Picked up our 2015i. Don't have too many miles on it yet. But so far, zero indication of the pressure issue.
Specs of our truck that may/may not cause/prevent issue:
Yukon
Delani trim
8 speed
Short box
no roof racks
sunroof
No issue with audiopilot both on and off
20" wheels
Oh, and I really like the 8 speed.
