What NHTSA says
Source: Office of Defects Investigation, as filedIn a letter dated October 2, 2012, Chrysler Group LLC (Chrysler) submitted a Defect Information Report (DIR) to NHTSA identifying a safety defect in approximately 48,058 vehicles built with an axle pinion nut that can loosen, which could result in lock-up of the rear axle and/or separation of the rear drive shaft from the rear axle (NHTSA Recall No. 12V-474).The vehicles involved in this recall are model year (MY) 2009 and MY 2010 Dodge Ram 1500 (46,677) and Dodge Dakota (1,381) vehicles manufactured between July 1, 2009 and November 30, 2009 built with 9.25? rear axles built at Chrysler?s Detroit Axle Assembly Plant. Chrysler stated it determined during this time frame there were instances of 9.25? axles built with rear axle pinion nuts that were missing the adhesive patch. The remedy for these vehicles is to install a pinion nut retainer. In a review of data in its complaint database and data submitted by Chrysler, the Office of Defects Investigation (ODI) identified 194 reports (including 3 crash reports) of rear axle lock up and/or drive shaft separation outside of the scope of recall 12V-474. In a letter dated February 5, 2013, Chrysler submitted a second DIR to NHTSA identifying another safety defect in approximately 278,150 vehicles built with 9.25? rear axles and outside of the scope of recall 12V-474 that could also result in lock-up of the rear axle and/or rear drive separation (NHTSARecall No. 13V-038).Chrysler stated that analysis of field return parts from this vehicle population, undersized pinion splines were found as the likely factor contributing to the loosening of the pinion nut. The vehicles involved in this recall are:266,091 MY 2009?2012 Dodge Ram 1500 vehicles manufactured from 2/28/09 through 6/30/09 and 12/1/09 through 10/20/11 (including 183,421 MY 2009-2010 subject vehicles); 8,475 MY 2009?2010 Dodge Dakota vehicles manufactured from 2/18/07 through 6/30/09 and 12/1/09 through 7/9/10; 2,346 MY 2009 Chrysler Aspen vehicles manufactured from 1/19/07 through 12/18/08; and 1,238 MY 2009 Dodge Durango vehicles manufactured from 1/17/07 through 12/18/08. The remedy for these vehicles is the same as for 12V-474. The failure counts in this resume are for the subject MY 2009-2010 Dodge Ram 1500 vehicles only. The recalled vehicle counts are based on current estimates from Chrysler and may differ from estimates in the original DIR's.This Preliminary Evaluation is closed.

A Preliminary Evaluation is the first formal stage: NHTSA has decided the complaints and other information it screened are worth a closer look, and asks the manufacturer for its own data on the condition. The summary is the agency’s own text from its investigation file, unedited; the opening and closing resumes with the full reasoning are on NHTSA’s site under this number.
What this means for an owner
Source: and what happens nextAn investigation is not a finding that a defect exists, and it puts no duty on anyone. NHTSA opens a Preliminary Evaluation when complaints and other reports suggest a condition worth asking the manufacturer about; it upgrades to an Engineering Analysis when the answers warrant testing; it closes either when it recommends a recall, when the manufacturer recalls on its own, or when no defect trend is found. The agency’s own goals are about four months for a petition, eight for a Preliminary Evaluation or a Recall Query and eighteen for an Engineering Analysis; many run longer.
This one became a recall. The campaign page carries the manufacturer’s filed defect, risk and remedy, the build window and every model year covered; whether one specific vehicle is included is settled by VIN at nhtsa.gov/recalls.

Common questions
Source: NHTSA Office of Defects InvestigationIs PE12021 a recall?
No — it is the investigation that led to one. Recall 12V474000, 13V038000 is the campaign; its page carries the remedy.
Is PE12021 still open?
No. It closed on Mar 5, 2013 and led to recall 12V474000, 13V038000.
Which vehicles does PE12021 cover?
NHTSA opened it on 2 model years: 2009 Dodge RAM 1500, 2010 Ram 1500. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
