Hi I have a 2015 mazda cx5. I have noticed that the accelerated warm up system has been intermittent since I brought the car in September but I understand it is all related to temperature of certain components. However the last few days with the change in temperature and the cold weather I would imagine that these would be the prime time that the AWS would kick in. Yet the past week it hasn't happen at all. This morning for instant was the coldest morning i have had so far with the car only reading 5 degree and the was no accelerated warm up when starting up the car. In turn I have noticed my fuel consumption has also been awful this past few days. My drive to and from work is 5 miles yet my fuel consumption has been dropping like 15 to 20 miles on these trips something that it isn't usually like. Could I have a fault with the AWS??? I did have a recall on the car where I had to have the soft ware up dated i could this have had an affect?
