Well, it's still leaking. I'm at 50K miles now.. I'm assuming warranty is still in play here. I worry about any parts being back ordered sadly. I will likely take it back in this week.
My Wifes 22 Tahoe (same infotainment system as the refresh trucks) is one of the worst functioning systems I've used. It's glitchy and works 2/10 times when I drive it. Freezing/etc.
Seems a bit dangerous.. The only relation I can say I have is when it's in regen mode it seems to be a bit toucher on the throttle and can seem like it's jumping. But I'm talking about a few hundred RPM's, not nothing massive like you're mentioning.

I'm not surprised, as most of those owners DO NOT care about fuel mileage, which is the #1 selling point of the 3.0L Duramax.
A bit pricey that's for sure, but it's great to have more options.
