Fiat Chrysler Automobiles (FCA US LLC) has issued a voluntary recall of an estimated 74,833 vehicles in the U.S. to replace their alternators. Overall, the manufacturer is recalling more than 86,000 police cars and trucks.

The recall covers 10,777 units in Canada, 1,088 in Mexico, and 134 outside the North American Free Trade Agreement (NAFTA) region. Also included are certain:

  • 2007-2013 Ram 2500 and 3500

  • 2007-2013 chassis cab variants of the Ram 3500, 4500, and 5500

  • 2011-2014 Dodge Charger Pursuit

Chrysler said that certain alternators supplied to the company may be subject to premature diode wear after frequent load cycling and constant exposure to hot temperatures. Such conditions increase the potential for short-circuit in these alternators causing fire.

FCA US claims that there is only one reported case of injury related to the issue. Meanwhile, no accident has been reported.

Customers that own vehicles with faulty alternator will be advised when they may schedule service, which will be performed free-of-charge.
