for example. Indeed, it is plausible that on a vehicle that is already a few years old and whose cleaning is not always a priority or that the roads used are not very clean that dirt builds up at the trunk gasket. This problem causes a poor closure of the trunk and a noise that can sound like a crack. To verify if you are in this condition, open the trunk of your Toyota Sienna, check the condition of the gasket that goes around the entire tailgate and clean it with a wet/soap cloth, dry the whole thing and try to close the trunk and take a dentred road to see the improvement. If this is not the case, continue to the other hypotheses that will probably give a solution. It is plausible however that you have a trunk noise on your Toyota Sienna that is connected to other origins such as shock absorbers, do not hesitate to consult this article on the noises at the back of a Toyota Sienna.
Noise in the trunk of my Toyota Sienna : Loose lock, clicking noise
Second possibility, you may also, over time, be the victim of a locking system that became loose. And this is one of the most probably possibilities. Indeed, knowing a trunk noise on your Toyota Sienna is very often connected to this problem. Some solutions are available to you subject to the level of play you have with your lock. The first is that oftentimes the offset is minimal and a simple greasing of the system with thick grease is enough to resolve the issue. Secondly, it is also plausible that you really have a lot of play on your lock and that each time the trunk “jumps”, in which circumstance you would have to strip off the cover that enables access to the lock (inside the trunk). Then, using torx screws, you unscrew the striker attached to the threshold, just push it back a little towards the inside of the trunk and tighten it again. You should verify the centering of the striker in relation to the trunk lock. If after checking out the trunk of your Toyota Sienna closes badly, it means that you have moved it too far, repeat the operation by pushing the striker less.
Noise in my trunk Toyota Sienna : Rivet following plate swap in the trunk/ bumper
Finally, one of the last possibilities. It is that following a license plate swap you were unlucky and that a piece of rivet fell backside your plate. Indeed, when a plate replacement is done, to take out the old one the process used is to drill the existing rivets in order to release the license plate. Sadly, it can happen that part of the rivet falls into the hole of the bumper and it will therefore wander inside the bumper and can trigger an annoying noise. To check that it is this problem you are experiencing, and that you have a trunk noise on your Toyota Sienna linked to a rivet, you will need to verify that it is in the tailgate open it and stir it to discern the noise. If this is your case, you will have to take out the linings from the trunk to remove it. Finally, if it is your bumper, it is in this rarer and more problematic case, you will have to take out the bumper to remove the bits of rivet that are running around.
