[QUOTE="Bigbadbow, post: 18165, member: 6109"] So my new to me 2021 premier with all the boxes checked sans towing and 2.0 had a battery drain issue that looks like it’s not fixed. The dealer replaced the battery and said it had a “bad cell” but I’m thinking it has a intermittent cold weather stays open circuit. I opened the tailgate from the remote at 6:30am and than closed it (by the tailgate button) and I though I had locked it. Came out at 4:00pm and the car wouldn’t remote start? Tried the unlock but car was already open tried to start it and everything was dead. Checked the battery with a volt meter and it showed 4 volts basically losing 2/3rd of its voltage capacity in 10 hours or so? Jumped it with my jeep and 1st it took forever to allow me to even start it but while waiting it kept flashing the Cadillac logo on the info screen and than after starting it I got a “calibrate device” screen and it was locked. Any techs get on here? My gut is it will show up again as this is the second battery in 12 months and only 23 months of service it was in the upper 20’s when this occurred.[ATTACH type="full"]1789[/ATTACH] [/QUOTE]
