Chevy did a lot of repackaging for 2012, the 1LT got the biggest changes, but you're right that the LS did gain the power mirrors. I've sold a bunch of Cruzes and I can tell you that more customers asked for cruise control on their Cruze than power mirrors. I find it ironic that you cannot get cruise on a Cruze (LS).

 

I thought they all had them, even the cheapo Eco has 'em. What? Even My Eco has cruise.

 

my 2011 ls came with power mirrors

 

Your's is some kind of exception then, or a very, very late 2011 where they had already instituted some of the 2012 changes since there was no shutdown at the factory between model years like GM normally does.

Nope! But the LS was the only model where they were not standard or available.

 

My 2011 LS doesn't have power mirrors but since I'm the only one who drives the car it's not that important. Once I got them set the way I like I'll never have to touch them again unless I move something accidentally.
