TL;DR - they used a data scraper to pull data off a public forum. That's about the least scientific way of gathering data. Start here instead:

And then bounce over to the NHTSA's website for real statistics. There are exactly zero manufacturers who don't have any hiccups, especially with a new generation of vehicles. Even Tesla has their fare share of problems.
The data seem to match up. Teslas have been problematic (and inherently unsafe) since inception.
