Did you get stuck yet? ETC light!
Well if you didn't, there is a good chance that you will! From my experience and studying up on the situation, a lot of folks are getting the dreaded red lightning symbol light on the dash along with a loss of power ( limp mode )! Sometimes you can temporarily help this by shutting down with the key off, then restarting. However, this seems to get worse and more frequent. Codes really don't come up except P2173, which doesn't tell you much.
In my case I went ahead and replaced the Electronic Control Body, which seems to be the internet/utube solution @ $250, and we will see what happens.
So far approx. 60 miles with several on off cycles, and all appears to be normal.
