Why Your Sunroof Latch Squeals (And How to Fix It)

A squealing sound from the sunroof latch usually stems from mechanical friction, wear or misalignment in the sunroof components. Addressing lubrication and alignment typically reduces the noise.

Potential Causes

Dry or worn sunroof latch/track High Probability

Lack of lubrication or wear in the latch or sliding tracks causes metal/plastic friction leading to squeal.

Misaligned sunroof panel Medium Probability

Misalignment of the sunroof panel relative to frame can cause contact and squealing sounds.

Worn weatherstrip/seals Medium Probability

Deteriorated seals can allow movement or vibration at the latch leading to squeal.

Diagnostic Steps

    Check for visible wear or debris on latch, tracks and seals.

  2. Lubricate latch and sliding parts

    Apply appropriate lubricant to latch points and rails.

  3. Check alignment of sunroof
