Auto start stop not working

Just picked up a new 2016 cruze premier. The auto stop start has not worked yet and i have 100 kms on the car now. Any ideas? Even the test drive with another cruze didnt have the auto start stop working.

I checked out the manual and have found nothing.

Auto Start/Stop won't work below 41 degrees. There are other conditions that must be met as well before it will function.

Can be related to the drop in weather. If it's below a certain degree. The computer will stop auto start and run the car as regular.
Ok. It was 35 degrees outside yesterday or plus 2 Celsius

It also wont if the Check Engine Light is on, which was my case. Which also happened to be due to the electrical system because of the recall
Anyone know why start/stop wouldn't be working? It's 46°F outside according to the car's display and just got it back from the dealer
Are you running the fan? I've noticed Auto stop will not work for me if I have the heat on. When at a light if I turn the fan off (Yes AC is completely off), Auto Stop is engaged. If I turn the fan on, it starts up.
Auto Stop seems to be finicky. I can't even see how beneficial it is. For me anyway. I'm never at a light long enough to see the benefit.
Just my 2 cents.
You might be right. I had the temp set to right between the blue and red and it was more towards warm when I picked it up today from service.
lately, when I have my fan running, I turn it off when stopping to get the auto stop to work, and then turn it back on right before I want / need to get going again

What kind of service work did you have done? It may or may not have anything to do with Auto Stop not working, depending on the work performed.

It was the recall work but they had to actually fix the issue rather than prevent it. Then realized my temp setting was on between cold and hot and it hadn't heated the car yet. After class I turned it to cold and it worked just fine

Well we got to plus 7 Celsius here in canada. My auto stop start now works. Although it seems to be touchy on when it works. It will work at a light and then the next light it wont.
