Share Download Print Statement: Alternator Diode July 14, 2017 , Auburn Hills, Mich. - FCA US LLC is voluntarily recalling an estimated 442,214 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. The diode wear may cause illumination of an instrument-cluster warning light and/or the presence of a burning odor or smoke. Customers who observe these warning signs should contact their dealers; continued vehicle use may result in engine stall. Premature component wear may also compromise function of a vehicle’s anti-lock braking system (ABS) and/or electronic stability control (ESC). However, basic braking capability is unaffected. FCA US is aware of two potentially related accidents, but no injuries. The campaign is limited to vehicles equipped with electro-hydraulic power steering. Affected customers will be notified by first-class mail and advised when they may schedule service, which will be provided free of charge. Affected are certain 2011-2014 Chrysler 300 and Dodge Charger sedans, Dodge Challenger coupes, Dodge Durango SUVs and 2012-2014 Jeep Grand Cherokee SUVs. An estimated 29,625 vehicles of the same make, model and year will be recalled in Canada, as will an estimated 7,879 in Mexico, and an estimated 85,929 outside the NAFTA region. FCA US urges customers, as always, to follow the instructions in their recall notices. Mailing is scheduled to begin next month. Customers with questions or concerns may call the FCA US Customer Care Center at (800)-853-1403.
