My 2011qx56 has no throttle response at all.I started it up backed out of driveway and when i turned the wheel it just made a dragging noise in rear by the diff.I put it in drive and when i accelerated it felt like the car was not moving.I had to limp it back in driveway.When i stepped on the gas pedal the rpms would not go over 1000.Any body with the same problem.I have 44000 miles so it should be warranty.
 
standard procedure: pull any DTCs from the obd. since its under warranty, let them handle it.

could be a TCM/ECM issue.

do you have AWD/4WD? what trim options?
 
awd/4WD.No check engine light on.

When in park or neutral no rpm problem only when in gear.

engine lamp does not have to be on for there to be a problem.

if you can, stop by an auto parts store and have them check the obd port.

Here we go.The tow truck arrives to tow to dealer and i move it out of driveway to line up with flatbed.the rear starts to chatter and then I noticed on dash it was in 4WD. I put it back to auto and I said let me go around the block.Sure enough there it is.It apparently went into limp mode when the traction control sensed dry ground.My wife said the pocketbook must have moved it and I laughed.well she runs perfect again but I blamed myself for not checking it.
 
well when its in any other mode other than auto, it should beep when you start the car.
