Unless you have bad luck and run around with a gap scale, measuring all of the panel joints, you'll most likely, never have a problem with a Tesla. I haven't seen any noticeable issues with Teslas. I just had my first service (other than one where the culprit was my antiquated iPhone) on my 2018 Model 3 after 104,000 miles. They preemptively replaced my 12-volt accessory battery and the mobile charging connector - at no cost to me. This took about 20 minutes and was done by a knowledgeable mobile technician. He arrived at my house in a Model S that had been outfitted with tool boxes as a mobile service vehicle.
Tesla drivers, for the most part, are well supported and having a great time on the road.
I've driven all over the USA and, with almost no exceptions, only see Teslas on the road. Why is this?
Even in the most remote locations, there are Teslas using Supercharger stations. EA stations are always empty. Why?
Don't take my word though. I might just be a Tesla Fanboi of which you've witnessed that I've been accused. Swing by the 3 DC Fast charge sessions in Sudbury and see for yourself.

Check out others around you (find them on plugshare.com).
You might even ask the people you see at them what they think. Watch how long they spend there. They are, most likely people who don't waste time on forums trying to force their opinions on others or attacking them online.
I'm sure you'd benefit by a non-Tesla EV, however, I don't recommend that you rule-out a Tesla just based on the hatred that you see around here. Most Tesla owners don't participate on non-Tesla forums. They're just driving around like with any other car.
I do know one person who ordered a Model Y and found the car they brought him to have fit and paint problems. He rejected that car and they got him a different one. A quick inspection upon delivery is all it takes to see if you have a "friday afternoon build". I also understand that Tesla has learned to do a better job at catching cosmetic quality issues themselves.
The biggest difference between a Tesla and other EVs is that Teslas are on parity with ICE as far as lifetime cost, convenience, and utility. With other EVs, you'll need an ICE for convenient long trips, especially winter ones. Unlike with ICE, where all function pretty much the same, with Teslas, despite the fight from the established car manufacturers, there is night and day difference between the efficiency, range, convenience, performance, safety, and charging infrastructure.
Performance wise the Model 3 seems ideal and I do like the frameless windows. Not sure whether stereo is decent in the SR+. Did not know you could refuse delivery if too many issues...
