Brand spanking new 2016 Tahoe drive it home all good. Next day start it up and head out. Then it starts. The instrument panel illuminates every single warning symbol, then goes completely out (needles return to zero, panel goes dark) and then returns to normal. First day it did this no less than 10 times on that day and continues to do it. On top of this issue, the radio freezes and will not play music nor will any buttons work. Can't even turn it off. Both these things happen every single time I drive it.

Took it to the dealer and they were perplexed even when I showed them video. So they downloaded some update from GM and all was good for a couple days. Now same things are occurring more frequently. So the next trip to dealer will be second attempt to fix. Really irritating they would sale a 60k vehicle knowing there was some issue with the radio. Salesman pointed that little tidbit out after we had signed the papers.
