Presumably, but you don't really known until you pay to take it in for service and they tell you there is nothing wrong but they don't have a fix (gee, great experience). On the "know it's software" side e.g. I had what appeared to be random issues with audio crackling on my PC I assumed was software/driver related, it turned out there was a faulty USB hub causing an issues for the whole bus but it was just most apparent in the audio device.

Stuff like "Doors refuse to open" is vague enough it could be a similar kind of issue which needs physical service/replacement rather than just a software update, especially if other buttons are triggering completely separate actions with the windows. Or it could very well be 100% software issues, which could be more apparent with additional details like "only does it after transitioning from this screen or pressing things in this order" type problems.

As a car guy you should know that there's tech in cars these days. Or do you calibrate everything from tpms monitors to re pointing/tunes in your garage?

If something's wrong with your car's head unit firmware or android auto connection or whatever, of course you'd have a technician look at it?
