Why Your Car Has a Door Pocket Hiss (Air Leak/Seal Noise)

A hissing noise near the door pocket is usually caused by air entering through worn seals, misaligned door panels, or gaps around weatherstripping, especially at speed.

Potential Causes

Worn or damaged door weatherstripping High Probability

Aged or compressed rubber seals allow air to enter at speed, creating a hiss.

Misaligned door panel or improper fit Medium Probability

Gaps due to panel misalignment can permit air leakage that sounds like hissing.

Loose interior door components Low Probability

Loose parts inside the door cavity can vibrate and mimic a hiss when air flows past at speed.
