There was an interesting aside in the full article in Which Magazine though:
"We discussed Land Rover in more detail back on p15, but Tesla remains the paradox. Near the bottom of our table, Tesla cars sport some of the highest fault rates (40% of owners with cars up to three years old) and longest average garage stays (four to five days) we've seen. And yet Tesla remains the most-loved brand: when questioned on satisfaction and whether people would recommend their car to another buyer, Tesla came out on top, beating Porsche and Lexus. It must be doing something right."
Probably a phenomenon most people here would recognise!
They also raise concerns with the Model 3, saying:
"Admittedly, the faults tended to be minor, but it belies a general low level of quality: paintwork and other exterior trim problems were common, which is unusual. Although not overly frequent, a number of owners also reported problems with the car's rainwater seals. The last thing you expect from your fancy new Tesla is for it to let in water.
Then factor in that 3% of owners we heard from had already seen their car break down. The Model 3 looks destined to go the way of the Model S and Model X."
