However, powering did not work +anymore.There was a red warning message and no way to start the car +anymore. Or to open the windows, to lock the door, almost 100% of the +electric system of the car shutdown over night. + +A bit unfortunate, when you have to get to a business appointment. + +After a lengthy discussions and multiple trial and error approaches +from the Italian motor support that is provided by Porsche, one +assistance was able to get the car working again by jump starting +it. + +That's somewhat puzzling, as it's an EV and additionally tricky, +because the internal 12V battery is an Lithium Ion battery and not a +regular lead battery. + +That said, with a lot of fear I returned to the +The [Porsche Center +OZS](https://dealer.porsche.com/ch/obererzuerichsee/de-CH) +in Switzerland, fully exhausted and sweated through, never knowing +whether the car will just break down. + +Around the same time the two front windows started to squeak every +time you'd use them. + +The Porsche Center OZS replaced the main battery of the car, +replaced the guides for the windows and after about 4 weeks on +**2024-06-27** I was able to pickup the car again. At this stage the +amount of hours put into repairing exceeded 50 hours by far. + +## Review + +Again, like in many of the other experiences, there are a variety of +different aspects to this problem. Let me start with the most +inconvenient one: + +### Italian motor support & Porsche assistance + +With every Porsche, like with most modern cars, you get some kind of +"mobility warranty". Which basically means, you have a direct vendor +contact and they ensure you can "always" drive. So the coordinate the +pickup of your car if it breaks down, provide a replacement car and so +forth. + +There will be an article about the assistance on its own in the near +future. + +That said, the cooperation between "Swiss Porsche Assistance" and +Italian motor support is a catastrophe. When you call the Porsche +Assistance, you will get one information ("they are coming soon"), +when you get a call from Italian motor support, they tell you it's a +holiday and they come in 1 or 2 days. + +So one is not only left in a limbo between not knowing, but also +having contradicting information into late of the night. + +### Contradicting information on handling power failure + +While being in this situation, I talked to various parties, including: + +* First Italian motor support guy +* Second Italian motor support guy +* Third Italian motor support guy +* Italian motor support hotline +* Porsche Assistance +* Porsche Center OZS + +Besides contradicting information about the when, also the how to +approach the problem was contradicting: + +* Italian motor support hotline: we will send someone to fix +* First Italian motor support guy said: cannot fix, it's an EV. It's + also too big and too heavy to be loaded on his tow truck. He left + within 5 minutes of arrival. +* Porsche Center OZS: Do not jump start with power booster.

Leaves afterwards, also saying there needs + to be a bigger towing car + +### Leaving on my own - full of uncertainty + +After that bad experience and after extending the stay in the hotel +for one more night, I decided to try my luck and drive as much back +into Switzerland as possible, to at least be back with the Swiss +support system. When returning there was a big traffic jam just before +crossing from the South to the North of the alps, so I decided to go +over the mountain pass instead of the tunnel. + +For a few hours I was in the middle of the mountains, not knowing +whether the car will arrive or fail any minute. + +In the end I was lucky and reached the Porsche Center OZS extremely +exhausted in the evening. + +### The failure itself - sign of poor quality and no reliability + +If that was the first failure, I think I'd have been a bit mad. But +being one in a long streak of failures, I can only reason that the +build quality of the Porsche Taycan is poor.
