Rattle in driver's B pillar (2024 LC)

[TakaraLC]

I have a new suspect for this noise. At least in my case, the noise seems to be coming from the fuel door. Fuel door is rather flimsy and is made out of thin sheet metal. It has two small anti-vibration rubber stoppers inside, but at least in my case, they are short and do not actually make contact with the body, and hance the fuel door rattles very easily. I can easily shake the fuel door with my hand when it is close.

I realized all this because when I close the rear left passenger door, I was hearing a metallic rattle noise that sounded very similar to what I though I was hearing from the B-pillar. If I close the rear door while firmly holding the fuel door, it doesn't rattle and there is no metallic noise from it.

I haven't though how to fix it yet, but perhaps I can put rubber extendedness to the body side so that the anti-vibration stoppers actually make contact with the body, and hopefully keep the fuel door in place.

You might use some of those small self adhesive, felt dots/pads they sell at hobby stores, to confirm your theory and if they eliminate the rattle fab a more permanent solution.

Yeah I am thinking something similar with 1/4 in thick adessive foam tape.

I was thinking more like these....

Ordered these. At the meantime, tried adding small cutouts of foam tape to where rubber stoppers on fuel door meet the body, and it fixed the noise in my case.

I guess, fuel door may be the reason why most owners report hearing this noise on driver side, but almost never passenger side.

Good find, I never would have thought of a fuel door rattle transferring into the cabin area. The fuel door is very complex for what it is....... I've attached the PDFs for you to explore.
