The big automakers collectively ship defective vehicles by the millions as a matter of routine business and have been doing so for as long as there has been an automobile business. They're going to continue doing so. You'll regularly get pieces of mail from companies like Nissan, Ford or Hyundai, telling you to bring your vehicle in, years after they sold it, to fix mistakes.

Most of the other automakers will just leave you rolling around in a defective 3400 lbs pile of metal for years until they get to a fix or finally figure out there's a problem.

Tesla was able to quickly improve its product with a software update and without inconveniencing its customers. It's a superior solution.
