I noticed a hesitation when I Pressed the gas pedal, I also noticed the smell of Gasoline when I parked it in my Garage. I had my Certified mechanic look at it and he told me there was a recall on the Fuel sending unit, creating a transfer case failure, apparently the flange breaks and leaks gas. I googled it and it confirms it. I called the local dealer and they have not called me back?

**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.

Dear NHTSA, I am writing to express a serious safety concern regarding the dashboard of my 2016 Porsche Cayenne S. The leather on the dash has begun to shrink and is no longer fitted properly. This misalignment is causing me significant worry about the potential impact on airbag deployment in the event of an accident. Given the crucial role that the dashboard and its covering play in the proper functioning of the airbag system, this issue could compromise the airbags' deployment or effectiveness. This is not only a major safety concern but also poses a risk of the airbags failing to protect occupants as intended, potentially leading to severe consequences during a collision. I am aware that this problem is not unique to my vehicle, as several other owners of the same model have reported similar issues. The potential impact on safety is alarming, and I believe this requires immediate attention. I kindly request that you investigate this issue urgently and advise on the appropriate resolution to ensure the safety of the vehicle’s airbag system. Prompt action is essential to address this potential risk.

While driving vehicle, noticed some slippage/clunking when turning. Took vehicle to Porsche dealer, they said transfer case needed to be replaced. Car has 12,600 original miles on it. Dealer said there was an extended warranty on the transfer case that had expired. In researching, it became obvious that there is a Porsche design problem that affected several model years for the Cayenne. As a mechanical engineer I am concerned that a transfer case failure at freeway speeds could be dangerous. Separately an auto mechanic shop opined that driving without replacing could be a safety concern. In my opinion there should have been a recall rather than a extended warranty.

At slow speed, under acceleration, the transfer case slips, and makes a thumping noise. Over time, the car has poor acceleration when trying to get up to speed with other cars. The dealer has confirmed that this is a problem with Porsche Cayennes. Thank you.

my car had a problem in the hybrid part, before doing the diagnosis they said 3 different problems, when they gave me the diagnosis they said they didn't know what it was but that to begin with “it could be “ the components $13,000 to fix. but my car is under the 8 years or 100,000mls hybrid system warranty, so i contacted porshe headquarters and they said the car was out of warranty. so i called porche in Fremont (where they have mentioned the warranty on their website) and 3 people confirmed that the car is under warranty by VIN n. I called headquarters again and they said they needed this guarantee in writing. So when I called Fremont again 3 weeks later they said the car is not under warranty, meaning they changed the whole conversation within 3 weeks. I already confirmed it on CARFAX and I am under warranty but I never received any responses to emails or phone calls they are ignoring me because they don't want to assume the warranty. Fremont confirmed that I had 6 months or 19,000 miles until the warranty expired, and strangely 3 weeks later that warranty no longer appears in their system. in my opinion they don't know what the car has and they are trying to escape the warranty because there are few months left to finish, that's why they don't give me answers, I haven't tried all possible options and I can't find help to solve this problem, I'm stuck at home dor the last 3 months with 2 children without car. because my only car is at the porsche parked waiting for someone to take over the car's warranty. mentioned that the car had no accident, it was just parked in the garage and one morning it didn't start and had to be towed. Terrible costumer service

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. The manufacturer was notified of the failure and referred the contact to the dealer for a diagnostic test. The dealer gave the contact an estimate without a diagnostic test. The manufacturer was called and informed that they would provide a nominal portion of the repair cost. The vehicle was not repaired. The failure mileage was approximately 65,000. The contact stated that they took their vehicle to a couple dealerships and mechanics before the issue was diagnosed as a design flaw. Therefore, simply changing the headlights out would not fix the problem.
