What's wrong?
The windshield on a 2017 Porsche 911 or 718 Boxster is more than a piece of glass. It is bonded to the windshield frame with adhesive, which helps keep the windshield in place and supports the vehicle's compliance with the windshield mounting standard during a crash.
On the affected vehicles, the adhesive used during manufacturing had the wrong composition. That weakens the bond between the glass and the frame. Porsche traced the issue to deviations in the bonding process and found that convertible body styles were affected because of the different stress on the windshield frame.
If the bond does not hold in a crash, the windshield can detach instead of staying seated in the frame. There is no warning sign before failure. The problem is hidden in the adhesive layer, so an owner is not expected to see cracks, leaks, or a loose windshield during normal use.

What should I do?
- Check your VIN to confirm your 2017 Porsche 911 or 718 Boxster is included in this recall.
- Contact a franchised Porsche dealer to schedule the free windshield rebonding that secures the windshield so it stays attached in a crash.
- Bring the recall notice if Porsche mailed one. If not, reference recall number 17V135 when you call.
- Avoid delaying the repair; the windshield bond is part of the vehicle's crash protection.
What happens at the repair
At the dealer, a Porsche technician rebonds the windshield so it is secured to the vehicle as required. The recall repair is available now, and parts and labor are free. Porsche did not create a separate reimbursement program because the affected vehicles were still under warranty when the recall was issued. Ask the service desk how warranty coverage applies if you have prior windshield repair paperwork.
