Googling "toyota quality control issues" returns news about a recall of 1.75 million cars. So it seems the "reliable" brands have the same problems. Unless we can quantify it better, it's hard to compare.
Except when Toyota does a recall, its just a note in the mail and a little extra work at your next service appointment.
When Tesla does a recall, its a major headline news story and fodder for many forum trolls to use in their rants against the company. (plus, a notice and a little extra work at your next service appointment)
Unfortunately Tesla aren't part of this study.
