I play a nice person on twitter.
Like any industry, QC is not always 100%. This shoddy workmanship is not the norm for Tesla service centers.
Our Scottsdale AZ team is pretty solid and conscientious. Good management at that store is the catalyst.
I did however find Arizona based Gruber Power Services did my PEM maintenance flawlessly, and at a far better rate.
I understand they even repair PEMS unlike Tesla's only option - replacement.
Plenty of Roadster owners on this forum have reported Tesla repairing their PEMs.
