The problem can cause the vehicles to stall or potentially cause a fire.
Fiat Chrysler Automobiles U.S will recall a total of 86,132 vehicles for a fault with the alternator. The campaign will include 74,833 units in the United States, 10,077 in Canada, 1,088 in Mexico, and 134 outside the NAFTA region. The affected vehicles are certain examples of the:
- 2007-2013 Ram 2500 and 3500
- 2007-2013 chassis cab variants of the Ram 3500, 4500, and 5500
- 2011-2014 Dodge Charger Pursuit
A diode in the alternator in these models can wear out prematurely from frequent use near maximum amperage in hot climates. This can eventually cause the component to short circuit, which would lead to the vehicle stalling. There's also the possibility of the part overheating and causing a fire. FCA US believes the problem is far more likely in fleet vehicles because of their continual use, rather than for regular consumers.
The automaker reports that it has a report of "a single potentially related injury." There are no accounts of any accidents, though. The company discovered the issue during an investigation of fleet-vehicle performance.
FCA U.S will contact owners soon about setting up a service appointment for fixing the issue.
Recalls for these commercial vehicles are fairly rare. FCA included the trucks in its regional campaign earlier in 2016 to replace the Takata airbag inflators that could potentially rupture. The affected parts lacked a chemical for absorbing moisture inside them. This was especially problematic because researchers found exposure to high heat and humidity was a factor in whether the components would burst. There were no reported explosions in any of FCA's vehicles, though.
The automaker also had a campaign that included the pickups in 2015 when FCA recalled 1.4 million vehicles for a security hole in the infotainment system software. Researchers were only able to hack a single Jeep Cherokee on the road, but the incident gained national attention. The affected owners received a USB stick that contained the updated software.

Statement: Alternator Diode
October 18, 2016 , Auburn Hills, Mich. - FCA US LLC is voluntarily recalling an estimated 74,833 vehicles in the U.S. to replace their alternators.
Certain alternators supplied to the Company may be subject to premature diode wear following frequent load cycling, at or near maximum amperage, in hot ambient temperatures – conditions more consistent with fleet-vehicle usage than that of retail customers.
Such conditions increase the potential for short-circuit in these alternators, the outcome of which may be engine stall and/or vehicle fire. FCA US is aware of a single potentially related injury, but no accidents.
This campaign was prompted by an FCA US investigation of fleet-vehicle performance.
Affected are certain 2007-2013 Ram 2500 and 3500 pickups; 3500, 4500 and 5500 chassis cabs and 2011-2014 Dodge Charger Pursuits. Also included in the recall are an additional 10,077 vehicles in Canada; 1,088 in Mexico and 134 outside the NAFTA region.
Affected customers will be advised when they may schedule service, which will be performed free of charge. Customers with questions or concerns may call the FCA US Customer Care Center at (800)-853-1403.
