I have had my 2008 Malibu with the 3.6/6-speed do something weird the last two times I have driven it. When coming down from a 60 mph cruise to a stop/almost stop the transmission seems to go into neutral and the car won't move when I press the accelerator. If I then let off and slowly squeeze it will go. I don't think there is anything mechanically wrong and am wondering if someone else has experienced this and had it corrected. I am hoping it is just a software change.
