Over approximately the past month, the leather covering on the dashboard of my 2021 Porsche Cayenne has rapidly begun lifting, buckling, and separating across a substantial portion of the dashboard. The deformation has become increasingly pronounced in a short period of time despite normal use and careful maintenance of the vehicle. I am concerned that this may present a safety issue because the passenger airbag deploys through the dashboard area. The dashboard material is visibly distorted and separating, and I am concerned that this deformation could potentially interfere with the intended deployment path or performance of the passenger airbag in a collision. This does not appear to be normal cosmetic wear. The affected area is not routinely touched or subjected to ordinary wear, and the condition developed quickly on a relatively recent vehicle. I have also found reports from other owners of similar Porsche Cayenne model years describing comparable dashboard leather lifting, bubbling, warping, or delamination. Because of the location of the defect and the potential relationship to the passenger-airbag deployment area, I am requesting that NHTSA review this condition as a possible safety-related defect. I have contacted Porsche Cars North America regarding the issue and am seeking inspection and repair through an authorized Porsche dealer.

Battery completely discharged and the safety switch in the battery malfunctions and battery can not be charged again. There are many complaints seen online about the battery problems Porsche has. This strands the car and me the driver. The dealer and independent mechanics said the same. There were no warning lamps or messages prior to the failure.

While driving at highway speed, my 2022 Porsche Cayenne S experienced an air suspension / air spring strut failure requiring a dealer repair costing approximately $4,000. Porsche has a related service campaign, WND6 / No. 74-22, for replacement of the front-right air-spring strut on certain 2021-2022 Cayenne vehicles, but stated that my VIN wasn't included in this service campaign. I am reporting this because my vehicle suffered the same failure mode described in the campaign, creating handling and suspension safety concerns. This failure manifested itself while drive increasing the risk of a serious accident. At the time of the incident, the car was 4 years 5 months old and had less than 10,000 miles. The issue first manifested itself with a warning: Chassis System Fault. It then followed up a few miles later with a critical fault: Chassis System Failed.

On the afternoon of June 24, 2026, at approximately 5:40 PM, I experienced a severe, sudden braking system failure that directly caused a rear-end collision. I was driving my 2023 Porsche Cayenne E-Hybrid on the highway, traveling to a concert scheduled for 7:00 PM. The highway traffic was heavy and slow-moving (stop-and-go). I was cruising at a moderate speed of approximately 40 to 50 mph. The vehicle ahead of me applied its brakes and came to a gradual, normal stop. I was maintaining a very safe following distance of approximately 30 meters (around 100 feet) behind that vehicle. As I perceived the traffic stopping, I immediately attempted to apply my brakes. However, the brake pedal instantly became extremely hard, felt completely locked up like a stone, and was impossible to press down. Despite having ample distance to stop and applying all my body weight and force onto the brake pedal, there was zero brake assistance from the vehicle, and the brakes failed to engage. The onboard Forward Collision Warning and Automatic Emergency Braking also failed to prevent the accident. As a result, I was completely unable to reduce the speed of the car, and my vehicle rolled forward and collided into the rear of the car in front of me. This was entirely a mechanical/electronic safety system failure. The vehicle is currently available for inspection, and I am requesting a full diagnostic download of the EDR and DME data before any repairs are performed.
The emergency braking system light and the adaptive control cruise control is not working in the warning. Lights are on from Dave that I’ve got it from day one January 2026.
