I have a 2015 Macan S with the same leaking timing chain cover issue. Unfortunately, i brought the car twice (under warranty) for repair and it was dismissed as "normal" by Rusnak Porsche Thousand Oaks. The third time I brought it (out of warranty) they said it needed it needed repair. The cause, 2 broken aluminum bolts on the timing chain cover. Sounds familiar.. I contacted the service director at Rusnak to discuss, but he was zero help and proceeded to tell me this was a maintenance repair. When I inquired why it was the 2 broken bolts weren't found while the car was under warranty he proceeded to suggest they weren't broken at the time. Sounded a lot like deflection to me.
I filed a case with Porsche North America. After two weeks of "investigation" this was the response..
"Thank you for reaching out to PCNA in regard to the goodwill request for the coverage of the timing cover bolts. While processing the research in your case I discovered that there are no current warranties that exist to cover the replacement of the timing cover bolts. This repair would be part of the maintenance of the vehicle; which is part of the ownership of the vehicle. Any goodwill that could be offered would be at the discretion of the dealership. I appreciate your patience during the consideration of goodwill in your case.
