I dont understand Your question. This is a car made for driving in same climate as every other car. I do not drive my Taycan often. But I drive it when needed. As I did with my 911 before I sold it. Summer and winter. You just need winter tires when its could.
The guy servicing my car at dealer gave me a tumbs-up for those grills. Said they were good for stopping debries from damaging radiators. Nothing about canceling warranty.
There is too often something-going-on when you start the car. Usually listening to spotify. Sometimes car switches to FM instead. Other times it pops up some question about Android Auto. I would almost say this i just the way Taycan sw works
