Sent to a local Hyundai dealership, 210322, in response to the flood of mailings
I kept getting from them about Recall 196 and how urgent it was.  I called bullshit:

Subject: waiting on campaign 196

Hi, I was told that I can use this email to reach the service management of
your organization.  I want to clarify a couple of things about Recall 196,
which applies to my own vehicle.  I have received several notices and letters
about it, and am quite familiar with the situation.  In fact, I am familiar
with some aspects of it that your staff may not be.

The procedures and explanation behind this keep changing, and it is mostly
because Hyundai is not being straight with the public as to what's going
on with it.  Bottom line, the battery packs have to be replaced, to get the
potentially defective cells out of there.  In the meantime, Hyundai Korea
has been extraordinarily tight-lipped about it all, shifting blame to LG Chem
and anybody else they could finger, and giving more priority to some notion
of "saving face" than actually being clear about the problem and fixing it.
We have several horror stories about ECU reflashes not being performed right,
failing halfway through due to 12V auxiliary batteries going dead and
completely "bricking" customers' cars, and/or reduced range from artificial
charge limits as temporary guesswork toward safer operation.

Every dealership service department should be up in arms about this, telling
Hyundai corporate to stop screwing around and misleading the public.  It is
insulting to the dealerships that they are being made the public face of
Hyundai's failings.  These interim ECU update band-aids are clearly not the
right answer, and from what I understand Hyundai is slowly facing the fact
that they have to replace on the order of 80,000 battery packs worldwide.
I run some OBD-II tools and have deeper insight into the state of my own pack
than most drivers, and my cell voltages have never deviated more that 0.02V
from lowest to highest.  I generally limit my charges to 80% anyway, so I'm
not particularly worried about overcharge situations in the near term.

Some of the reflashes also change functionality in an undesireable way, for
instance no longer allowing disablement of the "battery saver" feature which
has proven to do more harm than good.  Thus, only controller functionality
directly related to the *high-voltage* battery management system should be
messed with, and other existing firmware left alone.  The TSBs describe how
GDS allows separation of those updates into individual procedures, rather
than trying to run the "batch".

So until such time as your service department is tooled up and trained up to
replace packs, i.e. having the appropriate lift table and related gear and
the ability to order and ship the replacements, I see no point in bringing
the vehicle in.  Last time I was in there for something minor I was basically
treated like a child, told to go wait in a corner without having my questions
answered to satisfaction.  When your senior people can assure me that they
can do these replacements and ancillary work per MY choices as the vehicle
owner, without treating me like a second-class citizen in the process but
instead exhibiting some level of tech-to-tech respect in our conversation,
I'll think about it.

Attached is a shot of the label on the rear of my pack, for reference.

Thank you
