Why Your Sunroof Makes a Gurgling or Hissing Noise

A gurgling or hissing sound from a sunroof often stems from air flow or seal issues around the sunroof assembly, leading to uncomfortable wind noise or leakage sounds.

Potential Causes

Air flow through imperfect seals High Probability

Worn, misaligned or hardened weatherstripping around the sunroof can allow turbulent air entry causing hiss or gurgle noise.

Wind noise due to aerodynamics Medium Probability

Airflow across the sunroof opening or slight gaps can generate aeroacoustic noise perceived as a gurgle or hiss.

Debris in sunroof track Medium Probability

Dirt or small debris in the sunroof track can disrupt seal contact and airflow, causing intermittent noise.

Diagnostic Steps

Visual inspection of seals

Examine the sunroof weatherstripping and seals for cracks, gaps or wear.
Clean sunroof tracks

Remove debris from sunroof tracks and drainage channels to ensure proper seating of the sunroof.
Check sunroof alignment

Operate the sunroof and check if it aligns flush with the roof; adjust if needed to improve seal contact.
