Highlighted the most important part of that statement there. And yes, they do, as has been stated multiple times from a dozen different sources.

The TSB itself says that the noise isn't abnormal, it's undesirable. A TSB isn't admission of a faulty part. There's been plenty of TSBs for undesirable characteristics on vehicles that aren't broken or damaged, or have any impact on the car outside a bruised ego. Abnormal indicates there is an actual problem, which there is 0 evidence of in this case.

Also, the "consequent fire" you are referring to was a result of poor workmanship and shoddy mechanics. It has nothing to do with the chirping being discussed here.
