2022 Equinox-On Star light Red intermittently

I am having the same exact problem with my 2021 Buick Enclave.  I have taken it to the dealer four times (although it has happened far more time).  The first two times, they told me to bring it back while it was having the problem.  The third time, which was only a month ago, it was having the problem and I drove straight to the dealer.  They did a software update and gave me the car back.  Now, exactly one month later, same problem.  I brought it in again.  They said they can't duplicate the problem so they can't help me.  It old them the previous time it was not working when I brought it in.  I was told "well that's because it brought it in later in the evening on a Friday"  It was 5:45 which is when it started having the problem.  I guess they didn't bother to try to fix it when it broken, just turned it off til the next day which will reset it and it will work again and the red light will go back to green.  The problem is intermittent but it's a big problem.  I called GM today who started a case for me.  The very nice rep called onstar who told her there was a module malfunction.  I called the dealer back and they don't seem to believe me because while he was on the phone with onstar he was leaving me a voicemail so I heard him questioning about whether someone would have told me there was a problem  SOMEONE DID!  The GM rep who called onstar for me!!!  I have a case number! I am ready to trade in the car for something that is not GM at this point.  I am very frustrated.  For the amount of money we pay for these cars, the features should work all the time or certainly be repaired when they don't.
