AIR BAGSJuly 7, 2025
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.
AIR BAGS,UNKNOWN OR OTHERDecember 14, 2024
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.
ENGINEJune 3, 2024
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.
ENGINEApril 20, 2024
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.
EXTERIOR LIGHTINGDecember 17, 2023
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.
POWER TRAINApril 20, 2023
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.
ELECTRICAL SYSTEM,UNKNOWN OR OTHERFebruary 23, 2023
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.
EXTERIOR LIGHTINGFebruary 10, 2022
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
