Just got a 2011 Aveo and threw it in park and it was in fact not in Park. Had to unlock the shifter and row down and up again.
Is this an adjustment or something worse?
Edit: I could not find adjustment instructions specific to the 2011 Aveo so I just removed the center console, saw nothing, so had my someone wiggle the lever while I observed the engine bay. The mounting bracket was loose. Works much better now. Can't get it to not engage anymore.
