Gas overflows when filling tank on my 2008 Dodge nitro. I have heard this is most likely caused by a valve in the gas tank that is there to prevent an explosion in the event of a rollover. The valve is defective and thus, the gas spills out. *tr

What stands out
Owners have filed 65 fuel system complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Among the 5 model years of Dodge Nitro in our records for fuel system problems, this one ranks #2 by owner-complaint volume.
The failure pattern owners describe
Owners consistently report fuel overflow from the filler neck during refueling on 2008 Dodge Nitro vehicles. The malfunction occurs when the pump's automatic shutoff clicks, after which gasoline shoots back out of the tank—sometimes in amounts approaching a half gallon or more—spraying onto the vehicle's exterior, the owner's body and clothing, the pump handle, and the ground below. This happens repeatedly across multiple fuel stations, different gas types, and various pumping speeds; some owners report it occurs every single fill-up, others notice it beginning months into ownership.
Owners and mechanics have identified a faulty rollover check valve (also called a vent valve) inside the fuel tank as the root cause. The valve is designed to prevent explosions in rollover accidents but is malfunctioning, allowing fuel to be forced back up the filler neck instead of venting safely. One owner cited TSB 14-001-09, confirming Chrysler is aware of the defect.
The primary repair mentioned is complete fuel tank replacement, typically quoted at $1,100 or more, often declined by owners as out-of-warranty work. One owner reported Chrysler offered partial cost assistance. Another had an evaporator canister replaced—which did not solve the problem—before moving to tank replacement. Reported damage includes paint discoloration and fading of plastic trim from repeated gasoline exposure.
Owners emphasize the acute fire hazard posed by flammable liquid pooling at gas stations and on vehicles, alongside environmental contamination and exposure to toxic fumes.

Failure modes owners describe
Fuel tank overflow at fill-up due to faulty rollover check valve
Gasoline sprays back out of the filler neck immediately after or during the automatic pump shutoff, covering the vehicle, person, and ground. The root cause is a defective rollover/vent valve inside the fuel tank that fails to manage pressure correctly during normal refueling.
When: Occurs during refueling, typically after pump clicks off or when nozzle is withdrawn. Reported from early ownership (thousands of miles) through higher mileage (130,000+ miles).
Symptoms owners cite: Fuel sprays or gushes out of filler neck after pump shuts off; Fuel shoots backward with moderate force onto vehicle and ground; Overflow volume estimated at 0.5 to 2+ cups per incident; Occurs regardless of fuel type, pump speed, station, or manual vs. automatic filling; Happens at every fill-up for affected vehicles; No correlation with topping off or aggressive pumping
Repairs/costs cited: Complete fuel tank replacement quoted at approximately $1,100. One owner reported evaporator canister replacement did not resolve the issue and tank replacement was necessary. Chrysler offered partial cost assistance (less than 50% of repair cost) in at least one case, which owner declined. One tank replacement reported as completed.
Recalls/TSBs owners mention: TSB 14-001-09 acknowledges the issue exists per one owner's report. Chrysler service acknowledged awareness of 'default with the rollover check valves' in at least one case and offered partial cost assistance. Dealer service at multiple locations reported being familiar with the problem ('we have heard of this before'). No manufacturer recall issued despite 65 complaints in cluster and widespread discussion on Nitro forums. Jeep Liberty with identical tank received a recall for the same defect, but Dodge Nitro was not recalled.

This is a severe fire risk, not to mention the vapors I, and…
The gas tank overflows when filling. The auto shutoff on the gas tank is faulty, this is a problem with the same year Jeep libertys with the same tank. The 20" chrome wheels flake and corrode even when kept clean and out of the elements. This must be fixed! *tr
When I fill up my tank at any gas station, I will put the gas nozzle in the gas filler neck, and have it fill up. When the gas tank reaches it's maximum level, the gas nozzle will automatically 'click' off, however, the gas will overflow out the gas filler neck and spray out all over the ground and down the car, I'm thinking that something so flammable as gasoline spraying out and dripping on…

Common questions
How serious is the fuel system problem on the 2008 Dodge Nitro?
It's a documented issue but not catastrophic. 65 complaints have been filed. Repairs average $1,200 and most owners catch it before it causes a breakdown.
At what mileage does the fuel system typically fail?
Across the 54 complaints that reported odometer mileage, most fuel system failures cluster between 30,000 and 60,000 miles, with the median around 40,500. A quarter of owners report trouble before 30,000; a quarter make it past 60,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $1,200 for fuel system repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to fuel system?
