It's almost always the seal
A water leak or a wind whistle after a windshield replacement points to the urethane seal — either it wasn't applied evenly, the glass wasn't set perfectly, or it wasn't given proper cure time before the car was driven. A correctly installed windshield is watertight and quiet at highway speed.
How to spot the problem
- Wind whistle or roar that appears at speed and grows with it
- Water intrusion — damp headliner, A-pillar, or footwells after rain or a car wash
- Fogging inside the glass from trapped moisture
Don't ignore it — a leak can lead to rust, mold, and electrical issues over time.

Frequently Asked Questions
Is a whistling noise after a windshield replacement normal?
No — a properly sealed and set windshield is quiet at speed. A whistle usually means a molding or seal issue that should be corrected under the workmanship warranty.
Should I pay to fix a leak from a recent replacement?
No — a leak from a recent install is a workmanship defect and should be repaired free under a lifetime warranty. Contact the installer right away.
