Solution

1. Preparation

Tools Required: Basic hand tools, trim removal tools, stethoscope
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect Seals

Sub-steps:
1. Close all windows and doors.
2. Visually inspect the door seals for cracks, tears, or deformation.
3. Run your fingers along the seals to feel for any irregularities.
4. Replace any damaged seals with OEM parts if necessary.

3. Adjust Body Panels

Sub-steps:
1. Check alignment of the front fenders, hood, and rear trunk.
2. Loosen the bolts securing misaligned panels, adjust them to fit snugly, and retighten to manufacturer specifications (typically 15-20 Nm).
3. Ensure all clips and fasteners are properly installed and secure.

4. Underbody Inspection

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Inspect the underbody for loose panels, particularly the front and rear air deflectors.
3. Tighten any loose screws or bolts and replace any missing fasteners.

5. Test Drive

Sub-steps:
1. Conduct a test drive at highway speeds to check if the noise persists.
2. Monitor changes in noise with different window positions to further isolate the source.
