They’ve tested my battery load tests fine so they won’t replace it. I leave the fob in mine every night. The thing I don’t understand is it’s set for a weekend and had no trouble but I’ve moved it 15 feet on two occasions and been completely flat the next morning.
On two separate occasions the battery has went completely flat on the truck. Charges up and then is fine. Both times the truck has been started moved a short distance and then parked for the night dead the next morning. Both times coincidentally have been towards the end of the month when the onstar diagnostic email comes out. Any ideas?
