Air conditioning problems

I made my new Seat Leon Hybrid for a week and yesterday the first longer ride with it. In the middle of the ride the air conditioning, including all the associated points like seat heating, did not go any more. In the digital display this was simply grayed out, the voice control said this point is not available. Also a restart of the engine did not help. Luckily everything works again today, but found it still very annoying, yesterday. Has someone similar problems or is there something known ?
