I do not visit this site very much. I should have though because now I see how much I can learn about my 2012 Volt. I love my Volt. I drive 1.6 miles to work everyday. It is perfect for me. I rarely drive over 10 miles a day. Recently batteries have not been charging as they did 1 year ago. Before I was getting at least 42 Mi EV on each charge. Now I am getting 34 to 36 if I am lucky. Has anyone else had this experience? Also tire pressure sensors seem to have gone awry. I took it in to my Dealer because one of the tires was showing 6 lbs lower then the other three. They said they fixed the problem. Now that same tire is showing 6 lbs higher than all the others. The other three are coming up in my msgz as having low tire pressure. Send me any info I can take with me to the Dealer this month when it is time to have it inspected.
