Why Your Sunroof Makes a Lip Pop Sound (Causes & Fixes)

Sunroof lip popping noises often result from mechanical binding, worn seals, debris in tracks, or misalignment of the sliding roof components. Timely diagnosis helps prevent further damage.

Potential Causes

Dry or insufficient lubrication in sunroof tracks High Probability

Lack of proper grease causes binding and popping as the sunroof moves along its tracks.

Worn or hardened rubber seals Medium Probability

Aged or hardened seals catch and release during travel or operation, producing pop sounds.

Debris caught in sunroof tracks Medium Probability

Leaves, grit or small objects in the track can intermittently catch and cause a popping noise when the sunroof moves.

Misaligned sunroof panel Low Probability

If the glass panel or frame shifts out of correct alignment, it may bind and pop over detents.

Diagnostic Steps

Visual inspection of tracks and seals

Open the sunroof and inspect for visible debris, damaged seals, or dry metal surfaces.
Clean and lubricate tracks

Remove foreign objects from sunroof tracks and apply appropriate automotive-grade lubricant.
Check seal condition

Examine rubber seals for cracks, hardening, or deformation; replace if necessary.
Inspect panel alignment
