When I had a Model S for an overnight test-drive I had no problem giving it voice commands. But now that my vehicle is delivered the experience is quite different. It almost always says "Recording Unclear". Only when I lean over and shout does it occasionally get what I'm saying, although even then it results in an "unknown command" most of the time. Is this typical? Should I consider bringing it in to have looked at? I was also a bit disappointed with how few recognized commands there are. I'd have thought that "open/close roof" would be a no-brainer, among others.
