Why Your Cup Tray or Console Makes a Small Humming Noise

A small humming or buzz from the cup tray area is typically due to loose interior components or vibration-related noise in the center console rather than an engine or drive system fault.

Potential Causes

Loose cup holder components High Probability

The interior cup tray or spring-loaded arms can vibrate or hum due to loose clips, plastic tabs, or weak retaining springs that resonate when driving over minor bumps or road surface noise. This is a common interior noise issue unrelated to mechanical failure.

Diagnostic Steps

Verify source of noise

Drive at low speed and lightly tap cup tray area to see if noise changes or stops; remove all items from cup holders to rule out object-induced noise.
Inspect cup holder inserts

Check for loose or worn springs/clips and consider adding padding (felt or silicone) to reduce movement between parts.
Check surrounding trim fitment

Gently press on dashboard/console trim around the cup tray to identify loose panels or rattles; tighten clips or fasteners as needed.
Remove and examine A/C ducting behind the cup tray

If accessible, remove the cup tray trim to inspect and secure loose A/C ducts or internal components that may vibrate.
