I purchased a porsche panamera with 130k miles on it and had the oil changed and transmission serviced at German Car Specialist Auto Shop in Bellevue. 5k miles later my transmission went out on my way to work. The transmission had been service before at 69k miles. That's what it stated on the carfax report. I had the car towed to German Car Specialist and they looked at it and told me it was nothing they could do and to take it to the dealership. I whole heartedly believe German Car Specialist Auto ruined my transmission. The guy that runs the shop didn't even know how to show me how to check my oil when I asked him. He had to go get another person at the shop to show me how to check my oil. I had the car towed to the dealership and they said it was the distance sensor and that they can fix it for 5k but it may only last a year or two at best. I then had the car then towed to Chris's German Auto Service. I was told by Alex, one of the service advisors that they could get me a transmission with a warranty from their parts supplier or they could rebuild the transmission. I decided to go with them getting me a transmission from their supplier. 3 to 4 months passed by and they never got a transmission for my porsche. Alex the service advisor pulled up some transmissions on ebay and stated to get one from there, but I was a little skeptical. I felt pressured into getting a transmission from ebay, so I found one and emailed him the links to the transmission, and asked him should I purchase this particular one and he said yeah it looks good. When the transmission arrived, I asked Alex again to inspect the transmission and he stated the transmission looks great and it looks like it was rebuilt with new parts. They installed the transmission and didn't even know how to calibrate it. They didn't even have the tools or device to calibrate the transmission. They sent it to Porsche Bellevue without even telling me to get it calibrate and charged me over 2k for it. The transmission did not work after Porsche Bellevue calibrate it and Chris's German Auto told me the transmission needed a new clutch. They said I owed them over 8k for a still broken transmission that doesn't even work. I felt like I was given bad advice by Chris's German Auto and that they tried to take advantage of the situation, instead of trying to make it right and admitting to their mistakes.
