Porsche dashboard leather shrunk and is bubbling on the entire top where the Airbag sits. I was told that if the vehicle was in an accident the airbag might not deploy correctly. The Porsche dealer looked at it and recommended replacing the entire dashboard! This is a very common issue with Porsche, and a safety concern which seems due to the fact that Porsche did not use the correct adhesive on all most of cars build in the last 10 years. The dashboard is not withstanding normal sun light and this causes a safety issue.

My 2020 Porsche Cayenne has experienced leather dashboard delamination, with the leather separating, shrinking, and lifting from the dashboard substrate on both the driver and passenger sides. The delamination extends across the upper dashboard, including areas adjacent to the passenger airbag deployment zone. I am concerned that loose or detached dashboard material could interfere with, delay, or alter the proper deployment of the passenger airbag during a collision, increasing the risk of injury. The continued deterioration also raises concerns about the integrity of the dashboard structure over time. Porsche inspected the vehicle and determined that the repair requires replacement of the…

Seat belt and airbag indication lights and sound alarms remain on and notifying on the dashboard regardless of buckling. It will intermittently stop and start as the car is in motion. In the beginning, notification was present then resolved day-to-day. More recently, the alarm is present every drive. Driver was unsure whether or not the notifications were valid or not as the pattern of notification had little consistency. Dealership service later admitted that it was a faulty seat belt buckle and that part had failed internally, but refused to remedy it unless paid for. Car is essentially inoperable and unsafe until faulty buckle is replaced, as a faulty seat belt buckle can be fatal, with…
