I drive a 2012 Mazda I touring skyactive. While driving home about 45 mph when I was came to a street light. As I applied my brakes the transmission shifted down hard, the traction control light came on and the transmission disengaged, which forced me to pull to the side of the road. The transmission type is an electric auto/manual. With the car still running, I put the car in to manual mode and nothing happened (no power). Only after turning the car off and restarting it did the traction control light go off and the car ran as normal. This is nothing I would want to happen while on a thruway. Also, over the past few months I have noticed downshifting hard one in a while, but not enough to take it to a dealer. After to night, I will be taking my car over to the dealer in the morning.
