2009 Dodge Ram 1500 fuel system problems
severe 12 complaints filed with NHTSA · avg repair $1,200 · see fuel system across all vehicles →
Among the 5 model years of Dodge Ram 1500 in our records for fuel system problems, this one ranks #3 by owner-complaint volume.
The failure pattern owners describe
Fuel tank strap corrosion dominates the complaints. Multiple owners report metal straps rusting where they attach to the subframe, causing the fuel tank to hang down or drop completely while driving. One owner heard a grinding noise as the corroded strap rubbed the driveshaft; another's tank began falling at highway speed. The problem appears across a wide mileage range but clusters around 149,000–180,000 miles. Chrysler issued recall 18V160000, but owners report it does not cover all vehicles or VINs, and dealers denied warranty help for out-of-coverage vehicles.
Fuel pump failures also appear: a loose power lead at the pump connection disconnects under vibration, killing the engine without warning codes. Owners also report fuel spraying out during refueling—up to half a gallon per fill-up—even after the pump shuts off. One service bulletin referenced replacing the EVAP canister, emissions monitor, vapor line, and filter; the problem persisted.
A low-mileage case describes fuel line fire at 8,000 miles. Corroded aluminum valve stems fractured tire pressure sensors, causing a tire blowout at highway speed.

Failure modes owners describe
Fuel tank strap corrosion and detachment
Metal fuel tank straps and their frame mounting points corrode, causing straps to fail and fuel tank to hang down or fall. Corrosion occurs between the strap and subframe, and moisture promotes rust that weakens the connection.
When: 149,000–180,000 miles; one case at 36,761 miles
Symptoms owners cite: Strange grinding or abnormal noise underneath truck; Fuel tank visibly hanging down from subframe; Strap detached from anchor point or pulled through frame; Frame anchor point disfigured
Repairs/costs cited: Fuel tank straps replaced. One owner temporarily secured tank with ratchet strap. Body shop repair required in some cases. One case covered under NHTSA Campaign 18V160000; others denied coverage.
Recalls/TSBs owners mention: NHTSA Campaign 18V160000 (Fuel System, Gasoline) issued; not all vehicles/VINs included. Chrysler acknowledged aluminum valve stem issues and planned return to rubber stems. Dealers denied warranty coverage for corrosion-related failures.
Fuel filler nozzle vapor lock / overfill spillage
Fuel spills out during refueling even when tank is full and pump shuts off. Owner reports up to half gallon spilled per fill-up. Service bulletin identified as requiring replacement of multiple vapor system components.
When: Recent onset, recurring every fill-up
Symptoms owners cite: Fuel sprays or spits out of filler neck when filling; Fuel spillage continues even after pump shuts off; Hazardous fuel odor and ground contamination
Repairs/costs cited: EVAP canister, emission system integrity monitor, vapor line, and filter all replaced; issue persisted. Alldata service bulletin referenced; dealer service department claimed unfamiliarity with issue.
Fuel pump power lead intermittent connection
Fuel pump power lead at the pump connection is loose and disconnects under vehicle vibration, causing fuel pump pressure loss and engine stall.
When: 8,000 miles (first incident 9/27/09, second incident 10/19/09)
Symptoms owners cite: Engine dies while stationary or driving (no warning); Engine will not restart immediately; No diagnostic codes stored in any module; No fuel pump pressure when tested
Repairs/costs cited: Fuel pump assembly replaced; loose power lead was corrected during replacement. Old part not available.
Fuel line fire
Fuel line catches fire underneath the vehicle at low speed. No further details provided on ignition source or line condition.
When: 8,000 miles
Symptoms owners cite: Fire underneath vehicle while driving
Repairs/costs cited: Vehicle taken to authorized dealer; not repaired.
Corroded aluminum valve stems causing tire pressure sensor failure
Aluminum valve stems corrode and oxidize due to reaction between aluminum stem and wheel/rim metal, causing stems to rust, fracture, and break off. This causes tire pressure sensor damage.
When: 36,761 miles
Symptoms owners cite: Tire pressure sensor light illuminates; Tire blows out suddenly at highway speed; Tire goes flat rapidly; Valve stem visibly corroded or broken
Repairs/costs cited: All four aluminum valve stems replaced with rubber valve stems.
Recalls/TSBs owners mention: Dealer informed consumer Chrysler had identified issues with aluminum stems and was switching back to rubber stems.
