AirPods Pro 2nd gen case showing liquid damage without exposure

Because of this, the Transparency mode has started making a buzzing sound, and I was informed that the case has liquid damage. I am very concerned because I have kept the device well-maintained and it’s still under warranty. Hello, I recently noticed that my AirPods Pro 2nd Gen case is showing signs of liquid damage, but I want to clarify that I have never exposed the case or the AirPods to water or any liquids. The AirPods and case have always been handled carefully.
