Dodge preliminary evaluation PE14022
Alternator failure. NHTSA’s Office of Defects Investigation opened this preliminary evaluation about the alternator/generator/regulator on 2 model years (2011–2012). Opened Jul 22, 2014, closed Nov 6, 2014 after 4 months. It led to safety recall 14V634000. became a recall
What NHTSA says
Source: Office of Defects Investigation, as filedOn July 22, 2014, the Office of Defects Investigation (ODI) opened PE14-022 to investigate 14 complaints (VOQs) alleging incidents of alternator failure resulting in engine stall while driving in model year (MY) 2011 through 2012 Dodge Charger vehicles. The MY 2011 through 2012 Dodge Charger vehicles were sold with three different engine options:1) 3.6L V6 (VIN8 = G), 88,766 vehicles; 2) 5.7L V8 (VIN8 = T), 38,615 vehicles; and 3) 6.4L V8 (VIN8 = J), 2,406 MY 2012 vehicles. The 14 VOQs identified in the PE14-022 opening resume involve 13 vehicles with 3.6L V6 engines and 1 vehicle with unknown engine (no VIN provided).In an October 7, 2014 letter to NHTSA, Chrysler described a safety defect condition that could result in rapid alternator failure having limited or no detection in approximately 434,581 MY 2011 through 2014 Chrysler 300, Dodge Charger, Dodge Challenger, Dodge Durango and Jeep Grand Cherokee vehicles equipped with 3.6L engines and 160 amp alternators (NHTSA Recall No. 14V-634, Chrysler P60).The subject alternators are used in vehicles equipped with 3.6L V6 engines and without towing packages. According to Chrysler, the silicone diodes in the alternator rectifier bridge may experience thermal fatigue due to cyclic loading from the Electric Hydraulic Power Steering (EHPS) system, eventually resulting in no output, reduced output, or a fully shorted to ground condition. These failure modes vary in their time to failure and warning to the driver. Depending on the failure mode and timing, system voltage may drop to critically low levels, disabling systems such as the Anti-lock Brake System/Electronic Stability Control, Engine Control Module/Central Body Controller, or a total vehicle electrical system shut down (in the event of a short to ground failure mode).Analysis of complaints to ODI and Chrysler identified a total of 146 incidents of alternator failure resulting in engine stall while driving in MY 2011 through 2012 Dodge Charger vehicles, including 142 involving vehicles equipped with the 3.6L V6 engines (1.6 IPTV) that were included in 14V-634 and 4 involving vehicles with 5.7L V8 engines (0.1 IPTV), which are equipped with different alternators. Analysis of all alternator failure complaints found that approximately 48 percent of VOQs and 21 percent of Chrysler complaints involved allegations of engine stall. Many (98) complaints reported fire and/or smoke, but analysis of these determined that they involved thermal damage to the alternator diode and did not identify any incidents involving damage beyond the alternator assembly. One VOQ identified in the opening resume for PE14-022 alleged a crash, but further evaluation determined that this involved a minor rear-end impact with slight bumper damage. This investigation is closed based on Chrysler's decision to conduct a safety recall.

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 PE14022 a recall?
No — it is the investigation that led to one. Recall 14V634000 is the campaign; its page carries the remedy.
Is PE14022 still open?
No. It closed on Nov 6, 2014 and led to recall 14V634000.
Which vehicles does PE14022 cover?
NHTSA opened it on 2 model years: 2011 Dodge Charger, 2012 Dodge Charger. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
