I could turn off the engine after driving, but the key stays in the position between the engine being on and the car being off (for example when you can listen to music but your car isn’t running). The battery light came on after the issue started and so the car service place charged us to replace the battery, because they had to turn on and of the car a lot and the car had to continue to run. I took it to a car service place and they ran tests and called Chevy test support to run diagnosis tests. They can’t figure it out. They think it might be the body control module. Not sure what that is. The car only has 31,000 miles on it and this is a safety issue because what if this happens and the steering wheel locks or it becomes a rolling hazard. This would affect the driver and others. There were no lights or errors indicating a problem before this happened.
