For a while. Trying to think when but I know the tahoe and avalanches had them since 05? Colorado and Canyon have them. My Impala (12) has it and for at least 09 if not earlier. I just picked my wifes 14 Malibu up from the dealer a couple hours ago because of the battery crapping out. It has a massive AGM battery because of the stupid auto stop. They said the battery would have been $363. 1 more year and that car will definitely be going.
