Owner report 11636091 · 2025-01-15 (January 15, 2025)
When the weather drops below 0 celsius, the hybrid battery fails with a hybrid battery failure message. The Porsche dealer said this is a known issue and there is no fix. I've been stuck several times in the past 3 years up in the mountains when the temperature drops suddenly and there are no services within 100's of miles to even tow it to get a fix. I just have to wait for the temperature to warm up to start the car. There is currently no bypass to switch to gas only which would solve the issue. If you look at the pic, there is plenty of gas …

Owner report 11703739 · 2025-12-08 (December 8, 2025)
I am reporting a series of safety-related defects involving the electrical, cooling, and fuel systems of my 2021 Porsche Cayenne E-Hybrid. The vehicle was initially brought to the authorized Porsche dealership due to an electrical system error, and the dealer kept the vehicle for an extended period. After approximately five months, the vehicle was returned to me without a clear explanation of the root cause or details of the repair. The very next day after receiving the vehicle, a coolant temperature warning appeared while driving, indicating …

Owner report 11592066 · 2024-06-03 (June 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.
