I have a 22 LT 6.6l gas with 2500 miles took it to the dealership because it seems to excessively crank in the morning 3-4 seconds until start otherwise fires right off during the day,tested battery at my house showed low voltage dealership had it 2 days couldn't say it was the module keeping bcm awake but blamed my dash camera I've keep it unplugged so not to drain battery and back from the dealership still excessively cranks,I'm thinking bad battery but am going to take it to another dealership since I have lost faith and the actual diagnostic test they did at the dealership I brought it to first,just seeing if anyone else has had an issue of battery drain overnight or excessive cranking
