Why Your Rear Hatch Hisses in the Rain (Causes & Fixes)

A hissing noise from the rear hatch in rain often stems from water or air entering through compromised hatch weather seals or gaps in the hatch closure area.

Potential Causes

Compromised weatherstripping seal on rear hatch High Probability

Worn or misaligned weatherstripping allows rainwater and air to penetrate gaps creating a hissing/wind noise; seals dry or shrink over time leading to gaps. Weatherstripping is integral to sealing elements from water and noise.

Clogged drain or blocked water path around hatch Low Probability

Water may pool and move along unintended paths, forcing air and causing abnormal sound during rain. Clearing drains resolves flow. ()
