FCA US is voluntarily recalling an estimated 467,480 SUVs worldwide to install new a relay circuit that improves fuel pump relay durability.
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.

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 airbag deployment, is affected by the fuel-pump relay.
The new campaign affects an estimated 338,216 vehicles in the US; 18,991 in Canada; 10,829 in Mexico and 99,444 outside the NAFTA region.
The vehicles covered are model year 2012 and 2013 Dodge Durango full-size SUVs and non-NAFTA 2011 Jeep Grand Cherokee mid-size SUVs equipped with three litre diesel engines. Current vehicles with EcoDiesel engines are not affected.
