**Subject**: Urgent Safety Concern: Headlight Condensation and Water Damage in 2015-2018 Porsche Cayenne 958.2 I am writing to report a serious safety issue with the LED matrix headlights on my 2016 Porsche Cayenne GTS (958.2). The problem involves severe condensation buildup within the headlight assembly, leading to water damage and electrical failures. This defect has caused my headlights to fail, particularly during nighttime driving in heavy rain, which significantly reduced visibility. This failure could have resulted in a major accident, putting my life and the lives of others at risk. The vehicle is available for inspection upon request. The issue first became noticeable after a rainstorm, where condensation started to build up inside the headlights. Despite multiple visits to my local Porsche dealership, where they confirmed the problem and attempted repairs, the issue continues to persist. I also notified Porsche corporate directly, but neither the dealership nor Porsche offered any assistance or permanent resolution. Both have failed to take responsibility for what I believe is a widespread defect, as I have found numerous similar reports from other owners. No warning lights or messages were displayed prior to the headlight failure, which made the issue even more dangerous. Without any prior indication, I was left driving without functioning headlights at night, in poor weather conditions. Given the potential for catastrophic consequences, I strongly urge the federal safety agency to investigate this issue. A recall or other corrective action is necessary to prevent further risks to drivers. Thank you for your attention to this matter.

The contact owns a 2016 Porsche Cayenne. The contact stated that moisture was entering the headlights on both sides of the vehicle. Over time, the condensation in the passenger’s side headlight was burned out with a message on the instrument panel.
