same problem. glad to finally have pinpointed the problem. best example:http://www.youtube.com/watch?v=pOX-ufuwYiE
only 33k miles on my 2011 Pat FDII. I've read the CVT fluid replacement nor the (oil) cooler solves the problem. i have a service appt scheduled friday, but it seems a wash; i'm over my 3 year (not that it matters as they're ghetto and will invariably pinpoint a knee jerk remedy not covered); definitely not going to pay their $150 charge to diagnosis (insult to injury).
so for me, it's intermittent, only when hot and especially uphill climb, like clockwork. what's best course of action? I'm thinking I will sell this lemon and never look at a Patriot again; whole GD point of FDII was climbing. But this broken CVT kinda rules that out.
