Welcome, no extended warranty for me but.. a few others here have had good luck with a few 3rd parties.. I will search around for you myself to see if I can find anything for you.
I would imagine the truck's ECM had an update available, and they went ahead and hoped that will fix your issue. I wouldn't bet on it personally..
But yes, if they continue to say ECM I would make them replace it..

I'm tired of baby sitting. Please keep this on topic and to the point. WE ALL want to know what's going on with the '17's, and fighting an complaining online like school children isn't going to help us.
The next one out of line gets a vacation. I'm a one man army here...
