I have a 2010 Mazdaspeed 3. When it gets below -4C or so outside my power steering stops working, my light comes on in dash and it won't start working until the outside temperature comes up again. The dealer checked my wires and cleaned them up a bit and of course by the time it left the warm shop it was working again. They said if it still did it again I needed a power steering pump. I figured if the pump was bad it would act up all the time. It did it a few times at the end of last winter but was good all summer. Just wondering if anyone has dealt with this?
