Default 2012 Suburban TSB's?

I just bought a 2012 suburban. I just joined and did some searches but dont see any posts that list the TSB's for 2012 Suburban's. Maybe I am missing them?

The passenger side rear view mirror tilts during reverse but when I put it in drive, the mirror goes way up and I have to adjust the mirror every time I back up. I would think this is not how it is supposed to work?

The Burb also idles pretty rough.

Any help will be appreciated.

There's programmable positions for the Mirrors and Seats. Driver 1/Driver 2...like that. You need to look in your Ops Manual, or go to GM and they have them online to find out how to set the memory positions for your ride.

HA and yes, the Mirrors do change position between Drive and Reverse on mine to, but I don't know why. As long as they're right when I select Drive is what counts

Rough Idle: 02 sensor, Plugs, maybe more ?

papaglock Welcome to the forum...

Not all TSB's can be found online or for free... you might want to take a look at All Data DIY -> ALLDATAdiy.com Leading Source of Factory Automotive Repair Information as they have a listing of TSB's and all of thier info is current and up to date....
However since you have a 2012 you should still be under warranty, so I would take full advantage of that and get it in to the dealership... the idle could be as simple as a software update...

Here is a link to a list of current GM TSB's not all will apply to any one vehicle nor is it a comprehensive list of all..

Unless you parallel park a lot, I'd turn the tilt down feature off to prevent wearing out the motor.
