I have had the battery go completely dead 3 times since buying the 2019 Ascent Touring in March 2019. When it goes dead it is so dead that the trickle charger will not work, so I have to jumpstart it then trickle charge. Nothing has been left on or open. I have noticed at various times when I have been in the garage hours after turning off the car I will hear a noise from the rear hatch area. Then it will go off. Opening and closing the hatch does not change the sound. Just wondering if anyone else has had a problem with the noise and the battery failure.
