I had the recall about 3 months ago on our '08 2500, no issues.
All 4 speakers died at least 3 years ago. Same with our 1500.
Currently, all 4 tire sensors error when the temperatures drop. They are about 9 years old so the batteries are getting weak. Will need to replace them with the next set of tires. Not cheap.
Haven't had the other issues you're having.
My assessment is GM's speakers were junk before they were installed. I started having problems with both our vehicles withing 2 years of purchase. Have replaced all with $25 set from walmart (Sony I think) that sound great and are lasting. Much better than OEM.
For us, neither of these issues were caused by the airbag recall.
