Most common causes on the 2023 Nissan Rogue

Ranked from 660 NHTSA owner complaints filed for this vehicle.

Sort by:

1
Cracked or deteriorated EVAP hose/vent line
High severity
A high volume of raw-fuel-smell complaints in the cabin and engine bay on this generation points to a leaking EVAP vent or purge hose; repeat hose-replacement attempts have been reported for the same symptom.
Reported in 14 NHTSA complaints
Parts:EVAP hose
2
Fuel/vapor line fitting not fully seated after a recall repair
Medium severity
One owner had a 'gas line recall' fix that did not fully resolve the smell, suggesting a fitting or clip on the fuel/vapor line was not fully seated during the repair.
Reported in 1 NHTSA complaint
Parts:fuel line clip
3
Purge valve stuck open or leaking
Medium severity
A purge valve that doesn't seal lets tank vapor bleed continuously into the intake/cabin area even at idle; test with a scan tool commanded purge test.
Common cause
Parts:purge valve
4
Cracked or saturated charcoal canister
Medium severity
A cracked canister housing or one overwhelmed by repeated over-fueling can vent raw fuel vapor instead of storing it; inspect the canister and its seals.
Common cause
Parts:charcoal canister
5
Loose or damaged gas cap
Low severity
A cap that doesn't seat and seal properly is the simplest source of a small EVAP leak and should be checked first.
Common cause
Parts:gas cap
6
Rusted or corroded filler neck
Low severity
Corrosion can perforate the filler neck and let vapor escape; inspect for rust-through, especially in salt-belt regions.
Common cause
Parts:filler neck

Hard start after fueling in some cases

What to check before replacing parts

Tighten and inspect the gas cap

Look for: A cap that doesn't click to full tightness, has a visibly cracked or flattened seal, or is simply missing is the single most common cause of a small EVAP leak — rule it out first.

Smoke-test the EVAP system

Look for: Because this is a small leak, expect only a thin wisp of smoke or a faint hiss at one spot (a hose, seam, or valve) rather than an obvious cloud — look closely and take your time.

Check purge valve sealing

Look for: A purge valve that doesn't hold vacuum when commanded closed lets a small amount of air bleed through, which the system reads as a leak during its self-test.

Inspect hoses near the tank and engine bay

Look for: Look for small cracks, soft/collapsed spots, or a hose that has pulled loose slightly at a fitting — any of these can leak just enough to trip a small-leak code without an obvious fuel smell.

Verify vent valve operation

Look for: A vent valve that doesn't seal fully when commanded closed prevents the system from holding vacuum during its self-test, which reads as a small leak even with no physical leak in the hoses.
