You're asserting that it's extremely buggy yet offer no evidence other than to Google it. When you Google "bmw infotainment issues", "gm infotainment issues", and "ford infotainment issues" you receive the same pages of results.
GM is currently facing a class action suit for the infotainment system in 2019-2020 vehicles. Ford settled a class action lawsuit for its MyTouch Infotainment system and Consumer Reports failed to recommend the new F-150 due to the Sync3 Infotainment system. Subaru also has a settled class action suit for its infotainment system. BMW iDrive is pretty much universally reviled.
The Tesla Infotainment system, warts and all, is considered one of if not the best.
Not to say Tesla doesn't have these issues, they probably do. Thing is if you go on Google and type "X issues" you will almost always find what you're looking for.
There are too many unique issues for me to point at one.
Did you really want me to copy the first 10 links on Google?
