A good friend ordered a new Model S in 2015. It arrived with a "squeak" that turned out to be due to missing welds in structural components of the chassis. They wanted him to sign an NDA to get a replacement vehicle (which he refused to do, both on principle, and because he'd talked to friends about it already). So he was forced to keep his vehicle, which was then repaired under warranty for what they initially said was not a warrantable defect. To quote him "They took a huge proponent and turned them into someone who will never, ever, recommend them"
And this is how they treated their early adopters that were paying $100K in 2015 for their higher end cars.
