We have 3 2015 Chevy Suburbans in our fleet & they have had their fair share of issues. Most recently one of them lost all power to the stereo, console display & signal indicators while driving down the road. The vehicle was brought back to our office & I took a look at it. All fuses tested good, so I tried reconnecting the battery to no avail. I really couldn't find any mention of the issue in suburbans when I looked online, but there was a post about this issue in the Chevy Cruz. I took one guys advice & removed the fuse for the stereo, started up the car & let it sit a minute while pressing the power button repeatedly on the stereo. Then turned the car off, pressed the power button a few more time. Reinserted the fuse & started the car back up & everything was back up & running.
