There are 2 owner-reported engine complaints for the 2017 Porsche Cayennein NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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.
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.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
