What 12 owners told NHTSA about the 2017 Porsche Cayenne S E-hybrid

Broken and loosened timing chain cover bolts resulting in leaking oil onto drive components, belts and tires/brakes. This recall was done for the Macan and not the Cayenne. Ours was covered under factory extended warranty. That said, this is criminal. Porsche needs to be investigated, they refuse to recall their vehicles and we all know there are some manufaturing issues that are 100% the factory's fault. If the NTSB refuses to hold their feet to the fire this type of engineering will continue.
