FCA US LLC is voluntarily recalling an estimated 467,480 SUVs worldwide to install new a relay circuit that improves fuel-pump relay durability.
FCA US engineers have determined a condition identified in a previous investigation may extend to additional vehicles. The previous investigation, which led to a recall, traced a pattern of repairs to fuel-pump relays that are susceptible to deformation. This may affect fuel-pump function, preventing a vehicle from starting, or leading to engine stall.
Of the two scenarios, the no-start condition is the more common. FCA US is unaware of any related injuries or accidents.
The fuel-pump relay is located inside the Totally Integrated Power Module (TIPM), which also helps manage other vehicle functions. None of these other functions, including air-bag deployment, is affected by the fuel-pump relay.
The new campaign affects an estimated 338,216 vehicles in the U.S.; 18,991 in Canada; 10,829 in Mexico and 99,444 outside the NAFTA region.
Covered are model-year 2012 and 2013 Dodge Durango full-size SUVs and non-NAFTA 2011 Jeep Grand Cherokee mid-size SUVs equipped with 3.0-liter diesel engines. Current vehicles with EcoDiesel engines are not affected.
FCA US will advise affected customers when they may schedule service, which will be performed at no cost.
