Hopefully it doesn't catch on fire before then.
Here's the official event timeline and fault details:
• In August, 2014, Chrysler opened an investigation into concerns of alternator-related engine stall while driving, increased steering effort, Antilock Brake System/Electronic Stability Control deactivation or fire / smoke in 2011-2012 MY Dodge Charger vehicles.
• Chrysler’s investigation analyzed alternators from vehicles exhibiting these conditions, and found indications of thermal fatigue of the alternators’ silicone diodes.
• Based on warranty data analysis, 160 Amp alternator part returns and a common control system design, Chrysler expanded the investigation scope to include WD, WK, LC, and the LX platforms, equipped with Electric Hydraulic Power Steering (“EHPS”), but limited to the 3.6L equipped with a 160 Amp Alternator.
• The root cause was determined to be thermal fatigue in the silicon diode within the alternator rectifier bridge, due to a combination of high operating temperatures and cyclical system load conditions, induced by the EHPS.
• This condition can lead to failure of the 20 Amp Silicon Rubber potted Diode(s) in the 160 Amp alternator.
• Failure mode of the 160 Amp alternators can range from no output, reduced output, or a fully shorted to ground condition.
• These modes can have corresponding variability in time to failure and warning to the driver.
• During certain low battery voltage conditions associated with the 160 Amp alternator silicon diode thermal fatigue failures, a rapid sequential thermal failure of the silicon diodes may cause engine stalling without the advanced warning provided by prolonged illumination of the “Charging System Indication Lamp” or by the EVIC, the electronic vehicle information center.
• Depending on the failure mode and timing, system voltage may drop to critical levels, disabling systems such as the, “Antilock 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).
