All 2 Known Issues
On the 2000-2006 Nissan Sentra, in rust-belt climates, the Sentra's steel fuel filler neck commonly corrodes where road salt and debris collect behind the left rear wheel area. Owners report a strong gasoline odor after fill-ups, visible rust holes, EVAP leak codes, and in some cases fuel dripping during refueling. Nissan issued a recall on certain vehicles for corrosion of the filler tube that could lead to fuel leakage.
Common Symptoms
- gasoline smell near left rear of vehicle
- fuel leak while filling tank
- check engine light with EVAP leak code
- visible rust on filler neck
- difficulty passing emissions inspection
How to Fix
Inspect the filler neck and vent tube for scaling, pinholes, and wet fuel residue, especially near the wheelhouse and hose connections. Replace the filler neck assembly and any degraded hoses or clamps, then clear EVAP codes and confirm the system passes a smoke test. In severe rust areas, inspect surrounding body metal and shield liners as well.

Parts and tips from 0+ owners who fixed this issue
- TipIf you live in a salt state, inspect the filler neck annually when rotating tires; catching surface rust early can prevent a roadside fuel leak.
- TipUse new clamps and vent hoses when replacing the neck, because old hoses often crack when disturbed.
On the 2000-2006 Nissan Sentra, many owners of this generation Sentra report recurring front brake pulsation caused by rotor thickness variation or heat-related warping. The issue often appears after relatively short service intervals, especially with low-quality replacement rotors or sticking caliper slide hardware. Drivers feel steering wheel shake and pedal pulsation during highway-speed braking, even when pads still have usable material.
Common Symptoms
- brake pedal pulsation
- steering wheel shake while braking
- front-end vibration during stops
- reduced braking smoothness
- uneven pad wear
How to Fix
Measure rotor runout and thickness variation, inspect caliper slides and pad wear patterns, and verify proper wheel lug torque. Replace or machine rotors if still within spec, install quality pads and hardware, and service or replace sticking calipers/slides as needed. Proper bedding-in and torque sequence help reduce repeat issues.

Parts and tips from 0+ owners who fixed this issue
- TipOwners commonly recommend premium coated rotors and ceramic pads instead of economy brake kits for longer life.
- TipTorque wheels by hand in a star pattern; over-tightened lug nuts can worsen rotor runout.
