A noise that comes out in the trunk of your Ford C-max is luckily more a indicator of a small correction or repair, rather than a difficult one. To help you in your research, we have chosen to write this article to present you with the most likely solutions to your problem.

We will therefore begin with a trunk noise on your Ford C-max generated 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 collects 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 condition, open the trunk of your Ford C-max, check the state 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 impact. 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 Ford C-max that is relating to other sources such as shock absorbers, do not hesitate to have a look to this article on the noises at the back of a Ford C-max.

Second probability, you may also, over time, experience a locking system that became loose. And this is one of the most likely possibilities. Indeed, knowing a trunk noise on your Ford C-max is very frequently relating to this problem. Several solutions are existing 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 good enough to fix 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 strip off the cover that permits 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. Be sure you examine the centering of the striker in regards to the trunk lock. If after checking out the trunk of your Ford C-max closes badly, it means that you have moved it too far, repeat the process by pushing the striker less.
Noise in my trunk Ford C-max : 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 backside your plate. Indeed, when a plate replacement is made, to take off the old one the procedure 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 cause an annoying noise. To check that it is this problem you are experiencing, and that you have a trunk noise on your Ford C-max linked to a rivet, you will need to examine that it is in the tailgate open it and stir it to specify 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 disturbing case, you will have to take off the bumper to remove the bits of rivet that are running around.
