I bet you haven't been there in a while. It's a lot worse now that the company is hurting for money.
Wrong! Wrong in two ways, in fact.
The service centers are definitely getting better. Communications are actually getting better. They were, unfortunately, god-awful terrible from day one and were getting worse until mid-2018, so they're starting at a very very low standard. It's going to take a while to dig out of that hole.
One reason it's a lot better is that the company has, for the first time ever, got plenty of money. They were being penny-wise and pound-foolish before. Now they're fixing some of that.
The parts delays appear to have largely been eliminated, so that's essentially fixed. (Recently.) The geographic distribution of service centers is being fixed, which is something I've been hammering on for six years. The communications... well, they still need a LOT of work, but the horror story rate is definitely dropping and I haven't heard anything like some of the worst stuff I dealt with in the past.
As sales increase word of mouth will be a much bigger factor in getting new customers than the free advertising Tesla has gotten in the past. News is mostly going to be negative. They need to bank on positive word of mouth going forward and they know it. Not just because other sources will be negative, but because many, many people won't touch a new company selling a totally new product until they talk to owners who are happy with their cars.
Actually, the biggest concern I have currently is if the company will still be solvent in a couple of years. They need a few more billion to pull off both the Shanghai factory and the model Y introduction.
The company will be solvent in a couple of years. You shouldn't worry about it. The Shanghai factory and the Model Y and the Semi are funded at this point. The concern you SHOULD have about Tesla's finances is, will Tesla actually be able to manufacture and deliver enough cars? They've lurched from one production bottleneck to another -- from battery packs to paint shop to general assembly to stamping to paint shop to general assembly to trucking logistics to battery cells. What will be next, raw cobalt supplies? Tires? If they keep having serial production problems, they will remain solvent, but they may not be doing very well.

As a *customer*, your concern should be that if anything goes wrong, you will spend frustrating hours on the phone trying to get to the right person to actually deal with the problem. It's not quite as bad as dealing with American medical billing (I've never encountered anything worse than that), but it is really really bad. I've found once you manage to talk to the actual service tech who is going to work on your car, you're good. But that can take WEEKS.
