Starting about the time I discovered "L" mode (about 3-4 months ago, on my 2013), I started to have it happen that pressing the "Drive Mode" button was increasingly working more intermittently, to the point where I could not get it to respond at all during a drive.
I have read countless posts and viewed a number of videos that discuss how the button might be "broken", and how people fidget with the switch fascia to get it to work. Some say this helps, but then the problem comes back.
Worse, folks who witness the problem go to the dealer, where they cannot replicate the problem, or at least simply restart the Volt to notice the problem no longer exists.
I noticed a bit of a pattern in intermittency in my own use - the button works fine early in a trip, and less often over the course of a trip. More importantly, and this is important, stopping and restarting the Volt always restores the function of the Drive Mode switch. I have every reason to believe that this button's hardware is plenty fine, and that there's a software bug that causes the Drive Mode button to stop responding to presses.
If you've had issues with your Drive Mode switch, I ask that you simply restart your Volt and post here if the problem has, even temporarily, gone away.
