I'm not on Social Media (other than here) so I can't really say anything about that. Other than, don't believe every negative thing you read. People vent on SM about all sorts of things. Some have truth behind what they are saying, while others can be bots that are trying to exert some influence. As others have said, people rarely sign up with web forums so that they can talk about all the great things their car, camera, computer, etc. has or does. If somebody has an issue about something, it's human nature to get up on a soapbox and shout.
Only a single model Tesla owner from July 2018 (Model 3 LR RWD VIN 444XX) here. Pickup experience was good (Fremont, CA). I inspected the car then arranged payment via bank transfer. Nothing about the vehicle was that far out of line. Sure there was some panel alignment inconsistencies but I've had that with other makes before (Mazda, BMW). In and out in about 90 minutes. I had read up on the features of the car and had rented one a few months before so I knew what to expect with the car. Minimal handholding by the sales personnel. Again, this was in July of 2018 when the first Model 3s were just a few months old. I'd think that the delivery experience is much different by now. Certainly the build technique is probably changed. Whether that's good or bad, I have no comment on.
One minor problem that I discovered while driving home with my new car was that the tire pressure system (TPMS) was not working correctly. This was fixed after a couple of months via an over-the-air update/reset. Second issue was that after a few months my car no longer completed software updates. I had scheduled a visit to a local service center but on the evening before they contacted me and said they performed a reformat on the SD card, again over-the-air, which fixed the problem.
I've had mobile service in my driveway a couple of times. Once to perform the HW3.0 update and another time for the upper control arm re-seal. I proactively replaced the 12V battery just before it reached four years old. Did that as I was going on a long trip and didn't want that to be an issue (many reports of the 12V failing around 4 years of age). Had mobile service replace the cabin filters too. Great service if you have access to it. Have visited brick-and-mortar service a few times (Santa Clara, CA), mostly as a walk-up (tire patching one time and when it got another nail, replacing both rear tires). I've also gone in to buy items such as keycards, rear quarter windows, charge port ECU and the charge port door sensor target; no issues. No major mechanical issues with the car in the nearly 5 years I've had it.
I don't know what Tesla service coverage is like in WV. I'm lucky to live near the factory (20 miles away) and have several service centers nearby.
