No power 2011 gmc Acadia

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. So sorry to hear you're having trouble with your vehicle. If your Acadia lost all power and won't respond even with a jump start, the issue could be related to the battery cables, the main fuse, or even a faulty ground connection. Since you've already checked the fuses, I'd suggest inspecting the battery terminals for corrosion or a loose connection. Also, check the ground wire running to the engine block to ensure it's secure. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
