Batteries too hot?

MINI E #304 has been in the shop for 2 weeks, ever since it stopped running with the evil red battery symbol on the 20th.
I got it back on Saturday and it seemed to be running well. Still no word on exactly what work was done to it over the last two weeks. We took it out to the Movies saw Avatar what a great movie. It was frigidly cold outside hovering around 20 degrees but the batteries never dipped below 60 degrees, and the heat actually felt a warmer then I remember it feeling before the service. The range was low only around 60 miles with highway driving, but otherwise it was fine.

I didnt get to drive it on Sunday, then on Monday I went to drive it to work and I got the evil red battery symbol, meaning the high voltage system was disconnected. I had stored the car in my garage which was cold 38 degrees according to the MINI E. I thought the batteries might have gotten a little cold, but not too much, only when I looks, it told me the batteries where at 167 F degrees.
Well it looks like the battery temperature gauge is broken and #304 needs to go back to service.. again. I had to rush to work so I'll be calling the tow truck this evening if I cant get it running.
