Hi all, I'm in the UK and someone from the other forums mentioned this thread. I've had similar problems.
Picked the car up mid Dec. A week later we had our first trip, in freezing fog (about 1Deg C outside). Got about 100 miles into the trip and all was fine, we charged and set off only for the climate control completely die on us. We stopped, rebooted and no change. So we ended up driving for 70miles in outside cold temps blowing in the car....not fun at all.
We stop, do the service request etc. I go back to the car later in the day, check it, and its working again. I leave for the ranger to come the next morning, he comes over, says there are no errors and that its working fine. Either way I book it in for Jan 10 for replacement of pressure sensors or something.
I've not had the problem since, but have noticed with climate control on it blows hot, then suddenly has the odd minute of colder air, then back to hot. Its like its trying too hard to heat up, then realises the temp is too high in the cabin, so blows cold.
Either way, the problem hasn't come back since so I delayed the service appointment to Feb. Have to see what happens.
