Anyone have battery problems after the update for the recall? I took my 2016 Silverado in last Friday to have the Recall and a Radio Software update done. Up until that point, I had never had a single issue with the battery or starting. Over the weekend, the whole thing went to crap. The radio keeps blinking in and out, and the truck won't start unless it is jumped. I stopped at 3 Parts Places and had the battery tested, and all 3 said it tested OK, but needed charged. I had also left it overnight on a 2 Amp Trickle Charge and this morning it still wouldn't start. If anyone has any ideas, please let me know. Parry
