I had a problem with my dealer returning calls. I contacted Porsche support by email and described the problem with my dealer. Support responded the next day and so did my dealer. The dealer is now corresponding daily. Maybe you should go directly to support and establish a written complaint trail.
No loaner. Just no clock. Spent many hours with Porsche customer service and a number of the problems have been resolved. Mostly by accident and not by design but that’s another story. Still trying to fix a couple of problems but the car is running and performing well.
Dealer had my turbo for a week. Upgrade has been a disaster. Porsche trying to figure out how to solve all the problems associated. Better if they could rollback prior to update.
I am in category 3. I’m very dissatisfied with the lack of response from either Porsche or my dealer. Some of the buzz has worn off and I’m considering all my options. As one investing over $200G I’d expect better service.
