front USB will not recognize USB 2&3 flash drives

[Wally Nussbaumer]

It seems the new Silverado has  a problem recognizing various USB memory sticks that play in other GM vehicles.  I took samples that play in my previous Sierra (2015) and my wife's Chev Cruze all sticks play without problem.  I also tried them in various 2019 and 2020 Silverados and Sierra's on the dealer lot some sticks played some did not.  It would seem GM has a problem they are ignoring blaming the sticks for the problem.  If the sticks are formatted correctly as per GM specs, and play in some vehicles but not in others, there IS a problem!  I have complained to the dealer but have hit a brick wall.  Complaints to GM have been escalated, but so far no response.  I know it is not a major problem to GM, but extremely annoying to me!
