2012 Cruze Eco
I have had this car for 5+ years. I am one of those guys who listens to the starter motor humming and starts the car after the humming stops.
Yesterday, I noticed that the humming does not stop. If I leave the key in position 2, the humming goes on until I turn the ignition to start. On turning the ignition, the car starts fine and seems to run fine. The humming does stop (or, so I think).
The only thing that changed was that I re-activated OnStar yesterday morning. Could that have updated something that changed the behavior? Or, is something about to break?
The battery was on its last leg, so I went ahead and replaced it yesterday to eliminate any problem with the battery.
