I have a 2013 Volt, have had it for a year, 26000 miles on it. No problems, runs great, but three times I've come out to find all four windows down! I know they were up when I put it in the garage and plugged it in! The first time it did it, I thought maybe the car thought it was hot inside! It has since done it twice more.... now it's getting strange! Anyone else had this issue?
