It's about "green" lead-free solder has caused problems. It think the
money quote is this one:

"And if you think this problem is minor, I have been told that just
the cost of changing to lead-free solder stands right now at $280
BILLION and climbing. That cost is borne by all of us."

It even has some metal content...

I think nearly all the electrical connections in a car are solderless
compression fittings. If they aren't they should be. Done right it
makes a better connection than solder. That means using the appropiate
connector and the tooling that they were designed for. NOT those
idiot "multipurpose" thingos. :-)
...lew...
Virtually NONE of the connections in/on the microprocessors and
associated controllers (think Can-bus) are constructed with crimp
connections. They have ciecuit boards, which are soldered. Leadfre
solder is a total pain in the butt to work with, and ALL devices to be
soldered with lead free NEED to be specially made for lead free
solder. The problems with lead-free solder in electronics assembly are
legion.
