GM L3B engine- thoughts

I noticed that the Colorado trucks are getting the same turbo four engine they're putting in the Silverados, and was thinking that it might be a good fit for off-roading.
Then I looked at what it had:
 active fuel management
variable valve timing
Intake Valve Lift Control
start-stop system (OK, cool)

I've read some of the rants and raves about these systems on this board, and was wondering how the early reliability data on these engines is shaping out. Off-roading is no fun if something craps out and you have to get hauled off of the beach or trail. 

Not that I'm exactly looking for one, yet. There are a few ZR2 models (lockers!) here with the LFX engine that have my interest The quirks of that mill are fairly well documented, but one never knows when a deal will pop up on a newer one, either.
 

As a GM tech, the 2.7T is the best engine that they offer in the full-size trucks, in terms of reliability. It's really smooth and has plenty of power, and we have not seen any major failures out of them to speak of, even as they are now heading towards four years old. The evaporative purge pump is prone to dying rather prematurely, but that has absolutely zero effect on driveability and GM has even offered a special coverage on those in existing applications. I've seen maybe one or two with issues of charge air coolers freezing up in extreme cold in the winter, and that was fixed by a bulletin that included a new shroud for the charge air cooler. Other than that, they seem content to just get basic maintenance and roll on the mileage.
