Vehicles Affected: Approximately 442,000 model-year 2011-14 Chrysler 300 sedans, Dodge Challenger coupes, Charger sedans and Durango SUVs, and model-year 2012-14 Jeep Grand Cherokee SUVs, all equipped with electrohydraulic power steering; a 5.7-liter or 3.6-liter engine; and a 160-, 180- or 220-amp alternator
The Problem: The alternator may suddenly fail, causing the vehicle to stall without warning and increasing the risk of a crash. The alternator also may short circuit, increasing the risk of a fire.
In a statement, Chrysler, Dodge and Jeep manufacturer Fiat Chrysler Automobiles said alternators supplied to the automaker may be subject to premature diode wear following frequent load cycling, at or near maximum amperage, in hot ambient temperatures. This wear may cause illumination of an instrument-cluster warning light 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,” FCA stated. “Premature component wear may also compromise function of a vehicle’s antilock braking system and/or electronic stability control. However, basic braking capability is unaffected.”
The automaker said it is aware of two “potentially related” accidents but no injuries.
The Fix: Dealers will inspect the alternator and, depending on the part number, replace it for free.
What Owners Should Do: FCA will begin notifying owners Aug. 24. Owners can call the automaker at 800-853-1403, the National Highway Traffic Safety Administration’s vehicle-safety hotline at 888-327-4236 or visit www.safercar.gov to check their vehicle identification number and learn more.
