All cars do this eventually. As the motor and transmission mounts wear, more vibrations are transferred to the cabin. Couple this with aging plastics and a low rpm, queue annoying rattle. Unless you really want to go replace all the mounts, tune up the engine, and foam tape the entire dash, best to just shift to neutral if stopped for long enough.

 

Thank you, the noise is loud and rhythmic. I have a video that contains the audio but am not sure if it’s possible to share on this site.

 

Interior or exterior? Plastic or metallic? If exterior and metallic, exhaust heat shields are a good place to start. Interior and plastic are much harder to track down and are often caused by drivetrain vibrations.
