With all the cooling pipe and drive shaft failures, I decided to take a peek at the Dept of Transporation Safety web site, to see if there's anything on these issues. Turns out, you can search the complaint data base, and lots turns up. On each case, you can click the summary, and see in more detail the issue. Here's the link:

You can also leave your own complaint if you wish. Apparently, doesn't do much good though, but might make you feel better.

a borascope huh...hmmmm

So does anyone know of the progress of this situation I would like to know about it in detail.

Good going! This should help getting PCNA to address a known failure
