One problem related to other fuel system pump has been reported for the 2011 Dodge Nitro. The most recently reported issues are listed below.
My vehicle intermittently will shut off or deny power to the fuel pump, it also will intermittently flash warning signs, and turn the wipers on indefinitely. The issues have all been traced back to the power module and more specifically nonservicable relays. I've contacted the dealership and Chrysler and neither have an eta on the part should I order one. Mostly it happens while stationary but it caused the vehicle to stall on the highway twice. It stated doing this in fall of 2015 but I couldn't properly diagnosis it until March due to it being intermittent.
