Model S Owner and Frustrated Tesla Fan
A vast majority of these issues are "early production run" issues.
I should mention that I had the "loose chargeport" issue; the chargeport didn't seat the cables properly, and probably as a result destroyed three cables. Replacing it with a new chargeport fixed the problem. This is a case where the part Tesla was initially using didn't meet tolerances; new parts, such as used in new cars, are from a different supplier IIRC, and certainly are meeting tighter tolerances.
The 12V battery issues are the same sort of thing -- Tesla switched their specs and supplier for the 12V battery, so new cars won't have the old problems.
The alignment issues are the same sort of thing -- Tesla's alignment machines had the wrong specs programmed into them, and thsi has now been fixed.
You get the idea. If you buy a new car now you are unlikely to face any of these issues. If you buy a used Signature, you'll probably face every last one of them, unless the previous owner had them fixed (so ask for the repair records).
(Incidentally, this is why I would not buy a Signature Series from Tesla unless I was in a raging hurry to get my car. Paying extra for an early production run model means you're paying extra for an inferior model.)
