Just got news.
The computer handling the battery got bricked doing the software update.
Coming from Germany in February 🤦🏼♂️.
And they will be doing also the passenger seat belt, the trunk cover, and the rear latch rattle.
I have a Cayenne S loaner since December 5th.
My car has been at the dealer since December 5th.
Seems the update bricked one or many of the car's computer.
They had to escalate the matter to Porsche Canada to get permission for certain interventions. Nothing solved yet.
