Driving through a parking lot, less than five miles an hour, and suddenly heard a horrible knocking sound. Stopped and looked under the car. Nothing. Drove it very slowly to mechanic less than a mile away. Front drive shaft had collapsed and fallen down, according to the mechanic.

This is not accident related, but what appears to be a systemic issue related to Cayenne and Macan leather dashboards. The issue is related to delamination of the leather dash cover that can impede the safe deployment of the passenger airbag. Many cars are affected and the repair can be a significant expense to owners (~$10K) for vehicles less than 8 years old. There should be a recall to address ...
The Porsche Cayenne that equipped with leather dashboard are peeling off over the time. If the vehicle in an accident, the airbag on the passenger side dashboard may not deploy correctly. I am finding many cayenne owners are having this issue. I really hope NTSB can issue a recall.
While the vehicle was charging, the protective sheath near the power outlet of the charging cable had possible electrical or fire damage. No warning lights were illuminated. Upon turning off the power and unplugging the outlet, it was determined that the plastic near the plug melted and caused the power to short. I have been unsuccessful getting the manufacturer to resolve the issue. A recall unde...

I took it to someone to look at and they said this should not be happening, that it is a manufacturer defect. I googled my car / year and there is a recall for headlight issues but for some reason my VIN is not included. It should be. How do I go about having Porsche ...
The day we took our Porsche home, we noticed a lot of heat generation in the car- but we thought it will be fine going further, given the attention to detail of Porsche's Automobile Engineering. The following days were not any better for my daughter- she missed a major accident because of the unexpected burnt smell and loud warnings of an overheat of the engine by Porsche in the middle of a highw...

Component: Air Bags:Frontal:Driver Side:Inflator Module
Opened 2021-09-17
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 20...
