I own a 2017 Volt and a few days ago, during a cold winter day with my Volt plugged in at home on a L2 charger in my (attached) garage, I used my app to pre-heat my Volt. When I walked into my garage, I was horrified to see that the engine was running!! Inside my attached garage with the main garage door closed!! This is a very serious and dangerous situation!! Is there no way to configure the car to NOT start the engine while plugged in at home?? If the car is not intelligent enough to know that it’s at home, I would settle for the car not starting the engine EVER due to ERDTT if it’s plugged in to a L2 charger.
