Complaints are self-reported and skew toward problems people find alarming, so treat this as where to look, not a defect rate.
the piece of leather trim sit on top of dash panel below the windshield that cover the airbag shrink and peel off the main dash. The passenger air bag might not deploy properly in the event of frontal collisions because of a loose piece of leather cover it.
Passenger side dash board leather cover has pulled away from dash - thus creating a safety issue with the airbag. Porsche has examined the damage and recommended a repair but will not cover the cost - but did advise that in the event of a accident - they do see a potential problem with the passenger side air bag deploying safely (or not at all). There should be a recall on this by Porsche as it's a safetly issue.
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.
Oil leaks from timing chain cover due to defective bolt material, bolts loosen and break. This is a widespread known issue with Cayennes and Macans.
The two headlights have appeared to have condensation due to sealing problem of the headlight. When the light bulbs and beam heat up the air with moisture, it will leave water inside of the headlight cover. This will increase the safety risks when we were driving on the road. There is no warning message for that. The problem should not be normal and this should really be manufacturer’s problem to fix.
The contact owns a 2017 Porsche Cayenne. The contact stated while driving approximately 30 MPH, the vehicle stalled in the middle of a road. The contact stated no warning light was illuminated; however, the contact had been hearing an abnormal rattle and knocking sound from under the floorboard. The contact had the vehicle towed to a local dealer, where it was diagnosed and determined that the bolts from the transfer case had loosened, and the case had separated from the drive shaft. The vehicle had been repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 42,000.
Porsche and VW has a drainage issues with certain model vehicles. The drainage plug is set in the trunk near the battery, main system cpu and amplifier. Water gets drain into the lower compartment of the trunk and causes electrical issues with the vehicle. It's been a design flaw from porsche since before the Cayenne was created. To repair the damage it cost upwards of $3,000 per damage battery, electrical components, amplifier are all billed separate. Porsche warranty refuses to honor the design flaws in correct the issues. Owners are not made aware of the issue until it becomes an issue then porsche wants no part to do with it. The drainage location can cause an electrical fire and engine malfunction while driving.
The headlights aren’t sealed correctly so water has leaked in and caused them to malfunction. Porsche is making me get them repaired at a cost of $4100

ACC/ PAS UNAVAILABLE WARNING: APPROXIMATELY EIGHT MONTHS AGO WHILE DRIVING ON A CITY STREET IN SARASOTA, FL THE PAS SYSTEM WAS ACTIVATED AND ABRUPTLY STOPPED MY VEHICLE WITHOUT REASON. ON TWO SEPARATE OCCASIONS THE "ACC/PAS IS UNAVAILABLE" WARNING HAS APPEARED ON MY INSTRUMENT PANEL. ON THE FIRST OCCASION, A VEHICLE TO MY LEFT WAS ATTEMPTING TO MERGE INTO MY LANE OF TRAFFIC WHILE WE WERE APPROACHING AN INTERSECTION ON A CITY STREET. I ATTEMPTED TO HONK MY HORN (WHICH FAILED MAKING AN AUDIBLE SOUND) AND SWERVED TO PREVENT THIS IMPENDING COLLISION. THE DRIVER OF THE VEHICLE IN FRONT OF ME ALSO WITNESSED WHAT WAS OCCURRING AND SLAMMED ON THEIR BREAKS. MY PAS SYSTEM FAILED TO ALERT AND APPLY PRESSURE AND/OR STOP THE BREAKS AS THIS SAFETY FEATURE IS DESIGNED. DESPITE MY EFFORTS TO BREAK QUICKLY THE VEHICLE IN FRONT OF ME AND I COLLIDED. THE FIRST DRIVER THAT MERGED INTO MY LANE FLED THE SCENE. THERE WAS NO DAMAGE TO THE VEHICLE IN FRONT OF ME AND THE PORSCHE HAD MODERATE FRONT END DAMAGE. A POLICE REPORT WAS FILED. THE VEHICLE WAS TAKEN TO OUR INSURANCE COMPANY'S AUTO REPAIR EXPRESS PROGRAM AT A COLLISION CENTER OF THEIR CHOICE. IT WAS THEN SENT TO OUR LOCAL PORSCHE SERVICE DEPARTMENT FOR INSPECTION AND REINSTALLATION AND CALIBRATION OF THE PAS CAMERAS AND OPERATIONS. ON THE SECOND OCCASION APPROXIMATELY 10 DAYS AFTER HAVING THE VEHICLE BACK FROM THE BODY SHOP AND INSPECTIONS, I WAS SITTING AT RED TRAFFIC LIGHT ON A CITY STREET. THE LIGHT CHANGED GREEN, CARS BEHIND ME STARTED HONKING. THE CAR IN FRONT OF ME BEGAN TO PROCEED THROUGH THE LIGHT BEFORE BREAKING ABRUPTLY. AGAIN THE "ACC/PAS IS UNAVAILABLE" WARNING APPEARED ON THE INSTRUMENT PANEL PRIOR TO THIS AND MY BREAKS DID NOT RESPOND TO MY APPLIED PRESSURE. I HAD NOT YET ACCELERATED.
