So if I understand you correctly, all Summits (2011 or 2012) have QDII, even thought the window sticker does not show it as an option or include it in the list of standard equipment? Why would Jeep do that? Is there a way to see something in the interior or in an option code somewhere that it's definitively "in" the Jeep?
Also--if the Overland has QDII (whether a 2011 or 2012), then does that also mean that it definitely comes with Selec-terrain *and* Quadra-lift, or must those be ordered separately for both model years?
Finally--what causes that shudder? What is it about the 2012 that gets rid of it? Was it that prominent in 2011?
Yes, 4x4 Overland Summits with V8 Hemi engine (both 2011 and 2012) come standard with QDII despite what the window sticker says. They are QTracII + ELSD = QDII. The EVIC display (when you start it up) that is located between the odometer and spedometer will say Quadra Drive on any so equpped Grand Cherokee. Also, I don't think any Grand Cherokee with the V6 engine has QDII (not sure though).
Selec Terrain and Quadra Lift are standard on all 4x4 Overlands (with or without QDII). However, VERY early build 2011 Overlands did not have Quadra Lift.
Selec Terrain is standard on 4x4 Limiteds.
