There's no doubt that the Tesla Model Y isn't a perfect car, no matter what all the fanboys would like to say. However, the thing I have come to realize is it does the best job of alleviating all the potential problems of electric cars. It is intuitive, well engineered, capable and extremely efficient. All other cars right now require significant concessions or have notable downsides to them. The biggest one is the charging network and experience. It doesn't take long at all reading around the web or watching YouTube videos to find all the horror stories of Electrify America, EVGo, Chargepoint and others in the US. Things are different in Europe, but in North America the Tesla network outshines the rest by a country mile. To me, I have to have the confidence that when I show up at a DC fast charger, that thing is going to work, I'm going to get charged up, and I won't have to sit there for 2 hours to do it. Beyond that, here's things I've found in my research of competitors:
Mach-E: tons of software issues, phone key problems, they built them for a year with a battery contact module that is guaranteed to fail, and requires the entire battery to be removed to fix.
ID.4: even worse software problems in the car, like horrific failures, sometimes bricking the car, that still only may be fixed in the latest update, but maybe not
Ionic 5: smaller than the Y, doesn't precondition the battery so charging speed is a tossup, phone key on iPhone apparently has issues
Volvo: smaller than the Y, less range, for the same money
Q4 eTron: just a more expensive ID.4, a little nicer, hopefully gets better software than its less expensive sibling, audi app has issues, I could see this being tempting though
There are forums for all of these cars, just go read up on the common problems people have with them and see if they are deal breakers for you. I know for me, crappy onboard software, a lousy app, features that don't work, plus charging issues would drive me insane after dropping $50K+ on a car.
