The 2020 Ram 1500 fuel system complaints cluster around two main issues: high-pressure pump failure tied to recall 22V767000, and fuel filler problems.
On the pump side, owners describe loss of power while driving, hesitation on acceleration, stalling, and shuddering—sometimes accompanied by a "Service High Pressure Fuel Pump" message or check engine light. Failures occurred anywhere from 14,000 to 104,000 miles. Multiple owners received recall notification but dealers told them parts were on national backorder, with some quoted wait times exceeding a year and a half. Notably, a few owners report the pump failing again after the recall repair was completed.
The fuel filler issues span refueling nozzles that shut off repeatedly, fuel spilling out of the filler neck (especially in cold weather below 50 degrees), and in one case, a sticking rollover valve that caused tank replacement. Dealer repairs—including filter replacement, pump replacement, and full tank/delivery-line replacement—have not permanently fixed the spillage in all cases. One owner reports having the entire fuel system replaced at 12,555 miles, only to have the same problem return 9,000 miles later.
A fractured DEF system and an unexplained dual airbag deployment incident also appear in the cluster, though less frequently.

High-pressure fuel pump fails or starts failing, causing loss of power, hesitation, stalling, check engine light, and Service High Pressure Fuel Pump messages. Occurs under NHTSA recall 22V767000 but replacement parts are on national backorder for extended periods. Some vehicles have experienced pump failure recurrence even after recall repair.
When: Between 14,000–104,000 miles
Symptoms owners cite: Vehicle hesitates or fails to accelerate as intended; Vehicle shudders, vibrates, almost stalls while driving; Loss of motive power while driving; Vehicle stalls and fails to restart; Check engine warning light illuminated; Service High Pressure Fuel Pump message displayed; Power loss after recall repair in some cases
Codes mentioned: High-pressure fuel pump failure diagnosed by dealers
Repairs/costs cited: Pump replacement required; parts unavailable on national backorder for up to 1.5 years per dealer estimates. One vehicle experienced recurrence at 35,000 miles after recall repair, and another at 104,000 miles after recall repair.
Recalls/TSBs owners mention: NHTSA Campaign Number 22V767000 (Fuel System, Gasoline, Engine); parts unavailable
Fuel cannot enter the tank or fuel splashes out during refueling. Caused by rollover valve sticking or fuel filler issues that prevent proper fuel entry and cause spillage, especially in cold weather below 50 degrees. Replacing pump and tank does not permanently fix the issue in some cases.
When: As early as 5,000 miles; recurring at 30,000+ miles after repair
Symptoms owners cite: Fuel splashes out and cannot enter vehicle during refueling; Fuel nozzle constantly shuts off during refueling; Fuel leaks out of fuel filler neck, spilling down vehicle side; Fuel spillage occurs especially in temperatures below 50 degrees; Refueling requires very slow pump operation to prevent spillage; No warning lights illuminated
Repairs/costs cited: Dealers have replaced fuel pump, gas tank, fuel delivery line, and filter, but failure persists in some vehicles. One owner reports having entire fuel tank and delivery line replaced at 12,555 miles, then same issue recurred at 21,555 miles.
Recalls/TSBs owners mention: Manufacturer stated no recall exists; customers report Dodge claims no recall for rollover valve issue
DEF system fractures and causes burning odor from underneath vehicle. Error message displayed instructing owner to take vehicle to dealer within 200 miles.
When: 40,000 miles
Symptoms owners cite: Burning odor around exterior of vehicle from underneath; Error message displayed: take to dealer within 200 miles
Repairs/costs cited: DEF system replacement required; vehicle remained at dealer for additional diagnostic testing, no repair completion reported
