The tweeter speaker in the driver side A-pillar stopped working recently in my 2023 CX-5 S. Less than 30k miles on the car. Anyone had a similar problem and found a fix?

 

Ypu are still under warranty and should go to a Mazda dealership. If you tamper with your sound system and damage it or other related system connect electronics you could loose that part of your warranty protection more then just the sound system.

 

Had a similar problem with my 2014 CX5 GT while it was under warranty. Dealer fixed it with no problems and it's still working ten years later.
