Why Your Car Makes a Hissing Sound at the Door Gap (Causes & Fixes)

A hissing or whistling sound near door gaps while driving is usually caused by air leaks due to worn or misaligned door seals/weatherstripping, allowing wind noise into the cabin.

Potential Causes

Worn or damaged door weatherstripping High Probability

Over time, rubber seals shrink, crack or pull away from the door jamb, leaving gaps that let wind air hiss through at speed.

Misaligned door or latch Medium Probability

Door not closing flush due to hinge sag or latch misalignment can create gaps causing a hissing noise as air flows past.

Damaged door frame/molding Low Probability

Bends or damage to the door or frame can prevent proper sealing even if seals are new.

Diagnostic Steps

Visual Inspection of Door Seals

Inspect door weatherstripping for cracks, separation, or deformation.
Paper Test for Gaps

Place a strip of paper between the door and frame, close door, then try to pull it out; easy removal indicates a gap.
Check Door Alignment

Observe gap uniformity around door edges; uneven spacing can signal hinge or latch issues.
Adjust or Replace Seals

Replace worn seals or adjust hinges to ensure a flush seal.
