Hesitation/Power Loss

I have had my 2012 Volt a little over 2 months. I absolutely adore it, but it is doing something that gives me cause for concern.

I have noticed that it occasionally seems to hesitate or lose power for a few seconds when it should be accelerating. It seems to happen most often early in a drive, usually when I am running on battery power. I press the accelerator, but the car doesn't accelerate. Instead, my speed drops, and there is a 1-3 second hesitation before it "catches" and becomes responsive to the accelerator again. Needless to say, it is a little scary when this happens, especially when attempting to merge into traffic. My significant other was in the car with me Friday and it happened twice. I thought he was going to go into orbit, since obviously this is a good way to get run over. (Pressing the gas harder doesn't have any effect, by the way.)

Has anyone else had this issue, or does anyone have an idea as to what causes this and what the remedy might be? The dealership says there are no software upgrades for my car, and they are going to have a service tech drive it after lunch to try to duplicate the issue.

Same issue plus new symptom

hmm... Found this thread. I have been having a similar issue with my 2013 Chevy Volt. About a week ago, driving about 60 mph with 31miles on the charge on cruise control (temperature was about 30 degrees, engine not running, I think). All of a sudden the cruise control went off and, of course, the car decellerated. I couldn't re-engage the cruise control (the CC showed being "on"). And not until I had stopped and turned off the car and then turned it back on was I able to restart the cruise control. This has happened again a couple of times. Today, while maintaining speed, at about 60mph, about 28miles on the charge, temperature was about 11degF (not on cruise control) the car hesitated for a few seconds a couple of times within a few minutes. The cruise control did not work at this point either. Later, after the car was off, it worked fine again. I plan on taking it in tommorow, but was hoping I could go in with a solution... Replacing the transmission seems extreme, but if it works...

Hello sdjames952,

Oh no! I can see how concerning this must be. Let me know if you plan to take it to the dealership. If you do plan to take it in for a diagnosis, we will contact your Volt Advisor to have them get involved. They will be able to assist you throughout the process.
