Looks like some early XC 90 vehicles are having problems:

I hope the Signature X's will be ready for prime time when delivered unlike the XC 90. Although I recall some Model S posts stated one can just reboot if something weird happens and it usually goes away? Is this true?
Yes it's true. sometimes the center screen needs a reboot...
Every car brand will always have a few cars do weird things. The more cars you produce, the more cars will behave weird problems or have a manufacturing fault.
It doesn't matter if it's Tesla, BMW, Volvo, GM, Ford or whatever. But the better quality control you have (incl for software), the smaller the number in percent of produced cars will get.
From reading here and other "brand boards" as well as my own experience both with Tesla and other brans, Tesla is actually somewhat lacking when it comes to quality control.
