A noise that shows up in the trunk of your Mazda CX 3 is thankfully more a sign of a small correction or restoration, rather than a difficult one. To help you in your research, we have chosen to generate this article to present you with the most likely solutions to your problem.

Noise in the trunk Mazda CX 3 : Accumulated dirt that triggers poor closing

We will therefore begin with a trunk noise on your Mazda CX 3 caused by dirt accumulated on your joints, lock for example. Indeed, it is plausible that on a automobile that is already a few years old and whose cleaning is not always a top priority or that the roads used are not very clean that dirt builds up at the trunk gasket. This problem triggers a poor closure of the trunk and a noise that can sound like a crack. To examine if you are in this scenario, open the trunk of your Mazda CX 3, verify the condition of the gasket that runs 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 difference. 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 Mazda CX 3 that is related to other origins such as shock absorbers, do not hesitate to have a look to this article on the noises at the back of a Mazda CX 3.

Second probability, you may also, over time, knowledge a locking system that became loose. And this is one of the most probably possibilities. Indeed, knowing a trunk noise on your Mazda CX 3 is very often related to this problem. Different solutions are available to you depending on the level of play you have with your lock. The first is that quite often the offset is minimal and a simple greasing of the system with thick grease is more than enough to eliminate the problem. 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 case you would have to take out the cover that permits access to the lock (inside the trunk). Then, using torx screws, you unscrew the striker attached to the threshold, simply push it back a little towards the inside of the trunk and tighten it again. Don’t forget to examine the centering of the striker in relation to the trunk lock. If after examining the trunk of your Mazda CX 3 closes badly, it means that you have moved it too far, repeat the process by pushing the striker less.
Noise in my trunk Mazda CX 3 : Rivet following plate change in the trunk/ bumper
Finally, one of the last possibilities. It is that following a license plate change you were unlucky and that a piece of rivet fell behind your plate. Indeed, when a plate change is made, to remove the old one the strategy used is to drill the existing rivets to be able to released 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 create an annoying noise. To check that it is this problem you are experiencing, and that you have a trunk noise on your Mazda CX 3 linked to a rivet, you will need to examine that it is in the tailgate open it and stir it to identify 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 remove the bumper to remove the bits of rivet that are running around.
