I suspect the Model 3 delay pushes the smaller battery option to early 2018, which, in the grand scheme of things is a non-issue IMO.
The other items in the Electrek report (seats, headlights, etc) seem mostly benign and solvable.
I'm interested to know what the issue was with the battery pack. We know Elon was just at the Gigafactory the other day, which makes it hard to imagine his presence isn't related. I guess we don't have too much information for informed speculation, but my questions would be -- Was it a production issue? Was it an assembly issue? Was it a component issue?
And, is it solved?
