Looks like GM has a fix for the ANC reverb issue
I just got my daughter's car from the dealer and they applied TB-23-NA-194 to reprogram the Stereo System.

I tried to make it go off and was not able to recreate the problem. Drove in highway and city at different speeds and loads. I consider the issue fixed, it is gone for good.(y)
I’m pretty sure we have same issue. I’m taking my car in soon and I hope this works because that bass noise is so annoying. Also. an entire different issue, my 24 Trax has been making a buzzing and rattle noise, it’s coming from inside the cabin on the passenger side. Sounds like it’s coming from above the cabin filter have you experienced this?
