I know this seems like just another creaking/rattling noise post, but I've searched everywhere and haven't come across anyone with a similar issue (it's not any of the common issues, like upper control arms or rear seat latches).
I have a 2018 Model 3 Performance (stealth), and I've been getting a creaking noise (sounds like metal flexing) whenever I let off the throttle completely at around 40mph, and sometimes when accelerating from around 30mph. It's more audible with the rear seats down, but I can hear it with the seats up too. It's coming from the trunk area.
I had a friend drive around while I was in the trunk listening for it, and we found that it was coming from the "pocket" on the left side of the trunk, near the rear. After removing all the carpets from the trunk and stripping everything down to bare metal, the noise became louder.
I've tried diagnosing with a ChassisEAR kit and found that it was loudest when the mic was clipped to the welding flange on the rear driver's side wheel well inside the trunk. I also checked all suspension and subframe bushings (clipped mics to subframe bolts and suspension control arms), and it wasn't audible at all in any of those areas except when the mic was clipped to the rear left strut top-hat, but the noise was much quieter than when it was clipped to the inside of the trunk. We've tried pressing against pretty much every visible metal panel in the trunk and couldn't feel anything actually flexing or moving around, and the noise was still present. It's definitely coming from a lower area rather than the rear shelf or roof of the trunk.
Unfortunately, I have aftermarket suspension components (MPP coilovers, rear camber arms, sway bars & end links) so Tesla SC wouldn't even touch my car, even though I told them the noise was coming from inside the trunk. If anyone's experienced a similar issue, any help would be greatly appreciated!
