**Subject**: Urgent Safety Concern: Headlight Condensation and Water Damage in 2015-2018 Porsche Cayenne 958.2 Dear NHTSA, 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 NHTSA 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 water had leaked inside the front driver's side and passenger's side headlamps. The contact stated that the failure caused the headlights to become foggy and significantly dim, reducing the visibility of the roadway. The contact stated that he had received notification of NHTSA Campaign Number: 22V656000 (Exterior Lighting) and the vehicle was taken to the dealer, where the recall repair was performed. The contact stated that the dealer sealed the headlamps while there was water inside. The dealer declined to perform additional repairs. The manufacturer was notified of the failure and referred the contact to the dealer for assistance. The vehicle was not repaired. The failure mileage was approximately 86,000.
the driver receives a warning light in the instrument panel left tail light is defective, and then right tail light defective. Some times tail light works and does not when car is in cold weather Was told that both tail lights were defective and would have to be replaced at a cost of $3400. Found an after sale Porsche publication saying that it affected 2015-2018 Porsche Cayenne. Dealer told me that it is no longer covered since my warranty is not in effect anymore. However this is a safety issue not a warranty issue. Have paperwork stating that Porsche knows the tail lights are defective. Since I live in Florida they have been working fine. But as soon as the car is in colder climates this starts to happen
