This sounds very similar to the nightmare I went through with my 2005 last year;
and I had the misfortune of a tech who could not diagnose. That was when I got
the scan gauge and discovered the battery was showing hotter than normal.
Luckily the second dealership had a tech who was able to figure it out. My
problem turned out to be the controller unit that controls battery cooling and
apparently is inside the battery case and therefore required full traction
battery replacement to repair. It got replaced on warranty, which was an
incredible relief. The traction battery system has worked well since the battery
replacement.

It might be helpful to the rest of us to get the exact diagnostic codes on your
report from the dealer.

And to those who remember my MEC pump problem; I have the replacment pump and am
waiting for the time to replace. The replacement pump is very tiny and probably
a tenth of the size of the original pump and housing with the same attachment.
The replacement is a lot less elegant solution than the factory original and is
assembled in Mexico.

The original works ok on small trips, but is erratic and does not keep the
trans and electric motor as cool as it should at times, so I am not doing any
major road trips until it gets replaced.
