The failure pattern owners describe
Buyer takeaway: A 2007 Chrysler 300 with fuel-system issues is a risky buy—multiple owners report stalling after refueling with no reliable fix found, fuel gauge failure, and tank/pump housing problems. Even dealer intervention often doesn't resolve the stalling, and out-of-pocket costs can run $500–$1,100 with no guarantee of success.
Owners report a fuel system plagued by stalling episodes tied to refueling. Most describe the car shutting down after filling the tank or adding even small amounts of fuel—sometimes at idle, sometimes at highway speed. Multiple owners took the car to dealers and independent shops; no clear cause was found, though one owner had to pay $1,100 after being told the repair might not even work. Another faced a dealer estimate of $1,100 for a fuel tank replacement due to the tank rubbing against the frame; they went elsewhere and paid $500.
Fuel gauge malfunction crops up in two accounts: one owner was stranded on I-95 when the gauge read 1/4 tank but the car wouldn't start; adding fuel was the only remedy. Another owner struggled with a fuel cap that leaked repeatedly, developing a check-engine light; Chrysler headquarters told them it was not a safety issue.
A few owners mention engine start/stall problems after refueling coupled with jerking and shaking as if the transmission was hunting for a gear, along with check-engine lights. One owner reported fuel fumes inside the car and garage traced to a cracked fuel pump mount housing. A rough idle and failed transmission work from the first complaint may not be fuel-system related but appear here due to clustering.

Failure modes owners describe
Stalling after refueling
Vehicle shuts down or stalls repeatedly after filling the tank or adding fuel, occurring at various driving conditions including intersections, highways, and at idle.
When: Immediately after refueling or within the first drive after fuel addition; affects vehicles across mileage range (50,000–100,000+ miles reported)
Symptoms owners cite: Engine cuts off while driving after refueling; Stalling at red lights, intersections, and highway speeds; Engine starts then stalls after restart; Hesitation or stumbling immediately post-refuel
Codes mentioned: Check engine light (cause unspecified in narratives)
Repairs/costs cited: One owner paid $1,100 at dealer with no guarantee fix would work; another paid $500 at independent shop. Multiple shops unable to diagnose root cause.
Recalls/TSBs owners mention: No recalls, TSBs, or warranty assistance mentioned. Manufacturer notified in at least one case but offered no assistance.
Fuel gauge malfunction
Fuel gauge reads incorrectly, failing to register fuel added to the tank or showing empty/low when fuel is present, causing stalling or starting difficulty.
When: Intermittent; one reported incident at highway speed (I-95), another after multiple fill-ups
Symptoms owners cite: Gauge reads 1/4 tank but vehicle acts out of fuel; Gauge does not rise after adding fuel; OBD light illuminates coinciding with fuel gauge issue
Codes mentioned: OBD light (likely fuel sender/gauge circuit issue, not specified in narratives)
Repairs/costs cited: No repair cost cited; one owner added fuel ($50 total, 12 gallons) before gauge reflected near-full
Leaking fuel cap
Fuel cap develops leaks allowing fuel and vapors to escape, causing odor and triggering check-engine light.
When: Recurring issue; one owner experienced it two years in a row at same dealership
Symptoms owners cite: Fuel odor inside car and garage; Visible fuel leak at cap; Check engine light illumination
Codes mentioned: Check engine light (EVAP-related, not specified in narratives)
Repairs/costs cited: Cap replacement cost not stated; owner had to pay out-of-pocket despite warranty period questioned.
Recalls/TSBs owners mention: Chrysler headquarters told owner it was not a safety issue and not covered under warranty.
Fuel tank rubbing frame
Fuel tank physically contacts the frame, causing abnormal deceleration and check-engine light.
When: Around 100,000 miles
Symptoms owners cite: Abnormal deceleration; Check engine light at startup
Repairs/costs cited: Dealer estimate $1,100 for tank replacement; independent shop completed replacement for $500.
Recalls/TSBs owners mention: Manufacturer was notified but no details on any recall or TSB offered.
Cracked fuel pump mount housing
Upper fuel pump mount plastic housing develops hairline crack, leaking fuel and creating fumes.
When: Mileage not stated
Symptoms owners cite: Fuel odor inside car and garage; Visible fuel leak at pump mount
Repairs/costs cited: Owner identified the cracked housing themselves via inspection; repair cost not stated.

At what mileage does the fuel system typically fail?
Across the 8 complaints that reported odometer mileage, most fuel system failures cluster between 50,000 and 116,035 miles, with the median around 115,000. A quarter of owners report trouble before 50,000; a quarter make it past 116,035. 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?
No active recalls currently cover fuel system issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
