What's wrong?
The windshield and rear window on the 2020-2024 Porsche 911 are bonded to the body with adhesive around the glass edge. That bond holds the glass in place, helps seal out water, and keeps the window from shifting when the body flexes or the car is moving.
On affected 911 vehicles, the supplier did not complete the cleaning process correctly after a potassium salt bath, a chemical treatment used before bonding. Salt bath residue stayed in the primer area, the surface where adhesive is supposed to grip the glass. That residue interferes with the bond between the glass and the body. If the adhesive does not hold, the front windshield or rear window can detach.
What you notice first can be wind noise, water entering around the glass, or both. Porsche also found cloudy surfaces and other optical defects during its review, but the owner-facing warning signs are noise and water intrusion.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific car is included.
What's the safety risk?
An unsecured windshield can leave the front air bags without intended windshield support during deployment, increasing the risk of injury in a crash. Wind noise or water entering the cabin are warning signs to treat seriously. Schedule the inspection soon and drive cautiously until the dealer checks it. Repair is free at any franchised Porsche dealer.
What should I do?
- Check your VIN to confirm your 2020-2024 Porsche 911 is included in this recall.
- Contact a franchised Porsche dealer to schedule the free windshield and rear-window inspection and replacement if needed.
- Bring the owner letter if you have it. If not, reference recall number 24V155 and Porsche recall ARA3 when you call.
- Drive with care until the inspection is complete, and avoid delaying the repair; an unsecured windshield or rear window can detach.
What happens at the repair
At the dealer, a Porsche technician inspects the front windshield and rear window to confirm they are secured correctly. If either glass panel fails inspection, the dealer replaces it. The inspection, replacement parts, and labor are free under the recall. Porsche's standard reimbursement plan covers documented expenses for eligible windshield or rear window repairs paid before the owner letter. Bring repair invoices, proof of payment, or related paperwork to the service desk.
