What stands out
No new NHTSA fuel system complaint has been filed on this vehicle in over 12 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering fuel system on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
CHRYSLER GROUP: THERE ARE DIAGNOSTIC ENHANCEMENTS FOR THE FUEL SYSTEM.

The failure pattern owners describe
The 2005 Dodge Ram 2500 fuel system generates consistent complaints across 16 narratives, with the #4 fuel injector line rupture dominating the cluster. Owners describe pinhole leaks at the pressed fitting where the line connects to the injector, spraying fine mists of diesel that coat the engine bay, firewall, and undercarriage. The blue plastic retaining clamp designed to hold the line steady is loose and allows the tube to move freely inside it—defeating its purpose. Multiple owners report replacing the same line twice or three times in under a year, with one owner facing fuel spray incidents on the freeway with his family in the truck. Dealers confirm to owners that the #4 line is "very common to leak" yet issue no service bulletin.
Fuel contamination diagnosis emerges as a second major failure pattern. Dealers blamed contaminated fuel and recommended complete fuel system replacement ($11,000–$14,000), then voided warranties. Independent shops and Cummins service ruled out contamination or diagnosed only faulty injectors (~$1,700 repair). Owners requested fuel sample analysis; no dealer would perform or refer the test.
Owners also report accelerator pedal sticking (throttle-by-wire APPS binding), wiring harness failures to injectors, fuel tank fill-up malfunctions, and fuel injector line holder detachment. HEMI models experienced stalling resolved only by flash software. These are unverified consumer allegations reflecting diagnostic and repair inconsistencies across multiple dealerships.

Failure modes owners describe
Fuel injector line (#4) rupture and spray leaks
The #4 fuel injector delivery line ruptures or develops pinhole leaks at the pressed fitting connection near the injector. Diesel sprays as a fine mist into the engine bay, coating the engine, firewall, hood insulation, and undercarriage. Multiple owners report the blue plastic retaining clamp holding the line is loose and fails to prevent vibration damage. Owners describe strong diesel smells in the cab, white smoke from the engine bay, and in one case smoke inside the vehicle. One owner replaced the same line three times in under a year.
When: Ranges from under 27,000 miles to 100,000+ miles; multiple repeat failures on same vehicles within months to years
Symptoms owners cite: Strong diesel smell in cab; Fine mist or spray of fuel from #4 injector line; Fuel coating engine bay, firewall, hood insulation, undercarriage; White smoke from engine bay or wheel well; Smoke inside vehicle cabin; Fuel leaking from under truck; Rapid fuel gauge drop
Repairs/costs cited: Owners replaced the fuel injector line assembly (part cost cited as $52.60); multiple replacements required on affected vehicles. One dealer replaced injectors at ~$1,700. Dealers confirm #4 line is 'very common to leak.'
Recalls/TSBs owners mention: No recalls or TSBs mentioned. One dealer informed owner the #4 tube is 'very common to leak' but no service bulletin issued.
Fuel contamination and fuel system degradation
Multiple owners report fuel system problems initially blamed on fuel contamination, though diagnosis was inconsistent. Owners presented fuel identified as ULSD (ultra-low-sulfur diesel) with normal appearance; dealers claimed contamination and recommended complete fuel system replacement ($11,000–$14,000). When taken to independent shops or Cummins service, problems were either ruled out or diagnosed as faulty injectors only (~$1,700 repair). Dealers voided warranties claiming customer contamination. One owner had fuel samples requested but dealers refused to analyze samples or provide referrals for testing.
When: Starting around 27,000–30,000 miles for rough idle and hard starts; recurring 3 years later
Symptoms owners cite: Rough idle; Hard starting; Difficult to start engine; Stalling (one case with HEMI); Loss of power while driving
Repairs/costs cited: Chrysler recommended entire fuel system replacement ($11,000 parts list). Second Dodge dealer eliminated contamination as cause after 17 days. Cummins diagnosed and replaced 2 faulty injectors for ~$1,700; truck ran fine for 3 years. Second failure resulted in recurrence of injector problems. No fuel sample analysis performed by any dealer despite owner requests.
Recalls/TSBs owners mention: Chrysler referred case to corporate; recommended full fuel system replacement. Dodge voided warranty claiming customer contamination. Cummins service tech reported Dodge locked Cummins out of engines via programming and different connectors, preventing warranty service.
Fuel tank fill-up malfunction and tank failure
Consumer unable to properly fill fuel tank from day of purchase. Nozzle shut off after adding only four cents at a time, causing fuel to spill. Gas tank was replaced with a used tank, but replacement tank leaked due to inferior parts.
When: From initial purchase; replacement tank failure timing not specified
Symptoms owners cite: Nozzle shut-off during fueling; Fuel spillage during fill-up; Fuel leaking from replacement tank
Repairs/costs cited: Original tank replaced with used tank; replacement tank subsequently failed and leaked.
Fuel injector wiring harness and connector failures
Owner experienced loss of power and engine misfiring while driving. Mechanic diagnosed faulty wiring harness to injectors with poor connector design and replaced left back wiring harness. Described as faulty design of plugs going to injectors.
When: Unknown mileage
Symptoms owners cite: Loss of power while driving; Engine misfiring; Difficulty maintaining speed
Repairs/costs cited: Mechanic replaced left back wiring harness to injectors.
Fuel injection line holder detachment
The holder securing the fuel injection line detached without warning. At the time of report, the part was in high demand and unavailable at dealers.
When: 100,000 miles
Symptoms owners cite: Fuel injection line holder detached
Repairs/costs cited: Part unavailable at dealers at time of report.
Accelerator pedal sticking and not returning to neutral (throttle-by-wire APPS failure)
Accelerator pedal sticks and fails to return to neutral position when released. Described as poor pedal linkage. Truck uses throttle-by-wire system with no mechanical cable. Owner identifies Accelerator Pedal Position Sensor (APPS) as the binding point; the APPS is part of the pedal mechanism and serves as the hinge point.
When: Unknown mileage
Symptoms owners cite: Accelerator pedal sticks and does not return to neutral; Difficult to slow vehicle; Delayed pedal return to neutral; Binding in APPS hinge area
Sudden acceleration incidents
Consumer experienced sudden acceleration. Also reported the vehicle was becoming difficult to start. Issue was complicated by alleged fuel contamination diagnosis and subsequent injector replacement.
When: Unknown mileage
Symptoms owners cite: Sudden acceleration; Difficult to start
Repairs/costs cited: Fuel filter replaced; injectors later replaced after fuel contamination diagnosis.
Engine stalling (HEMI)
New 2005 Dodge RAM 2500 HEMI experienced stalling problems. Vehicle sat in shop for 6 weeks awaiting flash software release to solve the problem. No recurrence after flash update, but owner aware of other HEMI owners with same issue.
When: New vehicle
Symptoms owners cite: Stalling
Repairs/costs cited: Fixed by flash software update.
Recalls/TSBs owners mention: Flash software update released and applied to resolve stalling.

What owners are reporting 1 most recent
Shortly after speeding up a car in front of me hit their brakes. When I attempted to slow down it seemed that the accelerator pedal did not return to neutral and it was very hard to stop. After troubleshooting, I found out that the accelerator pedal was sticking and not returning to neutral after being depressed. Sometimes it would slowly return to neutral, other times it would stay depressed.…
