I have had it to the dealer 3 times, they have no clue how to get it to stop. Mine has been doing it for a year. GM has never figured out what is wrong with this information center and now has a new one good luck. And I forget I was a member here and just like that I deleted my Alexa app and that flashing light is gone. Thank you. I got my 2020 Silverado built just before everything was shut down and it been the best truck I have had with no other problems other than this.
