There is a service bulletin scheduled to be released 06/04/2012 that involves 2012 WD, DX, DJ, D2, DS, WK, DD - Drive to Neutral Shift Shock. I have not seen the final approved version, so I do not know if it is applicable in this situation. Also, just because something is scheduled to be released on a certain date doesn't mean it will.
There is a Bulletin number: 18-015-12
that came out April 20, 2012.
Flash: Bump Or Harsh Shift Neutral to Drive And Avoid MIL Illumination For Any P0032, P0038, P0052, P0058, P0031, P0037, P0051, P0057
This bulletin involves diagnosis and selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software or if necessary replacing the PCM based on the DIAGNOSIS. This new software once reprogrammed in the PCM will prevent the need to replace the PCM when the diagnostic trouble code (DTC's) listed below occur as a pair.
2011 (WD) Durango
2011 (WK) Grand Cherokee
NOTE: This Service Bulletin applies to vehicles equipped with a 5.7L engine (Sales Code EZH).
The customer may experience a MIL illumination or a harsh shift from neutral to drive.
