THIS problem has not been resolved... And getting stranded, car catastrophically failing IS scary and Tesla has not addressed it.
I'm quoting Scott here but he's far from the only person who's expressed this idea, specifically that Tesla is not addressing this problem.
First of all this type of comment presumes that this is a single issue. We know that there are multiple failures that can result in the same behavior. 12V battery dying, DC-to-DC converter, HV battery contactors, etc... So the fact that some people are having issues with similar outward behavior does not mean they are having the exact same failures.
Second it presumes that Tesla is doing nothing about any of these failures, which we have signs that this is simply not true. We've seen newer revisions of the HV pack, which based on postings here have had far fewer contactor failures. We've seen Tesla contacting owners wanting to proactively replace contactors in older vehicles (presumably because they had a higher failure rate than Tesla has deemed acceptable). And that's just what we know about when it comes to the contactor failures. I'm sure Tesla has done other things about other component failures.
Third it presumes that the resolution to the failures is that nobody will ever have such a failure again. All parts have a failure rate. It's useful to remember that all of these vehicles are made by human beings (or by machines made by human beings) and despite our marvelous ability to improve human beings are still not perfect. So no matter what Tesla does it's likely there will still be failures in components that can cause such failures. No amount of effort at checking the quality of the components can catch every component that may fail.
It ignores that the likely reason for the situation is the brittle design of the 12V battery holding the HV battery contractors closed is likely a reaction to the
FMVSS No 305 (Federal Motor Vehicle Safety Standard). That requires the HV power be isolated after an accident. Early Roadsters did not have this design but later Roadsters ended up having a similar design, implying to me that this is likely a design change driven by regulation. This design is brittle because you have multiple components that represent a single point of failure in the ability of the car to move itself. Fixing those single points of failure is somewhat in conflict with the safety standard, probably not cost effective, and given the failure rate of the components may not represent a significant reduction in such incidents.
None of this is to say that owners shouldn't be concerned by this. But we should at least recognize that Tesla is not ignoring such issues given the above evidence and have realistic expectations for what resolution means (i.e. resolution does not mean it never happens again).
