If you detect a noise on your car, you are right to be careful of it and take it seriously, although it is plausible that nothing serious will occur, it is also plausible that it is the sign of a more important restoration. A noise that occurs in the trunk of your Nissan Micra is thankfully more a sign of a small adjustment or service, rather than a difficult one. To help you in your research, we have chosen to produce this article to present you with the most likely solutions to your issue.

We will therefore start with a trunk noise on your Nissan Micra induced by dirt accumulated on your joints, lock for example. In fact, it is plausible that on a car 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 issue triggers a poor closure of the trunk and a noise that can sound like a crack. To verify if you are in this situation, open the trunk of your Nissan Micra, 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 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 Nissan Micra that is related to other sources such as shock absorbers, do not hesitate to read this article on the noises at the back of a Nissan Micra.

Second possibility, you may also, over time, knowledge a locking system that became loose. And this is one of the most probably alternatives. In fact, knowing a trunk noise on your Nissan Micra is very often related to this issue. Some solutions are available to you according to the level of play you have with your lock. The first is that occasionally the offset is minimal and a simple greasing of the system with thick grease is good enough to fix the trouble. 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 strip off the cover that will allow 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. Be sure you verify the centering of the striker in regards to the trunk lock. If after verifying the trunk of your Nissan Micra closes badly, it means that you have moved it too far, replicate the operation by pushing the striker less.
Noise in my trunk Nissan Micra : 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. In fact, when a plate swap is made, to take out the old one the procedure used is to drill the existing rivets to be able to put out 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 cause an annoying noise. To check that it is this problem you are experiencing, and that you have a trunk noise on your Nissan Micra 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 remove 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.
