Scary. The very first thing they should have said is: please send us samples of the shifted prints so we can have them analyzed and then we’ll be in touch. They should be collecting ALL samples from all effected customers and seeking them out. First thing to rule out is staining of the media itself.
Even the appearance of something like this can hurt printer sales so they better get to the bottom of it.
They are not going to do anything unless numerous customers get together and complain loudly IF many people are experiencing the same thing within the same exact time period something is up.
I would send them links to these posts and posts on other user groups and tell them you are just getting started making this public.
They are going to blame it on the media unless you PROVE it’s happening on all kinds of papers. I can’t imagine it would be confined only to Brazil because the inks aren’t made there, right? So this could end up being a big deal.
By the way, cyan pigment is the very last hue to fade, it’s very stable. I would say the most likely problem with the image warming would be contamination of the inkjet receptor coating. I saw this red/yellow staining occur with Canson Rag Photo when doing bw with HP Vivera inks. The problem was environmental contamination when the prints were shown in public locations for months with no glass in front of them. It was bad. Many contaminants can cause it. One neutral print turned sepia. Same prints in dark storage and framed prints were fine.
Is the paper base itself yellowing? If not it’s not at all likely to be environmental contamination, especially since cyan pigment is super durable.
But this doesn’t sound like an isolated issue. I’m very surprised because they have had such a great reputation for
Ink consistency for two decades. Consistency is everything. And regardless what they say, they are paying Wilhelm a lot of cash to test and promote the stability of their media, which is a big marketing factor.
Really scary, and strange situation, especially if it’s happening to rc media as well.

Geraldo,
Epson's answer is absolutely absurd.
I think it's a case of going to justice, a suggestion, you're good at it, write an article and send it to PentaPixel.
If Epson does not resolve the issue, it is a case of joint action bringing together the affected printers: Burning in Squares publishes these printers displaying to the world Epson's treatment. (em bons português: tacar fogo nestas impressoras.)
I want to see some more printer buy a printer from them.
Abs ..
