This is a serious shot across Tesla's bow and will probably have a negative effect on company valuation and stock price. Essentially, it's FUD that rings true, even among Tesla loyalists.
It seems to me the root of the problem is this: Tesla is, culturally, a Silicon Valley company. Some of that's a plus. Iterative, over-the-air fixes are really great, whether it's a frozen laptop or an unresponsive Model 3. But the attitude of "ship now, fix later" was always going to bite Tesla, and it looks (from these videos from ardent Tesla fans) that it has.
So if you are OK with how your hardware and software problems are dealt with today by "traditional" hardware/software companies, you're likely OK with how Tesla deals with missed appointments, blown deadlines, organizational confusion and mysteriously unresolved "issues". If, on the other hand, you're like virtually everyone else on the planet and hate calling technical support to solve a hardware/software problem, you might well think twice about buying a Tesla vehicle.
As Tesla's founder said a long time ago, Software's easy. Cars are hard.
He was right.
