stop/start not engaging

4621 Views 2 Replies 3 Participants Last post by  SmithR
In recent days my stop start hasnt been engaging when I stop. Typically it is more active in cooler weather than it is in the summer when the AC is running and the system prevents engine stop to maintain cabin comfort. Not sure what is going on. Wondering if anyone else has had their system stop functioning normally.

GM did reportedly add a way to disable start/stop in 2020 models. If that's a route you want to go.

What year model is yours?
Sometimes if the temperature is too hot or cold engine start/stop features might not work.

This is from the owner's manual.
