OK, here's a question for all of you out there who have driven both models like me. My old Volt was a 13 model. When the ICE came on, it was absolutely a non-issue - I would see it on the dash display, and might even hear it unless I was cruising on the highway. But never, ever, -not once- did it ever have the same experience that my new 17 model has. Today was the first time it has run on ICE for me so far. It came on while I was cruising at 75 on the highway (with the cruise on as well). When it came on, I did notice it immediately - not because of any noise (because I couldn't hear the engine on the new one), but I also felt constant very slight surging as I was going down the road. This feeling did not stop the entire way home, so it was not just related to the highway driving. In trying to describe what I was feeling, I would characterize it as kind of like an engine that had a bad spark plug or something which would cause it to miss or something - you'd get an uneven delivery rather than smooth consistent power. I was just wondering if others have ever noticed this? Or if there are others out there who have driven both generations like me, and noticed anything tremendously different like this? My car has very few miles on it since I just got it a few days ago, and very few miles driving under gas. I can say that the test drive car I drove actually went on the ICE as well while I was driving it, and I never noticed it. So I'm wondering if there might be something not quite right with mine? Anyone have any similar experience or thoughts?
