Importantly, the TSB means “this is a fix for if a problem is observed or mentioned.”
The “Lower A-Pillar Speaker Distortion” fix is a TSC (TSC-B0824-001-01), which means “do it the next time the car is in for anything at all, period” so eventually every car will get this done the next time it is seen. Not urgent, but at your annual or whenever you bring it in next for service; think of it like the bear decal campaign before they were shipped with every car. You don’t get to bring it in just for that, but while it’s there for whatever else it’s there for, they’ll apply your bear decals (unless you told them not to), and they’ll swap the tape on the lower A-Pillar speakers too.
