What is the cause of the trunk rattling noise in the new Fit?

The cause of the trunk rattling noise in the new Fit is a faulty sealing strip, and it is recommended to replace the sealing strip. The new Fit is a compact car under Honda, with body dimensions of 4065mm in length, 1695mm in width, and 1525mm in height, and a wheelbase of 2530mm. This car is equipped with a 1.5-liter naturally aspirated engine across the entire lineup, which has a maximum torque of 155 Nm. This engine can deliver maximum power at 6600 rpm and maximum torque at 4600 rpm. The front suspension of the new Fit uses a MacPherson independent suspension, while the rear suspension employs a torsion beam non-independent suspension. Compact cars typically use torsion beams for the rear suspension, as this setup helps to expand rear passenger space and trunk space—both of which are very important for small cars.

After driving many cars, I've found that rattling noises in the trunk of the new Fit are quite common, usually caused by minor issues. If the trunk latch isn't securely fastened, it tends to produce a rattling sound, especially on bumpy roads where shaking intensifies. Loose items inside, such as an unfastened spare tire screw or a toolbox moving around, are also common culprits. Improperly folded rear seats or unsecured buckles can create squeaking noises. Additionally, thermal expansion of plastic parts causing increased gaps and friction sounds are included. I recommend periodically checking these areas—adding rubber pads or tightening screws can help alleviate the issue, as trunk noises can be both annoying and distracting while driving.

When repairing a new Fit with trunk rattling, it's often due to worn locking mechanisms or improper installation. Insufficient hinge lubrication causes squeaking, while loose rear compartment panels frequently rattle. Unfastened or aged shock absorber mounting bolts amplify vibration-induced resonance noise. Improperly secured spare tire wells or heavy loads deforming the compartment also contribute. Repairs are straightforward - adjusting or replacing clips typically resolves it within half an hour. Delaying may worsen wear or spread noise to adjacent components.

The trunk of my Fit always makes annoying rattling noises, affecting the mood of our family trips. Usually, the issues come from small things: shopping bags rolling around and hitting the interior walls, or loose small storage compartments for miscellaneous items, especially when children's toys are left unsecured and cause a ruckus. Aged and cracked trunk seal strips causing wind friction noise are often overlooked. A simple solution is to empty the trunk to see if the noise disappears, then use foam tape to seal gaps or replace the seal strip for an easy and safe fix.
