Example complaints

Transmission and drivetrain: “While shifting from 5th to 6th gear, I felt something (presumably the shift cable) snap. The car was locked in gear, and I was unable to shift to another gear. In looking online I found complaints by several other Porsche owners that shift cables on their cars had broken.”

NHTSA complaint #10705204, filed 2015-04, 34,235 miles

Engine: “The vacuum pump (Porsche part number 9A1-110-090-02) cover retaining screws vibrated out causing the cover to damage the fuel lines and causing an engine oil leak. The fuel and oil were ignited by the exhaust or stray spark cause by the vacuum covers rotation and hitting other metal objects. This vacuum pump provides vacuum to the brake booster and during the event drastically reduces the ability of the car to stop. …”
