It is not unheard of for a brand new battery failing. The symptoms you have described are typical of a bad battery. The low voltage causes the cars onboard computer to malfunction resulting in all sorts of messages. This happened with a bunch of us who bought the early model VW Touaregs. Even if there was a severe drop in temp and the battery was sensitive to the temp change and reduced its voltage output, it would result in all sorts of warning messages. I bet you will find they end up replacing your battery and all will be fine. Don't worry too much about it, although I am sure you are a little miffed as I would be too. I have had mine for just over a week now and love it!
