This page covers 3 recalls and 13 owner complaints for the 2015 Porsche Cayenne.
For the 2015 Cayenne, the complaint set is small but spreads across a few systems. Powertrain and exterior lighting each draw the most reports. On the powertrain side, owners describe throttle response problems, specifically, no response until the pedal is fully depressed, followed by sudden, uncontrolled acceleration. Exterior lighting complaints center on headlight failures, with one owner reporting a blown fuse that killed the headlights while driving at night, and moisture found inside the headlight lens afterward; a separate pattern involves false warning messages indicating rear lights are malfunctioning when the lights appear to be working normally. Electrical complaints include a reported instance of the vehicle being remotely disabled through a connected-services system the owner says they did not subscribe to. A single report also mentions an airbag warning light tied to a passenger seat occupant-detection fault.

Total Complaints
By System
The 2015 Porsche Cayenne has 3 recalls, the most serious involving a brake pedal that can physically dislodge while driving, leaving the driver unable to apply the brakes.
A small retaining clip that holds the brake pedal's pivot pin in place may be missing, allowing the pin to shift and the pedal to come free from its mount entirely. On the suspension side, certain Cayenne Diesel and Cayenne S models built within a narrow two-day window in late November 2014 may have received incorrect wheel alignment at the factory, which can cause the vehicle to handle unpredictably and reduce the driver's ability to steer through corners or emergency maneuvers. There is also a headlight adjustment concern shared across a wide range of Porsche models: the headlights on some vehicles may point too low to light the road ahead properly, or too high, creating glare for oncoming drivers.
