2021 Porsche Panamera 4 E hybrid executive

Hi! This is Bo with Car Genius at RepairPal! This is an interesting symptom and it possibly indicates a potential dependency on the hybrid system's charge level to start the engine. This could be a feature designed to encourage hybrid usage or a technical issue related to the vehicle's hybrid powertrain management system. Since it's a 2021 model, it's likely under warranty, so contacting your Porsche dealership for assistance and possibly a software update or system check would be the best course of action to ensure proper functionality. If you have any other questions feel free to call us at 877-913-1554! We'll be happy to find you a certified shop in your area!
